How many trusses per tomato plant?

[swee'pea99]

I've always worked on the basis that you should stop the plant after five or at most six trusses, to give all the fruit a chance to ripen, but a couple of years ago when we had that hot summer I was left thinking the plant would have managed more - it ran out long before the end of the season.

Now this year it's all gone a bit bonkers. The plants are absolutely loving all this sunshine, and they're growing like billy-o. One has separated into two main stems - both are flourishing, with four trusses on each. That's eight. And we've only just hit July. The other has also divided into two main stems, one of which I discovered this morning has now taken it on itself to divide again. So that plant now has three 'main steams', with a toal of eight trusses between them.

Now, should I stop/cut off all main stems and leave the eight-per-plant to mature? Or even reduce, back to six? Cutting back to six just feels like something I might well regret if we do have a long hot summer, which seems to be on the cards. It seems awful early to be cutting off thriving main stems, but should I bite the bullet?

Any advice appreciated.

I hate you!
About the tomatoes, I would just let them grow without interfering, apart from taking the non fruiting side shoots off.
Trim them off to basics middle of August.
Tomatoes need not only heat, but light too.
Here in Scotland the tomatoes that haven't ripened by mid August won't have a chance to finish ripening, because our days get shorter.
Maybe in England you get a couple of weeks extra?
