Woburn kale may be propagated by cuttings, six inches long, planted where to remain in March or April.
Buda kale is greatly improved by blanching under a pot, like sea kale.
The first crop sow about the end of March, or early in April, the seedlings of which are fit for pricking out towards the end of April, and for final planting at the close of May, for production late in autumn and commencement of winter. The sowing must be repeated about the middle of May; for final planting, during July, and lastly in August, for use during winter and early spring.
Their fitness for pricking out is when their leaves are about two inches in breadth; they must be set six incites apart each way, and watered frequently until established. In four or five weeks they will be of sufficient growth for final removal.
When planted, they must be set in rows two feel and a half apart each way, the last plantation may be six inches closer. They must be watered and weeded, and as they are of large spreading growth, the earth can only be drawn about their stems during their early growth. If during stormy weather any of those which acquire a tall growth are blown down, they must be supported by stakes, when they will soon firmly re-establish themselves.
For the production of seed, such plants of each variety as are of the finest growth must be selected, and either left where grown or removed during open weather in November, or before the close of February, the earlier the better, into rows three feet apart each way, and buried down to their heads. The seed ripens about the beginning of August.
