Preen Garden Weed Preventer, 13lbs

[This review was collected as part of a promotion.] I have used Preen for my flower beds for the last several years. I am elderly & cannot bend over to weed so this is a godsend. Last year I started using it in my vegetable garden. Since I only plant established plants it worked really well. Between using the preen & a muclh, my garden was a breeze to care for.

Purchased your product for years and have never seen it work so poorly. I even reapplied and still am spending hours weeding my garden. It's either a bad batch or they're reformulated and it's now a bad product.

I'm a PNW flower gardener and Preen works! It is truly a back and knee saver! Every January I check my flower beds for emerging weeds and moss & pull them out or hoe. Then immediately sprinkle Preen all over the clean soil avoiding emerging spring flower bulbs such as tulips, daffodils, iris, peonies, etc. Preen keeps my flower, herb and veggie beds weed free, especially before Easter when the spring flower "show" blooms! Many people stop by to walk thru my garden and always ask how I keep weeds out of the flower beds and I always recommend them to buy and regularly use Preen b/c it works! It's a winner!

Preen works. It's not perfect as it's important to remember to put it down before there are chances of weeds starting to germinate, and if it were perfect, I wouldn't have to remember to do this in time! LOL. I have a steep hill which has been a nightmare to weed; actually somewhat dangerous it's so steep. I started using Preen every winter (I live in CA where weeds mainly grow in the winter) regularly to control the germination of weeds around the existing plantings. It gradually worked better and better. I've been using it for about 10 years now. I think over that time the weed seed bank has been exhausted and now weeding each year on this area, which used to take about 20 hours per year, now takes about 20' or less. Many people may not realize that pre-emergents actually kill the seeds. They don't stop the seeds from germinating; they kill them after they start germinating. This is ideal because over time, it will gradually kill all the weed seeds in the soil surface. A key is to not till or otherwise disturb the soil because you'll just keep bringing new seeds up to the surface and you'll never get rid of all the weeds. Preen is expensive, but it has saved my lower back and knees. Well worth it. Oh and it has never appeared to hurt any of the existing desirable plantings. I wrote this review because I saw a bunch of one star reviews and actually got a bit mad. This is a good product and it can help deal with overwhelming weeding situations. I didn't want other people to think it didn't work. It's just that, like with any herbicide, there are instructions that need to be followed carefully and the target weeds and the timing of application are critical to success.

I have used this product for the 1st time this year after I redid my landscaping and this product seems to be doing exactly what its suppose to do, so far!

I used this 2 weeks ago and followed the instructions. Weeds have already come back.,

I tilled my veggie garden mid March then applied Preen heavily, raked and watered in. Tilled again mid April, applied heavily again and watered in. Planted May 1. Now weeds starting everywhere. Should one should apply it so thickly that it acts as a mulch? See pic and scroll in

I have used Preen Weed Preventer and had success for the past 10 to 15 years. This year, it did not work at all. I applied it the same as I have in other years just before a rainfall, with the scoop, etc. I have never weeded more than this year! The same weeds it has prevented in the past are taking over my landscaping. I have talked to a few people who use it, including family members, and they seemed to have the same situation as I am experiencing. What happened this year? I use 4 of the 16# size. It was unfortunately a big waste of money and time this year. Disappointed.

bought the black mulch with the weed prevention and didn't work at all. Within a few days I had more weeks than normal. Huge disappointment

I would not have used Preen over 20 years if I wasn't happy with it. Theressa

Tried this stuff a few times and each time same results. Weeds thrive on this stuff, never seen one dead weed. Just a lot more weeds. This years tried it in a much smaller area and same results. Weeds was less until I put preen on it than holy smokes they weeds are horrible. Pretty sure they put some kind of fertilizer in this stuff because weeds love it!

I have been using Preen and Green for years and it works wonderful! It works best in the flower garden if you put it on in the early spring around plants that are at least 3" tall. Lightly scratch it in the ground and water or put it on before a rain shower. It won't work as well if you put it on and then put mulch over the top. If your going to add mulch then put it on the top of the mulch layer and scratch it in and water. If you need to, say if you have a lot of rain, then reapply after about 2 months, again take it in lightly and water. I've also put it in my vegtable but not until the plants are up at least 3 inches. I think people who have had poor results probably haven't read the instructions, this is crucial!

We have used PREEN for several years, however, I had some left over and I an experiencing a flush of weeds. Could it be old PREEN? We have had lots of rain so perhaps that is the real cause.

We have rock landscaping and large trees in our yard and the neighbors, these trees have thousands of twirled seed pods that come down, preen does not work on these, on weeds seeds it works great, on tree seed pods I don't think it does any good, so for what I need it for it does not work any suggestions? Even spraying with roundup and weed be gone I have to spray 2 to 3 times to kill these when they sprout!

Before I use this poduct around our 6 blueberry bushes, I want to be reassured it will be safe. They always give us plenty of fruit for the summer, I dread losing those fruit producing bushes. Thank You !

Our Britney Spaniel rolled in mulch that had just been treated before watering. Went into convulsions, gave dog a bath and it was fine.

Second year in a row I've raked and roughed up our flower bed, applied preen, then a layer of mulch, only to have more dandelions growing there than in my untreated front yard.

I've been using Preen for years. Living in MA I put the Preen down in March or when the snow has melted off my 20+ flower beds. It doesn't matter if it snows after I put the Preen down, I will not get any weeds until late October, at that point who cares! Just love this product.

I heard about Preen from my son-in-law and tested it last summer in one area. It was so incredibly successful that, this May I spread it throughout all my landscaping. I have not had one weed in three months! Seriously! Now, I admit I likely overdo it.. probably buying more/spending more than the directions dictate. I carefully sprinkle every single inch. I have had no problems getting it fairly close to my Hostas and other landscaping plants. Yes....you must have the spots completely free of weeds first...this is a weed preventer, not weed killer. And, I'm careful to put it down when I know we will get rain within 24 hours. Let me tell you...it works! I don't have time to weed during the summer and this was SOOO worth it!

Have used this product 2 years in a row now and spend a lot less time weeding. The 2nd year there were less weeds and grasses sneaking up in the spring to clean up before the application of spring preening! I plan my application just prior to a rain shower.
