Waltham 29 Broccoli Seeds – 500 Heirloom Cold Hardy Broccoli for Fall & Spring Gardens

Waltham 29 Broccoli is a dependable heirloom variety prized by home gardeners for its compact, uniform plants and rich, flavorful heads. This cold-hardy broccoli performs especially well in cool weather, making it a favorite for both spring and fall planting. The plants produce firm, medium-sized central heads with tight blue-green florets, followed by a steady supply of side shoots that extend the harvest over a longer season.

Whether you grow it in raised beds, traditional garden rows, or large containers, Waltham 29 is a rewarding choice for fresh eating, steaming, roasting, and freezing. Its reliable growth habit and adaptability have kept it a standard in American vegetable gardens since the 1950s.

Planting & Care

Start Waltham 29 broccoli seeds indoors 6 to 8 weeks before the last expected spring frost, or sow directly in late summer for a fall crop. Sow seeds about 1/4 to 1/2 inch deep in a seed-starting mix, keeping the soil consistently moist but not soggy. Germination typically occurs within 7 to 14 days at soil temperatures around 65 to 75°F. Once seedlings have two to three true leaves, harden them off gradually before transplanting into the garden.

Broccoli thrives in fertile soil with regular watering. Mulch around plants to retain moisture and suppress weeds. Feed with a balanced vegetable fertilizer according to package directions. Harvest the central head while buds are still tight and green, cutting about 5 to 6 inches below the head. Side shoots will continue to develop for additional harvests. Watch for common cabbage-family pests and use row covers or other appropriate controls as needed.
