Why Are My Coneflowers So Leggy? Causes and How to Fix It

Learn why your coneflowers are leggy and discover practical tips for healthier, bushier growth with proper sunlight, fertilization, and spacing.

0 views

Coneflowers become leggy due to insufficient sunlight, excessive nitrogen, or overcrowding. To promote bushier growth, ensure they receive at least 6 hours of full sunlight daily. Limit nitrogen-rich fertilizer application as it encourages more foliage than flowers. Proper spacing allows adequate air circulation and light penetration, reducing legginess. Consider dividing them if overcrowded. Pruning early in the season can also encourage denser growth.
