Hmmmm.... I thought they (Crimson Crush at least) were cordon rather than bush and grow them as such....
I think you are right, but I let the outdoor plot tomatoes go their own way for the most of the time. I don’t always get there as often as I should to keep them side shooted
Mine produced a decent sized plant with several branches and a ton of fruit. The seeds are pretty pricy so I was happy to let single plants hog a bit of room, if they were going to pay me back for it.
Crimson Blush produced fewer but larger fruits. They were also pretty ungainly specimens, but did not take up too much space. I make mini ‘bean’ trenches over the winter, plant the tomatoes on top and them usually have something sprawling around at their feet. Last year it was courgettes and pumpkins, which I trained to run along the fronts of these areas. Messy and untidy gardening, but productive
