If one’s going to take a vacation, last week was the week to do it, and that’s just what we did.
Hot and dry was the order of the day last week, just the way tomatoes like it. You will have to take care now with the watering; be careful that you don’t drown them by over-watering after this heat wave. In doing so you can cause them to split and develop blossom end rot.
Just be a little sparing with the H20; and hold off, if you see rain in the next day’s forecast.
Remove the sucker too; no sense letting something grow that only uses up moisture and produces zero benefits.
