How often should I water my garden?
General Guidelines
The ideal is 1 inch of water per week, including rainfall. In hot, sunny weather, you may need 2 inches. Sandy soil drains fast and may need more frequent watering; clay soil holds water longer. Container plants dry out faster and often need daily watering in summer.
Water in the morning if possible, so leaves dry before evening and fungal diseases are less likely. Water at the base of plants, not the leaves.
- Check soil moisture by digging 2–3 inches down.
- If dry, water; if moist, wait.
- Use a rain gauge or tuna can to measure 1 inch.
- Mulch to retain moisture and reduce watering frequency.
- Drip irrigation or soaker hoses are efficient.
Signs of Under- and Overwatering
Wilting during the day can be normal in heat, but if plants are wilted in the morning, they need water. Yellowing leaves, stunted growth, and root rot are signs of overwatering. Stick your finger in the soil to judge.
Newly planted seeds and seedlings need consistent moisture, so water lightly daily until they establish. Established plants are more drought-tolerant.
Common mistakes
- Watering a little every day, which encourages shallow roots.
- Watering at night, which can promote fungal diseases.
- Assuming rain has watered enough without checking the soil.
