During the night of April 8th and 9th, the temperature was below freezing for 19 hours with a low of 20.5' F or - 6.4' C. This time only one stem of a double nose was left unprotected because the other nose has many little offsets emerging which I didn't want to risk. A small household paint pail was used as cover for the protected nose and offsets. About an inch of snow fell overnight. There was no apparent or visible damage at this point of growth.
Unprotected nose and grey paint pail over adjacent nose.
Removing the pail about noontime. The snow has melted.
Finally, both protected and exposed. Exposed on the right.
