Name: Marilyn Greenwood Village, CO (Zone 5b) Garden today. Clean next week.
We have been known to have snow as early as September,
followed by Indian Summer, then up and down from there.
But generally it is probably the last couple of weeks of October when we really get our first real snow.
My rememberer is somewhat faulty
A hard freeze can be as late as January, but that is not the norm.
