I have grown tomatoes in my greenhouse for the past 2 years and on neither occasion have they turned red. I have used different types each year. Can anybody advise what I am doing wrong. I water and feed them and take out the shoots and there are plenty of tomatoes on them
Does it get too hot in there? When it's too hot they stop growing.
If the temperature is above 30C or below 12C for a period of time they won't ripen until temperatures fall to between 12c and 30c.
If yours aren't ripening then I can only think that by the time your tomatoes are fully formed temperatures are too low for them to ripen.
Some varieties take a lot longer to ripen than others.
What variety are you growing?
I start mine from seed in the 1st week of March.
This year Rosella was the first to start to ripen about 3 weeks ago.
Now I have a few Shirley that are ripe.
Rose de Berne are still all green, but I usually start harvesting them around mid-August.
Wisdom is not putting it in a fruit salad.
How long are you allowing for your tomatoes to ripen?
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
If you're in a very hot area, and they're inside, it's important they have plenty of ventilation too, because it inhibits them if too hot, as already said, but it sounds as if they're doing ok. If you're in a much colder part of the country, it'll take them longer to start ripening, so you may find they'll need some help later in the year.
As @Dovefromabove says, one they're turning a paler green, they'll keep ripening as long as they have enough warmth, so don't worry too much just now if they're otherwise healthy.
If you have a photo or two, that can also help with further advice
I live in west central Scotland - not where that photo is...
