Junipers come in many shapes and sizes but all have similar requirements. Once established, junipers will tolerate a wide range of conditions, including sub zero temperatures, drought, heat, and salt air. Junipers are conifers but they produce berry like fruits instead of cones.
Choose a site with good drainage. Junipers will tolerate poor soil but they will not tolerate wet feet. Determine the mature size of the plant and choose a site accordingly. Most junipers prefer full sun but some will tolerate some shade. They will tolerate poor soil as long as it is well drained.
Dig a hole twice as wide as the root ball and as deep as the container. Mix some organic material (peat moss, leaf mold, manure, or compost) into the soil that has been removed. The ration should be one-third organic matter to two-thirds soil.
Remove the plant from its container. Try to put they roots straight so they don't girdle the plant later. If the roots are a dense mass, score the root ball deeply in three places with the pruning shears. Prune any visible damaged roots. Place the shrub in the planting hole.
Fill in around roots with the mix. When you have filled in the hole half way, fill the planting hole with water. As it drains it will settle the planting mix around the roots. Continue filling in the hole and water again.
Check the moisture level of the soil for the next few weeks and water as needed. The soil should be moist but not wet. Once the juniper plant is established it will be drought tolerant.
