Beat the heat

Gad zooks! It’s supposed to be a hot one this weekend, with temps topping 90. You can seek shelter in air-conditioned comfort, take an ice bath or hide out in a movie theater watching “Transformers” over and over, but what can your plants do? Here are some ways to help your garden beat the heat:

Water. Early morning is best, because there’s less loss to evaporation. But if you can’t water early, water in the evening, once it’s cooled off a bit. (Nighttime watering isn’t the best because it can encourage plant pests and diseases.) And remember, water thoroughly rather than often. Set the sprinkler or soaker hose and leave it go for a while. Watering with a watering can will likely leave your plants thirsty.

Mulch. If you haven’t mulched already, add an inch or two of organic material (hay, straw, shredded leaves, partially completed compost, etc.) to your garden beds, around trees and shrubs, even in your containers. Mulch helps hold soil moisture in and keep soil temperatures down.

Move. Your potted plants, that is. Group containers together in the shade, at least during the hottest part of the day. That will help keep them from wilting.

Be nice to your grass. Continue to water your grass at least once a week, even if it’s starting to turn brown. If you give up and stop watering completely, you can permanently damage the little grass plants. If your grass is drying out and browning, stay off it as much as you can.

Keep chemicals at bay. Plants (including grass plants) are likely to be stressed by the hot, dry weather, so it’s not the best time to fertilize or treat for insects. Wait until the weather cools.

Don’t panic. At the end of a really hot, dry day your plants may look wilted, but they’ll likely survive. Just water when they’re dry — and wait for cooler weather.

What do you do for your plants when it’s this hot?

just wanted to add that some cities have watering restrictions that advise to avoid watering from 4-10pm during the heaviest water use period. so if watering in the evenings, you might want to wait till a little later.

also, i read somewhere that when its super dry out like it is now, letting your grass grow a bit taller before mowing helps the grass hold onto more moisture. and setting your mower height a bit taller helps too. i’m not certain if this is true, but my taller lawn seems to be doing much better compared to my neighbors super short cut.

Great advice, Laura. Letting your grass grow a little longer helps keep the roots of the plants cooler, which, in turn, helps them hold water in a bit longer.

Watering at night,however, can lead to disease, because plants (including grass plants) don’t have a chance to dry off over night. I water at night some times, but try not to make a habit of it, especially for plants that are prone to fungal disease (phlox, etc.)_
