Planting Advice for Juniperus scopulorum Blue Arrow Trees

Our pot grown Juniperus scopulorum Blue Arrow can be planted at any time of year. Remove weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help Blue Arrow establish more effectively, sprinkle Mycorrhizal fungi in the hole.

Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree. Unless it is a particularly exposed location, there is no need to plant Blue Arrow Juniper trees with a stake and tie.

Aftercare Advice for Blue Arrow Juniper Trees

If you’re planting Blue Rocky Mountain Juniper in spring or summer, water well and regularly for the first few months. Make sure to keep an eye on young trees and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits to aid watering.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Juniperus scopulorum Blue Arrow Trees

Blue Arrow Juniper trees may benefit from light pruning to maintain their columnar shape if required. Simply remove any dead, diseased or awkwardly placed branches from your Juniper tree as and when you see them.
