Lettuce
This plant should be started in the hotbed if there is one. The seedlings should be transferred to the cold-frame before they have attained much size, and left there until the ground becomes warm. Very fine lettuce, however, can be grown from seed sown directly in the open ground about the first of May, if the soil is warm and rich. A fertile soil is quite important, as it is necessary to bring on a rapid growth in order to have the plant crisp and tender. Slow development gives a comparatively worthless article.
The All Heart variety is excellent for spring and early summer use. It forms a solid head, and is very crisp and tender, with that rich, buttery flavor that the lover of this plant insists on. Mammoth Salamander is one of the best late-season kinds.
