Planting and Growing Coreopsis

The coreopsis is a beautiful perennial flower native to North America that adds a burst of color to any flower garden, landscape or even open field area. The coreopsis is one of the easiest perennials to grow and care for, and will grow in most climate regions in North America. Here is a handy how-to guide on how to plan, grow and care for a coreopsis perennial.

Step 1 - Buy Coreopsis Seeds

Although you can buy a coreopsis seedling plants, growing coreopsis from seed y will usually make for more robust and more beautiful blooms and flowers. Visit your local nursery or garden section of a home improvement store and purchase coreopsis seed varieties that are appropriate for your area and will bloom into the color variety that you desire.

Step 2 - Choose a Good Location

Coreopsis perennials are like any other type of perennial in that they needed a lot of direct sunlight. So, choose a planting location that receives at least 6 to 8 hours of direct sunlight every day. If you cannot find an area that receives direct sunlight for this period of time, you may choose a lightly shaded area - but the coreopsis will probably have fewer blooms and flowers.

Step 3 - Sow Your Coreopsis Seeds

As with any other type of perennial seed, coreopsis seeds need to be planted as early in the growing season as possible. Sow your coreopsis seeds in about one quarter of an inch of soil, and make sure to space your coreopsis seeds about 12 inches to 18 inches apart.

Step 4 – Mulch and Fertilize

Once you have planted the coreopsis seeds, you'll need to add a high-quality mulch and general-purpose fertilizer to the soil covering the seeds themselves. Also, you might want to consider using a light super phosphate application or adding peat moss or bone meal to the soil as well. Coreopsis seeds benefit greatly from the added nutrients that these types of products offer.

Step 5 - Water the Coreopsis Seeds

Thoroughly water the soil where you have planted the coreopsis seeds. Your first watering will need to be thorough, but make sure you do not soak the soil. Just water the soil to the point to where water is starting to build up on the surface.

Step 6 – Fertilize Again

Approximately 2 to 3 weeks after you plant the coreopsis seeds, add more fertilizer to the area where the coreopsis seeds have been planted. The added nutrients from the fertilizer will help the coreopsis survive any frosts that may occur, as well as help  establish better root systems.

Step 7 - Cut Back Old Growth

Once the coreopsis plants start to grow, you will need to periodically cut them back to allow for more blooms and flowers. You can use a regular pair of bypass pruning shears to accomplish this.

Step 8 - Divide Your Coreopsis in the Spring

In order to promote even more blooms and flowers from your coreopsis, it is a good idea to divide the plants in the spring. Divide the root systems of several of your coreopsis plants and plant them in the same way and at the same soil depth as you did your original coreopsis seeds.
