Hibiscus efficacy: clearing heat and promoting diuresis, cooling blood and detoxifying, moistening lung and relieving cough;

Hibiscus can be propagated by sowing, cutting and grafting. Cuttings can be combined with pruning and shaping from mid-March to early April. Cuttings should be strong wooden branches, with a length of 10 ~ 12 cm. They should be planted in the open air in red soil or sandy soil to ensure soil moisture, but the survival rate is low.

It is best to cut in a seedbed with plastic film to keep moisture. It is easy to survive in the temperature range of 65438 07℃ to 20℃. Hibiscus has strong adaptability, rough growth and easy cultivation and management.

Extended data:

The common pests of hibiscus mainly include aphids, leaf rollers, inchworms, stickleback moths, etc. The control methods are as follows:

1. Aphids: When aphids first hatch in spring, spraying 80% dimethoate emulsion for 200 times or spraying 40% dimethoate for 2000 times can kill branch aphids. For aphids that have formed galls or produced on trees in autumn, the concentration of pesticides should be appropriately increased.

2. Leaf roller moth: When the larvae are in the damage state of leaf roller moth before hatching or landing, spray 50% phoxim 1000 times and 90% trichlorfon 1000 times.

3. inchworm: 90% trichlorfon or 40% dimethoate 1000 times solution is sprayed in larval stage to kill larvae and protect the release of parasitic bees.
