How can you extend the Connecticut growing season?
Short answer: The most dependable way to keep gardening into fall is to grow cold-tolerant crops and use appropriate protection where it helps. Fabric covers, plastic or other structures can moderate conditions, but shortening daylight still limits growth. Tender crops such as tomatoes and peppers are vulnerable to frost.
How to decide
Separate tender and cold-tolerant crops
Tomatoes, peppers, cucumbers, and summer squash are poor candidates for continued outdoor production as fall temperatures fall. Cool-season crops generally offer a more realistic extension strategy.
Choose protection carefully
Row covers and other coverings can retain some heat and protect against light frost. Monitor conditions and manage ventilation, particularly beneath plastic when sunlight raises temperatures.
Expect slower growth
Even when frost protection succeeds, shorter autumn days mean less sunlight for photosynthesis. Plan fall plantings early enough to establish before growth slows.
Important: No cover guarantees protection through severe cold. Check actual forecasts and crop-specific limits before relying on a cover for frost protection.
