Waltham 29 Heirloom Broccoli Seeds, Pack of 100 Seeds
Waltham 29 Heirloom Broccoli Seeds, Pack of 100 Seeds
- Waltham 29, an heirloom broccoli variety, is grown as a flower, or head, vegetable with solid medium-sized dark blue-green heads. Broccoli is considered a superfood for its nutrient rich content, having a high (top 20) Aggregate Nutrient Density Index score (ANDI), or micronutrient-per-calorie density.
- This herbaceous annual, a member of the crucifer or brassica family, forms a compact, stocky plant with large crops of side shoots.
- It prefers full sun and organically rich, well-composted, consistently moist, well-drained loams but can survive dry spells. Open pollinated, it produces seed that will grow true to variety, ideal for seed saving.
- A cool-season, winter-hardy vegetable, the toughest of the cool-season crops, one of the first to be planted in the garden, it can be direct sown into the garden as soon as the soil is workable in early spring, before the last frost date.
- But it can also be started indoors and transplanted, spring and fall. It needs cold temperatures to germinate and grow, withstanding heavy frost and temperatures below 28 degrees, and becomes even sweeter with a light frost.

Choosing a Broccoli or Cauliflower Variety
All Broccoli and Cauliflower are packed with vitamins and nutrients, so when choosing what varieties to grow, you'll base your decision mostly on size and color. There are several compact types that don't require a lot of space, so they're the best choice for a limited gardening area. Heat tolerance is also a factor, especially for those living in the south. And if you're wanting to get your children to eat more healthy veggies, you might want to look at the more colorful, fun varieties!
When to Start Broccoli and Cauliflower
Broccoli seeds are best started indoors 7 to 9 weeks before the last frost, at a temperature of 70 to 75 degrees F. They can also be sown outdoors 2 weeks before the last frost. For a winter crop in zones 8 and warmer, sow in late summer. Expect germination in 10 to 14 days.
The same guidelines apply to Cauliflower, except when starting indoors, sow your seeds 5 to 7 weeks before the last frost. Expect germination in 8 to 10 days.
Since Cauliflower is more sensitive to cold than its cabbage-family relatives, you need to start it early enough that it has a chance to mature before the heat of the summer. Be careful, however, not to start it so early it gets damaged by the cold.
If your seedlings have been held too long or mistreated in some way before planting, they can create“buttons”, or small heads, that tend to flower prematurely.
Climatic elements such as extreme cold and drought can cause your plants to halt their full growth and form only “buttons”.
How to Start Broccoli and Cauliflower
Sow your Broccoli and Cauliflower seeds at a depth of 4 times the size of the seed, or ½ inch deep, and water thoroughly. Once the seeds have sprouted, be sure to keep the soil lightly moist.
Make sure the plants receive plenty of light -- fluorescent light for around 14 to 16 hours a day is also ideal for the fastest growth. You will want to keep the seedlings just a few inches below the light so they don't“stretch”and get“leggy". If you don't have fluorescent lighting, a south-facing window will do just fine.
Broccoli -- 45 to 60 days from sowing to harvesting
Cauliflower -- 30 to 80 days from sowing to harvesting
Don't allow your transplants to get too mature before moving them to your garden. If you do, they may become stressed by transplant shock.
A starter fertilizer applied when you transplant your seedlings will get your Broccoli and Cauliflower off to a good start, but it will not compensate for all the possible problems just mentioned.
Growing Tips: Broccoli and Cauliflower
Broccoli -- once the head is fully developed, but before the individual flowers start to open, cut the central head along with 5 or 6 inches of stem. Removing the central head will stimulate development of the side shoots, which will allow you to continue your harvest for several weeks.
Cauliflower -- the heads (curds) develop quickly under proper conditions, typically growing to 6 to 8 inches within 7 to 12 days after branching begins. Harvest the mature heads (they should be compact and firm) by cutting the main stem. If the heads develop a coarse,“ricey”appearance, they have over-matured. Cauliflower does not typically have side shoots, so you can compost the plants after the heads have been harvested.
Store fresh, unwashed Broccoli in your refrigerator's vegetable crisper for 3 to 5 days. Put it in a loose or perforated plastic bad, being sure not to store it if it's wet -- wet Broccoli will quickly become limp and can get moldy. Its best flavor and nutritional value will be maintained if storage is brief.
Uncooked Cauliflower can be stored in a paper or plastic bag in the refrigerator for up to a week. Place it stem side down to keep moisture from collecting in the florets.
