I use extended preen twice a year, good for 6 mos. My big problem is crabgrass that grows in the bushes. HD suggested a spray to attach to hose, but directions say not to use in 90 heat so i 'll have to wait. Preen will not kill crabgrass, but HD gave me a granular crabgrass preventer to spread in the early spring. We'll see how that goes.

Weeds can be pulled up completely if the soil or mulch is very wet. Go out after a large rain or do a lot of watering and then pull s l o w l y .

Spray on the weeds because, like round up, it kills everything. Do it in the morning on a hot day, with no rain, and you will see things die pretty quickly. Preen keeps seeds from emerging and is very effective. I never use salt. It remains in the soil and cannot be removed. The black weed barrier does not allow water to penetrate properly, that includes, fertilizer, which can run off in different directions and not go where you want it to. Yes vinegar is a chemical but not like round up which can be very nasty to you and the environment.

I use the 30% vinegar straight up with a little dish soap to make stick to the weed leaves. Works great, but the smell is nasty and lasts until a good soaking rain.

Roundup has a version that lasts for three months, and also one called 365, which is supposed to last a year. It doesn't, of course, because of the amount of rain we get here, but it does work for a long time. I have used it on our CYV stones, including around trees and bushes, with great success. When we leave TV for six months, I cover the whole area. I don't have the back for hand-weeding and don't want weeds taking over while we're gone.


I don't understand why OP doesn't want to use a weed mat.

It has been banned in some countries, especially for farm use. But if you are careful and don't use it on a windy day, it won't cause a problem.

A Covid silver lining. I never had a mask at the house to wear when spraying roundup. Now we always have plenty of masks available!

You also can't spray it in any garden that grows vegetables or herbs if you intend to consume them.

You can spray it if you have potted plants raised above the ground, but if the roots of those plants are going through the hole of the pot into the soil of your garden, you would definitely not want to spray Roundup anywhere near those pots.

I just pull the weeds out every week. If I come home from work and see a few stragglers I grab them on my way into the house. So my "weekly" weeding session only takes around 40 minutes.

That’s pretty much what I do, except I add Preen to the system. My weekly session is about 5-10 minutes.

It's inexpensive, only labor-intensive for a day (you have to pull back all the mulch, lay it down, then toss the mulch back over the barrier and add a fresh layer), and will prevent a good percentage (not all) of weed growth. After that, you just pull the individual weeds out as they show up.

You'll still have to kill off or physically remove the current batch of weeds before laying down the mat but you'd have to do that whether you have a mat or not anyway, so that part isn't any extra work.

Landscaping is outside my wheelhouse....for the most part. One of my kidneys contains bushes - a few of the bottom branches are growing down/into the mulch and dropping a root system. I don't want to choke that growth with a material barrier.

The other kidney is just trees and I'm thinking about doing it there. Thanks for your insights.

Found another lawn service who did the proper job plus sprayed a Roundup like product (non cancerous) to kill the remaining little weed sprouts that pop up.

Point on. I have that going on too and have advised the lawn guy. Thanks...

Is there a chemical (been trying to avoid that but at this point I don't care anymore) that I can use that won't harm the tree/bushes but will kill weed growth?

Or do I just keep pulling hoping for the day when there will be no more weeds?

Any other suggestions?

Thank you.

Even if you put barrier down the weeds will eventually still pop up. Best to us weed killer when the weed first sprout before the Blum and are easier to kill when young.

You need respirator

Yes, I’ll jump in and say mask does nothing! Need respirator.

1/2 cup Dish soap

Works great on our paver driveway and pool area and it non carcinogen.
