I would also like to do potatoes, will preen effect the growth of potatoes?

bump

does the label on the preen give you any information?

Not really, I've looked on the website, and that helped a little. It said not to use it on sweet corn or potatoes, but I don't know why. They mention you can use it on certain kinds of beans, but they don't mention green beans. It also says you can put it down before seeding carrots. They also mention that the plants have to be well established---5 leaves. It looks like I'm outa luck.

I bought the Preen Garden Weed Preventer.

I read the label of Preen. I picked up a big case of it thinking I was going to put it in the vegetable garden. The instructions are so diverse for each type of plant that I thought it was ridiculous to decipher how much to put where and how to do it on all those different terms. Then I talked to different people and they said they would never put that product on their vegetables. So my case sits in the garage unused. I'll put it in my flower beds but not in my veg patch.

Preen's active ingredient is Trifluralin.

I've been tempted to use Preem, also, when I get so very tired of weeding. However, when I looked it up, I don't think I'd want to eat anything grown with this chemical. Here's a link telling about it.

Here is a link that might be useful: TRIFLURALIN

Does anyone have any thoughts on the new Preen for Veggie Gardens? It 'says' Organic on the label, but....

Active ingredient is not Trifluralin, but corn gluten meal. I'd be interested to know if anyone has used this and how it worked.

Here is a link that might be useful: Preen for Veggies

If you have a feed store near you, they might have corn gluten meal much cheaper in bulk. I got some for something like 50 or 60 cents a pound. I don't know if it works. I'll let you know in a couple months. ;)

RE: Preen 'Organic' -- I purchased some last year by mistake, instead of picking up Preen/Trifluralin, which is fantastic product. What a joke -- worthless, might as well just buy a container of weed seeds and shake them over your garden. Regular Preen works great, the organic formula did NOTHING, NOTHING, NOTHING -- didn't stop them from germinating, didn't stop them from growing after they germinated. I wasted money on nothing and then spent hours and hours picking weeds out of perennials.

I would never use it in my veggie garden. I have used it in the stupid rock around the house, but after reading the info on the link cambse provided I think I'll be back on my kneeling pad pulling out tree seedlings.

I know this is an older thread and I have no suggestions what to do after using Preen. But here are some cultural practices I have been using in my garden and have found them to work really well. I have not used any herbicides for weed control at all despite having weeds such as bermuda grass, nutsedge and wild onions.

*Smother the area with cardboard and mulch. (This may take a couple of times depending on the weed involved.)

*Apply layer of bagged leaves and coffee grounds in fall

*Walk gardens every few days (especially in winter and spring, well for me anyway because my winters are so mild) and hula-hoe any weeds that might have popped through leaf/coffee mulch.

*Mulch plants well in spring. I use hardwood mulch in the flowerbeds and straw or pine straw mulch in vegetable bed.

I had to do little to no weeding this past summer. It took 3 seasons to get to that point but it did/does work. No preen, no round-up, no bending over to pull weeds. Initially a lot of my time was used in preparing the flower/vegetable beds by covering and smothering. But I'm finding that as time goes on, less and less time is going towards bed maintenance.

Does anyone else have the problem of weeds growing IN the mulch? I lay down mulch and newspaper and it kills the existings weeds. But new seeds blow in or runners creep through the neighbor's fence, and set down roots in the mulch. They use the mulch as a growing medium. I pluck and I pull, but in the summer with the rain, heat, and sunshine, it's a losing battle.

The hula hoe helps me control any weeds that develop from blowning in as seeds. As for bermuda grass creeping in, I start every spring and fall by re-edging the mote type edge that I have around each bed. The rest of the growing season I spray food grade white vinegar or use the weed wacker.

If and when Bermuda grass manages to creep into a bed, it usually pulls up very easily from my amended soil as long as the soil is relatively moist.

Yes. What i do is dig an area out about 6in wide 6in deep and fill it with clean garden soil and plant my seeds in that if i have used preen on my entire garden. Or if your doing a whole line like for pole beans or whatever, you could do a 6in wide 6in deep trench for the length. So whatever seed it is your planting, just make sure it has enough clean soil to keep it protected.
