You might have noticed your coneflower leaves changing from green to black in patches.With long lasting blooms that pop with color, it is no wonder that Echinacea is one of the most popular flowers in the United States and the world. This means your plant is no longer healthy and has already been infested by a disease. There are two major causes of blackening coneflower foliage and they include Alternaria and bacterial leaf spot diseases.Īlternaria leaf spot begins as tiny black or brown spots on the plant’s leaves. ![]() These develop pale centers and become oblong as they expand. These spots can sometimes even cover the pores and vines of the plant.Īfter expansion, the centers of the spots become lighter. Along the midrib of younger leaves, the spots can be observed.īacterial leaf spot, as the name suggests, is caused by bacterial organisms. The symptoms of this disease differ slightly from those of Alternaria leaf spot disease. This disease also has dark brown or black patches just like in Alternaria. This location is frequently surrounded by a golden halo.īecause these patches do not travel on the veins, their spread is limited. You should always watch out for these two diseases and once they have gotten to a serious stage, they can kill the plant. Treatment for these two diseases is often done by spraying fungicide on the plants.

Should You Deadhead Coneflowers?ĭeadheading, or clipping of wilting flowers from a plant, helps to redirect the plant’s energy toward the healthy root and leaf growth instead of seed production. It also encourages flower blooming for plants that are not doing well as well as reblooming in a new season. Some species of coneflowers such as the Yellow and Purple do not require deadheading. However, some like the Black-eyed Susan must be deadheaded to ensure they grow flowers consistently throughout the season. Removing the spent flowers also reduces the rate of self-seeding in the plant. Make sure to deadhead plants before the seed heads ripen if you don’t want them to spread all over the garden. You can leave some of the seed heads on the plant so it can serve as food for birds during winter. Removing the flowers as soon as they finish flowering also helps to keep the garden looking neat and tidy.
