Care of Tomato Plants in high temperatures 16 July 2022 at 7:51AM in Greenfingered MoneySaving 4 replies 264 views

My tomatoes are planted in pots and situated in a very sunny spot.  It's predicted to be 38 - 40 degrees in my area and I won't be leaving the house!  Should I move my tomato plants into a shadier area for these days and am I OK to leave them sitting in trays of water?  Thank you.

My tomatoes are always in trays of water but I will open the greenhouse door.  There is no way I could move mine, they are 4 feet high and tied up to the greenhouse structure.

Good call! Mine have got a bit burnt in the last few days so will definitely leave the doors open for them

I'd just watch them carefully. Too much water in the pot and the roots could boil.
Perhaps errect a barrier of foil round the pots to reflect the heat from the roots. You can buy cheap shading if necessary.
I wouldn't leave them in standing water but fill the trays each night.

Thank you.  (Mine aren't in a greenhouse.)  Experimented with water trays for a short period today - will check their health this morning!
