How and when to plant peacock grass

Marigold is a highly ornamental flower with colorful colors, long-lasting flowering, and simple cultivation. It has strong ornamental value and certain horticultural uses and is deeply loved by gardening enthusiasts. Understanding the planting method and best planting time of marigold is crucial to the successful cultivation and appreciation of this beautiful flower. Let's talk about the planting method and time of marigold.

1. Planting time

The best time to plant cosmos is from April to May in spring or from August to October in autumn. The temperature during these two periods is suitable, which is conducive to seed germination and seedling growth. In warm areas, cosmos can also be planted in other seasons, but attention should be paid to the control of temperature and humidity.

2. Soil Preparation

The soil requirements of cosmos are not strict, but loose, fertile and well-drained soil is preferred. Before planting, the soil should be plowed and an appropriate amount of decomposed organic fertilizer or compound fertilizer should be applied to improve soil fertility. Before sowing, the soil should be disinfected to reduce the occurrence of diseases and pests.

3. Sowing Method

Maidenhair is usually sown by seeds. Before sowing, the seeds can be soaked in warm water for 24 hours to promote germination. When sowing, spread the seeds evenly on the soil surface and cover them with a thin layer of soil about 1-2 times the diameter of the seeds. After sowing, keep the soil moist and avoid waterlogging.

4. Seedling Management

The suitable temperature for cosmos seeds to germinate is 22℃ to 24℃, and the germination time is about 5-8 days. During the seedling stage, appropriate temperature and humidity should be maintained to avoid excessive moisture or dryness. When the seedlings grow to 2-3 pairs of true leaves, they can be thinned out and transplanted, maintaining appropriate plant spacing.

5. Maintenance and management

Mauve loves light and should be given sufficient light during its growth period. During high temperatures in summer, appropriate shade is needed to avoid direct sunlight. Marigold is not cold-resistant and the temperature should be kept above 5℃ in winter. When watering, water thoroughly after the soil is slightly dry to avoid water accumulation. In terms of fertilization, apply fertilizer every 7-10 days during the growth period of cosmos, and reduce fertilization in winter.

VI. Pest and disease control

Marigold has fewer diseases and pests, but it may encounter infestations by moth larvae in greenhouse production. Once signs of pests and diseases are found, measures should be taken immediately to prevent and control them.

7. Harvest

It takes about 70 days for cosmos to bloom from sowing. Before flowering, the plant's healthy growth should be maintained to ensure the quality and quantity of the flowers.

To sum up, the cultivation of cosmos is relatively simple. You just need to pay attention to the appropriate planting time, soil preparation, sowing method and maintenance management, and you can enjoy the beautiful scenery brought by cosmos.
