If you haven’t give much consideration to the way you water, here are five suggestions that will save you money on your water bill by using water wisely and efficiently. If you’d like to read four additional tips, check out the source for this blog on Popular Mechanics.
1. Choose the Right Tool
2. Water at Widely Spaced Intervals
With your lawn and perennials, it’s better to give them larger amounts of water at longer intervals than it is to apply small amounts of water frequently. That’s because shallow watering encourages shallow rooting. In very hot weather, a ballpark range for watering is every other day for perennials and every three to four days for shrubs. Again, make sure to monitor the soil moisture.
Water annuals and container plants as needed. Since container plants can’t draw moisture from surrounding soil, it’s crucial that their soil remain moist (but not wet).
3. Water in the Morning
If you water while it’s (relatively) cool outside, water can soak in before it evaporates on the surface. And if you do it in the morning, that helps the plant to take up the water during the day. Watering at dusk or even during early evening is OK, but you run the risk of fungus formation, because these organisms love dark and damp places. Plus, the darkness can make it hard to see what you’re doing (and, as noted, precision counts even when watering your plants).
4. Don’t Waste Water
Don’t soak the plant’s foliage; it does little good. And don’t apply water outside a shrub’s or a perennial’s root zone. A shrub’s root zone is roughly 1 to 3 times the diameter of its canopy, and keeping the water inside this radius will allow it to soak down to where the plant’s roots can reach it.
If you see water puddling or running off, stop; let the water soak in before resuming. Likewise, water that runs off your lawn or off the top of a flower bed onto paved surfaces does no good. The same applies to running lawn sprinklers: Water your lawn, not the side of your house or the driveway.
5. Use Cool Water
Don’t use a hose that’s been coiled up, filled with water and sitting in the sun all day. That coiled hose can act like a water heater, and hot water stresses sensitive plants. Store your hose in the shade. If you can’t, at least run out the heated water before giving your plants a drink.
