How Often Should I Water My Flower & Vegetable Garden?

Vegetable gardens need consistent moisture.

Consistent Moisture

All vegetables need consistent, even moisture to thrive. Water vegetable gardens at least weekly in dry conditions to keep the soil moist but not soggy. Flower gardens vary in the amount of moisture they need. Many perennials need little water, once established, while roses, hydrangeas and most annuals need consistent moisture.

Varied Growing Situations

Native plants and perennials are drought-tolerant and some even prefer to stay on the dry side. Other perennials, though, need weekly deep watering to thrive. Water clay soils less frequently and sandy soils more frequently. Additionally, water more often during very hot or windy conditions.

Bottom Line

Always keep vegetable gardens moist and apply black plastic, weed-free straw or grass clipping mulch to conserve moisture. Water flower gardens based on individual plants' needs. Group plants together accordingly. Don't plant thirsty plants with drought-resistant plants.
