I know it gets very tempting with the first ones - but after that I'm in no hurry to remove the next ones until they are really ripe, cos they speed up the ripening of the next lot, and so on

Well I have put quite a few banana skins inside the greenhouse hanging around and so fat (after a few days) it hasn't made any difference.

[Headgardener22]

I've heard that putting banana skins in the greenhouse will stop any more fruit setting.

What's the hurry? Last year I was picking ripe tomatoes in late November and they still tasted better than shop-bought ones

[mumofstig]

I've heard that putting banana skins in the greenhouse will stop any more fruit setting.

Speaking from experience - it doesn't

[hubballi]

Why do I always get conflicting advice here  banana skins good or bad ?

He's heard that - but my experience is that they don't stop more fruit setting.

I found they did help to ripen fruit that was nearly ripe already

Banana skins give off the same ripening 'gases' that some other fruit do, so chuck some around Hubbali, and don't worry!

We're more worried about blight than getting anything else, so you're very lucky to have anything to ripen anyway!

[hubballi]

It's ok, I keep my greenhouse shut so no blight.

How do the bees get in then?

And you might have problems with mildew because the air is still and damp.

Well, I do not know if it is just nature taking its course or if the nana skins are doing their work BUT I have two tomatoes finally on the turn. 

[hubballi]

Must have about 10 skins in now but they haven't made a blind bit if difference. It must be an old wives tale.

[mobilekat]

Tomatoes will only ripen if they are developed enough to turn ripe.

If they are still small green bullets they have to finish growing up before they can turn red.

Etylene has been proven to ripen tomatoes- otherwise why would some farmers spray it onto under ripe tomatoes to get them to ripen while on their way to the supermarket.

But as has already been said it only works if the tomatoes are close to turning!

Just relax and let nature do its thing, as the summer has been dull, and as you have told us you have a garden with a high wall, and debris netting over the greenhouse, and the green house is over crowded all of this things will slow ripening.
 

[Springlands]

Mine have started to ripen at last - have had two so far - so whether it was the bananas skins or whether or not  nature took its course it is hard to say. It has definitely been a difficult growing season.

[DD.]

It must be an old wives tale.

Don't be so dismissive when everyone is trying to help you. I'll underline what mobile mobilkat says, it's scientifically proven that ethylene gas will hasten ripening and as others have said the tomatoes must have reached their full size.

I am happy to report that the Tigerella toms are ripening very well
