I live in southern BC, Canada, we freeze and thaw and everyone leaves them in the ground! Now if there in pots put them in the basement or shed or garage! Soon but the best gardeners say make sure they have a good drink before they go in! So good luck!

mjkjrobinson: are you sure you are talking about hoyas and not hostas? Hoyas are tropical epiphyte plants that grow in jungles.

I think hoyas probably wouldn't like anything below 50 degrees. I suggest this as a wealth of information about hoyas:

Thanks for that link popmoma. I was seriously wondering if I had been missing something all this time about hoyas lol.

They should make hardier ones though, lol!

Ya I got mixed up, my hoyas died from me murdering them by over watering and changing there pots that they had just been put in! And not hostas! So the next time I get a hoya I will be careful and not freak them out by changing pots and not over watering!

Aw so glad to hear it! I was a great plant grower then we moved to our house we are in now! Not the right light, I think we face north east so if it"s sunny get sun till noon! But my garden under the windows grows like crazy! So that"s where I put my hoyas! But I forgot the first rule of this plant don"t change pots till their happy and don"t over water! Yes I broke all these rules so they died, I cryed! Well I will start again!

Mjkj, they can be repotted... the secret is not too BIG a pot. Just a bit bigger than the rootball. And even more important, the soil needs to drain fast. You can find lots of info on here about soils...

Oh, and Sultry, I'll prompt Marco to come and answer your question. I think you'll be surprised by his answer!

Hi Sultry, I live on Tampa Bay in St. Pete. All my Hoyas are kept out on my patio/porch which is totally open facing west with screens but the top, bottom and sides are concrete and the back wall is made up of my sliders. Unless it gets down below 30, everything stays out unless it is going to be a weeklong event. My very large heirloom Carnosa took a few nights of 27 and did not blink, neither did my Kerrii, they cannot be brought in anyway due to size. The only ones to complain and turn their leaves yellow over night in protest were the Multiflora's. I know being on the Atlantic side of FL and facing NE, your conditions are different and the air a bit drier but these things really are built like tanks !

Good Luck, Marco

My hoyas stay outside too in st. Pete but we’re far warmer during cold fronts than zone 9a. Only if we go down to a freakish 30 degrees for the low would I think about bringing them in. But that doesn’t happen often and when it does it’s only for an hour or two just before the sunrise. I have a Hoya that fraustrated me years ago so I just throw it outside under a palm. It rooted into the ground and has gone wild, growing up the palm and climbing up the shed. It’s been out there for years. It has made it through unharmed even when some ice formed on the patio tables one morning . If they’re under a cover (ie porch canopy) or the dense vegetation of trees and hedges then frost is far less likely to settle on them.

Marco, that’s good to know about the Multiflora. I bought one a month ago so I’ll have to be careful with it during cold fronts. Maybe thin leafed varieties are more thin skinned when it comes to less than ideal temperatures.

This discussion has been helpful to me, too. I just moved from NC to The Villages, FL and I have covered my hoya up during cold nights. But I would love to place it on my front porch (NW exposure). So thanks, I will now do that.
