Trees Features:
Gardenia Bonsai are evergreen shrubs with luxurious white or cream colored flowers that are either solitary or form in small attractive clusters. Many species of Gardenia have a very strong scent which is delightful to most but can have adverse effects on people suffering from asthma or allergies.
Temperature:
Gardenia Bonsai are a tropical plant, and as such require that their environment is warm and humid. During the day, Gardenia Bonsai will prefer a temperature of 68-74 degrees, with a low of 60 degrees at night. In areas with a lot of sun and dry heat or cold temperatures it is advisable to have your Gardenia Bonsai indoors, but with arrangements to ensure that the plant is exposed to good amount of sunlight.
Lighting:
Gardenia Bonsai can be kept outdoors as it should be exposed to the sunlight for at least 3 to 4 hours each day and when kept indoors it should be placed at a place adequately exposed to sunlight, such as a southern facing window.

It is preferable to keep the Gardenia Bonsai watered regularly to ensure that the soil does not get dry. Since it should be exposed to sun for at least half of the day it will require more frequent watering compared to some other bonsai varieties, which is an important factor to consider for anyone who travels away from home regularly. Being a tropical plant means that they need to live in moist, well drained soil ensuring that the soil never dries out because that would be detrimental to the Bonsai, leading to death, or rotting of buds. Be sure to not over-water…liking humid conditions does not mean they thrive in swamps. Dropping of buds on Gardenia Bonsai can occur with over-watering or dry conditions. Gardenias like to be kept evenly moist, but do not do well when misted as damp leaves can encourage fungal growth. Keeping your Gardenia Bonsai pot elevated on pebbles will ensure that the roots do not sit in water which will prevent root rot.
Fertilizing:
Gardenia Bonsai are acid loving plants and appreciate being fertilized with a quality acid fertilizer every 4-6 weeks beginning in the spring after the new leaves begin to firm, off continuing well into the fall and early winter.
Pruning / Training:
Pruning of Gardenia Bonsai must be carried out to give the plant a proper shape and size. It is advisable to carry the pruning exercise after it the flowering season has ended.
Ensure removal of all the dead leaves and flowers to promote new growth of the Gardenia bonsai. Wiring should be carried out during late winter or spring. Decide on the position or shape a branch is to occupy before bending it. Slowly apply a small amount of pressure with the thumbs, bending gradually, repeating in several locations rather than risk too much in one place. Repeat the process every few days. Be sensitive to any increase or decrease in resistance; wiring should be carried out with attention and patience, ensuring that the wire on the bark is not tightened so hard that the wire leaves marks on it or breaks the branches under the stress of careless wiring. The Gardenia Bonsai is beautifully suited to a variety of training styles such as the classic umbrella style or the ever graceful semi cascade style.
Insects / Pests:
If you discover that your Bonsai has encountered the stress of bugs or diseases, isolate the plant immediately to prevent spreading to other plants and Bonsai. One of the biggest Gardenia Bonsai leaf pests is the aphid. These pesky bugs have soft little bodies and are tear-shaped. They cluster usually below leaves and around new growth on the gardenia plant. The aphids actually suck the fluid from the plant, which is why they like the new growth because it tends to be more lush and moist. Because they are a sucker, these garden insects can spread viruses as well. An effective remedy to take control of aphids is to make a diluted soap and water solution. Spray the leaves until the solution runs off, gently wipe leaves with a soft sponge, rinsing after each pass to ensure aphid removal. Take a final rinse with pure water and keep your eyes peeled in the days following for further attacks!
Another gardenia pest is the mealy bug. Mealy bugs are the most common gardenia leaf pests you will see. They are white and found in masses along the leaves of the gardenia. They tend to hide themselves along protected areas of the plant. A good home remedy for dealing with mealy bugs is wipe them off by hand and spray your Bonsai with Neem Oil.

Other than gardenia bugs, there are a few other gardenia diseases to consider. One of the worst gardenia diseases is sooty mold. Sooty mold is a foliage disease that it turns the leaves of the gardenia black. It doesn’t injure the plant, but it does prevent sunlight from getting to the plant via the leaves, so the plant doesn’t perform as much photosynthesis inhibiting growth. Sooty mold thrives on the honey dew created by gardenia bugs like aphids. If you control the aphids, you will also be able to control sooty mold.
Propagation:
Rooting a gardenia cutting is very easy. Just cut off about a small 6 inch piece from a healthy mother plant and put it in a jar of water. Very quickly you will begin to see the appearance of roots. When there are plenty of roots, you can put your new plant in a good rich organic soil for acid loving plants keeping it moist to ensure continued growth and health.
Repotting:
Repotting your Gardenia Bonsai should be carried out every 2 years during the late winter, or during the spring season. When repotting, remember to prune the roots carefully—too much root pruning would be detrimental to the plant; hence only about 10% of the roots should be pruned. The soil used during the repotting process should have a high content of organic matter.
Additional Comments:
Caring for a Gardenia Bonsai is not easy but the spectacular results are certainly worth the effort. With abundant sweet smelling blooms and attractive year round foliage, you can be sure with proper care and sensitivity, you will be able to keep your Gardenia Bonsai as a show stopping sensation for years to come. Keep in mind that Gardenias are extremely sensitive to being moved or touched because they do not like to be disturbed, and changing your Gardenia Bonsais location may result in the gardenia buds falling off. Try to keep your Gardenia Bonsai in one ideal, sunny location, moving as little as possible and resist the temptation to touch the waxy flowers as this will cause browning to the petals. As one more point of interest, Bonsai, like people and animals, are sensitive to the effects of second hand smoke and will be healthier in a smoke free environment.
