Coneflower Pruning Tips

Coneflowers are related to black-eyed Susans that grow wild in meadows. They have noticeable purple petals with deep yellow to brown centers. Coneflowers are easy to grow in any garden, and pruning them will keep them blossoming throughout the summer season, and grow fuller too.

Removing Dead Plant Material

Right after the last frost, the coneflowers should have any dead stems and leaves removed. Use a pair of garden clippers to remove the dead part of the plant. Seeded plants with the pods on top should also be removed and can be saved for planting.

Keeping Stems Manageable

Because coneflowers tend to grow long stems, they can be trimmed down to a more manageable size before the flowers blossom. The plants should be trimmed down in July, and the flowers with the remaining stem placed in a vase so they do not go to waste. Trimming down the stems will encourage fuller growth of the plant during the following growing seasons.

Thinning Coneflower Plants

If the plants get too crowded, they can easily be transplanted elsewhere in the garden and survive well. Simply make sure no roots are damaged as they are dug up with the dirt, and move to another area where they can have space to grow.
