When is the best time to plant cosmos?

Marigold, also known as small marigold, is an annual herbaceous plant of the genus Tagetes of the Asteraceae family. It blooms in summer and autumn. The flowers are orange or dark orange in color and are very beautiful. If you want to plant it, when is the best time to plant cosmos? Let’s learn more about it below.

When is the best time to plant cosmos?

The best time to plant cosmos is in spring and autumn, from April to May in spring and from August to October in autumn. The temperature is suitable and the humidity is high during these two periods, which is conducive to improving the survival rate of cosmos. Marigold can also be planted at other times, but it must be planted in a greenhouse to ensure the temperature and humidity.

How to plant and maintain cosmos?

1. Seed planting

Marigold is usually planted using seeds. Marigold does not have high requirements for soil, but the soil used for planting must meet the two requirements of air permeability and drainage. Such soil is not prone to water accumulation, which is beneficial to the growth of marigold. Sow the seeds on the soil surface and cover with a thin layer of soil.

2. Transplantation

After sowing cosmos, water it well to keep the soil moist. If the temperature is controlled at 22℃-24℃, the seeds will germinate in less than a week. When the cosmos seedlings grow 4-5 leaflets, they can be transplanted with the soil ball.

3. Light temperature

Transplanting cosmos requires a flowerpot and increased light. Peacock grass originally likes sunlight, so you should place it in a sunny place. More sunlight is beneficial to its growth and can keep the plant green. Mauve is extremely cold-resistant, and as long as the temperature is above 10℃, it is a suitable temperature for its growth.

4. Watering and fertilizing

For cosmos, the soil in the flowerpot should be appropriately dry, which is very suitable for its growth, so the frequency of watering can be kept at three times a week, and there is no need to water it every day. In addition, except before and after the flowering period of cosmos, its demand for fertilizer is not too strong. Only before and after the flowering period, it needs to be fertilized a few times to ensure that it has enough nutrients to produce flowers.

5. Keep warm

In winter, you can move the cosmos indoors in advance and ensure that the indoor temperature is between 15℃ and 25℃ so that the cosmos can maintain normal growth. If the cosmos planted in the open field cannot be moved indoors, we can cover it with a layer of straw to keep it warm.

That’s it
