Try putting them in a brown paper bag on top of the fridge. Works well with avocadoes too..
put in any widow or even in a drawer they will soon turn red.
If they are outside, you may have to bring them in! You can grow tomatoes year-round inside the house! Just use pots and keep them in a sunny window, that isn't too drafty. Go ahead and pick the green ones you have now, and put them in the window.
Weve just finished our home grown tomartoes just put the green ones on a window cill they'll soon go red.
Tomoates, tomatoes, tomatoes.running out of control. Well now is the time to stop watering, and even pinch back new flowers. I even thin out the thick mass of foliage, to let more sunlight in while there is sun! Just ripen what you have on now because any new tomatoes will not have time to ripen and tend to rob existing tomatoes of flavor! Sungold cherry tomatoes are the most popular again this year.

Onions and garlic can be planted now, but garlic will be a year before it can be harvested. Potatoes and carrots will keep in the ground for as long as you want to keep them there.
stick them in brown paper bag and put them in airing cupboard
window sill is your best bet, an occasional occurance of a fruit fly will indicate if the tomato is ripening well.
they grow the seed's and sow the seed's
leave them next to window in the sun they will ripen beautifully
wrap them one at a time in any paper and put them in a egg try and just put them in the dark for a couple off days they will ripen and stay firm as well
try setting them in a window sill and leaving them for a while, turn them daily so the sun will hit them on all sides. should work out ok as long as the window sill gets plenty of sunshine.
Pick them and place them in the dark, preferably a brown paper bag.
My brother brought his in just before a frost. He laid them single layer in an unheated garage, probably 50 degrees. Just leave them alone and check often. They ate their last fresh tomato on Christmas day.
