When the temperature is above 35 ℃ in summer and 15 ℃ in autumn, fertilization should be stopped.
3 scientific watering
Gardenia likes humid environment. 4~9 month growth period, keep basin soil moist, watering see dry to see wet, evening spray can leaf wet, in order to maintain humidity. If the plants grow too fast, don't water them at night. Water them when the sun comes out in the morning.
In the northern alkali water area, when watering, the tap water should be placed for one day to irrigate. 3 ~ 5 days, pouring a little citric acid solution, can keep the leaves green.
The growth of Gardenia needs sufficient sunshine. If it is placed in the shade for a long time, the branches are thin and slender. In the maintenance, except for 7 / 8 and midday shading and winter hibernation, other time can be maintained in the sun.
5 good dormancy in winter
Although Gardenia jasminoides is hardy, the roots of potted Gardenia can be damaged after severe winter, and the recovery is slow in spring. However, the temperature is higher and the light is insufficient in the room with heating, so the plant growth slows down, and the next year it blooms later. The best way is to put the potted plants in the environment of 5 ℃ to hibernate, or wrap the flowerpots with thermal insulation materials and put them in the outdoor sunny and leeward place for winter.
6 proper pruning
When the main stem of Gardenia jasminoides grows to 20 cm, the top is removed and 3-4 branches are left to promote the branches. After flowering each year, light pruning, cutting off the weak and diseased branches. But Gardenia can not be cut off in spring, otherwise it is difficult to blossom in the same year.
Change basin soil timely
The vitality of Gardenia jasminoides is exuberant, the seedling grows from a few centimeters to dozens of centimeters, so it is necessary to change the basin according to the size of the plant. When the branch length of the plant is 2 ~ 3 times of the diameter of the flowerpot, it is necessary to change the pot. When changing pots, the old roots should be pruned in time, half of the soil should be changed, and the water should be watered, and placed in the half shade for a week. After the new buds grow, they should be moved to the sun.
