Planting & Care

Start Waltham 29 Broccoli seeds indoors 6-8 weeks before the last frost date for a spring crop, or 8-10 weeks before the first fall frost for an autumn harvest. Sow seeds 1/4 inch deep in seed-starting mix, keeping the soil moist and at 65-75°F for best germination. Once seedlings have 2-3 true leaves, harden them off and transplant into the garden after the danger of heavy frost has passed. For fall planting, direct sow or transplant in mid-to-late summer.

Broccoli thrives in fertile, well-drained soil with consistent moisture. Water regularly to prevent stress, and mulch to retain soil moisture and suppress weeds. Fertilize with a balanced organic fertilizer when plants are about 4 weeks old. Watch for common pests like cabbage worms and aphids; row covers can help protect young plants. Harvest the central head when it is tight and before yellow flowers open, then continue to harvest side shoots for an extended crop.
