tomatoes summary

Start feeding when the first fruit have set (i.e. you can see the first tiny tomatoes forming), use a specific Tomato food thats high in Potash and follow the instructions (usuallay feed once or twice a week, but follow the dilution rates).

Help the toms to pollinate themselves, just give the plants a gentle tap or shake each time you water. If you grow them on a support frame just give it a few taps, that’s usually enough to shake the flowers causing them to self pollinate.

Nip out the tops when they reach the top of your support, in my greenhouse I'm up to 8 trusses and have just stopped them. With your tomatoes I'd stop them a month before your first average frost date, so that might mean in early Sept you are nipping out the tops (depends on your location) before they hit the roof. The idea is to leave enough time for the top truss to ripen before the first frosts.

Also depending on your tomato variety you will probably need to side shoot them, are you doing that?

 

Scotty; It does depend on the variety you are growing, most people with greenhouse grow the normal 'cordon type' (Moneymaker, Golden Sunrise, Gardeners Delight etc) and these need to be trained (or sideshooted or pruned - people call it different things), its all about making sure the plant puts all its energy into developing fruit rather than branches & leaves.

The other tomato type is the 'bush' type (varieties like tumbling tom), you just let these do their own thing, no sideshooting is needed.

Heres a good explanation of how to sideshoot:
