Set tall plants deeper in the ground than they grew originally. To control weeds, use a mulch. Deep cultivation after plants are older will do more damage than good. Chemical weed killers are not usually recommended for home gardens. Before using a weed control product, get full information on how to use it and what crop it should be used on.
Water is essential for a top-notch garden.
Light, frequent irrigation helps only during the period of seed germination. Overhead irrigation, especially late in the afternoon, is likely to spread certain foliage diseases. If you use overhead irrigation, do so earlier in the day so plants can dry before night. Chemical fungicides 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 heat the soil through a process called soil solarization.
