Ideal Pruning Times

Post-Bloom (Fall)
- After the blooming period, typically in late summer or early fall, you may prune back spent flowers to prepare the plant for the next growing season. This timing helps the plant allocate energy to root and stem health for the upcoming spring.
Steps for pruning endless summer hydrangeas
Spring Pruning
-
Gather Your Tools
- Sharp pruners or scissors, gloves, and disinfectant for your tools.
-
Assess the Plant’s Structure
- Look for any dead or damaged branches, which should be your first cut.
-
Cut Back to Healthy Buds
- Trim the older stems to about one-third their length, cutting to just above a healthy bud. This encourages new growth.
-
Remove Deadwood
- Identify any branches that are completely dead and prune them at the base.
-
Shape the Plant
- Encourage a compact shape by selectively removing any stray branches that disrupt the overall aesthetic.
Fall Cleanup
-
Remove Dried Blooms
- After the flowers have faded, gently cut the old blooms off, making room for the new ones.
-
Mulch for Protection
- Apply a layer of mulch around the base to protect the roots over winter and conserve moisture.
Common Mistakes to Avoid
- Pruning at the Wrong Time: Never prune in the fall or winter since you might cut off valuable flower buds that will bloom in spring.
- Over-Pruning: Be cautious not to remove too much; aim for about one-third of the plant to maintain its structure.
- Neglecting Deadwood: Failing to cut back dead stems can hinder new growth and can lead to diseases.
