June Gardening Tips
- Sweet Potatoes can be transplanted outside this month. Harden off seedlings over 5–7 days before planting out.
- Direct sow Corn, Carrots, Beets straight into the garden — no transplanting needed.
- Water deeply but less often to encourage deep root growth. Morning watering reduces disease risk.
