Garden Planner: By Mary James

San diego lawns typically are warm-season or cool-season grasses; and this month care for both changes. To help blue grass, fescue and other cool-season lawns endure the heat, allow them to grow taller by setting mower blades at 3 to 4 inches and keep them well watered. On the other hand, warm-season grasses like Bermuda or St. Augustine should be cut short — 1 inch or less — to help reduce thatch build-up. Water deeply but less often to keep growth in check. To reduce use of chemical fertilizers, consider the use of a mulching mower that cuts and re-cuts grass into fine pieces that can be left as mulch on either kind of lawn.
