Second, gardenia is pregnant to form flower buds in April, so between April and May, in addition to cutting off individual jumbled branches and leaves, it should generally focus on protecting buds; when flowering in June, residual flowers should be cut off in time to promote the emergence of new shoots, and when the new shoots grow to 2-3 nodes, carry out the first coring and properly wipe off part of the axillary buds; in August, you can get beautiful tree-shaped plants by coring the second stubble branches and cultivating the crown. Gardenia requires that the acid soil of soil pH5-6 grows well, and in the neutral or alkaline soil of the north, it should be irrigated with alum fertilizer or foliar spraying ferrous sulfate solution.

Culture methods:

1. Choose suitable basin soil.

Gardenia, like acid soil, prepare suitable soil before planting. If the pH of the soil is not suitable, the maintenance after that will be troublesome. Cultivation soil, usually choose rotten leaf soil, peat soil, add half of the garden soil, do not use cinder, or directly buy gentleman orchid, special soil, convenient and practical.

2. Rational fertilization

Gardenia likes fertilizer, when planting in the soil, add maturity, cake fertilizer as base fertilizer.

During the growing season, cake fertilizer and ferrous sulfate were used to make fertilizer and water, which were irrigated once a week. Total nutrition and organic liquid fertilizer can also be used. It 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, like wet, humid environment. During the growing period from April to September, keep the basin soil moist, watering dry and wet, at night, spray to wet the leaves to maintain humidity. If the plant grows too fast, don't water it at night. You can water it when the sun comes out in the morning.

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

4. Bask in the sun

Gardenia, the growth needs sufficient sunlight, if put in the semi-shade for a long time, the flower branches are thin and slender. Maintenance, in addition to 7 stroke 8 and noon, need shade, as well as winter hibernation, other time, can be maintained in the sun.

5. Good dormancy in winter

Gardenia, although hardy, but potted gardenia, after the severe winter, the root system will be damaged, slow recovery in spring. But put in the room with heating, the temperature is higher, the light is insufficient, the plant growth slows down, and the next year blossoms later. The best way is to put the potted plant in a 5 ℃ environment and hibernate, or wrap the flowerpot with heat preservation material, put it outdoors and spend the winter in the sunny leeward.

6. Proper pruning

Gardenia, after blooming every year, prune lightly to cut off weak and diseased branches. But gardenia in spring, do not truncate the top, otherwise it is difficult to blossom.

7. Change the basin soil at the right time

Gardenia, vitality, seedlings from a few centimeters long, to dozens of centimeters, so, according to the plant size, change the pot. When the branches of the plant are long, 2-3 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 culture:

Pest control:

Gardenia is relatively easy to appear, 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 discovery, timely spray disinfection, with other plants, isolation, to avoid infection.

Soil acidification:

Gardenia likes fat, but is afraid of thick fat. Growth period, every half a month, apply rotten cake fertilizer and water, 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, and long-term watering will lead to soil alkalization, change the acidity and basicity of the soil, and promote plant growth.
