Growing Waltham Broccoli: A Complete Guide
Waltham broccoli is a classic variety that has earned its place in home gardens and farms across the country. Known for its reliable yields and excellent flavor, this heirloom cultivar produces large, dense heads that are perfect for fresh eating, steaming, or roasting. Whether you're a seasoned gardener or just starting out, Waltham broccoli is a forgiving choice that rewards you with consistent harvests.
Why Choose Waltham Broccoli?
This variety stands out for several reasons. Waltham broccoli plants are vigorous growers that adapt well to various climates and soil conditions. The heads mature uniformly, making it easier to plan your harvest. The flavor is sweet and tender, with minimal bitterness—a quality that makes it popular with families and chefs alike. Plus, after you harvest the main head, the plant continues to produce smaller side shoots, extending your harvest season.
Planting and Growing Conditions
Waltham broccoli thrives in cool-season weather, making spring and fall the ideal planting times in most regions. Start seeds indoors 4 to 6 weeks before your last spring frost, or direct sow in late summer for a fall crop. The plants need full sun—at least 6 hours daily—and rich, well-draining soil with plenty of organic matter.
Space plants 18 to 24 inches apart to allow for good air circulation and room to develop. Keep the soil consistently moist but not waterlogged. A layer of mulch helps retain moisture and keeps roots cool during warmer months.
Care and Maintenance
Feed your Waltham broccoli every 2 to 3 weeks with a balanced fertilizer or compost tea to support steady growth. Watch for common pests like cabbage worms and aphids—row covers can provide protection in early growth stages. Consistent watering is crucial; irregular moisture can lead to smaller heads or premature bolting.
Harvesting Your Crop
The main head is ready to harvest when it reaches 4 to 8 inches in diameter and the florets are still tight and green. Cut the head with a sharp knife, leaving 8 to 10 inches of stem attached. After harvesting the main head, continue caring for the plant—it will produce smaller side shoots that are equally delicious.
Waltham broccoli is a rewarding addition to any vegetable garden, offering reliable production and outstanding taste from seed to table.

OUR PLEDGE TO YOU
Agriculture and seeds provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations.
For the benefit of all farmers, gardeners and consumers who want an alternative. We pledge to you that we do not knowingly buy or sell genetically engineered seeds or plants. The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats.
We wish to support agricultural progress that leads to healthier soils, genetically diverse agricultural ecosystems and ultimately healthy people and communities.
We do not buy - OR - grow any seed from large corporations that make Genetically Engineered seeds. We don't touch that stuff and we never will.
The seeds we offer aren't like varieties you'd typically find at a garden center.
Every variety we offer is 100% OP (open-pollinated). Open-pollination means that you can safely save the seed after harvest and preserve a collection of heirloom seed for many generations to come.
To make it perfectly clear ... Our seeds do not contain any exogenously inserted embryogenesis deactivator genes caused by human intervention.
