Identify my gardenia augusta

Gardenia is a genus of 200 species of evergreen trees and shrubs from savannah or tropical forests. The leaves are opposite, arranged in whorls, thick, lustrous. The flowers are at the top of the branches, very fragrant, often white, shaped in tubes or funnels.

Plant my gardenia augusta

As a savannah and rainforest plant, your gardenia will appreciate being planted in a draining mix. Indoor potting soil is usually mixed with heather earth. Choose a tank of at least 10 liters and put clay balls at the bottom. Soak the root ball for a moment then place your gardenia in the tank. Add your soil-heath mix to cover all the roots. If necessary, lift the plant to adjust the planting depth. Avoid watering with tap water if it is very calcareous, water with rainwater or filtered water. Place your gardenia in the dim light, not too close to a radiator.

Water my gardenia augusta

Gardenia does not like excessive moisture, but it often needs to be watered. As soon as the top of the soil becomes dry, water until the soil is moisten. During the growth period (spring, summer), the watering should be regular - about twice a week - but measured in order not to drown the roots. In the fall, gradually space the waterings until the winter when a simple input of water twice a month should suffice.
