Can coneflowers be overwatered?
However, if they are overwatered or underwatered, you will miss the opportunity of watching them become a beautiful and colorful mainstay in the landscape. Coneflowers do best with dry-to-medium levels of soil moisture and are very drought tolerant. But they can dry out or get too much water.
Why are my coneflowers losing color?
Once pollinated, flowers no longer need to attract their pollinating suitors and, thus, begin to fade. Flowers may also change colors or fade when they are stressed. This can happen if a plant has just been transplanted.
How often should you water coneflowers?
Watering: Tolerant of drought, but does best in average, dry to medium moisture. Water regularly, but let soil dry out in between. Coneflowers need at least an inch of water weekly. Propagation: Divide clumps when crowded, about every 4 years.
Why are the leaves on my coneflowers turning yellow?
Echinacea also suffers from crown rot and leaf yellowing when it is planted in soil that does not drain properly. Rot is a fungus that infiltrates damaged stems and leaves of the plant. The signs of rot include deformed leaves, yellowing or blackening of the leaves and stems or yellowing of the roots.
