Coneflowers are in full bloom from summer until fall. These perennial wildflowers come in several types and bring some fantastic benefits to the garden. If you’re looking to plant some of these beautiful flowers in your own garden, this guide will take you through whether coneflowers can be planted in the fall.
When is the Best Time to Plant Coneflowers?
Early spring is the best time to plant or sow coneflowers. Coneflowers (Echinacea spp.) are perennials and rarely flower in their first year while they establish strong roots and foliage. Planting in spring gives them plenty of time to develop before flowering in their second year.
Starting coneflowers seeds indoors during late winter and early spring gives them a head start. Plant them out once all risk of frost has passed and average temperatures reach 65ºF (18ºC). You can also sow seeds directly into the soil once it’s warm enough.
Can Coneflowers Be Planted in the Fall?
Planting coneflowers in the fall mimics their natural life cycle. Coneflowers bloom for six to eight weeks between mid-July and October. Once flowering finishes, they will self-seed before dying back to their roots over the winter.
These seeds lay dormant in the soil throughout the winter before germinating and sprouting once spring arrives. This protects them from frost until the soil is warm enough. You can let your coneflowers self-seed or collect and sow them manually after flowering.
In warm climates, you can also plant mature coneflowers in the fall. This works best in climates that don’t get frost. If you do get frost, plant your coneflower approximately six weeks before the first fall frost is due. That gives the plant time to establish a good root system ready for the winter.
How to Plant Coneflowers in the Fall
Here’s a quick guide to sowing and planting coneflowers in the fall:
- Let the plants self-seed after flowering or collect the seeds manually to sow coneflowers in the fall. You can then sow them yourself.
- Sow the seeds into loose, well-draining soil in a location that receives full sun. The seeds will stay dormant over winter before germinating in spring.
- To plant a coneflower in the fall, pick a time approximately six weeks before the first expected frost. Weed the area thoroughly before digging a hole deep enough to fit the root ball.
- Loosen the root system before placing your coneflower into the hole. Make sure that the top of the root ball is level with the top of the hole.
- Fill in around your coneflower and firm down the soil. If rain is expected, there’s no need to water. If no rain is forecast, water your coneflower thoroughly.
- Apply some mulch around your coneflower to preserve moisture and protect the plant from the cold.
Although spring is the best time to plant coneflowers, you can also plant or sow them during the fall. Coneflowers naturally self-seed in the fall, allowing the seeds to lay dormant during the winter. You can let your coneflowers self-seed naturally after flowering or collect the seeds yourself and sow them manually.
