Gardenia breeding method watering, fertilization, soil, light, pruning. Note: Replace the potting soil for gardenia every 1-2 years to avoid its poor growth.
one, breeding method
1, watering
Gardenia like wet and humid environment, in the growth stage of April to September, watering to keep the potting soil moist. Give gardenia watering, need to water in season. In the spring about 3 days watering times. In summer, water once a day in the morning or evening. In the fall about 2 to 3 times a week watering. In winter, control watering and use warm water when the soil is dry.
2, fertilization
Planting and potting, the soil can be added to the appropriate amount of cake fertilizer or bone meal as a base fertilizer. In the growth period, fertilizer can be used organic liquid fertilizer, diluted and then used, about 1 time per month.
Spring will grow buds, fertilization can be based on phosphorus and potassium elements of potassium phosphate fertilizer, about 1 time per week, can promote the differentiation of flower buds, until the formation of buds to stop fertilizer. No fertilizer during flowering, you can use 1 time of potassium dihydrogen phosphate after the flowering period, which is helpful for the later growth.
3, soil
Soil can be made with 4 parts peat soil + 1 part perlite + 1 part + 1 part pine needle soil mix, soil nutrient rich, moisture retention and water retention of strong, loose and breathable, but also slightly acidic, is very suitable for gardenia as the cultivation of soil.
4, light
Gardenia likes light, is typical strong positive flowers, spring, fall and winter three seasons need to get enough sun, so that the flowering will be bigger and more fragrant. Summer temperature is high, light intensity is big, need to do a good job of shading measures, avoid leaf yellowing.
5, pruning
The main pruning time of gardenia is in the growing period of May~July and the dormant period of December or so, the two phases also don't need to over prune. In the more vigorous growth time, can be too long, too dense, poor growth of branches and leaves cut off, looks very messy, and very affect the growth and ornamental branches and leaves should also be appropriate pruning.
After the plant grows flower buds, you need to remove the poorly grown buds and keep the robust ones to ensure the quality of flowering, so that the plant can bloom big and full.
Two, precautions
1, don't put the gardenia in direct light exposure for a long time, the leaves will be sunburned. Also don't keep in the dark environment for a long time, so that the leaves can't photosynthesize to form chlorophyll, will appear yellow leaves, leaf drop and so on.
2, gardenia cold hardiness is poor, winter to control the temperature above 10 ℃, below 5 ℃ temperature will appear frostbite, lead to yellow leaves and fall.
