Monster Porcelain Berry
« on: May 30, 2015, 08:09 PM »
A few years ago I started corresponding with another member of this forum (coh) who lives in Rochester, NY on the matter of porcelain berry after I started the root-over-rock thread.  Eventually, I was able to dig it.  It is the biggest one I've ever seen. 

During the chaos of the last National Exhibition, I zipped over and collected it.  Still can't understand how they grow so well in New England and the Northeast but not nearly as fast in the Southeast. 

This week, I shortened some trunks and shoots.  This will eventually be a semi-cascade once I really get the thing (I hesitate to call it just a vine) full and healthy. 

Had to cut an old steel support out before the trunk got too big  ;D

Found boring insects in the dead tips of the trunks I cut at time of collection. 

Vine was planted around 2006-2008.  By 2014, it covered a large span of fence and was threatening to eat neighboring buildings.

After pruning shoots and cutting back to living tissue.

Super material, Owen.  Do you know the southern limit of their range?  I've seen photos of some great specimens, and every time I wish I had one.

Zach, Ampelopsis brevipedunculata has been spotted naturalized in Alabama according to the government types.  I'd say it should be just fine down there.  A few friends have grown it successfully in Memphis, TN.  I'd get a little one and don't let the fruit get distributed.......  Pretty sure Ryan Bell has one in Jackson, MS so you should be good to go.  It's not native to the United States and seems to be aggressive when given room to grow.

Looking forward to the repot next year and removal of the large exposed roots.  Vines are so rewarding.  Thanks go to Chris (coh) for the material.

Very much looking forward to seeing this in a future National Exhibition!

Interesting that you found borers. I've been having a major problem with them the last couple of years. They killed back the top of a styrax, a couple of mimosa (albizia), a magnolia, and a trident this spring (all in the ground, so far no problems with potted trees).  Some kind of very small black/brown beetle, they bore tiny holes into the trunks in early spring, infect the plant with a fungus, and the young grubs live off the fungus. There are many similar beetles so I'm not sure if these are shot hole borers, granulate ambrosia beetles, or something else. In any case, they can be very destructive. I hope you burned the branches that had them inside, though most likely the beetles are already in your area.

Not sure what mine are.  They likely found the  cut stumps  last Fall.  We have Camphor Shot Borer and a slew of others.  Permethrin trunk sprays a few times from February to April seem to work best.

Owen,

this is super material.

I have 2 much smaller porcelainberrys, the cultivated, variegated type. They grow significantly faster in partial shade rather than full sun. (The naturalized plants thrive in full sun.)

I also had a collected plant. The foliage kept getting some type of fungus which would not go away even with daconil. Got rid of it but will try again if I find a good trunk.

Best regards,

Could be (they found it after the chop). I never noticed  borers on the plant when it was here, but I did notice that there was a lot of dead stuff in the top every spring. Always just figured it was winter kill, though perhaps it was a combination of borers and cold.

I've already sprayed my trees once this spring with a pyrethroid, not sure if it was permethrin or bifenthrin but I've read that both can be effective. Just have to keep after it.

Good to know.  This one will be created slowly and carefully. 

Speaking of the National Exhibition, will the next one be at a different time of year?

Next one is scheduled for September 17-18, 2016 according to Bill's blog post summary of the 2014 exhibition.

Owen that tree is bad ass!

As for keeping them I think they grow any were. I have one in louisiana in full sun. Dose fine.

Thanks, Owen.  Being ignorant about the species, why shouldn't the fruit be allowed to spread?  Is the species invasive or something?  We have a great history down here of importing such awesome plants as kudzu and Chinese privet (which is useful as bonsai, fortunately, but still a pest).

not letting birds disribute the fruit is the reason. many states have it on their invasive specieslists. I believe Michigan and illinois list it.
