What should I do about the weeds in my arena?

We scraped off the topsoil, compacted the clay, added bluestone and compacted it and topped it with sand and GGT.

We have weeds.

I spray them with Roundup and groom the arena with a Parma groomer but they always come back. What can I do to get rid of the weeds? I sprayed them a week ago and they didn’t even wilt.

RoundUp will only kill grass, which is probably why you still have weeds. You need to try something like Landmaster, which will kill everything, and then drag and drag and drag to loosen up the dead stuff.

RoundUp is a broad spectrum herbicide that will kill grass and most other vegetation. There are some things it won’t get, I understand. It’s not a ground sterilizer. You have to re-apply periodically during growing season.

Talk to your local Co-Op and see what they have for weeds that is “persistent.”

I use “Groundclear” for our barn road (gravel) once a spring, kills everything. I find Roundup to be ineffectual frankly.

If it hasn’t rained in your area since you sprayed round up, you might not see any wilting as the plant isn’t actively processing the poison.

There are several ground sterilizes that you can use, but they can migrate from the area they have been spread/sprayed. Some are so potent that they can damage /kill shrubs and trees.

This is incorrect.

Ride more, drag more and spray with an herbicide that also has a preventative in it. It’s an ongoing maintenance task.

Get a hoe and hand chop the weeds. That works just as well as chemicals for the few weeds that are likely to infest an arena. Just be sure that you chop them before they reach the seed stage.

As for Roundup, there are many weeds these days that are Roundup resistant.
Nothing is chopping resistant.

Generally the plant takes up the moisture fairly quickly (and if it’s dry then very quickly). You’ll see signs of a die-off within 24 hours.

Using chemicals requires constant “head work.” You’ve got to calculate your application rate, watch the weather, pay attention to equipment, etc. You can’t just fill up tank, turn on a valve, and then dope off as you drive around and around. Folks who do that generally have unsatisfactory results.

In my yearlong experience combatting weeds and grass overgrowth in my arena, Roundup has been ineffectual in killing much more than grass. We switched products after consulting a professional weed guy.

Wow, am I the only one who pulls all the arena weeds by hand? :eek:

Turn a goat out in the arena.

[I’m sorry, I couldn’t resist]

Weird. Once we start to ride and groom regularly the arena, we never have any vegetation popping up. How often do you groom?

If you read the directions for round up, there are different % per gallon dilution rate for different plants. Some will require a very lower rate and others higher. You may also have not sprayed enough of the correctly ratioed product on the plant.

I suspect this might be the issue. I’m going to spray again tomorrow at double the concentration I had been using.

I have tried the vinegar epsom salt Dawn mix with little success. It kills the leaves it contacts but the weeds grow back.

Thank you for pointing out one of the many virtues of reading the label on chemicals!!!

When used correctly most of the stuff available to the average person works quite well. When it doesn’t then consult with somebody and get a new perspective.

BUT READ THE LABEL ON ALL CHEMICALS!!!

It’s not just a good idea, it’s the law!

Another thing that can help the round up to work better is to add a small amount of surfactant to allow the chemical to taken up by the plant better, especially plants that have a waxy coating on the leaves.

I fill my sprayer with the amount of water I need, add the chemical and then add an ounce or so of dawn (depending on the number of gallons of spraynim making).

I keep an ounce measuring cup with the round up so that I can be sure of how much I’m putting in the sprayer. If the weeds are young and tender, I find I need less, but if they are well established and of the woody variety, I’ll need more.

The directions give you an idea of how much round up per gallon for the plants you are trying to kill AND the amount of spray you’ve prepared. Some plants you have to be careful, because even just a bit of drift from the round up being sprayed on a breezy day will kill the plants.

I find that the plants don’t start to ‘look dead’ until a week …or more… after the Roundup is applied.

Buy an ag (41%) type 5 gal jug of glyphosate and mix it a bit stronger. It will kill anything. I use 2 qts to 50 gallons and wipe out blackberry brambles.
