Question My area of the country is renowned for granite outcroppings. Indeed, our cellar floor is bedrock granite, and hunks of granite are used in our landscaping. Our ornamental evergreens [cedars and junipers, but not yews]suffer from "browning" on the branch extremities.They are well nourished with compost and water. I'm surmising that they would benefit from dolomite lime being added to the soil to raise the Ph.My concern is that I read somewhere that cedars actually like an acidic soil. I would appreciate your advise. Gary Cousins
Answer Hi Gary, Check you pH. Junipers and true cedars should be fine in the 5.5 to 6.5 range. Adjust the pH to within that range if necessary. If you can rule out insect and disease problems and your pH is correct, then it may just be the bronze winter cast that many junipers take on. That's natural and nothing to be concerned about. But don't add lime until you know your pH. Jim
