I would cover them if that is feasible. We had temps in the 20s for three days aft we some of my roses were budded and I have a lot of defective malformed blooms opening.

I'm in zone 7 and my roses are no further along than yours, Jo. Plus it's been snowing off and on for the last 24 hours, and it was 28F last night. Anyway, no, I don't cover anything, and as Magpie said, don't bother. Diane

@Michievous Magpie Yes, sorry I should have clarified that they are leaf buds.

In my experience, if the leaf buds have not sprouted leaves, no need to cover. Furthermore, roses generally do not sustain significant damage after spring leafing until temps are below 28F. At 28F in my experience, they are fine.

Ohhh sorry lol that was dumb answer. I assumed the post meant flower buds and missed the zone factor. My leaf buds gets zapped almost every year since our temps fluctuate so much during late winter. I do not worry about leafbuds or new foliage ever, the plant will make new ones when the temps are right again.

If you do happen to get down to the mid to low te ties after having flower buds I would recommend protecting if posible to just removing them and letting the plant make new ones (if not dealing with a once bloomer). We were in the low 20s for a 3 days and many of my buds looked ok only to open as ugly malformed blooms.

@dianela7analabama No worries! I should have been way more clear,lol Thanks for the advice :)

@mark mark Thanks for your help!
