If I put Preen on my Poppy bed now, do you think it would ruin the poppy seeds? They don't germinate until September or so. The Preen would be pretty much gone by the time they sprouted. I am tired of pulling weeds!
I believe there are 2 preen seasons .Spring and Fall.( I might be wrong) the lable says the product is active for many weeks. I just bite the weed bullet and dont preen where I sow poppies. The Preen is effective for 12 feet so I give it a wide path.
I preened this year and while I have very little if any chickweed, I have weeds that must grow from roots. You would think that if I pull those up and preen next year I would have fewer of those also. But this years poppies are not so good looking. Transplanting doesn't do any where as well as just broad casting. Hoping for enough representative seeds to correct that next year.
I don't know how I missed returning to this thread. I am inundated with weeds--especially chickweed. That weed has tender, short stems that break off at ground level and re-grow. It was still blooming at Thanksgiving which means it was still making seed. grrrrrr.
I certainly hope the preen doesn't ruin my poppies. I have had them for many years. When I put the preen down, I had forgotten about the poppies. We have snow on the ground, or I would go check my poppy garden. I do recall seeing small Larkspur plants in that garden.
Thanks to all that responded. I did not ignore this thread on purpose.
I am not as talanted with Preen but was lead to believe the toxic effects last for quite a number of weeks.
I dont preen in the gardens where annual poppies are sown.Mu Orientals do OK.I never check them.Lamiums are so thick weeds dont get started.
I have BitterCress.It forms matts in fall and winters over.Impossible to get rif of.It has profuse seeds in spring that jump off the stems if the plant is touched.
Oh, I have that one also. :( But, thanks for the link--also like the idea it can be used at low temps. Maybe we can get a head start on those rogues! We have snow right now-but when it melts, I am going to take a look at my nice thatch of chickweed and see if it's still green.
