If you are looking for the ultimate Gardenia Bonsai care guide, this is it. Gardenias are perfect for adding color and beauty to your home. They are also very easy to care for, making them an excellent choice for anyone who is looking for a low-maintenance plant that will last a long time.

However, if you do not provide the proper care, they can become sickly and die within just a few months of purchase. This article will go over the basics of gardenia bonsai care so that they can live out their full life cycle with you!

What is a Gardenia Bonsai?

A gardenia bonsai is a small tree that has been trained to grow in a pot. They are native to Africa and Asia and can be found in a variety of colors including white, pink, and yellow. Gardenias make excellent indoor plants because they require very little maintenance and thrive in humid environments.

How to Care for Gardenia Bonsais


Gardenias need to be watered regularly, but you should avoid over-watering them. The best way to determine if your gardenia needs water is to check the soil. If the top inch of soil is dry, then it is time to water your plant.

Water Temperature: Gardenias prefer lukewarm water, so try not to use cold tap water when you are watering your plant.


Gardenias grow best in indirect sunlight, so they should be placed near a window that gets some sun but is not directly facing the window. If there is no good place for your gardenia to get natural light, then artificial lighting will work fine as well. However, do not use fluorescent light, as this can cause your plant to grow leggy.


Gardenias need to be fertilized once a month with a balanced fertilizer. You can find this type of fertilizer at any garden center or home improvement store.

When you are fertilizing your gardenia bonsai, it is important to make sure that the fertilizer is evenly distributed throughout the soil. One way to do this is to add the fertilizer to a watering can and water your plant with it. You can also use a foliar sprayer to apply the fertilizer directly onto the leaves of your plant. This is a good way to get the fertilizer into the soil and help your plant absorb it more easily.


Gardenias need to be pruned regularly to keep them healthy and looking their best. You can prune your gardenia bonsai by pinching off the new growth with your fingers or using sharp scissors.

Pruning Tips:

  • Pruning should be done in the early morning or evening when the plant is not as active
  • Avoid pruning during hot weather, as this can cause your plant to wilt
  • Make sure that you are pruning the correct branch by looking for new growth at the tips of branches
  • Remove any dead or wilted leaves from your plant
  • Be careful not to damage the bark when pruning

Gardenia bonsais should be repotted every two to three years. You can tell it is time to repot your plant when the roots start to grow out of the pot and into the air. When you are repotting your gardenia, make sure to use a pot that is one size larger than the one you are currently using. Also, do not be afraid to use a container that is much larger than what your plant originally came in. This will help prevent the roots from growing out of the bottom and onto the floor!

Repotting Tips:

  • Use well-draining soil when planting your bonsai tree
  • Water your gardenia bonsai immediately after you have finished repotting it
  • Using a bonsai pot: If your gardenia is still in the nursery pot, then place some wire mesh on top of the soil and pull up gently to remove your plant from its old container. Be careful not to damage the roots when doing this! Next, wash out any dirt that might still be on the roots and place your plant in a new pot.
  • Using an alternative container: If you are using a different type of container, then it is important to make sure that there is good drainage. You can do this by placing rocks or broken pieces of pots at the bottom before adding soil and planting your tree. Make sure that there is enough room for the roots to spread out and remain moist; if not, you might need a larger container!


Gardenia bonsais can be propagated by taking cuttings from new growth. To do this, take a cutting that is about four inches long and remove the leaves from the bottom two inches of the stem. Then, insert the cutting’s end into rooting hormone and potting soil. You can then place the cutting in a warm, sunny place. After your cuttings have been growing for about six weeks, you should start to see some roots forming!

Be careful not to leave the leaves on the bottom of your stem too long when taking this type of cutting as they can rot and cause problems with growth. You also need to make sure that the rooting hormone is fresh and has not expired.

Pests and Diseases

Gardenias are susceptible to several pests and diseases. The most common ones are aphids, scale insects, and mealybugs. These pests can be treated by using insecticidal soap or horticultural oil.

If you think that your gardenia is infected with a disease, then take a sample of the leaves to your local nursery for identification. Be sure to treat the plant immediately once you have identified what type of disease it has!
