Frost can signal that the end of the gardening season is near – but not necessarily over.
I have a good friend who recently said “I am sick of the garden – I just want it to be over.” If this is you, then when frost threatens, by all means do a final harvest of the tenders and call it done. If it’s not you, there are many measures you can take to protect your crops from a killing frost incident, as more times than not, such an incident is followed here by an Indian Summer and at least another month of flower and vegetable enjoyment and harvest.
