Rhubarb -- Frost Damage

Rhubarb hit by a frost or freeze can still be eaten PROVIDED the plant/stalks are still firm and upright.

Leaf injury may be noticeable with some brown or black discoloration on the edges. Severe cold injury may cause the oxalic acid crystals in the leaves to migrate to the stalks when poisoning problems can occur.

If in doubt concerning the safety of eating the stalks, DON'T. Cut those stalks off and compost. Allow new stalks to develop before eating.
