When to Plant Columnar Shrubs
The best time to plant these evergreen bushes is spring or fall, but this varies greatly depending on your location. In warmer locations avoid summer, but embrace winter planting! Cold climates should plant shrubs at least 6 weeks before the ground freezes or wait for spring.
How to Plant Columnar Shrubs
Dig a hole about twice the width of the root ball and not quite as deep as the root ball is tall. Place your Columnar Shrub level in the hole. This is especially important with narrow bushes so take a step back and ensure your shrub is straight. The top of the root ball should be slightly higher than the soil line. Backfill with the soil you dug out of the hole. Water deeply until the ground can no longer absorb water. Apply 1 to 2 inches of mulch to reduce weeds and watering needs and protect the roots.
How to Prune Columnar Shrubs
These narrow bushes are chosen for their natural shape so pruning usually isn’t necessary. Prune broken or dead branches when you notice them. Heavy pruning should generally be performed in late winter or early spring. A minor trim or shearing to keep your Columnar Shrub looking tidy can be done anytime except in mid to late fall (depending on your climate). Pruning often stimulates new growth which can be damaged by freezing temperatures.
Are There Any Columnar Shrubs for Shade?
Yes! The Green Mountain Boxwood and the Hicks Yew can grow in heavy shade. The Vokel’s Upright Hinoki Cypress and the Graham Blandy Boxwood tolerate part shade. For additional choices, be sure to browse our online garden center.
