Clematis and frost advice

Patty W. zone 5a IllinoisApril 7, 2010

Like it or not my clematis came up. Most are about six inches to a foot tall and leafed out. I know the perennials will be fine. Unfortunatly any frost will toast the new rose shoots and some of the leafed out hosta. How do new clematis shoots handle frost. I've never had this happen before. Thanks Pat

For some odd reason, I've never thought about this situation in connection with clematis, but I'd hazard a guess they will do all right. I've grown clematis on the back fence for years, mostly ignoring them until they bloomed. Since almost every year we have one or more late freezes, they must be fairly tough--I've never done anything to protect them under such circumstances.

Perhaps others have had different result.

We had a devastating late freeze a few years ago that damaged trees, my roses and nearly everything except the clematis. I never really understood why that was so, but I was happy for the fact that I at least had clematis blooms that year. I've never had clematis damaged by the late freezes we get here on a fairly regular basis.

Many Clematis are hardy down to zone 3, most to 5 so they should be fine.

Thank you so much I did cover the roses I'll never forget the damage done by that same spring freeze. I'll admit I coverd a few clems also. Thanks again Pat

That big Easter freeze a few years back killed my Sweet Autumn Clematis. SAC had 4-5 feet of nice new growth when the freeze hit. Within 2 days of the freeze all that growth had turned limp and white. The plant never recoevered or re-grew. Last year I purchased a replacement late in the season (so I was sure I got one with fragrance)

This was the only Clematis I've ever had that was damaged by cold temperatures (in fact, my triternata Rubromarginata has been growing since late Feb here and was unfazed by temps in the high 20's last night)

We got 6" of snow a few days ago and all the clematis were already growing. So far all of them look great.
