This year we planted fullsize tomato plants and cherry toomatoes. The cherry tomatoes were a spectacular success. We picked 900. (Last year we got 489.) And they were delicious. The fullsize ones were a disappointment: 23 (we had 40 last year). At season-end I finally started looking online for advice on how to prune tomatoes. I discovered that there IS excellent advice, and I have not nearly been following it. It's also obvious, now, that I should not plant cherry tomato plants right next to fullsize plants, for the sprawling cherry tomato growths overwhelmed the biggies.
While reading advice about pruning, I became certain that cherry tomatoes should not be pruned the same as big ones. If I did that, I would lose about 80 percent of my cherry crop! So I was happy to find the following advice about pruning cherry tomatoes, which suggests I was doing just about the right thing for them:
Pruning and staking increases earliness to fruiting, at the expense of yield.
Earliness to fruiting, Hm? Next year, I might try pruning ONE cherry tomato plant.
