Minneapolis is not ready for zone 5 yet
2026-Apr-18, Saturday 05:47 pmI'm a big advocate of recognizing climate change.
For instance, back in 1960, this USDA map shows Minneapolis in zone 4a. Sometime later, we changed to 4b, and today we're in zone 5a. We're still fully surrounded by zone 4b, though, so it's only because of the "heat island effect" that we're considered a warmer zone. You can see that island of heat on this map. That's fine, I suppose.
Unwelcome, however, is receiving plant shipments on dates that are still too early for actual cold weather habits in this part of Minnesota. I planted things a few weeks ago, when they shipped much too early, then we had a hard freeze down to -7C/20F. I received more plants on Thursday, only a little too early. I kept them indoors, because I saw the forecast for below-freezing temperatures this morning. That's also fine, I suppose. After work today, I got some asparagus and roses into the ground finally. I had to dress warm, because the wind chill was 3C/37F.
I have a few more delivered plants to put into the ground, but I'm waiting until Monday morning's sub-freezing weather passes. One of these plants is another rose, but it's already blooming! It just seems terribly wrong to try putting it into the ground right before a freeze.
That photo isn't great, but the single open flower at the top is still visible. These last remaining plants will just have to wait for Monday afternoon. I wish all of these plants weren't delivered until late April, like what would happen years ago, when we were still in zone 4.
