Re: Styrofoam cones for winter protection

Although Colocasia esculenta and Alocasia macrorrhiza have been reported to be hardy around here, I've see nearly all of them turn into compost (except the couple that were planted adjacent to my previously heat-leaking house.  I was hoping to leave some of that material in the ground to cut down on both the fall work of bringing everything in and the spring work of replanting.  I've also read that Colocasia antiquorum *should* be hardy here (but also turns into compost).  I do have sandy soil and the compost isn't a terrible addition, but I can think of cheaper sources for the organic material.
I have both Colocasia esculenta and Alocasia macrorrhiza at my house.
This is within 200 feet of the Rappahannock River at its confluence
with the Chesapeake Bay, so the winters are very moderate--oleander survives
most winters without dieback.  The soil is sandy.  I've found that although
the Colocasia survives, mostly it seems to be buds on the sides of the
larger corm which return the following year--the larger corm usually turns
pretty much to mush.  Alocasia vanished entirely last year but I have a 
few very small bits of it beginning to come back.  I won't leave either one
out for a second winter; the Alocasia would, I feel, not survive a second
winter.  Various Calla lilies seem to overwinter very nicely (ditto Canna).

Clear skies,
