I have money maker, they are in the glass house and have been growing quite prolifically since October (reaching the roof). This year for the 1st time not many flowers actually germinated, those that did have stayed green on the vine (some have been there for 2 months). I have had a look online for the reasons and I'm sure none of those mentioned apply to me!
I have had some on the window ledge and some in a brown paper bag (with an apple) for a week and they are still green. Any ideas?
I want to make tomato sauce not green tomato chutney.
are you keeping the water up to them? Try a bit of potash or wood ash that has not been rained upon. If all else fails, try nail polish!
Is your greenhouse heated? Its the variation between minimum and maximum temperatures. Too hot and too cold and they stop ripening If your spring has been anything like ours, we were getting very cold nights right up until Christmas, and the few hot days can make a glass house temperature soar. If the weather settles down to a steady row of warm nights and not too hot days, then they will ripen. Nipping out the leaders so they don't try to set any more fruit may help, but of course this will be to the detriment to the later harvest......As with most things in the garden - you just can't win!
The watering is on automatic timer, 1/2 an hour in the morning and 1/2 an hour at night (too much or too little?) and they are growing prolifically! The glass house is not heated and I believe the temp is ok neither too hot or cold, they are growing in compost and I have added other fert. But maybe I could try extra potash! Also you are right with gardening sometimes you can't win.
Just read online it can take 3 weeks to 3 months to ripen off vine (last year they ripened on the window ledge in less than a week) This informant said they don't need light ie not on window ledge but around 15 degrees is best and a darker place. Might try everything!
