Sprouting Broccolis in Old Grimsby

Sow seeds in modules around 5th January - 20th January, about 1 cm deep. Keep them in bright, cool conditions and prick out the seedlings once they have a couple of true leaves.

From 26th January, keep the young plants moving steadily in good light and water them lightly but regularly. Avoid letting them become pot-bound, as checked growth can lead to weaker plants later.

Harden off seedlings over 15 days from 9th February to 23rd February. Give them a few days outside in shelter, then leave them out for longer each day before planting.

Plant out from 5th March, setting each plant 60 cm apart in rows spaced wider than that. Water in thoroughly straight after planting, then firm the soil hard around the stems so the roots do not rock in the wind.

From 12th March, cover the crop with fine mesh to keep out cabbage white butterflies and pigeons. Fit brassica collars round the stems at planting time or soon after to reduce cabbage root fly damage.

Start feeding from 2nd April and repeat every 28 days until 19th November. Use a high-nitrogen feed while the plants are making leaves, then stop before the coldest weather so the growth stays firm rather than soft.

Cut the first side shoots from 17th January and keep picking until 27th April. Harvest the shoots while they are tight and tender, cutting just above a leaf joint so more side shoots can follow.
