How to kill annual morningglory

San Jose, CA

Hello,
I'm new to this website so forgive me if I'm posting this in the wrong place. My neighbor's morning glory vine is coming under the fence and invading my garden! It is trying to climb up my fruit trees and I know if I don't watch it it could injur my tree. I've done a lot of reading and this seems to be one vine that is practically impossible to really get rid of. Have any of you had luck getting it under control? I think Round Up is the best solution used in the fall and spring. If a discussion exits about this problem I'd love to know where it is. Thanks

Round up will cause the ENTIRE vine to die and that will not make your neighbor very happy...especially if he/she is planning on harvesting the seeds to sell, or trade...

However, you have every right to cut them back to the property line.

The main way they are invasive(since the cold kills them in winter) is by seeds. If you clip the vine back to the property line and also make sure no pods drop seeds on your property, you should be fine.

You may just ask him/her nicely to plant it in another place next year and show them what it is doing to your trees...

I invited a neighbor into my yard, and subsequently she invited me into hers...Once I'd stepped over onto the "other side" I was really surprised.

I had no idea that my vines had grown so far over into her garden. She said she didn't mind, but your neighbor might really not have any idea how much they are into your trees. Even if they did, not much he/she can now do about it from his/her side, without tresspassing...

The seeds are the really big problem. They can still germinate after being buried for more than 40 years! That's scary. Ours have taken over a daylily field and they HAVE TO GO.

Ginny,
Your subject says that this is an "annual morningglory".
I am intrigued. Do you know which annual this is?
If it is annual, then it may spread in ways other than or in addition to seeding.

40 years....uhoh...it's no wonder they keep popping up everywhere in my garden.

Very scary!

Kevin, I think it's the annual variety. Don't know which for sure. No flowers yet. I didn't mention it, but the neighbor is in agreement about trying to get rid of this vine.

Thanks for your feedback.
