  1. I keep my shamrocks outdoors all season, putting them in a greenhouse with the other tropical plants during the winter, this year we had to get a new greenhouse but when the first one arrived it was the wrong size so we are waiting for the correct one to get here…meanwhile it is getting very cold and will fall below freezing tonite…I have no room to bring in this giant pot of shamrocks…will they survive? What can I do?
