Blueberry juniper trees (Juniperus ashei) are also known as Ashe juniper trees and are native to Texas. The male blueberry juniper tree produces large amounts of pollen from December to February, according to Central Texas Tree Experts, so if you are prone to pollen allergies you may want to reconsider planting this tree, or plant a female tree. Otherwise, blueberry juniper trees are easy to care for and will grow in poor soil or good, sun or shade, and it require little water. To attract birds to the landscape, plant a female tree as the males do not produce the berries that birds find so tasty.
Water the blueberry juniper tree when the soil is completely dry. Give it a good flooding and then allow the soil to dry prior to watering again.
Fertilize the blueberry juniper tree in early spring with an azalea fertilizer, at the rate listed on the fertilizer package. Spread the fertilizer out to the dripline and water afterward. Never apply fertilizer on days when the temperature is over 85 degrees F.
Prune the tree to keep it to the shape you want. Otherwise, no pruning is necessary.
Inspect the blueberry juniper periodically for pests. The tree is especially attractive to aphids, which can be washed off the tree with a strong blast of water from the hose. Insecticidal soaps work well for more extensive infestations.
