The Ultimate Guide To Watering Your Bonsai Tree

Watering Your Bonsai Tree

Bonsai trees are beautiful and elegant, but they can also be difficult to take care of. If you want your bonsai tree to stay healthy and look great, it is important that you properly maintain its environment so that it receives enough water. In this post, we will get you guided on watering your bonsai tree and how often a bonsai tree needs watering in order to thrive.

Watering Your Bonsai Tree

Many people ask, “how often should I water my bonsai tree?”.

A bonsai plant has a very specific watering schedule. You should plan to water it every other day or so, and never allow the soil surface to dry out completely in between watering (about 2-3 days is best).

During hot, dry weather, you may need to water your tree more often. If the soil feels very dry to the touch, it’s time to water it.

Watering bonsai trees can be tricky because overwatering can be just as harmful as under-watering. Be sure to allow the soil to dry out in between watering. Here are some watering tips:

  1. Use a watering can with a fine rose or tip to avoid hitting the leaves of your bonsai tree when you water.
  2. Don’t use cold water when watering newly transplanted bonsai trees. Cold water will shock the roots, causing the cells inside them to collapse and restricting growth.
  3. Water your bonsai tree in the morning so the leaves have time to dry before nightfall. Wet leaves are more susceptible to fungal diseases.
  4. If you’re going on vacation, ask a friend or neighbor to water your bonsai for you.
  5. Bonsai trees like to be root-bound, so don’t over-pot them. When you water your bonsai tree, the roots will absorb most of the water (80%). The surface soil will dry out very quickly because most of the water is retained in the root zone.
  6. When you’re away on vacation, be sure to leave enough time for someone to visit your bonsai every 2-3 days to water it.
  7. When you transplant your bonsai, be sure to water it well after the transplant. You can place the bonsai in a shady spot for a day or two to help reduce stress from the transplant.

The Importance of Watering Your Bonsai Plant

One of the most important items you should always remember is to water your Bonsai plant. The key for a healthy bonsai plant is giving it enough water, but not too much. If you give your bonsai too much water from time to time, this could kill them as well as the roots will rot and eventually kill the tree.

  • Bonsai plants are delicate and require a different way to water compared to your common household plant. You want to submerge the entire container that holds your bonsai into a bowl of water and then allow it to drain completely into the tray, or sink. If you do not let all of the excess water drain out, the plant will begin to rot and die. This is why it is vital that you use a tray underneath your container for proper watering.
  • It is also important to note that it is vital to let the excess water drain out of your bonsai container. You will eventually want to turn your plant so that all of the roots are exposed to the air for about an hour or two after watering, but not right away. Once you have removed most of the water from your container,
  • Watering bonsai plants during the winter months is not an exception. You want to water them just as much during winter, but you have to be extremely careful when doing so. To tell if your bonsai needs water, you can use the ‘finger test’. Stick your finger in the soil and if it feels dry then it’s time to water.
  • Bonsai plants are not the only ones that need to be watered; your houseplants also need to be watered on a regular basis. Make sure to check the soil of your houseplants daily and water them when they need it. It is important to make sure that your bonsai and other houseplants do not sit in the same spot, or the bonsai will take all of the nutrients from the soil and leave little for your other plants.

The key to watering your bonsai is to be consistent. Water them every day if possible, and always make sure to check the soil to see if it is dry before watering. Following these simple tips will help your bonsai thrive for years to come!

Factors to Consider When Watering Your Bonsai Tree

There are many things to consider when watering your bonsai tree. For example, what type of soil is the tree planted in? How often does it rain in your area? What is the size and shape of the pot?

In general, most bonsai trees should be watered every other day.

Here are some more detailed factors…


Bonsai trees need to be fertilized regularly in order to stay healthy. There are many different types of fertilizer on the market, so it is important to choose one that is best suited for your tree’s needs. Be sure to follow the instructions on the package carefully. Fertilizer is considered because the leaves and branches of a bonsai tree are to be.

Plant Size

If you have a large bonsai tree, it should be watered more often than small ones. This is because it takes longer for the soil to dry out on bigger trees. The size of the pot also matters; a pot that is too small will dry out more quickly than a pot that is larger.


