Cultivation of Tomato Plants    
Tomato plants should be started in window boxes or greenhouses in late March so that they will be ready for the garden after the last frost. Use a soil of equal parts of sand, peat moss, and manure, and plant the seeds about a quarter of an inch deep. After covering, water them through a cloth to protect the soil and cover the box with a pane of glass. Keep the box in a warm place for a few days, then place it in a sunny window. After the second leaf makes its appearance on the seedling, transplant the plant to another box, placing the seedlings two inches apart. Another alternative is to put the sprouted seedlings in four-inch pots, setting them deeper in the soil than they stood in the seed bed. To make the stem stronger, pinch out the top bud when the seedlings are four or five inches in height.    
Finally, place the plants in their permanent positions after they have grown to be twelve or fifteen inches high. When transplanting, parts of some of the longest leaves should be removed. Large plants may be set five or six inches deep.    
The soil should be fertilized the previous season. Fresh, stable manure, used as fertilizer, would delay the time of fruiting. To improve the condition of the soil, work in a spade full of old manure to a depth of at least a foot. Nitrate of soda, applied at about two hundred pounds per acre, may be used to give the plant a good start.    
Plants grown on supports may be set two feet apart in the row, with the rows three or four feet apart depending upon the variety. Plants not supported by stakes or other methods should be set four feet apart.    
Unsupported vines give a lighter yield and much of the fruit is likely to rot during the wet seasons. To support the vines, use well sharpened stakes about two inches in diameter and five feet long. Drive the stakes into the ground at least six inches from the plants so that the roots will not be injured. Tie the tomato vines to the stakes with strings made out of strips of cloth, as twine is likely to cut them. Care must be taken not to wrap the limbs so tightly as to interfere with their growth. The training should start before the plants begin to trail on the ground.
