Remove water sprouts from fruit trees, pull or rub off
Water one inch per week if dry, apply slowly to avoid run-off but conserve
Inspect plants for insect problems, aphids, leaf hoppers, cherry and pear slugs, don’t act unless problem is severe, give natural control a chance, spray with pyrethrin or rotenone (CAUTION: Broad Spectrum Killers)
Aphids: Late spring and summer: control ants, control aphids with M-Pede, insecticidal soap
Fruit Tree, Specific
Apples and pears: Late spring and summer: set traps, pheromone or water/molasses for codling moth in apples and pears, check blossom ends for codling moth frass, remove fruit.
Apples and pears: Late spring and summer: Isomate-C, mating disruption for codling moth, remove lose bark from tree, removes hiding place for pupa; wrap corrugated cardboard bands (ridges inward) around trunk of tree, encourage larvae to pupate, check if found, remove and burn, use for first and second generation moths.
Apples: continue to examine shoots and leaves for San Jose scale crawlers spray with summer oil
June drop, tree selects which fruits will develop, not well understood, probably based on number of seeds in fruit and photosynthesis
Thin apples (30-40 leaves per fruit), peaches (50-75 leaves per fruit) and pears after June drop, or leaving 1 fruit every 6 inches, who has time to count leaves (nutrient sink concept)
Continue scab and mildew control, if weather moist removes spent flowers from annuals to encourage more bloom
Scale insects: the best time to control is during the crawler stages, from late June, July, and into August, spray with horticulture oil or fish oil
