Begin scouting and spraying for Japanese Beetles with liquid Sevin.
Apply second application of a complete fertilizer (12-6-6) in holes punched around plants or over the top as a broadcast.
Irrigate as needed; lawn needs 1 inch of water per week and established plants needs less than that, especially yews.
Scout for lawn diseases such as brown patch, dollar spot or root rot.
Spray Kelthane on spruce, junipers, pines and cypress for spider mites.
Scout for bag worms on evergreens.
