How often to water new shrubs/plants in 90 degree heat?

I have a new Rhododendron and a new Hydrangea which were wilted when I got home today. Today was about 90 degrees. I watered them well, and they perked back up after an hour. Tomorrow is supposed to be even hotter. Should I soak them in the morning again? Is it ok to wait until shrubs/plants begin to sag/wilt before watering them?

How often to water new shrubs/plants in 90 degree heat?
Water them early in the morning before the sun comes out. Then water them again in the evening after the sun goes down. Don't drown the plants at either watering. Just give them a nice gentle drink of water. Never water them in the middle of the day when it's so hot, as the sun will evaporate the water, thus drying out the plants. Don't wait for the plants/shrubs wilt, rather keep the soil moist at all times.
Reply:Always, always, always water your shrubs before the sun hits them. Water them early in the a.m. so they can withstand the heat throughout the day. Don't wait until they wilt. This method works for my shrubs and flowers. Good luck!
Reply:Make a mounded edge of dirt around the shrubs about 6-8 inches high about 15-20 inches out from the shrub- creates a pool for watering so it doesn't run off and cover the base of the shrub about 15-20 inches around with pine bark mulch that will help hold in the moisture- water before 6 am or after 6pm.
Reply:In addition to laying down mulch and watering my new plants every morning, I also cover them until established. A plastic nursery pot works quite well. For larger plants, I use an old garbage can with air holes poked through the top.



Also, if the temps are just brutal, a real slick trick is to fill up a gallon jug with water, poke a small hole in the base with a nail, and set it somewhere above the planting hole, mid day. Voila! cheap drip irrigation to keep your plant happy through the hottest part of the day.
Reply:water every day in this heat, just don't over do it because you can deplete the ground of nutrients.





Try watering every other day, early in the morning, but make sure you water if they look wilted
Reply:water them in the morning or the evening when it is still cool and i believe it is one inch daily while it is hot and 1 inch every other day while it is average temp use a tuna can to measure when its full you have given the plant 1 inch of water don't quote me on this
Reply:Only water early, early in the day, or after the sun goes down. It's just a waste during the hotter parts of the day. Is there a way to create some partial shade so the sun doesn't beat down on them so bad (like a black net or such that doesn't sit on the plants but above them.)
Reply:well for how often you should water, being there new and depending on the temperature its best to check the soil with ur finger by sticking it in as far as u can and if little or no moisture than they need watered, but if temps are really hot evening time or early morning, never water plants in the sun
