Plant fescues when fall temperature reach about 75 F. The next best time to plant fescue seeds is when rising temperatures in spring reach 60 F. Summer isn't a good time to plant fescue lawns, because fescue grass tends to go dormant during periods of high temperature.
Fertilize blackberry bushes in the early spring just as they begin to put forth new growth. Use 1 pound of 20-20-20 granular fertilizer for every 25 feet of row, broadcasting it evenly around the base of your shrubs. If you use 10-10-10 fertilizer, apply 2 pounds for every 25 feet of row. Feed blackberry bushes again when they are blooming in midsummer. Do this only if your bushes are not thriving. Apply 1/4 pound of a 34-0-0 fertilizer, also called ammonium nitrate, for every 25 feet of row.
