A frost on Saturday night just blackened the tips of my potatoes.

A few exposed leaves here also blackened.  All in all OK.  This was about our last frost date for the last couple of years.  The forecast although slightly unsettled is for no more frosts at least for the next 10 days.  The wind and rain may be a problem so I'll not put anything too fragile out yet.
