Juniper Browning Out
There may be several reasons for browning such as drought, poor drainage, root problems, competition for moisture and nutrients with other plants in the area, disease or insects, rodents/rabbits chewing bark from branch.
Here are some pictures of some of these issues- take a close look, perhaps with a magnifier on the needles and stems, and compare-
For a small fee you may submit samples that show both green and browning needles to MSU Plant Diagnostic lab. Include pictures of the shrubs- https://pestid.msu.edu
Lastly, hiring a certified arborist who comes on site and examines the whole planting and gives you an action plan may be the most direct way to go- find them by zip code here- www.treesaregood.org
