How to plant cosmos

1. Choose planting soil

Marigold is relatively drought-resistant and afraid of moisture, so the soil used for planting must meet the requirements of air permeability and drainage. Using such soil will help it grow better, otherwise it will easily accumulate water and hinder the respiration and growth of the roots. Also, it is best to disinfect the soil before use.

2. Cultivation

1. The germination rate of seeds is usually not very high, so you need to use a box for simple seedling cultivation before planting.

2. Spray the disinfected planting soil with clean water, place the seeds that have been grown on the soil surface, and cover them with vermiculite after planting. It is best to cover it with a thin layer of straw, which can not only keep moisture but also block the sunlight.

3. Post-planting maintenance

After planting is completed, the temperature during germination needs to be controlled at 22-24℃. After waiting for about 2-5 days, the radicle will appear. After the seedlings grow out, remove the covering straw and give it appropriate light. When the seedlings have 4-5 leaflets, they can be transplanted.
