My question is about a property I own in zone 4b. I have a patch of Nettles the stinging ones that grows in a Strawberry and fern area. When is the correct time to put weed killer such as roundup on them? And is there a kill product that would not kill the other plants in this area?

I usually suck it up and pull them out with thick leather gloves. I'm not sure, but I think they're perennials? So pulling would be really effective, especially if you don't want to hurt the strawberries and ferns, (or eat Round-up residue, ick). Be careful, though! Supposedly it's only a "seven-minute-itch", but they really make me break out. Good luck! (10/22/2007)

Thanks Beth. I have done that dig up thingy several times and they continue to return. From what I have read yes they are perennials, but they also have a flowering seed that lies in wait. A good time they have said to pull them is while they are short. Only I have found that even digging up the whole roots does not help. Seems they have a habit of growing where nitrogen is high levels and this is cause by feces from animals. So beware if dogs and cats frequently use your yard as a littler box; you may have nettles. Now why the nettles don't bother them is another question? (10/22/2007)
I put Roundup on my stinging nettles when they were very tall, and it killed them quite effectively. Now I don't know if they are totally gone, because sometimes with perennials, you have to use Roundup several times before it kills the root. The best time to kill them would be when they are small and young, as they are not so robust then. I don't think you need to worry about eating Roundup residue. If you get it on any plant, the plant will die, and so you will not be eating it. It is not organic by any means, but sometimes it is the best choice for a noxious and harmful plant.
The stinging nettles is good for arthritis. Yes, I do know it does itch like heck. I found some in my back yard and I will let it grow. It is also good to make tea out of it. (10/24/2007)

The Roundup label says it is most effective when the plant is in a stage of active growth. If you want to apply it only to the nettles, paint it on with a foam brush (gloves, of course). The nettles keep coming back after digging because the life of the plant is in the network of roots. You can tell if another plant has Roundup residue if you see any dwarfing of leaves. I think the Roundup is your best bet to clear the nettles more or less permanently. Worked well for me, I had 28 acres of fenceline full of nettles and Roundup solved it. (10/24/2007)
If you truly want to be frugal, you can cook and eat them. I understand they are much like spinach, cooked. Wear gloves to gather, put in pot and cover with water. Boiling takes out the sting. (10/25/2007)
