Six Tips For Watering Your Garden
- Focus on the root zone. Remember that it’s the roots that need access to water, not the leaves. Wetting the foliage is a waste of water and can promote the spread of disease.
- Water only when needed. Automatic Watering Timers are especially useful; just make sure to watch the weather, and reduce frequency when rainfall is abundant. Too much moisture can be just as damaging to plants as too little.
- Water deeply and thoroughly. Lawns and annuals concentrate their roots in the top 6″ of soil; for perennials, shrubs and trees, it’s the top 12″. In heavy soil, it may take hours for water to percolate down 6-12″. Use your finger or a shovel to check the progress.
- Water in the morning. If you do get moisture on the leaves, this gives them time to dry out. It’s much more difficult for plant diseases to get a foothold when the foliage is dry.
- Mulch everything. Mulch reduces surface runoff and slows evaporation from the soil.
- Use the right tool. For efficient watering at the root zone, use a soaker hose or an even more precise drip irrigation system instead of a sprinkler.
