Hypericum (St. John's Wort) Not Blooming: Late Pruning Likely Cause

A gardener's hypericum bloomed 3 years, then nothing after late spring pruning, cold winter, more shade.

Diagnosis: Pruned Too Late

Hypericum blooms on new growth. Prune immediately after flowering (mid-summer). Late spring pruning removes flower buds.

Don't prune again this year. Expect blooms next year. Cold winter and shade are secondary factors.
