Marigolds come in a rich variety of colors, so when are they generally sown?

Marigold, also known as yellow chrysanthemum and satin flower, generally grows on mountains at higher altitudes. When it blooms, its flowers are brilliantly colored and rich, as gorgeous as a peacock spreading its tail, which is why it is called marigold. The common colors of marigold flowers are red, yellow, orange and so on. It can be harvested in summer and autumn and has extremely high medicinal value. At present, marigold has gradually become a main flower for flower beds and courtyards. Sowhen are the colorful marigolds generally sown?

1. When are marigolds generally sown?

There are many varieties of marigold, and different marigolds have different planting times. The spring-autumn sowing series of marigold can generally be sown from September to February in southern regions where the daytime temperature is above 15 degrees, while the Jenny series is most suitable for summer sowing from March to August. There are also some other marigolds whose sowing times differ, so you can ask the merchant when purchasing seeds.

2. Notes on marigold care

1. Key points for watering

Marigold has no great requirements for watering. As long as the soil becomes dry, it can be watered, and it can be watered thoroughly.

2. Applying fertilizer

During the growing period, marigold can simply be given some water-soluble fertilizer as appropriate, because some artificial medium fertilizer can be added as a base fertilizer when preparing the soil for marigold. Therefore, during its growing period, water-soluble fertilizer can be applied once every 7-10 days. In winter, fertilization can be reduced.

3. Key points for pruning

Marigold cuttings can take root and be potted 1 week after cutting. After the autumn cool arrives, they can grow rapidly into shape and continuously produce bright flowers.

4. Key points for propagation

Marigold can be propagated by both sowing and cuttings. Sowing is carried out from November to March. Those sown in winter and spring bloom from March to May. Sowing can be done directly in the courtyard or in pots. For pot cultivation, about 1 month after sowing, the seedlings can be dug up and potted for final planting. For cutting propagation, from June to August, tender branches about 10 cm long can be cut and inserted directly into the courtyard, covered with shade, and they will grow quickly. They can also be inserted directly into flower pots. Those cut in summer and autumn bloom from August to December. Whether inserted in the ground or in a cutting bed (pot), cuttings can survive.

As flowers for welcoming “May Day” and celebrating “National Day”, sow in a greenhouse or indoors in mid-February. After one transplanting, plant them temporarily in flower pots with a diameter of 20 cm. After the late frost, remove them from the boxes and plant them in the open ground.

5. Pest and disease control

Marigold mainly suffers from root rot at the seedling stage, which can be controlled by drenching the roots with an 800-fold solution of thiophanate-methyl.

The main insect pest is red spider mite, which can be controlled by spraying a 1500-fold solution of dimethoate.

Common diseases include brown spot and powdery mildew, which are fungal diseases. A good site should be chosen for cultivation, and attention should be paid to drainage and irrigation, removing diseased plants and diseased leaves, burning residual branches, and timely spraying fungicides such as rust-powder-ning. The main insect pest is red spider mite. Cultivation management can be strengthened, and in the early stage of pest occurrence, a 500--600-fold spray of 20{bf} dicofol emulsifiable concentrate can be used for control.
