Ambitious Forsythia removal

Posted by poaky1 6 Pa (My Page) on

As in the title, I have a Forsythia that is hell-bent on taking over part of my yard and the neighbors driveway. I want to get rid of it because being nice and pruning back a good bit of it is not going to cut it. It just pushes out more growth and is a never ending battle. Roundup only affects some of the new growth. I haven't tried the brush or stronger ROUNDUP formula. It is intertwined with a spruce (norway spruce) that I want to keep. I can try to spray something on the Forsythia and avoid the spruce, but burning would be out of the question because of the spruce.

My Forsythias are fairly shallow rooted so simply pulling the plant out, roots and all, should not be that much of a problem. No need then to spray a plant poison that is harmful to our envrironment.

Definitely try digging it up first; as kimmsr says, forsythia are fairly easy to uproot (thank God). If you can't, cut it down to the ground and keep cutting it down when it sends up shoots - you should be able to exhaust it that way.

I didn't tell you how big it is did I? It is about 30' around in a circle. It's been there for about 16 years. It will be hard to even access the original trunk. The shrub was planted before there was a neighbor on the other side of it.

Just start cutting -you'll eventually get to the middle, and you may be surprised at how small (comparatively) the center is. My parents had a forsythia hedge that was about 15 feet deep, but the base plants were about 2 feet by 2 feet. Hopefully you will find something similar. I do recommend that you try digging it up before going to Round Up - have your pruning shears handy to cut the roots.

I tried brush and poison ivy killer. I feel a bit guilty I must say, but I don't think it is going to even make the Forsythia wilt alittle. Regular round-up did nothing at all. I may have to pay for some help on this one. I can't see me doing it alone. Thanks for the replies.

The brush and poison ivy killer was a waste of money. The Forsythia is not the least bit stressed by the application. I need to figure something else out.

You've got to cut it down first - a forsythia that big has too many leaves and too much new growth to be affected by a spray of anything, unless you cover every single leaf. The timing is bad, too, as common wisdom says that herbicides as a rule work better when the plant is actively growing - your forsythia is shutting down for the winter.

Cut it down to stubs, then put a little bit of full-strength Round Up (the concentrate) on the cut surface of the stubs - just enough to cover the top, making sure that it gets where the bark meets the inner wood.

Think of it as Samson - if you cut off its hair(branches), you will weaken it to the point that you can do what you want.

I will try that this fall or next spring.
