General Care of the Garden
A garden bears close acquaintance, and the successful gardener is the one who keeps in close contact with his crops throughout the entire growing season. A visit to the garden during the early morning while the dew hangs heavily upon every plant will reveal the happenings of the night. Perhaps some insect attack has started or some injury has occurred which requires immediate attention. A garden requires a little attention almost every day and responds in direct proportion to the care bestowed upon it. The size of the garden should be such that its care will not prove a burden. A small garden intensively cultivated is much better than a larger one which is allowed to grow to weeds.
Holding Moisture
The frequent stirring of the surface soil with a steel rake, especially during dry weather, will stimulate the growth of the crops and control weeds. The surface should also be stirred after a rain just as soon as the ground is dry enough to work. Most people have an idea that the stirring of the soil is primarily in order to kill weeds, but there is equal need of it where no weeds are present. The roots of plants require air as well as moisture, and frequent stirring of the surface soil admits the air and at the same time conserves moisture. Shallow cultivation during dry weather forms what is known as a soil mulch, preventing the escape of moisture. Very often shallow cultivation during dry weather is more effective than irrigation.

Watering
Artificial watering, if properly applied, will prove a decided advantage during dry periods, but may prove an injury if not properly handled. Frequent light sprinkling of the garden is injurious. The proper method is to soak the soil thoroughly about once each week, preferably during the evening, and then loosen the surface by cultivation the following morning or as soon as the soil is dry enough to work. No more water should be applied until absolutely necessary; then another soaking should be given. On a small scale the water may be applied by means of a sprinkling can. Where available, a garden hose is effective, and overhead sprinkler systems are frequently employed to advantage. Perhaps the best method for applying the water is to open slight furrows alongside the rows of plants and allow the water to flow gently along these furrows.
After the water has all soaked into the soil the wet earth in the furrows should be covered with dry soil, to prevent baking. Where seeds are to be sown during a period of drought a slight furrow may be opened and filled with water; then, after the water has soaked into the soil, the seeds may be sown and covered with dry earth. This method will insure a good stand of plants, as the moisture feeds upward in the soil, like the oil in a lamp wick.
