Use good watering methods to help all plants flourish in spite of the hot weather. Check plants frequently and water just enough to get water to the root zone to avoid overwatering and prevent root rot. Do not fertilize trees or shrubs, especially fruit trees, after mid-July. Fertilizing will encourage new growth that will not harden off in time to avoid winter injury. To discourage mites, hose dust from evergreens, leafy shrubs and hedges.
Mites are hot weather pests that thrive on the dusty undersides of leaves.
They suck plant sap and make leaves look yellow. Daily harsh water sprays will dislodge dust and mites, preventing a build-up of either. Weeds compete with desired plants for nutrients and water. Side dress vegetables and annual flowers with fertilizer. Always follow label directions exactly.
