Spring Pruning and Feeding for Knockouts, Climbers, and Miniatures in Wisconsin

Pruning by Type in Cold Climates

In Milwaukee (Zone 5), where winters are severe:

Knockout shrubs: Remove dead/diseased canes, then cut back by 1/3. Don't prune by bud swell—cut until pith is green.
Climbers (Joseph's Coat, Blaze): Minimal pruning—only to control size. Leave height for winter dieback buffer.
Miniatures: Cut back by half, remove dead wood.

Now (spring): Handful of rose fertilizer around climbers; half handful for shrubs; 1 tbsp for minis.
Early July: Repeat same amounts.
Stop after mid-July to harden canes.

'Joseph's Coat' can be grown as a 4-ft shrub if climbing space is limited.
