Planting and soil

Plant in spring or fall with the crown at soil level. Avoid low, wet spots.

Feeding

None.

Pruning

Trim only to keep it off paths, cutting back to a side branch. Don't shear into bare wood; it won't regrow.

Through the year

Evergreen. Silver-blue in summer, plum-tinged in winter.

If something's off

Root rot in wet soil. Tip blight browns new growth in wet springs; prune out dead tips.
