the san pedro survived last winter, boy was i surprised. It is more fun , in my humble opinion , to set them up to survive without plastic. and i am constantly surprised at just how well they seem to do. I know the semps will do fine, thats why i dont really care about them, same with the pricklys. Now if the little echVerias and graptos can survive that would be something. Some of the plants survive but dont seeem to regrow the following spring.
@dutchlady1 Thanks much , if i did not hack them up every spring i bet they would be huge by now...
