 This Month’s Tips

    • To reduce evaporation, water vegetable and flower gardens in the early morning. Water the soil rather than the leaves to reduce disease. Water deeply and infrequently to encourage root growth
    • Weed and fertilize rhubarb and asparagus beds. A mulch of compost or rotted cow manure works well as fertilizer. Water deeply to develop crowns for next year
    • Mulch with paper, plastic, sawdust, etc. to conserve soil moisture
    • Beets, bush beans, carrots, cauliflower, broccoli, lettuce, kale and peas planted in midsummer provide fall and winter crops. Get more tips on what to plant now in Fall and Winter Vegetable Gardening in the Pacific Northwest
    • Use chemical controls only when necessary and only after thoroughly reading the pesticide label. Consider cultural controls first, then physical and biological controls. Choose the least toxic options (insecticidal soaps, horticultural oils, botanical insecticides, and organic and synthetic pesticides) and use them judiciously

This time of year, we get a lot of questions from backyard apple growers about codling moth. Timing of insecticides matters because the sprays work best on the eggs and very young larva. This timing changes every year based on the weather. This year is a late year (cold and wet delays the moths from emerging). Right now (5/9) it looks like spraying should start around June 5th in the Salem area. BUT this date may change if the weather pattern changes.

 Non-pesticide options:

  • Use fruit protection bags (Fruit Sox/Footies/paper bags or other physical barriers) over the fruit to block the moth from being able to lay eggs on the fruit. These need to go on before the moth is active (based on the current weather get those barriers on before 5/23). Basically, as soon as the fruit are large enough tie a bag on each fruit to protect it. Time consuming but effective.
  • Surround (Kaolin clay) can act as a barrier/repellent.
