    Ask a Question
    • Do you have any successful ways of “fixing” the domes to the tray? I’ve got native perennials cold stratifying on the north side of my house. Wind generally isn’t an issue, but once in a while it could present a problem. My first thought was trying to locate some larger rubber bands, but thought I’d ask here to see if anyone has a better solution. Any suggestions would be welcome.

      Using large rubber bands or putting a weighted object on top of the domes are both valid ways to fix this problem.
