What's happening to my turnips?
I planted turnip over two months ago in trays. Initially outside but they were later transferred to a heated greenhouse following advice from helpful people on here. I can barely see bulbs on just a few of the plants so I’m not too sure what is going on. I hope that they all have large bulbs under the surface but would be surprised to find this has happened.
I always assumed that the turnips will be ready to be harvested when the leaves die, as they do with potato plants, but they show no signs of doing this. Youtube videos show turnips being harvested will all the leaves looking a healthy green.
I’m newish to growing veg. and I’m just getting more and more confused about what, if anything, to do. Any advice gratefully received.
