Reply to comment by [deleted] in Are we set for the latest first freeze ever this year? by babyyodaisamazing98

That’s strange. The lowest temp a can find for Pittsburgh was a brief hour long dip to 33. I don’t see anything at 32.

Frost can kill plants off before it goes below 32.

It also depends on where the temperature was taken in Pittsburgh. For example Lawrenceville with all the buildings and little open space tends to be hotter than Allegheny Cemetery that is mostly green space.

I’m just a few miles away from the airport and all of my flowers perished from frost the same night last week. I’m in a valley and I’m sure houses at the top of our hill may still have some left. It’s not always a blanket…temperature varies.

Microclimate! The one in my yard generally works in my favor. It tends to stay a bit warmer based on landscape features and location. So far my roses, dahlias, zinnias, and cosmos are still going. The plants in a less protected spot have started to die off. Sorry your flowers are done. Time to start planning next year....

I've had geraniums out in the open in front of my house since early May, and they're still blooming. The only ones left as of now and they really don't compliment the pumpkins out there... ;D

My zinnias and cosmos were the last two left. They were still budding, but this past weekend, I put them out of their misery. I figured I’d end their season in a vase, to hang on to the last shred of summer.
