We live about 4 miles due south of Murchison - just S of Lake Athens.
We have two tomato plants that were put in the ground on Feb 25 (inside wall-o-waters). Since then: it got to 29 for a couple of hours on 2/29, we got 1/2" of sleet followed by a low of 22 on 3/2, and finally (we hope) the 35 degree low on 4/15. The freezes in Feb and March weren't a problem, but by April, the plants were protruding about 5" above their walls-o-water. So, the day before that freeze, I put a 3cf mulch bag over the top of each w-o-w. This bag was removed by 10am that morning. Both plants are looking fine - even at the top. Here's a photo of the larger one.

We've used w-o-w's for several years - both here and when we lived in Ft Worth. No plant losses that I recall. The ones we're currently using are made from reddish plastic.
