Peak growing season: June garden jobs in Oklahoma

  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. 20 weeks until the average first frost (November 1). Plan the fall garden now - most fall crops are sown 8-12 weeks before first frost. 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: napa cabbage, cabbage, borage, basil should be coming in. Picking regularly keeps beans, squash and cucumbers producing.
