Question using Caseron --

mmmgonzo(z7 OR)April 2, 2012

I know you cannot plant seeds in the area you have used Caseron for a year (at least this is what I have heard).

Can you plant seedlings (annuals/perrineals) or rose bands?

Spreading Caseron is on my "to do" list and if I need to leave some areas clear (mostly to plant new roses) I will.

If I can however use it everywhere, that is even better :)

I don't think I would plant anything in that area before the instructions indicate it's safe. From the Arnold Arboretum's site about their use of it, "It is a root killer, especially effective for controlling such broad leaved perennial weeds as quack grass, Artemisia,
Canada thistle, curly dock, fescue, leafy spurge, orchard grass, timothy, wild artichoke, wild aster, yellow rocket and wild carrot. It also controls many (if not most) of the common annual weeds with which we have to deal in the
Arnold Arboretum."

Are the plants you desire to plant there now listed? You MAY be safe IF the plants you wish to plant aren't susceptible to the herbicide and IF the concentration of the herbicide isn't still high enough to attack young plants, and IF the plant is sufficiently mature to withstand the herbicidal effects of the remaining concentration. You could try it with one or two to see as long as you wouldn't mind sacrificing them in case it's too early or they're too young. Good luck! Kim

When I looked at the chemical hazards document for caseron, it's not pleasant. The effects are long lasting. I spent over $40 of that stuff to spray a patch of crabgrass. It was worthless, the crabgrass spread even more. The next year I pulled the crabgrass by hands when the weather is hot and dry. That got rid of the crabgrass for good.

If I had known the above, I would had pulled it by hand when the patch was smaller. At the libary I saw a landscape guy sprayed a tiny weed with a giant canister of chemicals. It would had been faster if he bent down and pull up the weed by hand.

My neighbor had a huge patch of crabgrass the size of a bus. Tee-time lawn company sprayed her lawn with lime and other stuff. Here the stable uses lime to deodorize their horse stalls. I used horse manure (has lime) as mulch, resulting in ZERO WEEDS and ZERO fungal diseases in my rose bed. In contrast, there's tons of weeds where I mulched with free bark mulch.

I use our wood ash from our woodstove to change the pH and make the 'wiregrass' areas less friendly to wiregrass. Then I go in and take out the stragglers.

nasty stuff- used to be the go-to weed killer of choice for municiple use until the many complaints started rolling in regarding spray-happy contractors. My entire pot garden outside my house got wiped one year - the flurry of outrage, mouth foaming and lurid threats resulted in a 6 week rent holiday....but still.

Thanks for the information..

If I am going to claim back my rose garden, this is a must for me right now...I only have well established roses in this area and they survived a trial last fall, and it made good headway on the overgrowth of everything I didn't want...

I will keep a section clear for planting in new rose bands.

Please note, the article quoted above from the Arnold Arboretum was published in 1969. The Arboretum has not used this herbicide since the early 1970's. The article is not meant to be a recommendation for use of Caseron today.
