Thanks for writing this. Seems fairly comprehensive and easy to understand so far. I would like to re-emphasize just how important it is to crowd out the weeds. If the Grass Roots are strong then it's more difficult for the weeds to be able to incur on the prescious land. This of course goes right into what you were saying about pH and helping your Grass to have the most suitable place to thrive.
I do have one question though on how some of you would take care of a particular problem. When I moved into this house the were many locus trees in a copes that needed to be taken down. Locus trees do NOT need open spot to grow NOR do they need sunlight NOR do they need water (at least directly).I have been battling locus trees growing inside my wood shed for years now. The shed has no light, no direct rain, but I still continue to spray round up and continue to watch the locus die only to come right back up in a month. The problem is the MAIN root system I believe, of the tree which was cut down with in the vicinity. Proximity has nothing to do with it.
I say this because in my wood shed I can just cut the root from beginning to end running through the shed but in the pasture that is impossible. If I can't get to mowing soon enough it starts to look like a locus Grove again. How do I battle at tree that doesn't care about whether it has room. Doesn't permanently die from from round up and grows new shoots from a root underground that can run forever?
I really wasn't going to get into species specific control method yet, but will address these 2.Our local agent said we have so many weesatche, we need to spray with remedy.
I hate locust. I also hate Chinese tallow trees. Both are invasive weeds as far as I'm concerned. At our previous place, we had Chinese tallow trees. I finally resorted to Remedy to kill them. Greybeard can explain how to use Remedy.
myStang89.. I'm not sure which Locust you have. Honey Locust (the one with the horrible thorns) or Black Locust. I have never tried to kill or control a black locust..they are a desirable tree here, as they make great fence posts and take years and years to rot even in wet ground.
1st, let ,me say I am NOT a fan of Roundup or any of it's generics for anything except keeping grass and weeds down around my house and yard, and then only to avoid having to weed eat much. DO understand, glyphosate can and does vaporize and translocate if used in hot weather and it can settle in places and on plants you don't want it.
1. I'm always leery of anything that claims to 'do it all' and Roundup/glyphosate pretty much makes that claim.
2. Roundup is mostly a foliar (leaf) applied herbicide, and it works pretty good on some weeds and most grasses, but for brush and trees, not so much when applied as a foliar application. Yes, it makes the leaves quickly change colors, die, then drop off too fast, and along with them, the herbicide. For brush and undesirable trees, you want the tree to continue functioning until the chemical has time to affect the root system, especially on species like Tallow, Locust, Sweet gum and most cedars. (Cedar is a big problem here, and they suck tremendous amounts of moisture from the ground that our forages and desirable trees need..and they drop lots of seeds)
Sounds like someone cut down a more mature locust and didn't treat the stump...a very common problem. Cutting down the tree (or even uprooting the thing) encourages any of the roots to send up suckers from any of the lateral roots left in the ground. There are quite a few species that do this. As I said in the opening paragraph, the part of the vascular system called the phloem is a 2 way street. It can sent nutrient rich water up the trunk to the leaves or sugar rich liquid down to the roots as necessary. It is important, that IF a tree is cut down and you don't want 6 of it's family to come to it's funeral, you need to treat the stump immediately to kill the root system--within 15 minutes of sawing it down. If you wait too long, a thick viscous material from the Zyleum will form on top of the stump and seal it off. (Stumps can be treated any time of the year, as long as the above practice is used, but IMO, it works better in the fall as most of the movement in the vascular system is downward to the roots anyway in anticipation of winter coming on)Your problem with the locust is is a bit different.
Another method, which I employ a lot, is not to cut the mature tree down at all. Kill it standing. A frill cut is made around the outside of the trunk ( I currently use a hatchet) and a small amount of diesel/herbicide mix or even straight herbicide is squirted into the frill cut immediately. Just a few squirts is all that is needed. On any tree about 3" in diameter, I just make 3 cuts, downward at an angle, about waist high, and from a 1 qt spray bottle, with the nozzle set to a stream (not mist) I lightly squirt a little in each cut. If the tree is bigger in diameter, I have to make more cuts. Some people will girdle the whole trunk, cutting the bark back all the way around. I'm not a fan of that way as I want the tree to have a few vascular paths left open to carry the herbicide both up and down. (not recommended for a tree that may die and fall on your house, barn or car)
But, since your primary original Locust tree is long gone and you are dealing with the suckers from it's roots, you will want to do the basal spray thing, and I recommend doing it in the fall on plants outside in the sun, again, just before the leaves start to change colors. With your's growing inside the shed, I suppose you can do it any time of the year, but I've never tried it inside. (again, I've not much experience at all with Black Locusts)
IF the original stump were still there, I have had some luck taking a chainsaw, cuting a couple of inches off the top of the stump, exposing new live wood and doing the cut stump treatment to that original 'mother tree's' stump. On fair sized stumps, remember, you don't need to cover the whole top surface, usually just the outer 2 inches where the cambium (vascular) layers are located. The center is usually dead sapwood that no longer carries anything up or down.
