How to Grow a Coreopsis from Seeds

You can easily use coreopsis seeds to grow several popular and beautiful varieties of coreopsis flowers. Coreopsis flowers are very easy to grow, and will grow in almost any area or environment in North America. Coreopsis plants are hardy, easy to grow, and easy to maintain. So, here is a quick how to guide on how to easily and properly grow coreopsis flowers.

Step 1 - Choose Coreopsis Seeds

Visit your local home improvement store’s garden section, or your favorite nursery and choose coreopsis seeds that produce the variety you wish to plant. Popular cultivars of coreopsis flowers are Moonbeam, Lime Rock Ruby, Double Sunburst and Zagreb. Save for the Lime Rock Ruby cultivar, most coreopsis cultivars are yellow or white in color. The Lime Rock Ruby cultivar is usually bright red, and is a very popular coreopsis variety cultivar. Choose the variety that suits your garden best, and take the seeds home.

Step 2 - Choose a Location

Coreopsis flowers are like any other type of perennial in that they require a lot of direct sunlight. So, before planting your coreopsis seeds, choose a location that receives 6 to 8 hours of direct sunlight on most days.

Step 3 - Prepare the Soil

Before planting your coreopsis seeds, make sure that you adequately prepare the soil where they will be planted. You should add a high quality mulch and all purpose fertilizer to the soil at a minimum. However, adding super phosphate, bone meal or even chicken or cow manure to the soil will help your coreopsis seeds even more by providing additional phosphate and other nutrients that will help your coreopsis grow faster and establish better root systems.

Step 4 - Plant Your Coreopsis Seeds

Plant your coreopsis seeds in about one quarter of an inch of soil, and make sure that the seeds are spaced about 12 inches to 18 inches apart. You do not want to plant the seeds to close to each other because of the average height of a coreopsis plant and their tendency to crowd each other.

Step 5 - The First Watering

The first watering of your coreopsis seeds should be rather heavy and you'll need to make sure the soil is thoroughly saturated. However, do not soak the soil to the point where the soil can no longer absorb water as this will cause valuable nutrients in the soil to be washed away.

Step 6 - Second Fertilization

About two or three weeks after you plant your coreopsis seeds, you should apply another application of a good high quality, high phosphate fertilizer. Also, ensure that the area is free from insects and pests, and consider adding another level of mulch to help protect the newly sprouting coreopsis flowers.

Step 7 - Prune and Transplant in the Spring

If you have properly prepared the soil, and the coreopsis plants receive enough sunlight, you will probably notice that the coreopsis plants have grown quite fast and may need to be cut back or pruned. While cutting back or pruning your coreopsis, you might want to consider dividing a few of them for propagation and transplant.
