When to plant Blue Rug Juniper

Plant Blue Rug Juniper in spring once the soil is workable, or by very early fall at the latest: an evergreen needs its roots down well before the ground freezes. For the middle of its hardy zones 3 to 9 range, that is March to May, or August on the fall side.

Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.
