Growing Information
Growing Waltham 29 Heirloom Broccoli
‘Waltham 29’ is a classic heirloom broccoli prized for its dependable yields, excellent cold tolerance, and attractive dark blue-green heads. Plants produce uniform crops with good color and reliable performance in cooler growing conditions, making this variety especially well suited for spring and fall gardens.
Start ‘Waltham 29’ indoors about ¼ inch deep for transplanting. Space plants about 18 inches apart and grow in full sun to partial shade. Plants typically reach 18 to 30 inches tall and perform best in fertile, well-drained soil with consistent moisture.
Ready to harvest in about 74 days, cut the 4- to 6-inch main head once it reaches the desired size and the florets are still tight and compact. Cooler weather helps this variety perform especially well and supports high-quality head development.
Tender, flavorful, and dependable, ‘Waltham 29’ is excellent for fresh cooking, steaming, roasting, and freezing.

I’m very pleased with these. They aren’t thriving as well as the Godzilla Broccoli which I also purchased from here and planted at the same time, but I did get 100% germ rate, so I consider that a win!

I planted the seeds 2 weeks ago and they have germinated. They are about 3/4 in in height now. i'm hoping for a good harvest.
