Well, let’s talk about them hydrangeas, the pretty flowers everyone loves. Folks always askin’, “Hey, when do I gotta cover them up?” It ain’t rocket science, y’know. Just gotta keep an eye on the weather and those little flower heads.
Now, what temperature should I cover my hydrangeas? That’s the big question, ain’t it? I tell ya, it ain’t one magic number. See, different hydrangeas are like different folks – some tough, some a bit more delicate. But generally, when that ol’ thermometer starts dipping down close to freezing, around 32 degrees Fahrenheit, that’s when you gotta start thinkin’ about coverin’ ’em up.

- 32 Degrees Fahrenheit (0 Degrees Celsius): This is the danger zone, folks. A light frost can nip those tender buds and leaves. Time to get them covers ready.
- Below 28 Degrees Fahrenheit (-2 Degrees Celsius): Now you’re in serious trouble. A hard freeze can do real damage, even kill the whole plant if you ain’t careful. Definitely gotta cover them up good and tight.
- Below 0 Degrees Fahrenheit (-18 Degrees Celsius): If it gets this cold, even covered hydrangeas might struggle, especially if it stays that way for a long time.
Some folks say hydrangeas can handle minus-10 degrees, but I say, don’t push your luck. I ain’t never seen a flower that likes bein’ frozen solid. Better safe than sorry, I always say. If you see frost coming you just go cover them up. It’s like puttin’ a blanket on a baby. You wanna keep ‘em warm and snug.
Now, how do you cover them? Again, ain’t nothin’ fancy. You can use old blankets, sheets, burlap sacks, even cardboard boxes – whatever you got handy. Just make sure it covers the whole plant, all the way down to the ground. And don’t forget to weigh it down with some rocks or bricks, so the wind don’t blow it away. You don’t want that cover flyin’ off in the middle of the night, leavin’ your hydrangeas naked in the cold.
Some folks like to use those fancy plant covers you can buy at the store. They work good too, I guess. But me, I like to stick with what I know. An old blanket does the job just fine. And it’s cheaper too!
And when do you uncover them? Well, that’s just as important as coverin’ ’em up. You don’t want to leave them covered up all day, especially if the sun comes out. They need sunshine and fresh air just like the rest of us. So, once the temperature warms up above freezing, take those covers off. Let them hydrangeas breathe a little. You don’t want them things to suffocate now, do ya?
You gotta pay attention to the weather, see? If it’s gonna be cold for a few nights in a row, you might have to cover and uncover them hydrangeas a few times. It’s a bit of a hassle, I know. But it’s worth it if you want to see those beautiful flowers bloom in the spring. And remember, spring is when all those beautiful flowers come out. I just love seein’ them, don’t you?
Now, some hydrangeas are tougher than others. There are some that can handle colder temperatures, even down to minus-30 degrees! But them are special kinds. Most of the ones you see around here, they ain’t that tough. So, it’s always best to err on the side of caution. Better to cover them up when you don’t need to, than to leave them uncovered and lose them. It sure is sad when I see folks not coverin’ them and they just go to waste in the spring because they did not cover them during the frost!
Signs of Temperature Stress, you ask? Well, if the leaves start lookin’ all droopy and wilted, or if they turn brown or black, that’s a bad sign. That means the cold got to ’em. And if the buds are all mushy and soft, well, that’s even worse. That means you ain’t gonna get any flowers this year. So, keep a close eye on them hydrangeas. They’ll tell you if they’re in trouble. You just gotta listen.

So, to sum it all up: cover them hydrangeas when the temperature gets close to freezing, uncover them when it warms up, and keep a close eye on the weather. And if you ain’t sure, just cover them up anyway. Like I said, better safe than sorry. And that’s all there is to it. Now, go on and take care of them flowers. They’ll bring you a lot of joy if you do. Taking care of your hydrangeas is a good thing, and it’ll mean you did a good job!