The climate in your area also affects how often you need to water your bonsai tree. In areas that have a lot of rain, the tree may not need to be watered as often as in an area that is dry.


Bonsai trees need plenty of light in order to thrive. They should be placed in a location where they will receive several hours of sunlight each day. If you live in a climate with harsh winters, you may need to move your tree indoors during the winter months so it will receive enough sunlight.

Distance from the Water Source

The further a bonsai tree is from a water source, the more times you may need to water it each day. If possible, consider moving your bonsai pot closer to or directly over a sink or garden hose. This can help lessen the time and effort that goes into watering a bonsai tree.

Water Temperature

As a general rule, you should never water your bonsai trees with cold or ice-cold water. If the temperature is below 50 degrees Fahrenheit, wait until it warms up to water the tree. The water must also not be higher than 70 degrees Fahrenheit. The best type of water to use on your bonsai is spring water or room-temperature tap water.

Type of Soil

The type of soil that your bonsai tree is planted in also affects how often it needs to be watered. Soils that are made for bonsai trees hold water more than regular soil, so the tree will not need to be watered as often.

Container Size

As mentioned above, the size of the pot also affects how often you need to water your bonsai tree. If you have a large bonsai tree in too small of a pot, it will dry out faster than if it were planted in a larger one.

Now that you know some of the things to consider when watering your bonsai tree, it will be easier to keep your tree healthy and looking beautiful. Remember to fertilize regularly, place in a location with plenty of sunlight, and use room-temperature water.

Type of Water for Your Bonsai Plant

Bonsai need pure rainwater to keep their soil healthy and clean. So, if you have access to a garden or even just an open space in your own backyard, make sure that it doesn’t go wasted by collecting enough rainwater. If you don’t have rain water available, using regular tap water is fine unless it contains too many chemicals and is undrinkable.

One way to get rid of the chlorine in your tap water is by letting it sit overnight. It’s not just a matter of waiting for one hour; you have to give them 24 hours so that all those unwanted gas molecules can evaporate.

If you have a fish tank (freshwater) or pond, use some of that water to water your bonsai. The nutrients from the fish are beneficial for trees!

When you plant a bonsai, it’s not just about the soil. You need to consider what kind of water your tree will be drinking and whether that contains all the minerals needed for healthy growth!

More Ways to Handle Your Bonsai

Aside from watering, there are other ways to handle your bonsai tree:

Fertilizing – Fertilize your bonsai with a balanced fertilizer every other week.

Pruning – Pruning is an essential part of bonsai care. You should prune your bonsai tree regularly to keep it in shape and promote healthy growth.

Repotting – Repot your bonsai tree every 2-3 years, or when the pot feels too tight for the roots.

Fertilizing Your Bonsai Tree

Bonsai trees need to be fertilized regularly to stay healthy. You can use a liquid or solid fertilizer, but be sure to follow the instructions on the label.

  1. Fertilize your bonsai tree every 2-4 weeks, using a light dose of fertilizer (half the recommended strength). Over-fertilizing can be harmful, so be careful not to give your tree too much fertilizer.
  2. Be sure to water your tree thoroughly after fertilizing. Fertilizer can cause the soil to become overly moist and lead to root rot.

Pruning Your Bonsai Tree

Prune your bonsai tree regularly to maintain its shape and size. Pruning also helps keep the tree healthy by removing dead or diseased branches.

  1. Pruning your bonsai tree should be done during its dormant season (winter is best). You can use sharp scissors or pruning shears to cut the branches.
  2. When pruning your bonsai tree, be sure to make clean cuts and remove any dead or diseased branches. Make sure the branch is properly cut off, so that there is no stub left on the branch.
  3. If you’re not sure how to prune your bonsai tree, you can find many instructional videos online.

Repotting Your Bonsai Tree

Bonsai trees need to be repotted every few years, depending on the size of the pot and the growth of the tree. When you repot your bonsai, be sure to use a pot that is only slightly larger than the current pot.

