[quote=wheelman1976;231150]So at what point should I actually put the cones over them? Wait til the first frost and then clip the leaves and cut the PS down to fit in the box? Does that sound good?=qoute]
Yes that is what I would do.
However try this test first.
Take a soda or beer can unopened and wrap it in your most fluffy warm bath towel or warmest winter coat.
Put it in your freezer.....leave it in a few winter days.
Open it up few days later ......if the can is frozen or exploded....... well ???????
