As a gardener, one can deny, argue, ignore or whatever the indicators of changing climate but one thing for absolutely certain your veggies will NOT.
This year for example:
1) I harvested huge crop of potatoes in January as well as fresh ripe tomatoes...never before that time of year
2) have huge carrots in the ground that all need to be pulled...never before that time of year
3) big crops of beets, brussels sprouts, cabbage, and broccoli all maturing...never before that time of year
4) spring bedding tomatoes and tomatillo plants set out end of February...never before that time of year
5) currently planting out spring garden beans, squash, corn, peas, etc.,etc. ...never before this time of year.
It has snowed here on April 15 during my gardening lifetime and for years I've been perhaps overly cautious about planting out too soon...but I have no hesitation this year. Maybe I'll get burned but if I don't get the warm weather crops started, they will likely burn up in July and August.