  1. Repot your bonsai in late winter or early spring, when the tree is still dormant. Be sure to water the tree well after repotting.
  2. When repotting your bonsai tree, be sure to remove any wire or string wrapped around the root ball. Remove the packing material as well (small rocks and pieces of charcoal). If your soil is too compacted, you can gently tease it apart with your hands. Be sure to scrape off any old soil from the root ball before repotting your bonsai.
  3. When you’re finished repotting, be sure to water the tree well. You can place the bonsai in a shady spot for a day or two to help reduce stress from the transplant.

Bonsai trees are beautiful plants that can add a touch of elegance to any home or office. But keeping a bonsai tree healthy requires a bit of work and knowledge. By following these simple tips, you can ensure that your bonsai tree stays healthy and looking beautiful.

Watering Your Bonsai Tree

Bonsai Diseases and Pests

It is important to be on the lookout for bonsai diseases and pests. Insects such as aphids feed off of your tree’s leaves, causing them to turn yellow or brown. If you see any insects eating away at your plant, use a pesticide spray that contains neem oil or an insecticide soap solution to get rid of them.

Bonsai diseases can be caused by a number of things, including over-watering, under-watering, and using the wrong type of soil. If you think your tree may have a disease, take it to a bonsai specialist for diagnosis and treatment.

Types of Bonsai Diseases and Pests

There are a number of bonsai diseases and pests that affect your prized plants. They include at least one from the following list:

  • Root rot – symptoms include yellow leaves, brown tips on leaves, wilting, and stunted growth. Treat root rot by giving it fresh soil with good drainage and air circulation, as well as proper watering (one to two times per week).
  • Pseudomonas blight – symptoms include dry brown spots at leaf edges and margins. Remove affected leaves and water the plant less often.
  • Aphids – symptoms include yellowing of leaves, black sticky droppings on leaves or on soil under the plant, and curling or blistering of leaves. Use a pesticide spray that contains neem oil or an insecticide soap solution to get rid of them.
  • Fungus gnats – symptoms include small black flies that fly around the plant, and a soil surface that is covered in white webbing. To get rid of fungus gnats, repot the plant into fresh soil, and increase the frequency of watering.
  • Scale – symptoms include white or brown bumps on leaves or branches that may look like spots of sap. Use a pesticide spray that contains horticultural oil to get rid of scale insects.
  • Mites – symptoms include tiny red or black dots on leaves, webbing on the soil surface, and leaves with spots. Use a pesticide spray that contains horticultural oil to get rid of mites.

Protection from Bonsai Diseases and Pests

You can prevent diseases by giving your bonsai the right amount of sunlight, water, nutrients, humidity, air circulation, and drainage. Do not overwater or underwater your tree, and use the right soil mix. You can also protect your bonsai from pests by using a pesticide spray that contains neem oil or an insecticide soap solution.

If you fail to protect your bonsai from pests and diseases, it may eventually die. However, if you are vigilant and take steps to prevent these problems, your tree should stay healthy for many years.

Using a Soil Moisture Meter Before Planting a Bonsai Tree

All bonsai require watering and should not be allowed to dry out completely. This can be a problem for those who travel and beginner’s whose first attempts at growing their bonsai will fail if they forget to water them.

The best way around this is to use a soil moisture meter before planting a bonsai tree. By knowing when to water, beginners will have a better chance of success when growing their tree. The soil moisture meter can be used to check the amount of water needed in a plant’s root zone before watering it.

This is accomplished by inserting the probe into the soil and recording how much water needs to be added to increase the moisture level in the mix until it reaches the desired amount. A soil moisture meter is a valuable tool for the bonsai enthusiast and should be used on a regular basis.

A bonsai tree is a living plant and, like all living things, it needs water to survive. Bonsai enthusiasts have long battled with how to water their plants while they are away, or when they first start growing their trees. The answer may be a soil moisture meter.

Using a Finger Method to Check Soil Moisture Before Planting a Bonsai Tree

One of the easiest ways to check the moisture content of your soil is to use your finger.

To perform this test, simply dig your finger into the soil to a depth of approximately one inch. If the first several inches are dry, water the plant thoroughly until water drips through the drainage holes. Refer to this article on how long it will take for bonsai tree roots to become fully saturated with water .

A helpful rule-of-thumb is that the soil should be moist enough to hold together in a clump. If it crumbles easily or contains dry spots, then you should water your bonsai tree. Here are two articles on the best ways to water your indoor bonsai trees.

