Full description for Juniperus spp. not yet available.
Juniper trees are shrubs or trees from dry areas in the northern hemisphere. The adult leaves are small, flake-shaped along the stems, and measure between 2 and 6 mm. The subjects are often separated between males or females, and bear either small ovoid cones or berries that darken in several years.
Plant my juniper
In open soil, plant preferably in autumn, possibly in early spring, outside periods of frost. Find a sunny location in ordinary drained soil - even sandy or stony - neutral or alkaline.
Make a hole 1/3 wider than the root ball, not mixing the soil layers. Soak the rootball if your juniper has waited long, then plant it without burying the root collar, which is the boundary between roots and branches, then water copiously.
For large juniper trees, place a solid stake facing the prevailing winds with a flexible attachment.
Mulch to avoid weeding.
In pots, plant in a mixture of garden soil and sand, in a pot proportionate to the size of the adult plant. It can vary enormously; some dwarf junipers do not exceed 30 cm while others reach 15 meters.
Water my juniper
Water regularly and generously for several weeks after planting or sowing, especially if you did it late in the season. After, you only have to worry about watering if your plant is potted. Outside of these conditions, it will manage on its own.
Repot my juniper
If you keep your juniper in pots, replace the topsoil with mature compost every 2 to 3 years.
Prune my juniper
The pruning is useless on the juniper trees, and it is better to limit it.
Take care of my juniper
After two years, you can remove the stake - it is no longer necessary, but could hurt the bark in the long run.
Mulch my juniper
Renew mulching in the fall at the base of your juniper trees. A mulching made of wood is perfect.
