@killyourfm it really is a balance, especially with tomatoes they'll split if you water them too much too quickly, but when it's that hot out sometimes you really do just have to drench everything to keep them alive. Depending on how long the heat wave lasts and how much rain you get you could soak them in bursts a few times a day to make sure it's soaked enough to pull in the water, but don't keep the ground permanently saturated or you can also cause damage.
