is it any good on wicken grass ?????
Wicken is something that some of us refer to as couch grass, and it has a lot of other names too.
Roundup gel will kill anything that is green and growing. When a few people say that it doesn't work, that is because they have not followed the instructions, or have not read the numerous posts on here saying that it takes a long time to work, and are being far too impatient. If you want to do the job properly you need to be patient.
I've tried this product on several different plants, ranging from brambles to reeds, and it has always been successful.
I haven't actually used it to get rid of couch grass, but I believe that it would work. The difficulty would be applying the product to the individual stems of grass. This could be done by resting a stem against the palm of a gloved hand, and brushing the gel onto the stem using the free hand (that's how I applied it to reeds). It would be very tedious if you have a lot of couch grass, but it will succeed.
The speed that Roundup works is dependent on sunlight levels and growth rates. Now would not be the most effective time to apply, but you could still give it a try.
