I promised an update...
The winter gardening was mostly a failure. I managed to get 4 Romaine and 2 beet seedlings from all my work. I probably did it wrong, and I may try again next year. If I do, I’ll let you all know what happens.
I was told, here in central TX, to plant those winter underground veggies in September, so I’m going to try it.
Try varieties that are cold tolerant. They often have names like Artic King, Winter density, etc.
Once temps get to freezing, it is very important to protect the winter garden. I use milk jugs of water around three edges of the winter patch, surounded by styrofoam, and covered with row covers, straw, and light weight styro foam mattress when needed.
I would think that Veggies like carrots and beets need to be well established and almost ready for harvest, as they won’t grow much during the cold weahter. I would plant them in the fall, and consider leaving them in the garden to be more of an inground storage rather than growth.
Keep us posted on further efforts. Thanks for the update.
