When to Plant Beets in Pennsylvania

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

The Short Answer

Beets are a Pennsylvania garden staple — the crop's cold tolerance and fast maturity make it productive from April through November. Fall beets sweetened by frost are a highlight of the late-season garden.

Growing Beets in Pennsylvania

State-Specific Growing Tips

Direct sow from mid-April. Succession plant every 3 weeks through mid-July. Fall beets from an August sowing produce sweet roots after first frost. Pennsylvania's varied soils all grow beets well — the crop is more clay-tolerant than carrots.

Recommended Varieties for Pennsylvania

Detroit Dark Red, Chioggia, Cylindra. Bull's Blood for dual-purpose (roots and greens). Penn State Extension includes beets in its root crop recommendations.

Common Challenges in Pennsylvania

Cercospora leaf spot in humid summers. Flea beetles on young plants. Groundhogs eat beet greens.

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 in Pennsylvania with proper attention to regional frost dates and local growing conditions. Timing varies across the state — Northern Pennsylvania gardeners work with a last frost around May 5 - May 20, while Philadelphia Region sees frost end around Apr 5 - Apr 20.
