Semi-determinate tomatoes

Mark Pelican (remember him from the dark side?) says:-

Semi-Determinate: Allow all the sideshoots on the main vine to grow (secondary vines) but remove all sideshoots on the secondary vines. Each vine will set a small number of trusses (two or three) and , like Indeterminate cultivars, the fruit will ripen gradually over the season and will have to be removed before the first frost kills the plant. https://myvegpatch.co.uk/tomatoes-determ...arvesting/

Have fun with that!! Great looking plants though.

No, dont remember Mark Pelican, although I wasn't very active on there. 
Maybe it's a bit too late for those instructions but I might have a go at thinning them out. Should've asked earlier.

PS thanks for the link.
