As a general rule of thumb, your garden needs about an inch or two of thorough, infrequent watering, once a week. This will give you a good baseline for weekly watering. Giving them a light surface watering every night or every other night isn't as healthy as a thorough weekly watering, which encourages roots to grow deeper rather than shallow .
However, how often you should water your garden depends on your climate, the plants you're growing, and your recent weather. There's no one-size-fits-all guideline, but these tips will help you tune in to your gardens' needs so can keep your outdoor plants happy and healthy.
For example, most vegetable need about 1 to 2 inches of water each week. If your plants are in the ground (versus a pot), the general rule is that plants need one inch of water per week.
