Nights are still in the fifties here. It's probably three or four or even five weeks before hard frost. With highs in the high eighties, I'm hoping to get some good root growth on my roses before winter. I know mulching is in order. Not sure if I'm up for it.
I like funguslessness better than fungi-free zone FFZ. Several weeks ago we had DW's great nephews here for a week that we called camp B&B - four boys between seven and twelve. One wore a tee shirt with a smiling mushroom that said "I'm a fun guy." If this were a fun-guy free zone, it would be a little boring, I suppose.
