What I would like to know is Why? do so many wysterias rot?? I have seen huge ancient wysterias covering trellises over long walks through parks, and they have huge gnarled trunks that have not rotted.
Does any-one know?
I have found that when collected, they wil rot easily and are very attractive to bugs and chewing things that get under the bark, then eat them from the inside out.
Once growing and sealed up with bark they seem to be very robust and easy to grow.
My current large collected one I have painted all cuts and open wounds, and am spraying with Lime sulphur and Confidor to see if this one survives
