I had two swiss chard plants over-winter this year, first time that’s ever happened for me. Someone else I know also had chard over-winter and said the leaves were tough, but our plants were treated to a bunny pruning before the electric netting went on, and the pruning must have helped, because our leaves were perfectly fine.
Not ever having plants live through the winter before, I was surprised when they bolted, geting to a good 5′ or so in height. Curious, I left them for a while to see what they’d do before throwing them in the compost. Could have collected seed, but I didn’t.
So, the reason this happened is that swiss chard is a biennial and goes to seed the second year. Apparently, I yanked it too soon though, because the small inner leaves are supposed to still be tender and delicious. I should have tasted them before I assumed they’d be bitter because the plant bolted. I finally decided to get them out of there to give the new chard plants room to grow.
Anyone else have anything over-winter, since winter was so mild this year?
