September Gardening Tips
- Start Tomato, Pepper, Cucumber indoors now to give them a head start before transplanting outside.
- Tomato, Pepper, Cucumber can be transplanted outside this month. Harden off seedlings over 5–7 days before planting out.
- Direct sow Corn, Beans (Bush), Carrot straight into the garden — no transplanting needed.
- Protect tender crops from early frost with row cover — this can extend your season by several weeks.
