So when will gardenia blossom? How many times a year do you bloom? What's the best way to raise it in winter?

When will the gardenia blossom

The flowering period of Zhizhi is from May to June, and the fruit ripening period is from November to December. So gardenia blossoms twice a year.

Management of Zhizhihua

1 Gardenia likes fertilizer, it is appropriate to apply balanced and peaceful organic fertilizer, soy bean cake, sesame sauce residue, peanut bran, etc., after fermentation and ripening, it can be acidic fertilizer, but only thin fertilizer can be applied frequently, and avoid thick fertilizer and raw fertilizer. Rich fertilizer can easily lead to root name damage and even rot. The reaction after rotting the root is on the leaf.

Gardenia likes flowers in a humid environment, but if it is watered too much, too much water in the pot soil will lead to less air in the soil, damage to the roots, and blackening of leaves and loss of leaves. Therefore, special care should be taken in the maintenance process. In addition, Gardenia jasminoides is a semi-negative flower, temporarily put indoors, can not see the sun for a long time, can not carry out photosynthesis, the leaves will be yellow. So in spring, gardenia must be maintained in sunny outdoors as much as possible.

(3) the flower with flower bone flower is the most vigorous time of physiological activity, not only to meet the needs of physiological growth, but also to meet the needs of reproductive growth, which need to supply a large amount of nutrients to the leaves and flowers through the root system. At this time, if you suddenly change the conservation environment, or change the pot to move the soil, the physiological balance will be broken, leaves and buds can not quickly adapt to the new environment or get due nutrients. There will be falling leaves, falling buds, and even death.

Gardenia also particularly needs iron moisture, iron deficiency will get chlorosis. Some leaves under the root feet are a little yellow, not yellowing, chlorosis first appears on the new leaves, begins to show light yellow or yellowish white, the veins are still green, slowly the leaves atrophy, and even fall off and die. Therefore, gardenia must use ventilated, breathable acid soil, and 0.2% Mel 0.5% ferrous sulfate solution should be sprayed frequently to prevent yellowing.

Magnesium deficiency can also cause yellowing of leaves, characterized by the yellowing of old leaves and the development of new leaves, the veins of leaves are still green, and when they are serious, the leaves fall off and die. For this situation, 0.7% Mo 0.8% boron and magnesium fertilizer can be sprayed to prevent and control.

(5) excessive light will also cause leaves to yellowing or even fall off. Gardenia like semi-shade, afraid of strong light exposure, require about 50% shade, summer can only direct sunlight in the morning and evening.

How to raise gardenia in winter

I. temperature control

Gardenia in winter indoor culture, should pay attention to temperature regulation, gardenia cold tolerance is relatively strong, only when the temperature below minus 12 degrees will appear death and leaf shedding.

Gardenia in winter will be in a semi-dormant state, so after winter gardenia leaves fall or even stop growing, do not panic, this is a normal phenomenon. As long as the indoor temperature is kept between 3-5 ℃, too high temperature is not conducive to the safety of gardenia through the winter.
