It’s the tomato blossoms that suffer most during extreme heat – a heat wave will not likely be fatal for the plants, especially if you can keep them watered and tomato fruit already on the vine will likely be OK, too. Help out the blossoms by providing shade - use these tips.
Cool midsummer temperatures can inhibit phosphorus uptake (leading to fewer blossoms and purple leaves) and prevent tomato blossom set. To offset the problem, set down black plastic around plants. You’ll trap heat in the ground so that it radiates up to plants, and as an extra bonus, you’ll keep weeds down, too.
Too much rain can water log tomatoes – effectively drowning the roots by blocking air pockets – and allow diseases like blight and wilt to flourish. You cannot stop the rain. But you can spread plastic ground cover around tomatoes that will shed that excess water off plants and into the rows.
Tomatoes need an inch of water a week and up to 3 inches if it’s particularly hot. (That includes rainfall). Offset drought with the tomato watering technique that works best for you.
