Always water transplants to settle soil around roots. Set tall plants deeper than they grew originally. To control weeds, cultivate frequently but shallowly. Chemical weed killers are not usually recommended for home gardens. Before using, get full information on how to use and what crop to use them on.
Water is essential for a top-notch garden.
Light, frequent irrigation helps only during seed germination. Overhead irrigation, especially late in the afternoon, is likely to spread certain diseases. If you use overhead irrigation, do so earlier in the day so plants can dry before night. Chemical fungicides, such as chlorothalonil and maneb, may be used to control some common leaf diseases of tomatoes, squash, cucumbers, and cantaloupes. If the garden is heavily infested with nematodes, either move the garden or treat the soil with recommended chemical.
