It might make us feel better and be more comfortable, but for plants it can be deadly. Plants need and love moisture. Obviously that is why there are so few plants in the arid regions of the world compared to more tropical environments. With temperatures reaching the high one teens this weekend it is imperative that you are providing enough moisture to plants and helping them stay as moist as possible. Watering deeply so the soil doesn’t dry out as quickly is the first step, adding a layer of of organic compost, mulch, or bark under and around plants will keep the soil moist longer and provide some relief- especially to plants that are not quite as well suited to the heat ( roses, fruit trees, vegetable and flower gardens…)
Be sure your irrigation system is delivering water to the right places and heads and emitters are functioning properly. Your irrigation schedule should be increased again when it’s over 110 even if you had already adjusted for summer watering or better yet just cycle the system manually a couple of times during extreme heat events. It is better to water in the very early morning hours to minimize evaporation and wind effect, morning watering is also preferable to night watering to prevent fungus and disease -especially when watering turf. If you suspect your irrigation system is not working properly call us we can arrange an evaluation and make recommendations how your system might operate more effectively.
This is also a great time to make sure the trunks of young and or smooth barked trees are protected from the sun. Paint or wrap ficus, ash, citrus, stone fruits until they grow a canopy
of branches and leaves that will protect the trunk. This is not a great time to prune most plants-consult with us or the folks at Integrity Tree Service before you do any major pruning projects during hot weather.
