Culture method of Gardenia jasminoides

Gardenia pot maintenance is very simple, follow the following steps to maintain it!

① chooses suitable basin soil

Gardenia likes acidic soil, and the suitable pH value is 5 to 6. Prepare suitable soil before planting. If the pH of the soil is not suitable, the maintenance after that is very troublesome.

Cultivation soil usually choose rotten leaf soil, peat soil plus half of the garden soil, do not use cinder, or directly buy gentleman orchid special soil, convenient and practical.

Rational fertilization of ②

Gardenia likes fertilizer, and rotten cake fertilizer is added to the soil as base fertilizer when planting.

Cake fertilizer and ferrous sulfate are used to make fertilizer and water in the growing season and irrigated once a week. Fully nutritious organic liquid fertilizer can also be used.

Topdressing for 1-2 times in the bud stage and watering the aqueous solution of potassium dihydrogen phosphate can make the flowers fat and fragrant.

The temperature is above 35 ℃ in summer and 15 ℃ in autumn, and fertilizer application is stopped.

③ scientific watering

Gardenia likes a moist environment. During the growing period from April to September, keep the basin soil moist, water dry and wet, and spray the leaves at night to maintain humidity. If the plant grows too fast, don't water it at night. Water it when the sun comes out in the morning.

In the northern alkali water area, when watering, the tap water will be watered after one day. For 3-5 days, pour a little citric acid solution to keep the leaves green.

④ basks in the sun more often

The growth of gardenia needs plenty of sunlight, if placed in the semi-shade for a long time, the flower branches are thin and slender. During maintenance, in addition to 7 stroke 8 and noon need shade and winter hibernation, the rest of the time can be maintained in the sun.

⑤ hibernates well in winter

Although gardenia is cold-tolerant, the root system of potted gardenia will be damaged after severe winter and recover slowly in spring. But in the room with heating, the temperature is higher, the light is insufficient, the plant growth slows down, and the flowering is later in the second year. The best way is to put the potted plant in a 5 ℃ environment to hibernate, or wrap the flowerpot with thermal insulation material and put it outside in the sunny leeward to survive the winter.

⑥ pruning properly

When the trunk of Gardenia jasminoides grows to 20 cm, hit the top, leaving 3-4 branches to promote branches. After flowering every year, prune lightly and cut off weak and diseased branches. But gardenia can not be cut short in spring, otherwise it will be difficult to blossom in that year. (recommended by editor: how to trim gardenia?)

⑦ change basin soil at the right time

Gardenia is full of vitality, and the seedlings grow from a few centimeters to dozens of centimeters, so the pot should be changed according to the size of the plant. When the branch length of the plant is 2 to 3 times the diameter of the flowerpot, the pot needs to be changed. When changing the basin, you should trim the old roots in time, change half of the soil, pour water through, put it in the semi-shade for a week, grow new buds and move to the sun.

Matters needing attention in Gardenia Culture

① pest control

Gardenia is more prone to chlorosis, leaf spot and scale insects, especially in flowering summer, the weather is hot and humid, fungal infection leads to diseases and insect pests. After the discovery, spray disinfection in time, isolate from other plants, and avoid infection.

② soil acidification

Gardenia likes fat, but is afraid of thick fat. During the growing period, the rotten cake fertilizer and water should be applied every half a month, and the concentration should be low, so as not to burn roots and affect the growth of flower buds. At the same time, it is necessary to pay attention to acidifying the soil in time. Most of the water in the home is alkaline, long-term watering will lead to soil alkalization, timely irrigation of ferrous sulfate solution, change the acidity and basicity of the soil, can promote plant growth.
