=For maximum crop.=--As soon as plants are set the ground should be well cultivated to the greatest depth practicable. We should remember that the tomato needs for its best development a very friable soil, while the tramping necessary in setting out the plants and gathering the fruit tends to compact and harden the soil. Often transplanting has to be done when the soil is wet, and we need to counteract the injury from tramping by immediate cultivation; but, at the same time, we must avoid the disturbing of the plants any more than is necessary, and all of our cultivation should be done with these points in mind. Just how it can be done best will vary not only with the location and the facilities available, but with the weather conditions, so that it is not well to attempt to give explicit directions any further than that one can hardly cultivate too deeply for the first seven days nor too often for the first 30 days after the plants are set, provided he avoids turning the soil when it is too wet. Even walking through the field when the soil is wet is injurious and should be avoided, in proportion as the soil is a clayey one. =At least expenditure of labor.=--I hardly need add to or change the suggestions given above for tomatoes at least cost, for any cultivation wisely given will probably do as much to reduce cost per bushel by increasing the yield per acre as any other expenditure. _In the garden_ it is advisable that from the time the plants are set until the fruit ripens, the surface soil about them be stirred every evening when it is not actually wet. =In the greenhouse.=--The surface of the soil should be kept open by frequent stirring or, as is the practice of some successful growers, it may be covered with a mulch of partially rotted manure. The plants should be watered only as needed to prevent wilt, and special pains taken to guard against too much moisture either in the soil or in the air, particularly on dark days. The night temperature should be uniformly about 60 deg. F. while in the day it should be 75 deg., and if it be bright and sunny it may go to 90 deg. or even higher. Air should be given freely whenever feasible to do so without too greatly reducing temperature. A moderate degree of moisture should be maintained in the air, care being taken that it does not become too moist, especially during dark days. There is more danger from the air becoming too moist than from its becoming too dry, though either extreme is injurious.
