My neighbour is having problems with her cedars. The tips are turning brown. Can you give any suggestions?
Some browning is normal; as part of growth, every tree will lose some leaves. Here’s what you can tell your neighbour about the needs of her cedars in terms of preventing more loss:
- Cedars require more water than some trees.
- The soil they are in will benefit from annual applications of compost and mulch. Don’t smother the base of the tree; give it at least 4 inches of space.
- Fertilize three times with a 30-10-10 organic compound. The ideal months are May, June, and July. Follow the directions on the packaging. Do not fertilize after those months.
- Hose down with water to eliminate the presence of aphids or spider mites just in case these are causing the problem.
