Couple that with record-high tempera- tures, gardeners need to be aware of water usage and con- servation this gardening season,” Hillock said. “Some cities implement water conservation measures to conserve water during the hot summer months, so proper, efficient watering is important.” When the temperature is high and the humidity is low, plants need plenty of water. It’s healthier for plants to be wa- tered deeply, but infrequently. Generally, 1 inch of water per week is recommended, preferably in one application, but that isn’t always achievable because the soil does not absorb the water as fast as it is being distributed. Hillock said to avoid runoff, watering may need to be done in stages. Irrigate to the point of puddling, then turn the wa- ter off and let it soak in for several hours. Then try to put the rest of the water on later that day or the next day. In this heat, and depending on the soil type, gardeners may have to apply 2 to 3 inches per week. oun ae sbi attaiat iba ST = “allowing the water to soak into the ground and letting the Algae is a normal part of ponds, but too much algae can be a bad thing.
