|My hedges are dying. they have been OK for at least 20 years, not they seem to be drying out (leaves brown and dry) no new leaves. Why? Recommend replacemnts evergreen 2-3 ft high|
|I'm not sure what might be wrong with your hedge shrubs. If they are turning brown, there's probably a root problem. The most common is root rot from poorly draining soils. But the browning might also be caused by dog urine or from lack of water. I can't really diagnose the problem without seeing the plant. Try watering once each week - twice a week when the weather is really hot. When you water, apply the water slowly so it has a chance to soak into the soil. Inspect the plants for signs of insects, as well. Wish I could offer more help!
As for new plant recommendations for evergreen shrubs they include: Taxus, green gem Boxwood, green velvet boxwood, Blue Princess & Prince Hollies and globe arborvitae.
