Clematis Not Blooming After Fall Pruning: Timing and Root Shade

A clematis in SE Ohio (Zone 6) pruned to the ground last fall grew lushly but didn't bloom. Two likely causes:

1. Wrong Pruning Group

Clematis fall into three pruning groups. If yours is Group 1 or 2 (bloom on old wood), fall pruning removed the flower buds. Identify your cultivar to know its group.

2. Root Zone Stress

Clematis demand cool, moist, shaded roots and sunny tops. Mulch 3″ with shredded bark; plant a low perennial (not aggressive) on the south side to shade the base.

Action Plan

• Don't prune this year—let it bloom on whatever wood it has.
• Fertilize with 10-10-10 in spring, then 5-10-10 after first flush.
• Keep roots cool and moist.
• Be careful not to snap brittle stems at the crown.

Iowa State Extension has a clear PDF on clematis pruning groups (search "RG307 clematis").

Patience + correct pruning group = flowers next year.
