Hi all, just wondering if anyone grows trumpet vines on their mature trees? I was thinking of trying this, but wonder if they would get too aggressive. I have mostly mature green ash that I'd like to try this on, but what are your thoughts? I have read that the trumpet vines can get severely invasive, but maybe that's in warmer climates. I tried growing one once on my clothesline pole and the thing has barely survived let alone flower or invade anything. I'm thinking it's too shaded there for it though.
What have you got to lose? Try it. I'll bet it is only forther south where they get realy large. Mine is many years old and although it does put up many suckers, it only gets so big. You can always kill the vine if you like the tree more and it becomes a battle.
Try it. Is the tree you want to use in a flower bed or is it (tree) a stand-alone specimen? If you mow your lawn around the tree the Trumpet Vine will be kept in check. However, if the tree is already in a flower bed, you may have problems. They can be very aggressive and may eventually rule over your other plantings.
