Cultivation techniques of marigold

Sowing in common use, cuttage propagation, sowing in autumn in September, and germination in about 7- 10 days, with neat germination. Autumn meristem is not as good as spring meristem. Flowers bloom early and flourish. Before flowering, shoot cuttings at the top, with a length of 5-7 cm, and take root after cutting10-1.

Leaf spot and stem rot are common hazards, and 600 times of 65% zineb wettable powder can be sprayed. Insect pests are harmful to bugs and liriomyza sativae, and they are sprayed with 500 times of 25% carbaryl wettable powder.

The temperature at seedling stage should not be too high, otherwise it is easy to grow white, and seedlings should be thinned in time. Fertilize l times a month during the growing period, and control the dosage. Excessive fertilization will delay flowering. Cutting off the aboveground parts after flowering is beneficial to the germination of basal leaves.
