Witchita Blue Juniper

Wichita Blue Juniper

The Wichita Blue Juniper (Juniperus scopulorum). A conifer and does very well around the southwest.  It is drought tolerant and requires very little maintenance.  It does not produce berries or cones.

It grows to about 15. ft tall and 8 ft. wide.  It makes a good privacy border wall.  It retains its bluish tinge color all year-long.  Water consistently the first 2-3 years after planting.  Then cut back to about once per week during the hot summer months.

If you are looking for a good looking border tree that will screen out traffic or intrusive neighbors this tree will do the job.

Insect problems

It is susceptible to spider mites and we recommend spraying with a mite control insecticide at the first site of these insects.  You can also spray the tree with plain water from the top down to remove these insects.  Use a good spray nozzle to remove mites and old foliage.  Spider mites look like a brown spider webbing usually around the bottom of the tree.  Spider mites love all pines, cypress and juniper plants and thrive in dry hot conditions.  Borers and bagworms do attack this tree but this is rare around the southwest.  A good systemic insecticide will kill these pests.

Organic Insecticides

You can use Neem oil to kill mites and aphids. Neem oil is derived from the berries of Pyrethrum is also an organic insecticide.  It is derived from the Mum flower (Chrysanthemum). Do NOT confuse them with the following Pyrethroids and Permethrin as these are toxic to humans. Pyrethrins are toxic to insects and not to humans. However, it is toxic to fish and amphibians.

Another product to use is horticulture oil this will not kill insects but it does smother the insect larvae thus keeping it from hatching. It is best to apply this during early spring.  In the southwest, it is usually around early March.
