If the average man wants to have a few sweet peas in bloom by the end of May and during June, he must sow a few seeds in autumn, but this is not recommended unless he has a frame or greenhouse. The end of September or early October is a good time to sow in boxes, putting the seeds in rows two to three inches apart, and one to one-and-a-half inches between the seeds, which should be planted about three-quarters of an inch deep. The plants should remain in the boxes in a frame until the middle of January, when they will be much benefited by being transplanted into boxes of fresh soil or potted off into small pots. After growth begins the plants should have the tops pinched off to encourage side growths which will spring from near the base.
Supposing these early plants are not desired, two other methods of sowing are practised which I shall now describe.
