When to Plant Beets in Delaware

Two crops in one — eat the roots and the greens. Beets are cold-hardy and surprisingly easy.

The Short Answer

In Delaware, soil conditions are an important factor for beets. Sandy soils in south, clay loam in north. Generally well-drained. Slightly acidic. Direct sow 3 weeks before your last frost date. Beets can also be planted in fall, 8 weeks before your first frost.

Growing Beets in Delaware

Beets in Delaware's Climate

Beets are a reliable three-season crop in your climate. Direct sow from early spring through mid-July, plus a fall planting in August. They handle your clay soils better than most root vegetables. Fall beets sweetened by frost are the highlight — the cold converts starches to sugars for noticeably better flavor.

Soil Considerations for Delaware

Sandy soils in south, clay loam in north. Generally well-drained. Slightly acidic. Loose, well-drained soil is especially important for beets since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Delaware Climate & Growing Season

Moderate climate with maritime influence. Good growing conditions for a wide range of vegetables. Beets can handle frost well, which is an advantage in Delaware's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Delaware: Northern Delaware (7a) has a last frost around Apr 10 - Apr 25, while Southern Delaware (7b) sees frost end around Apr 1 - Apr 15. This difference matters for beets — but beets handle frost well, so the timing difference is less critical.

Growing Tips

Each beet 'seed' is actually a cluster — thin to one plant after sprouting. Harvest at 1.5-3 inches for tender roots.

Companion Planting

Plant beets alongside these companions for better growth:

Onions Lettuce Cabbage Broccoli

Keep beets away from:

Pole Beans

The Bottom Line

Beets can be grown successfully across Delaware, but your exact planting dates depend on which region you're in. Northern Delaware gardeners should plan around a Apr 10 - Apr 25 last frost, while those in Southern Delaware can typically plant earlier.
