Using Polythene to ripen tomatoes
I take it you have some nice big green tomatoes under your polythene cloche? Tomatoes certainly need lots of light preferably sunlight to ripen off nicely so I would suggest you remove the polythene if you are in a hurry. They will ripen eventually under the polythene because commercially they are grown that way in poly tunnels.
They will also require more water as it will probably be hot under polythene.
Here at Stephanie’s Kitchen Garden they are slow to ripen this year so enjoy your tomatoes when you eventually get them!
