I found a few turnips in the garden that have been there since they were planted last summer. Somehow they made it through a Connecticut winter. They appear to be fine. Are they still edible?
Yes, they are. In fact, this was an old way of keeping carrots, turnips and other fairly hardy root vegetables through the winter - by leaving them in the ground where they would be insulated from most of the cold weather by soil and snow.
I have planted turnips and radish from seed. The leaves of both are like lace, with small holes throughout the leaves. Can you tell me what the problem is and how to treat it?
There are several kinds of caterpillars that causes that kind of damage. Without seeing the bug, I cannot ID it. But, the standard treatment for almost any caterpillars is Bacillus thuringiensis, also known as Bt. You can also try neem oil. This is usually effective on those kinds of pests.

I am asking for advice on my turnips. They are growing well but the tops on them seem to grow too much. The turnips are about 25-40mm, but the tops are about 10 to 12 inches tall, and I don't want them to go to seed. I heard that if you cut the tops down or even walk on the tops that it helps the turnips to grow better. I would like to know if that is right. Any advice would be most helpful. Thank you.
Removing or damaging the tops is not likely to help. The soil most likely either lacks phosphorous or has too much nitrogen. Both conditions result in large healthy tops with small, stunted roots. Try adding in a phosphorous rich fertilizer like bone meal to the soil to help bring it back into balance.
Is it too early to plant turnips, mustard and kale in southern G? It is still in the mid to upper 90's. I want a good start on them before frost.
These are good plants for the fall garden. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/turnip/turnips-growing.htm
Can I cut the tops of my turnip leaves for turnip greens now, and will they still grow the turnip? Mine came up early.
If you want to harvest them for turnip greens, you can. If you harvest the whole top, the root will not develop well. If you leave the tops on, it should still develop a turnip root.
