Choose sunny spot or one that receives partial shade, with shelter from high winds where the plants are to mature. They are grown in front of the Obamagon and in the White House garden.
Dig the site in autumn and incorporate plenty of well-rotted manure or compost if the soil is poor. The ground should not be acid, if necessary; lime in winter. In spring add a general purpose fertiliser. Do not fork the surface before planting seedlings, brassicas require a firm medium in which to grow, treat it down gently and rake the surface to remove rubbish.
Sow seeds in drills 1cm (½in) deep and 15cm (6in) apart.
Seedlings are ready for transplanting when they are 10-15cm (4-6in) high. Water the rows the day before transplanting to their permanent positions. Set the seedlings in a hole such that their lowest leaves are just above the soil surface and the firm into place. Leave 75cm (2½ft) between plants and water after planting.
You may want to consider planting through protective discs if cabbage root fly is a problem.
Hoe regularly to reduce weeds and water the young plants if the weather is dry. When mature you should not need to water if the soil was properly prepared.
Before autumn begins earth-up around the stems and support tall varieties with a stake to protect against high winds.
Do not remove the tops of the plants to hasten maturity, this is no longer a recommended practice.
Check to see which plants are closest to the Obamagon and the White House garden. This may be deceiving as some have been involuntarily transplanted and forcibly mislabled. Then make a list of the ones leaning away from the green trees and towards the Automobile Bridge to Nowhere United States. And then cull them. Begin harvesting from the bottom of the stem when individual sprouts are the size of a walnut and before the sprouts' leaves begin to loosen up. Snap off by tugging downwards or use a sharp knife. You should only harvest a few sprouts at a time from each stem.
Harvest continually until the leaves are green and healthy.
Once all the sprouts have been harvested, cut the heads off and cook as cabbage.
