I’ve been getting lots of questions about tomatoes splitting.
This usually happens after a heavy rain. The plant takes up the water which is more than the tomato itself can handle and then the skin splits. This is different than cracking, which happens a lot on the tops of bigger tomatoes. splitting is mot often along the length of the fruit.
Some varieties are more prone to this than others. ‘Sungold’ is an orange cherry that is notorious for splitting, but the flavor is so prized the splitting is overlooked, at least in my garden. Thin skinned varieties, like many of the heirlooms I grow, are also going to split and most do this after already ripening. It’s no big deal to me, I’ll just harvest the tomato and leave it on the windowsill until completely ripe. It’s not the sun on the windowsill that ripens them, they just need a little more time and that’s a place I won’t forget about them. When left on the vine, pests can get to them and sometimes they will also start to get moldy and gross.
Keeping plants watered properly during a dry spell will help avert splitting. Mulching with a thick layer of straw will help too. Varieties with thicker skins will also fight off the problem. I started poking around the Internet looking for resistant varieties and found ‘Sungold’ on a list. It will split when there’s a chance of rain!
It’s nothing I worry about, grow a few different varieties, some will split, other’s wont.
