You can put down a rye grass that will live only during the cool months is this area. Even perennial rye grass will not survive our hot summer months. I think that you should always have your lawn soil analyzed to get best idea on fertilizer. Contact your local Ag Extension agent for details on this procedure. It is very inexpensive ($7.00 last year), and worth every penny. However, if you choose not to get a soil analysis, be sure to get a complete fertilizer, that is slow release. Since you will probably fertilize fescue twice per year, you need to make sure that you have a good mixture of Nitrogen, Phosphate and Potassium, not something that is almost all Nitrogen. A good fertilizer for your shrubs and bushes is Pennington Nursery Special 14-7-7.
