À propos Waltham broccoli 29
Waltham 29 broccoli produces a beautiful inflorescence and then numerous new shoots. A perfect cultivar for the gardener.
The open-pollinated broccoli we sell is prone to flowering in spring for a variety of reasons, including increased photoperiod and frost sensitivity. One advantage is that once the inflorescence is harvested, they produce more.
These broccolis produce best when grown in the fall, so sow in July for transplanting in mid-August.
Growing tips for Waltham Broccoli 29

Green broccoli
Common green broccoli produces a dense, fleshy, and large flower bud. Unfortunately, these are mostly hybrids that are offered to us: they produce a uniform, good-sized inflorescence, with few secondary shoots. Open-pollinated cultivars like Waltham develop, after their main bud, a good number of secondary buds until the first hard frost. These secondary shoots are less suitable for marketing, but they are perfectly suited to the needs of a household.

Growing conditions for broccoli
Like headed cabbage, broccoli thrives in cool conditions and a decreasing photoperiod. The plants are frost-resistant. However, exposure to temperatures below 0°C during their vegetative development encourages the production of small inflorescences; spring broccoli crops must therefore be grown under protection, either under a floating row cover or a mini-tunnel. High heat and lack of water tend to cause the buds to open prematurely. For spring, choose early cultivars so that the plants are exposed as little as possible to the summer heat during flower induction. The best results are obtained with autumn crops. In this case, opt for late cultivars.
Broccoli Crop Rotation
Broccoli is grown in the second year of rotation after growing plants that require young compost.
Broccoli Companionship
Broccoli is associated with other leafy vegetables that are grown like it in the second year of rotation with additions of well-rotted compost. Thus, broccoli grows well alongside various lettuces and chicories, celery, Swiss chard, spinach and leeks. It could also be associated with celeriac, radish and beetroot. Most aromatic plants such as thyme, sage and savory are beneficial to it, as they make them more difficult for pests to spot. Marigold, nasturtium and French marigold are
good neighbors. To save space, early broccoli grown under agrotextile or mini-tunnel should be combined with radishes and turnips, two species that also require protection against the fruit fly.
