It is Friday and Fridays are for fun. Everything in nature has a purpose, even cold weather. The cold does kill off some invasive species of plant, animal, and insect.
As a gardener, I know that I am in zone 4 and that some plants that are perennials in warmer climates will not survive a Minnesota winter. I have had some zone 5 plants survive several winters before dying off.
The emerald ash borer has evolved to survive our winters. Once the temperature gets lower than -13 some will die off but there will be plenty of them to kill off our ash trees. Most of the Ash trees along west 7th street were removed last year because of the pest.
Insects larva survive by developing sugars and proteins that act like antifreeze and keep them alive during the arctic cold.
There are plenty of critters that live in the south that can not survive our winters. There are various diseases that harm plants that get killed off during the deep freeze too.
There is some benefit to the cold weather. I just wish that we didn’t have to get it all at once . . day after day. . after day. . .
