When to Plant Turnips in Maine

A fast-growing, cold-hardy root crop that's underappreciated. Both the root and the greens are delicious.

The Short Answer

In Maine, soil conditions are an important factor for turnips. Acidic, rocky soils. Blueberries thrive naturally. Raised beds common to deal with rocks. Amendment with lime needed for many vegetables. Direct sow 3 weeks before your last frost date. Turnips can also be planted in fall, 8 weeks before your first frost.

Growing Turnips in Maine

Turnips in Maine's Climate

Turnips are a fast, cold-hardy root crop perfect for extending your short season. Direct sow 3 weeks before last frost and again in late August for frost-sweetened fall harvest. Both roots and greens are edible, doubling the crop's value. Hakurei Japanese salad turnips are especially quick — ready in 30-35 days.

Soil Considerations for Maine

Acidic, rocky soils. Blueberries thrive naturally. Raised beds common to deal with rocks. Amendment with lime needed for many vegetables. Loose, well-drained soil is especially important for turnips since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Maine Climate & Growing Season

Short growing season but long summer days help. Maritime influence on coast. Season extension techniques very valuable. Turnips can handle frost well, which is an advantage in Maine's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Maine: Northern Maine (3b, 4a, 4b) has a last frost around May 20 - Jun 5, while Southern/Coastal Maine (5a, 5b, 6a) sees frost end around May 1 - May 15. This difference matters for turnips — but turnips handle frost well, so the timing difference is less critical.

Growing Tips

Great for spring and fall planting. Harvest small for tender roots. Fall-planted turnips taste sweeter after a frost.
