Protect your terracotta pots from frost damage by encasing them in a micro-fleece jacket. Plants sit on a 4cm layer of insulation. With a Velcro opening, the Planter Jackets open up and are easy to put on and a drawstring ensures a snug fit at the top.
A good product. Not sure about the polystyrene in the base (probably good for exposed pots off the ground). I will use it on the top instead and just push straw underneath as the polystyrene will block my drainage holes (not in middle of pot). I will also add some padded envelopes down the side as the padding is thin bubble wrap and we can get down to less than minus 10 degrees.
