Broccoli Waltham is an organically grown broccoli variety. It produces compact plants with blue green, compact heads with a delicious flavour. First harvest the central head and later the side shoots. Use this variety for a late summer or autumn sowing, not for a spring sowing, because it can't cope with warm weather. Broccoli Waltham can witstand cold and the harshest of winters.

Because broccoli is a cabbage variety it needs, like all other cabbage varieties, a lot of manure. Apply a generous ammount of compost to the soil and dig this through, about 1 - 2 months, before you start with sowing. Enrich the soil with some blood- and bone meal, 2 weeks before you sow.
Sow indoors from the middle of April. Sow in seedtrays filled with moist potting soil. Sow sparingly and cover the seeds with a thin layer of soil. Broccoli is a light germinator. Put the trays away in a light and warm room. Keep the temperature as even as possible and don't let the temperature drop during the night. Transplant the seedlings to seperate pots from the beginning of May. Harden the seedlings of by putting them outdoors during the day for approx. 10 - 14 days from the beginning of May. Put the seedlings on a sunny plot with half shade after this. Keep moist and weedfree.
Sow outdoors from the middle of May - the middle of July. Make a seed furrow of about 1 cm deep and moisten the soil, when it's a little dry, with some water. Sow the seeds, sparingly, in this furrow and cover them with a thin layer of soil and press the soil gently down. Keep the soil moist during germination but not too wet. Sow in rows approx. 45 cm apart. The seedlings emerge, depending on the temperature and the weather, after about 7 - 14 days. Thin the seedlings, when they're large enough to handle, to 30 - 35 cm. Water regularly. Keep the soil around the plants weedfree. Don't let the plants dry out and water extra during dry spells. Provide extra manure, when needed, by giving the plants some cowshed manure or blood- and bone meal. Broccoli is an annual and it's harvested in the same year. Winter broccoli is a biennial and is harvested, after overwintering in the soil, in the year after sowing. From the beginning of March till the end of April.
Protect your plants with nets against birds. Remove the nets when the plants are about 30 cm in size. Use a cabbage collar on the base of the young plants, to prevent the cabbage fly from laying it's eggs, because the larvae eat the roots of the plants. The seedlings and plants also need protection against slugs and snails. Harvest the central head first and the side shoots approx. 2 - 3 weeks later. You can keep broccoli fresh in the crisper compartment of the fridge for a couple of days.
