When is the best time to sow Coreopsis seeds?

Coreopsis seed planting method and steps

1. Preparation of Coreopsis seeds before sowing

Coreopsis seeds cannot be sown directly. Seeds need to be adequately prepared before sowing. First of all, while ensuring the quality of seeds, some methods can be used to break the seed dormancy period. The simplest method is to allow the seeds to absorb water and swell. In addition, they should be sown in a place with sufficient sunlight, fertile soil, good ventilation and drainage.

2. Sowing of Coreopsis seeds

Coreopsis seeds can be soaked in warm water for a few hours, then wiped dry or left to dry naturally before being sown. Many issues need to be paid attention to during the sowing process, but Coreopsis is not very strict about the planting method and planting depth and density.

3. How to care for Coreopsis

The maintenance and management of Coreopsis is relatively simple. When the seedlings grow one or two leaves, apply nitrogen fertilizer once to supplement the nutrients they need. Then during its growth process, apply nitrogen fertilizer two or three times more, and appropriately combine it with phosphorus fertilizer and potassium fertilizer to ensure sufficient nutrients.

Coreopsis likes a humid environment, but is not tolerant to waterlogging. Therefore, you cannot water it with a large amount of water at one time. Instead, water it in small amounts frequently as long as its growth needs are met. Aphids and other pests often appear during the growth period of Coreopsis. Therefore, you should spray pesticides in time according to the growth status of Coreopsis to prevent disasters.