The post-soil moisture check is an important part of the watering process for your bonsai tree. It allows you to see how well the soil has absorbed the water and how long it will take for the plant to reach its desired level of moisture. Checking soil moisture regularly will help you make sure your bonsai tree stays healthy and looking its best.

Using the Chopstick Method to Check Soil Moisture Before Planting a Bonsai Tree

Soil moisture is an important factor to consider when planting a bonsai tree. A little too much or too little water can kill a bonsai. Another way to determine how much water the soil needs is to use the chopstick method.

To do this, insert a chopstick into the soil near the plant. If the chopstick is wet, the soil does not need watering. If the chopstick is dry, the soil needs watering.

Watering a bonsai can be tricky, so it’s important to pay attention to the plant’s condition and respond accordingly. Overwatering can kill a bonsai by causing root rot, while underwatering can lead to wilting and leaf scorching.

It’s also important to make sure the pot has drainage holes so excess water can escape. If the pot doesn’t have drainage holes, the soil can become waterlogged, which will also kill the plant.

The chopstick method is a quick and easy way to check soil moisture before planting a bonsai tree.

How to Know if Your Bonsai Lacks Watering and What Can You Do?

Watering is one of the key aspects of bonsai growing. Without the right watering techniques, your tree can quickly die. A good way to tell if your tree needs water is to check the soil. If the soil is dry, then it is time to water your tree. However, not all trees are created equal and some may need more water than others.

  • The key is to remember these different watering needs as bonsai trees come in a variety of species and all of them have different demands. When you learn how to grow bonsai trees, it’s important to know the basics about watering and fertilizing your tree.
  • Bonsai trees come in different varieties and each has its own watering needs. For example, bonsai trees that are evergreen typically don’t need to be watered as much since they tend to hold water throughout the year. That is not to say that these types of bonsai trees do not need water at all, but they will typically need less water than other types of trees.
  • Conversely, bonsai trees that are deciduous will need to be watered more frequently as they lose their leaves and moisture throughout the fall and winter. It is important to pay attention to your tree’s watering needs so you can provide the right amount of hydration at the right time.
  • One way to help ensure that your tree is getting the right amount of water is to use a moisture meter. This tool can be helpful in determining whether or not your tree needs water and how much it needs. Moisture meters are available at most garden stores and they are relatively inexpensive.
  • Another way to tell if your tree needs water is to take a deep look at the leaves. If you notice that the leaves are dull and have a wrinkled appearance, your tree could be in need of some extra moisture. This typically happens around mid-day when the temperature is warm and there isn’t much wind blowing.
  • The best way to water your bonsai trees is with a slow trickle of water. The key is to saturate the soil completely without over-watering it. One way to make sure you are giving your tree enough water is by carefully reading the instructions that come with your moisture meter. This will give you step-by-step instructions on how much water to apply and how often you need to do it.

If you follow your tree’s watering schedule and use a moisture meter, you should be able to provide the best environment for your bonsai tree. Over time, as you get to know your trees better, you can experiment with different watering schedules. That way, you will always ensure that your bonsai is getting enough water without overdoing it.

Is Over Watering a Bonsai Tree Fine?

It is essential to give your trees the proper attention they deserve. Watering can be done by looking at soil level or through clear plastic pots, but if you have had experience with this type of gardening it will not take long before knowing when there is enough water versus too much water. The wrong decision can lead to sick trees and even death.

  • Over watering a plant is one of the most common mistakes beginners make when it comes to growing bonsai trees. It’s not that hard to do; many people forget that these plants come from different places and they also have varying degrees of exposure to light, humidity and temperatures.
  • Over watering is the most common cause of root rot. This disease will start on the surface of the roots and then it will continue deeper into your plant’s structure, weakening some branches and making others to die.
  • There are two reasons why you should avoid over watering; one of them is that this habit makes your soil to become waterlogged, and the other is that it leads to anaerobic condition (oxygen deficiency), which will eventually kill your trees.
  • An easy test to see if you are watering too much is to lift up your pot’s soil. If it stays moist way below the surface and there is no dry layer of soil on top, then bring out the water hose and give it a good drink.
  • If you are only setting your bonsai tree on a small saucer, make sure to clean out the water from time to time because they might be sitting in stagnant water most of the time. Also make sure that this container is not too big or two small for your plant and that there is enough drainage.

