cold frame

In the spring a mild hotbed, a cold frame or a nursery bed in the garden may be used, according to the earliness of planting.

The nuts from these crosses were stratified in sand in a cold frame, dug up, and planted in the greenhouse in early March.

Seed is sown in early spring, either in a cold frame or in the open ground, and the seedlings transplanted in early summer.

The drills may be made in a cold frame during March or in the open ground during April.

A fair return from a cold frame to which the plants have been transplanted ranges from $3 to $7 during the winter months.
