1, water and fertilizer
The soil where Smilax China grows should be kept moist. Generally, water once every 1 ~ 2 days in spring and once every day in summer, and control the water quantity to avoid water accumulation. Smiling flowers that need nutrients should be fertilized once in the growing period 10 ~ 15 days, but not in the flowering period, so as not to affect their flowering, and stop fertilizing after 10 days.
2. Smiling flowers with suitable light and temperature should not be exposed to strong light, and should be shaded in summer, and can maintain sufficient sunshine in winter. Usually, the growth temperature of smiley face flowers should be controlled at about 20℃, and the temperature in winter should be stabilized at 5 ~ 15℃, so that the nutrients of smiley face flowers will not be consumed, and they can survive the winter and grow vigorously in the coming year.
3, drainage soil
How to cultivate Smilax China with fleshy roots and provide it with breathable and loose drainage soil? Generally, garden soil, humus soil, river sand and decomposed manure can be mixed in the ratio of 3:4: 1:2 to prepare the required soil, or ferrous sulfate can be added to make it acidic.
4. Pruning insect-resistant smiley faces is generally not pruned. It is mainly shaping and pruning after flowering, cutting off weak branches, dense branches and long branches that consume nutrients, so as to maintain a ventilated and transparent growth environment. We must also do a good job in pest control, remove pests with brushes in time, and spray drugs to sterilize and kill insects.
5. Cutting
Cutting propagation of smiley face flowers is mostly carried out during maintenance, and pruning is often carried out from July to September. Select 15cm long lignified branches with 3-6 leaves, apply rooting powder after wound treatment, cut them into prepared sand, and water them for shade. After 2 ~ 3 months, the branches will take root.
