See, if they hadn't had the snow blanket it would have made more sense that they died..Agreed, but during our mini ice age they were buried under about four inches of ice/snow and -6 F temps for almost a week. We also lost a lot of ornamental plants during that time. Our average lows are mid 20 F.
I believe it was more the weight of the snow and ice that mashed them down and broke all the stems up. The mustard greens came back from the center to produce, but the cabbage had golf ball size heads forming that got beat down and turned brown and died. The turnips where beat down like the mustard greens but they just never put on many new leaves after the thaw and just sat there. The four cabbage that survived were runts that hadn't started making heads yet. Might get to harvest them a little small if the heat doesn't get them first.Maybe it was more the drastic change from Texas hot to colder than ice that killed them.
I hope we get one peach at least. The trees are young, so if they produce no fruit, they'll be able to grow stronger. I've learned that it may take about 2 weeks until the full effects of the frost are known.With little frost and a light freeze it may only effect the upper portions of the tree. If at all. Hope they all make a lot of peaches for you.
