TOMATOES IN THE GREENHOUSE 181 Planting Tomatoes As soon as they have nicely filled these pots with roots and before they become root-bound, the plants will be fit for setting out. This will occur under favourable con-ditions about three weeks after potting, so that we come to the early part of April or not later than the middle. From the time of planting onwards they will grow without fire-heat, though they benefit by the pipes being slightly warm. We will presume that the plants are to be set out on the greenhouse staging. Having cleared off the shingle or ashes, let two boards be set on end at a distance of eight or nine inches apart and make the requisite arrangements for keeping these in place. Cover the bottom with leaves, and over this put some soil, making it fairly firm. A depth of two inches will be quite sufficient. It now remains to knock the plants out of the pots, extract the cracks and set them at a distance of eighteen inches apart. Fill in with soil and make this firm about the ball and sufficient to cover the balis of soil by about an inch. It is essential that the soil be made quite firm to induce sturdy and short-jointed growth and the earlier formation of fruit. No stimulant of any kind should be used in the soil.

The Training of Tomatoes There is no great problem in the training of a tomato. The method found most generally satisfactory is to train it to a single stem and to pinch out every side growth as it appears. These side growths form at the base of the
