Can this also be used as a weed prevention measure, or is it best when the weed has emerged, and is visible

Most of the time I shoot all exposed then about every week I touch up on new growth

This is a product I use to prevent weeds from sprouting from seed. So I would recommend you use live plants or slit the paper where you want to plant the seeds. Remember this will biodegrade each year. I love it because I do not have to use herbicides and I can still plant. However, the down side is until I get weeds under control in an area, I have to reapply it each year. I have an acre of untamed land and am slowly getting it under control.

I have had great success with a product called 'Over the Top'. It kills grass, including ornamental grass. Snapshot does an excellent job of preventing weeds from germinating, but it also prevents self-seeding annuals from germinating. If there is a silver bullet for all weeds in a garden, I haven't heard of it.

I do believe that Tenacity killed this particular weed. I plan to apply it again preemergently in the spring (in central Ohio). It worked miraculously on quack grass, clover and a variety of other weeds that no other product could touch.

Not clear why other commenter didn't get expected results. I recommend - with any weed killer - painting it on rather than spraying, when you are working around other plants.

You could use it for either one. If for soil you'd primarily use it as a foliar spray.

You can use it for poa annua but, it will be very slow going. This tool is only able to pull one weed at a time. Best way is to control poa annua with pre-emergent.

You can use it to grow anything including weed. Keeps your growing operation more private and less transparent to be sure.

Yes as this is not a pre-emergent weed killer it won't kill anything planted that long after spraying. I assume you want to kill weeds in a flower bed or section of your yard, this will not prevent whatever you are trying to plant from growing, now if you spray it after it emerges it is gonna die and die hard.

I used it as a weed killer, it is very strong and will burn, use with caution.

The Preen pre-emergence can be used on weeds 2-3 weeks old; you may be a little late for existing weeds; however I put this down every 3 months to control weeds throughout the summer season. This will really help in July / August when crabgrass and misc. weeds go nuts in the heat.

it might be visible, but dont count on using it during the day time. for day time visibility you are better off wearing neon clothing and using hand signals.

I use it with limited visibility degradation. I do suggest you check your state laws though.

I was reading the instructions and it is best to use in the spring where dandelions are most visible... As far as the winter I don't know the effect it will have on weeds.

Yes, I usually spray it on the edge from rock or mulch to sidewalk. I wouldn't spray in the center of my lawn if a weed patch is growing there

It's best if you can be patient enough to let it wither away like you do when you use weed killer. Depending how much you have, you certainly can pull it out though and then reseed.

No, it's very powerful. I think you need to use "weed be gone" if you don't want to kill any grass.
