Frost--TB

We quite often have frost in the spring when the Iris are in heavy bud--the frost will stop a bud from reaching the flower stage if it is a 'young bud' and results in a 'dry socket'--but if the buds are older and partially grown, the bud will continue to grow and usually results in a flower--a rather mis-shapen one sometimes--but the other buds on the stalk usually are o.k.--
why not think about covering it?  Plan ahead and have something all ready so if there is danger of frost you can run out and pop a top over it--a 5 gallon bucket works well--usually tall enough to cover the bloom stalk and leave some air space--if it will really get cold, add a blanket or something like that over the top--and remember to remove whatever in the morning--
