How to cultivate potted gardenia and grasp 7 key points to make gardenia bloom brilliantly

White gardenia, although no makeup, but white quiet feeling, so that many friends love gardenia from now on. So, how to grow gardenias in pots? Put a pot of beautiful and fragrant gardenia at home, which is a good choice.

Gardenia likes sunny environment, proper shade can grow normally. In a shaded environment, the leaves are dark green, but the flowering is poor, shading is not recommended. Gardenia likes a relatively humid environment, heat-resistant and slightly cold-resistant (minimum-3 ℃). Like fertile soil, the soil is too poor to lead to premature aging of the plant. The branch of Gardenia jasminoides has strong germination ability, resistant to pruning, and timely pruning is beneficial to branch and plant regeneration. If the environment in your home can meet the above points, it is not a problem to feed gardenia. However, potted gardenias still need to grasp the following seven key points.

1. Choose 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.

2. Rational fertilization

Gardenia likes to be fertilized, but it needs reasonable fertilization:

When planting, add rotten cake fertilizer to the soil as base fertilizer.

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

4. Bask in the sun

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. Good dormancy 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. Proper pruning

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.

7. Change the basin soil at the right time

The vitality of Gardenia jasminoides is exuberant, and the seedlings grow from a few meters to dozens of meters, 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.

The maintenance of plants pays attention to a "degree": too much is not as good as it is. Therefore, planting gardenia also needs to grasp the requirements of fertilizer, water, temperature, humidity and soil, no more or less is the most appropriate.