Bonsai trees like to be wet, but they don’t want to sit in water. It is essential that you give them the right amount of water and never over water them. By following these simple steps, you can help keep your tree healthy and looking great for years to come.

Signs that Your Bonsai Tree is Overwatered and

If you’ve been growing bonsai trees, chances are that you know what overwatering is and the damage it can do even to your tree. Here are some signs you must look out for:

  1. The stems die – When the stems of your tree die, it means that the roots have been suffocated due to too much water.
  2. The leaves turn yellow – If your leaves are starting to turn yellow, it means that your tree is not getting enough sunlight. This can be a sign that the tree is being over-watered.
  3. The roots grow out of the pot – When the roots of your tree start growing out of the pot, it means that the soil is too wet and you’re probably overwatering your tree.
  4. The trunk looks unstable – If the trunk of your tree starts leaning on one side or another, then there is a possibility that it might fall off and break.
  5. The soil smells bad – If the soil in your pot smells bad, chances are you’re overwatering and it’s time to do some draining and go for a dry spell.
  6. The branches show to be weak and small – If the branches on your tree are weak and small, then you know that it’s time to be more careful with how much water you’re giving your plant. This is probably the first sign of overwatering.

These signs will tell you that you’re overwatering and killing your bonsai tree. If you think you’re doing everything right and still see these signs, then there is a more than likely chance that the soil of your pot might be holding too much water, or there’s no drainage hole in it.

What to Do if You Overwatered Your Bonsai Tree?

If you think you may have over watered your bonsai tree, there are a few things you can do to try and save it.

  1. First, try to let the soil dry out a bit before watering again.
  2. You can also check to see if the soil is still wet by sticking your finger in it. If the soil is wet, give it more time. It may take up to a week or two for the soil to dry out in some cases.
  3. If you want to speed up the drying process, try placing your bonsai tree in indirect sunlight and/or placing fans nearby.
  4. You can remove it from the container and gently shake off the excess water too.
  5. Cut off dry or yellow leaves to help the plant conserve energy.
  6. Rinse the tree and transfer to another container if the tree has a lot of water-logged soil.
  7. Use cold chamomile tea to water it sparingly.

These methods can help remove excess moisture from the leaves of your tree allowing them to recover.

Watering Your Bonsai Tree

Bonsai Tree’s Root Rots

The most common mistake made by first-time bonsai growers is watering their plants too much. Healthy trees can suffer from over-watering if their roots are not able to drain excess moisture quickly enough. Trees that have yellowing leaves or wilted ones usually mean there’s an issue with the soil and drainage of your bonsai pot, so it’s important you take care of this in order for them not become weak & unhealthy and eventually the roots rot.

Root rot is a serious issue that can affect plants and cause their death. It’s usually lethal, but there are some cases where it isn’t; in those situations you’ll need to take care of the plant yourself, but if it’s too late, you will have to remove the dead plant from its pot and replace it with a new one.

What Causes Bonsai Tree Root Rot?

Bonsai trees grow in small pots and as such, their root systems are very delicate and malleable. While the soil is moist, bonsai tree roots will continue to grow, but when the soil dries out, the growth will stop.

When you water your tree, the water should not completely fill up the pot and remain there; instead it should be slowly absorbed by the soil. If you’re watering your tree too often or if there’s not enough drainage in the pot, the roots will be constantly moist and this is what causes root rot.

It’s essential that you know how often your bonsai tree needs to have its pot watered, so it can actually dry out before being watered again. If you’re not sure how frequently it needs watering, check the guide on our blog where we talk more about how much water to give your tree.

Symptoms of Root Rot

The most common symptoms of root rot are brown or black leaves, wilting, and stunted growth. The leaves may also turn yellow if the problem is severe enough. If you see any of these signs, it’s important to take action right away and correct the issue with your bonsai tree’s soil.

