Cold stressed Crossvine Questions

My Bignonia capreolata was putting on tint buds when the the dreaded coldfront; 2 ice storms and two snow storms hit in 9 days. The single digits hit without any hardening off process....This is central Texas. Our winters are often periods of extended warmth with some interspersed minor freezes. This winter was WARM until then. This is what it looked like in March a couple of years ago. It is an established vine that I have never ever trimmed back. I did notice that it was needing a trim back because there was a growing amount of long bare vines in the mess. The plant is very knocked back due to the cold right now. I Trimmed back the small twigs till I saw green in the twigs but I am noticing that the once trimmed green twigs have become dry and brown so I have trimmed more off. I have trimmed it back more than three times. I am noticing some new growth on the thicker stems and some of the thinner stems closer to the trunk of the tree. There are exceptions to this observation. I am trying to wait and see but my clippers keep jumping into my hands. There is also that part of me who wants to cut it back rudely to promote all new growth but I am a bit of a wimp. This vine has been very well behave by never suckering and I LIKE THAT. I am not that experienced with vines. and their care.


Here it is at the same time of year this year bare as can be.



Area of growth closer to the trunk of the vine.



The area further down the vine. It is hard to see what is old dead bud growth and new live growth . I am torn between waiting thinking that the sap that was knocked back is trying to get to the extremes while there is a slow centralizing of the vines strength. I really do not know what I am doing and deciding action is a waffling process.



an area far down the vine mass with progressively less evidence of new growth but with green under the surface.



I am interested what others do with this vine after a hard winter. Especially from people who live in cold areas since it is capable of growing much further north. I am in Central Texas west of Austin. That is why I put this out on multiple forums. Should I wait for all the growth to leaf out before trimming back? Should I only trim to the limits of regrowth or knock it back hard? Will a hard trimming encourage unwanted suckering? This vine has been really good at taking care of itself. So many consequences make me into a waffling gardener.

    i know this is new to you ... but up here in my MI ... we can have damaging frost thru mid may ... its just part of life up here ... and all you can do.. is wait until the plant shows you what is live.. and what is dead.. and then you go after it with a fury of mother nature like you dont know.. lol .. thats how you release the stress of it all ... damaged areas may still bud out later ..


    in all my years of dealing with this ... you just have to wait and see ...


    or cut it the ground.. and then wait and see ... at least it outta sight then.. and you arent irritated every time you walk by it ...


    key words.. just wait .. plus.. and see ...


    go all zen on it.. and just take a deep breath.. and wait ...


    ken


    ps: and see ...


    pps: of course.. my plants for my zone 5 are mostly z5 plants.. and even lower zone ... part of your problem is you had a z5 event.. and most likely.. a lot of your plants are higher than z5 ... and btw ... snow is usually not an harmful event ... ive seen it snow up here when its 40 ... because up in the cloud it isnt 40 ...

    Long lasting Snow and Ice is harmful if you grow agaves and Yuccas from the Big Bend and Arizona. Ah another problem.They have the cold hardiness but not the ability to withstand a nine day ice and snow event. I just cut down a 15' Y. faxoniana who had lived 20 years. What a rotted stinking mess. The roots seem to be good and I see a new knob close to the trunk. I hope it gets the energy from the root system.

    Actually the specific problem with extended cold is freezing of the soil. So plants that might come through a sharp night or two with warm days between can't handle cold lasting long enough for significant penetration of the ground. Because these don't in fact have the hardiness for it.

    Cross vine is hardy to zone 5, which is why yours is leafing out, even if sparsely. The problem with the February freeze was that up until that point we were having a south Florida winter. As you noted, nothing ever hardened off this winter. In fact, one of my elms was blooming a few days before the freeze. Your vine is obviously not dead, but the smaller stems may have been killed back. I don't think you have to cut it back to the ground, but you may have to cut it back to where it looks best.

    My elms are burgeoning right now. No damage there. I didn't even get any ice damaged broken limbs on them. I wish I could say that about my oaks.
