Watch our for the deer. The will chomp your head off. Also, don't go bare foot. Keep a covering of oak leaves on your feet.

The main worry is if your sap has started rising, you may get bark split which can be fatal. If you have recently had warm weather then get a severe cold snap, this will happen to some plants.

Oh Geez Louise, I shed my parka and ice skates; I was a gift and not cheap either! I'll get my neighbor to gather oak leafs (no shortage of those here they come from another yard) and put my socks back on.
Shouldn't I don a babushka too? No deer here but my buds are tender as you know Rhodyman.
