In summer, it provides a splendor of flowers in the garden at home: the coneflower. From July, the perennial forms numerous flowers in purple, white or yellow, which make the outdoor area glow. But the plants of the genera “Rudbeckia” and “Echinacea” are “capricious”. If they suddenly stop flowering one year, then, of course, you wonder what went wrong in the care of echinacea. We list several possible reasons why the plant suddenly stops blooming.

Echinacea care: Common reasons why the echinacea plant does not bloom
For now: there are two major coneflower genera that are particularly popular as garden plants in this country. The genus “Echinacea” has pink flowers. The genus “Rudbeckia” blooms in bright yellow. There are some basic differences in care. The varieties that belong to the genus “Rudbeckia” will not bloom after cutting off what has faded. The Echinacea varieties will bloom again after cutting off the faded one. In today’s article we will take a closer look at the Echinacea genus. If the coneflower does not form any flowers or only a few, then this could be the reason:
Help, my coneflower is not blooming! This is the reason
- Wrong location. The coneflower needs at least 4 hours of direct sunlight, preferably in the afternoon, daily. Possible solution : Transplant outdoor plants in spring, move potted flowers.
- Loamy soil : An airy soil with good drainage is an absolute must. Solution : Loosen the soil, work in sand.
- Sunflowers need to be divided every three years. Immediately after transplanting or division, the plant will focus on root development and the formation of new leaves. The flowering period will be significantly shortened. Solution: Do not divide the echinacea too often.
- Overfertilization: coneflowers do well with lean soil. Too much fertilizer can have the opposite effect and slow growth. The result – flower formation will diminish. Nitrogen fertilizers will encourage leaf formation. Solution – It is best to work compost into the soil once in the spring and once in the fall. For potted plants, you can still apply liquid fertilizer once a month.
Incorrect coneflower care has a negative effect on flower formation.
- Irregular watering: In summer, plants are particularly sensitive to incorrect watering. The rule of thumb here is to water copiously from below, preferably early in the morning or late in the afternoon. Never allow the soil to dry out. Work a drainage layer of gravel or sand into the soil.
- Do not remove wilted shoots in time: To encourage flowering, remove wilted shoots in time. This involves shortening the shoots to 30 cm. The best time is in the evening or very early in the morning. Otherwise, the delicate cuttings may burn under the strong summer rays. Only when temperatures drop in early September, then you should stop cutting off the faded flowers. Solution: cut off faded flowers regularly until the end of August, and from then on, nurturing pruning is due in the fall.
- Even pre-cut young plants need time to develop. They may not form flowers in the first year, or they may flower later. The approximately delayed blooming of purchased young plants in the first year is usually due to the fact that garden centers cut off the new shoot tips in the spring. This encourages growth and ensures blooms in mid to late July.
What promotes flowering?
Fertilize Echinacea, but correctly
Annually work compost into the soil in the fall and spring. If necessary, in the summer, provide the flowers in the raised bed or in containers with suitable fertilizer. It is best to use a universal fertilizer with NPK 5.5 – 5 – 7.5. These liquid fertilizers contain a balanced combination of nutrients and important trace elements, which can reduce the negative effect of weather factors such as heat or heavy rainfall.
The right light conditions
Light conditions in a location can vary greatly depending on the planting and the season. In the spring, the corner next to the lawn was still in the sun all day, but in the summer, the shrub has developed magnificently, grown quickly and now casts shade on the plant. Trees, hedges or other perennials can also greatly affect the light conditions in the garden. So, if the flowers are not forming this year, then replanting may be appropriate.
Coneflower care: should I cut my plants after they have bloomed?
You can prune coneflowers back either in the spring or in the fall, after they have finished blooming. Fall pruning is recommended for plants over 4 years old, while young plants are best cut back in the spring. Follow these steps:
- Clean sharp pruning shears first.
- For young plants and container plants: Shorten shoots to about 20 cm after the end of the flowering period.
- For plants that have been growing in the bed for at least 5 years, cut the shoots close to the ground.
Do not cut off all faded flowers
If you regularly remove faded flowers in summer, you can extend the flowering period. But please do not cut off all faded flowers. Leave some flower heads, even in winter.