Also, roots might become mushy and soft even before you see these other signs and if they do, you must take action asap to save your plant. You can usually test the roots by gently tugging on them and if they feel mushy at all, there’s definitely a problem with rot.

You’ll also notice that the soil in the pot will feel waterlogged and this is what you should avoid; if their roots stay too moist for too long, they’ll start to rot.

If your bonsai tree has root rot, it’s important to take care of it promptly or you could lose it. Usually, as mentioned above, there’s no coming back from root rot, but you can try to save your bonsai by following our guide on how to help prevent and treat it.

The Best Time to Water Your Bonsai Tree

Now that you know how to water your bonsai tree, it’s important to know when the best time to water it is. The best time to water your tree will vary depending on the type of tree, the climate, and the season. However, in general, you should water your tree early in the morning or late in the evening if we are talking about watering at that time of the day.

Peak of the Day’s Heat

The peak of the day’s heat is around mid-day. At this time, it is best to give your tree a break from the sun and watering. If you water your bonsai during this time, there is a chance that the water dries quickly in the hot sun, leading to a lack of water in the soil. This can cause the roots to dry out and die.

Watering in the Morning

Watering your tree in the morning is a good way to avoid the peak of the day’s heat. It also gives the tree plenty of time to absorb the water before the sun comes out and dries it up.

Watering in the Evening

Watering your tree in the evening is another good way to avoid the peak of the day’s heat. It also gives the tree plenty of time to absorb the water before and the moisture can remain all night until morning.

Tools for Watering a Bonsai Tree

Watering your bonsai tree is one of the most important daily, weekly and monthly tasks you will perform. How else are you going to keep it alive? The art of bonsai is actually not so easy as many people think, but keeping your tree healthy can be challenging at times.

However, with the proper tools for watering a bonsai tree, it will make your life a little bit easier. Let’s take a look at some of the most common tools you will need to water your bonsai properly.

Watering Can

One of the most important tools you will need is a watering can. This is what you will use to actually water your tree. It is important that you use a watering can rather than a garden hose because you will need to water your bonsai tree slowly and evenly. And, if you use a hose, you risk the chance of overwatering or washing away some of the soil.

Garden Hose

If you are in an area that has hard water or very high mineral content in your drinking water, you might want to consider getting a watering can with a built-in filtration system. This will allow you to use your own drinking water and be assured that you are not adding any minerals or chemicals into the potting mix of your bonsai tree.

Self Watering Bonsai Pot

If you would like to be able to leave your bonsai tree for a couple of days and not worry about it drying out, you might consider getting a self watering pot . This type of pot will use the moisture in the soil around the sides of the bonsai tree and slowly release it as the plant needs it. This is especially helpful if you work long hours and don’t have time to water your tree every day.

Watering Wand

If you have a large bonsai tree or a bonsai tree that is in a deep pot, you might want to consider using a watering wand . This is a long wand with a sprayer on the end that will help you reach the bottom of the pot without having to move the tree or get down on your hands and knees.

Watering Timer

If you are going to be using a watering can, it is helpful to have a watering timer . This will help you make sure that you are watering your tree for the correct amount of time. It is easy to forget how long you have been watering for and a timer will help to avoid over-watering or under-watering your tree.

Watering your bonsai tree is one of the most important aspects of keeping it healthy and looking beautiful. With the proper tools, you can make the job a lot easier and less stressful. So, be sure to have all of the tools listed above before you start watering your bonsai tree.

Watering Your Bonsai Tree


Bonsai is a Japanese term for a small plant grown in a container. These miniature trees are grown from seed or cuttings and can live many years with proper care and training.

The bonsai tree is not allowed to grow beyond its expected size, which means the branches and trunk of the tree will be trimmed regularly to keep the size in check.

As a new bonsai owner, there are a few things that you should keep an eye on to keep your tree healthy and vibrant.

Fertilizing, pruning and repotting are also other ways to care for your bonsai tree. Thus, having the proper tools to complete these tasks will make your life much easier.

There are many bonsai styles to choose from, so you should consider what type of tree or style you would like before starting your search for the perfect tree. Keeping bonsai trees healthy requires a lot of attention and effort on your part, but if this is something that appeals to you then it will be well worth the time and effort.
