Landscaping Uses

Plant the Techny in full sun to partial shade as a living fence or hedge that blocks unsightly views, reduces noise, and shelters your property from harsh winds. Its tight branching structure makes it ideal for screening along property lines, and multiple trees planted in rows create an impenetrable green barrier. This tough conifer adapts beautifully to any soil type and tolerates coastal salt spray, making it perfect for challenging landscape positions where other trees struggle.

Planting & Care

Dig a planting hole as deep as the root ball but twice as wide, using the native soil to backfill—no amendments needed. Apply a 3-inch layer of shredded hardwood mulch around the base, keeping it away from the trunk. Water weekly during hot months to maintain moist (not waterlogged) soil, then rely on natural rainfall once established. In spring, apply a balanced evergreen fertilizer following package directions. For a neat hedge appearance, shear lightly in late winter through early spring.
