Propagation. By Seed

Sow at the end of March, or early in April, in drills one inch deep, and twelve inches apart. The seedlings will be up in five weeks. Weed and thin to twelve inches apart. In autumn, they will be fit for use like parsneps.

By Offsets

Old roots throw off these in the spring, when they may be slipped off", and planted in rows a foot apart each way.

Soil

A light loam is best, trenched, with a little manure dug in with the bottom spit.

To save Seed, let a few of the old roots run up in spring ; they will flower in July, and ripen their seed in the autumn.

Snow

Snow is one of the gardener's best shelters, and should never be removed from his out-door crops. It prevents heat from radiating from them; protects them from freezing, drying blasts; and, being a bad conductor of heat, thus prevents its escape from them. I have never known the surface of the earth, below a covering of snow, colder than 32°, even when the temperature of the air above has been 28°. - Johnson's Principles of Gardening.
