Q.Beef Tomatoes
I am growing some Italian beef tomatoes (Cuore di Bue Albenga Alto) for the first time in growbags in my south facing greenhouse and outside beside a south facing wall in Kent. They have all started to set with trusses of up to 20 tomatoes per truss, with the third trusses in the greenhouse plants at about 3ft high. The outside plants are far more squat. Should I reduce the number of tomatoes per truss on either the inside or outside plants or should I just attempt to go for a bumper crop? Thanks in advance for your advice. Regards

It is ok to leave them. At this point, it will handle what it will have on the vine. Usually, the thinning should be done before fruit set, and will have more to do with removing extra vegetative growth than flowering growth. At this point, whatever is on the plant can be supported.
Though a little different, I have my tomatoes indoors. When space is an issue, you can pinch the tops off of the growing shoots. They will respond by growing bushier. Though this is a height control method, pinching the very tips of the vines can also help increase productivity.
