1. Like the tide, dampness and more yang

Gardenia likes light and can grow in semi-shade for a long time, but it must maintain 60% light throughout the day in order to meet its growth needs.

2. Choose acidic basin soil.

The suitable pH value is 5 to 6. Cultivation soil can choose rotten leaf soil, peat soil or retting sawdust plus half of the garden soil, do not use old wall soil and cinder.

3. Watering frequently

The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If the growth is too prosperous and the internodes are longer, they will not be watered in the evening and will be watered again when the sun comes out in the morning.

4. Fertilizing frequently

3% rotten cake fertilizer can be added to the culture soil as base fertilizer. The alum fertilizer made from cake fertilizer and ferrous sulfate retting was watered once a week during the growing season, 0.1% potassium dihydrogen phosphate solution was irrigated once or twice in the bud period, and the fertilizer was stopped when the temperature was above 35 ℃ in summer and below 15 ℃ in autumn.

5. Change the basin soil at the right time

Family potted plants when the crown width reaches about 28 cm, change the pot soil, if it is to change the pot, then even the soil should be planted into the new pot. It is better to change soil in March in spring.

6. Proper pruning

Three main branches are selected according to the shape of the tree, and other branches sprouting from the roots should be cut off at any time. Remember that gardenia can not be cut short in spring, otherwise it will not blossom in that year.

7. Good dormancy in winter

The root system of Gardenia jasminoides will be damaged after the severe winter in the north and will not recover until spring. Therefore, it is necessary to wrap the potted flowers with styrofoam and other thermal insulation materials, protect the roots, and put them in the leeward and sunny place to survive the winter, which can recover quickly and bloom early in spring.

The yellowing of Gardenia jasminoides leaves is common, which is caused by a variety of reasons, so different measures should be taken to control it.

8. Iron deficiency

When the young leaves are deficient in iron, the veins of the young leaves lose green and yellowing, which will seriously yellowed the whole leaves, and even scorched leaves and branches wither, resulting in plant death. To this kind of situation, can spray 0.2% Mel 0.5% ferrous sulfate solution to prevent and cure.

9. Magnesium deficiency

The chlorosis caused by magnesium deficiency gradually developed from the old leaves to the new leaves, the veins were still green, and when the leaves were serious, the leaves fell off and died. For this situation, 0.7% Mel 0.8% boron and magnesium fertilizer can be sprayed to prevent and control. Excessive watering, freezing and so on will also cause the phenomenon of yellow leaves, so special attention should be paid to it in the process of maintenance.
