Does 'RoundUp' work on ALL plants?
I want to get rid of moss & lichens on my slate roof. Also does it kill
bacteria, which are plants evidently? |

I think Roundup is overkill for all of these. Not to mention that the runoff
onto foundation plantings would be sure to create a disaster. Pool chemicals, Porch & Deck cleaners, and Clorox would be easier, safer and better to use than Roundup (not to mention one heck-of-a-lot cheaper). The moss will still require a stiff brush to get it off the slate once it's dead by any means. It doesn't just let go and float off with the next rain. Leaving the dead moss there is just making a nice fertile place for new spores to germinate once conditions return to normal (after a few heavy rains). Regular spraying with any of the above will insure inhospitable conditions. Use pool algaecide at about 1-2 Tbsp/gal; clorox at 5-6 oz/gal; porch & deck cleaners come in spray bottles ready to use or dilute concentrates according to the bottle. An easy way to do this would be to buy a hose-end proportioner where you fill the bottle, screw in onto the end of the hose, and spray your roof from the ground. Make sure it can reach that far before buying it. Gary "Peter Jason" wrote in message ... I want to get rid of moss & lichens on my slate roof.

Thanks. I do know about the Clorox method and the other which is the
application of C12 quaternary compound (supposed to leave a retardant film on the slate surface), but the only reason I have not tried these is because I fear my gutters corroding. But I will try the Clorox method after the Roundup (applied yesterday) works or not works. ncidently I have just had my drains routed for roots (there were plenty) and the plumber said that the terra-cotta drains were cracked and that I should flush some copper salts down the toilet to dissuade future root infiltration. Before the plumber arrived and while the drain was still backed up I emptied some Roundup into it in the hope this might kill a large length of root. Anyway, now I have a bag of copper sulfate next to the toilet and I throw about half a kilo down the bowl twice a week followed by a half flush. Do you know if this sort of thing works well?

Copper sulfate is the best thing for roots in the drainpipe. It does work, though it's illegal in many places here in the US. Marine life is highly sensitive to copper and since treatment plants don't remove it, so keep that in mind and don't use more than necessary. I think that Roundup has to be applied to green leaves and activated by sunlight. I doubt it did anything in the drain. My parents lived on the Pacific coast and had a big moss problem on their roof. My dad used rock salt and said it worked well. |

My dad used rock salt and said it worked well. I have had a lot of luck killing the green moss that grows on old concrete in damp places. I mix denatured alcohol and water 50/50 and just spray this on when the surface is dry. It kills all within a week and leaves the concrete 'bleached' white. Perhaps Vodka (neat) would work too. |

You probably don't need to use that much copper sulfate at a time, and I would suggest checking with your local laws about dumping Roundup down the drains. Here in the US, it is illegal to do that.

Jeys disinfectant fluid kills moss. Mix as directed on the tin.
