Grow Nutrient-Packed Broccoli Waltham 29 Seeds in Your Garden

A reliable, heirloom broccoli variety known for its cold tolerance, producing 4-6 in. dense blue-green heads and abundant side shoots perfect for late fall harvests. Developed in Massachusetts, it thrives in cool weather and with consistent moisture. This heirloom variety is not just delicious, it's a superfood packed with antioxidants and essential nutrients that support overall health.

Why Choose Broccoli Waltham 29 Seeds?

Broccoli Waltham 29 is an open-pollinated, non-GMO heirloom variety that delivers:

  • High yields of flavorful, nutrient-dense heads
  • Excellent cold tolerance (down to 20°F)
  • Multiple harvests from the same plant
  • Rich in vitamins C, A, B6, potassium, and fiber
  • Contains cancer-fighting sulforaphane

Easy Growing Instructions

For spring crops, start your Broccoli Waltham 29 Seeds indoors 8 weeks before the last frost. Plant seeds 1/2" deep in pots with growing mix and place in bright light. Transplant seedlings 2' apart after 5 weeks.

For easier fall crops, plant seeds directly in the garden 1" deep and 6" apart, thinning to 2' spacing when seedlings reach 6" tall. This cool-season vegetable thrives in daytime temperatures in the 60s.

Care Tips for Bountiful Harvests

Ensure your broccoli plants get:

  • Full sun (6+ hours daily)
  • Rich, compost-enriched soil
  • Regular deep watering (mulch helps retain moisture)
  • Monthly organic fertilizer or compost tea

Each packet contains 50 seeds (plants a 24' row with 12 plants) and matures in just 85 days. You'll enjoy not just the main crown, but also delicious side shoots that continue producing.

Versatile in the Kitchen

Enjoy your homegrown broccoli:

  • Raw for maximum nutrition
  • Lightly steamed to preserve vitamins
  • Roasted or grilled for incredible flavor
  • In stir-fries, soups, and salads

Every part of the plant is edible, from the nutrient-packed crowns to the stems and leaves.
