Thanks, Emily, for that tip in case of late freeze. I'm hoping we've had our last cold spell for the winter, but we'll see what Mother Nature thinks. We seldom see eye to eye!
Karen, this is the first time I tried those containers and so far I'm happy with them, although I can see how it would be a problem in areas where winter lasts longer than here. I've popped the top partially open to give those babies some head room and I just hope they'll be good to go in the ground in a couple of weeks.
I didn't use any milk jugs this year, sticking strictly with the 2-liter soda bottles and various other containers like the big lettuce and bing cherry containers. The soda bottles are much easier to work with and I like being able to see what the root development is, which I can't do very well with the milk jugs.
