Peak growing season: June garden jobs in Kentucky
- 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.
- 18 weeks until the average first frost (October 20). Fall crops start now: brussels sprouts. See the fall and winter garden guide.
- Check the undersides of leaves twice a week - catching pests early is most of the battle (pest identification guide).
