In the hot drought-oriented summers of the US Southeast, lawns and plants could easily turn brown and die off without extra watering. However, an average of 30% of that water evaporates off without actually making it into the ground, and in desert climates like the Southwest, that loss can jump up to 50%! So if you have to water your plants, make sure you’re getting the most out of it with a few tips.
1. Try to water early in the morning or late in the evening during cooler times of the day when the sun’s not out in full force. You’ll cut your evaporation losses substantially, as well as your water bill!
2. Water the plant’s roots, not the foliage. Not only will water tend to evaporate off the leaves more easily, but it also increases your risks for pests and disease. You can water the roots more deeply with that water you used to waste on the leaves and hence less often!
3. This seems like a no-brainer, but make sure you are actually watering your plants, and not the sidewalk or concrete! Check the range of your automatic sprinkler system, or if you water manually, never leave the hose running unattended where it might end up stuck on the driveway and running water straight into the drain.
