In these parts, it's mulberries. Have nuisance trees yourself?

Sumac is the tree from hell in VA. Wild cherries are a second, then red buds.

Brush is a problem down here.

I spray lots of fence lines to keep them clear.

Huisache, Yaupon, mesquite, black brush. McCartney rose hedge, oak brush, and briars are the main culprits.

Cedars here. I have some very grownup fencerows.....and I have left them that way for a reason....the wildlife and the benefits they reap.

Sage that gets big and woody.

Worse we ever had was honey locus. Russian Olive comes in 2nd. Way back in the 50's the county gave out multifloral roses(sp)Once mature, they are about 6-8 ft tall 5-6 foot across. Never even needed a fence with them. Nothing could get thru

Multi floral rose here in PA is a problem. If it would stay in the fenceline it would be great, because as Saddlesore said, you can't get thru it..

Mulberry, cherry, locust and elm

Yep, tburkepa, growing up in SW PA,we cussed the heck out of them.

Russian olive, salt cedar.

not necessarily fence rows, but privet hedge and kudzu

Generally a product of seeds getting the acid treatment in bird poop.

Pizz Elm and Sweet Gum.

For the guys with multiflora rose problems, get some Grazon Next HL. It won't come back.

Ed

Pizz elum, mesquite, and hackberry. With a smidgem of yaupon and prickly ash.

Yaupon

Mulberry, honey locust, black cherry and red cedar around here.

tumbleweeds around here......

Willow, Russian olive or Cottonwood.

Out south here its brush.

Persimmon, China berry

Here in mid TN,cedar, hackberry with afew ash,elm and and occasional red oak and sycamore.

none since i sprayed SPIKE along them.. that stuffs bad

The biggies I am always fighting are privet, elaeagnus (aka russian olive, and autumn olive), multiflora rose, wild cherry, and wild pear.

The rose and wild pear are the worst to deal with. Here's a pic of a typical wild pear thorn:



They go through gloves, boot soles, tractor tires, and steel belted truck tires.

Cedars, thorny Locusts, Mulberry, some Hackberry and Multifloral Rose bushes. Probably a few others scattered about but non that are as thick as the ones i have listed.

Wow, That is an aggressive thorn!

These wild pear trees are the offspring of Bradford Pear trees. The Bradfords are hybrids, and will produce some fertile seed. Since the parent tree is a hybrid you get throw backs from the seed. The birds love the little grape sized fruits they produce, and scatter them all over the countryside. There are vacant lots and neglected pastures where you can see acres of nothing but wild pear.

Cutting one down is a real mess. The thorns are so numerous and long that the limbs lock together like velcro. They go through leather gloves like they're cotton. And if you miss any limbs or twigs cleaning up they will wreak havoc on your boots and tires later.

Hackberry
