Any ideas how to quell the beast besides "round-up" ?
It's killing off my raspberries.
In the name of all that is holy , why would you plant it on purpose ?
(That's a joke and I hope you picked up on it )
Yes mamm , the old boys here in the willamette valley , (old 80+year old farmers) tell me to spray round up. Only where needed though. Every day if that's what it takes.Now, now, now...it will not be so bad as to need napalm. I live in zone 11 and MGs are native here and they don't cause much of a problem at all. I have them growing in my small garden on purpose (just one plant). These plants produce tons of seeds and the first thing you need to do is keep the plants from making seeds. Of course there are already seeds everywhere that will come up for awhile (maybe a year or two, not to mention donations from the birds), but not to worry. Cut back all the vegetation and make sure to cut any flowers that may make seeds. Do not compost any of the cut back vegetation, wrap it up very well in a biodegradable bag(s) and send it off in a garbage truck. Continue to cut back new growth and dispose of it in the same way. Then uproot what remains also dispose of in the same way. The nice thing about MGs is that the seedlings are fairly unique and easy to identify. From now on you will need to keep an eye out and remove the seedlings as as you find them. Some perseverance will be required but with very little trouble really the MGs will disappear, if you don't ignore any vegetation that is mature enough to make seeds. This is the primary way they propagate. I've never had a problem with root runners but it sounds like other people have. I have found that they uproot very easily with little effort. Don't panic and do something Mother Nature will never forgive you for. Actually, the leaves do not look like morning glory at all. MG vine leaves are heart shaped. I have never see MGs with leaves like that.
