Peak growing season: July garden jobs in zone 3

  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. 9 weeks until the average first frost (September 15). Fall crops start now: bush bean, carrot, kale, radicchio. 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: cilantro / coriander, green onion / scallion, collard greens, napa cabbage should be coming in. Picking regularly keeps beans, squash and cucumbers producing.
