Beans, cucumbers, and squash should be safe to plant when the lilacs are in full bloom.

The timing of lilac blooming (and leafing) was studied in-depth by a professor at MSU. We wrote about him last year.

Montana’s Greatest Climatologist

My one class in climate studies was about 40 years ago at Montana State University.  The professor was Joe Caprio . . . yeah, “The Father of Scientific Phenology.”  It’s interesting how many state climatologists make their starts as meteorologists.  Anyway, I was back in school, getting enough credits in ag engineering to qualify as a professional with SCS, and when I took his class on climate, and when he learned of my experience in snow surveys, it became Mike and Joe – a very honored Mike that was told “Call me Joe.” Dr. Caprio’s specialization and research was climate…
