Peak growing season: July garden jobs in Oregon

  1. Water deeply two or three times a week rather than a little every day - about an inch a week, more in heat. See watering a vegetable garden.
  2. 14 weeks until the average first frost (October 18). Fall crops start now: brussels sprouts, rutabaga, broccoli, cabbage. See the fall and winter garden guide.
  3. Check the undersides of leaves twice a week - catching pests early is most of the battle (pest identification guide).
  4. Harvest often: cabbage, basil, cauliflower, radicchio should be coming in. Picking regularly keeps beans, squash and cucumbers producing.
