Mealy Tomatoes: Heat, Water and Storage
The short answer
Mealy tomatoes usually come from growing conditions or the fridge. Mississippi State Extension lists high nitrogen, low potassium, low calcium, too much water, too much heat and certain varieties as causes. University of Arkansas Extension says chilling below about 55°F gives a mealy texture. Hold whole fruit at room temperature.
Why are my tomatoes mealy?
Mississippi State names several causes, from high nitrogen to too much water. It also says warm conditions cause softness. University of Minnesota Extension notes tomatoes love heat, yet extreme heat affects fruit. See the effects of environmental stresses on weed plants and cannabis heat stress.
Does refrigeration make tomatoes mealy?
Yes. University of Arkansas Extension says below about 55°F, flavor enzymes are inhibited and cell membranes break down. Mississippi State Extension says refrigeration destroys flavor. Very ripe fruit can be chilled briefly, then warmed to room temperature.
How do you pick tomatoes for better texture?
University of Minnesota Extension says to harvest at usable size and color. Mature green fruit often ripens well indoors at room temperature, where warmth matters more than light. Timing ideas are in is your marijuana ready for harvest.
