Gardenia Bonsai Tree Care Sheet

General Description:

Gardenia Bonsai Trees from our wholesale nursery are some of the most popular choices for bonsai enthusiasts around the world and are native to the southern region of China and Japan. They are known for the unique contrast between the fragrant, white flowers and the dark green, waxy foliage that separate this specific tree from the rest. The fragrance produced from the flowers will slowly fill any area it occupies, making it a favored gift for friends or family on special occasions. They can be challenging to grow, but the reward gained from tending to their needs far outweighs the time you dedicate to them. Their cream colored flowers and pleasant scent will be sure to leave you happy, year after year.

Gardenia Bonsai Trees require strong amounts of sunlight, around 3 or 4 hours each day, so make sure it placed by a sunny window if you plan on keeping it inside.


Gardenia Bonsai Trees are native to tropical regions, and therefore need to be kept in an environment that is similar to the warm and humid conditions they are used to. We recommend that you keep your bonsai in temperatures between 68-74 degrees during the day, and about 60 degrees at night. If you can keep the tree inside in a sunny window and provide a humid environment, that usually works perfectly.


We recommend that you fertilize your Gardenia with an acidic fertilizer every four to six weeks from Spring to Fall to help promote healthy flower development and vigor.


We recommend that you water this bonsai regularly to keep the soil from drying out. As mentioned above, they require a lot of sunlight which can cause the soil to dry quickly, so frequent waterings are often needed. So, if you travel a lot, this tree might not be for you sadly. It is important to remember that just because the Gardenia loves humid environments with moist soil, it does not love swamps – so please ensure that you do not overwater. If you let the soil dry out completely or if you overwater, they can both be detrimental to the health of your bonsai.


The best time to trim and shape to your liking is after the flowering season. It is best to remove any dead leaves or wilted flowers after the flowering season, which will help keep the tree healthy and promote new growth. We recommend that you wire your tree just before Spring. Remember that shaping your tree is an art, and it is best to have a picture in your head of what you want the final product to be. Begin by bend the branches gradually by applying a small amount of pressure with your thumbs. Be careful not to break the branch and do not wrap the wire so tightly around the tree, as you do not want the wires to leave a mark on the bark.

Potential Insects or Pests:

A common pest with Gardenia Bonsai Trees is the aphid. Aphids are very small, and have a soft, tear-shaped body. They tend to cluster around any new growth as that is where they are able to suck out the nutrients needed for survival. Unfortunately, they can also carry viruses that can cause things like sooty mold (you don't want to mess with that), so you want to be sure to take of them as soon as possible! Mixed soap with warm water, and use the solution to gently wipe them away with a sponge. Even after the aphid is removed, be sure to wipe the area completely and then rinse with clean water to help prevent future attacks!

Another possible threat to the Gardenia is the mealy bug. They are a relatively common leaf pest that are white and usually form masses around the leaves of the tree. Carefully inspect your tree for them, as they try to hide along the protected areas of the plant, sometimes making the difficult to spot. Remove by hand and wipe the leaves clean with soapy water.


We recommend that you repot your Gardenia every 2 or 3 years during the early spring/late winter. You should replace the soil in the pot with one that is high in organic matter, and only about 10% of the roots should be pruned - so be careful not to prune too much off!

Additional Comments:

Gardenias are known to be extremely sensitive to being disturbed, as they do not like being touched or moved. While it may be difficult to resist the temptation to touch their waxy flower, it will cause them to brown and possibly fall off. Ensure that the Gardenia is in a sunny location, so it does not need to be moved often.
