Planting out seedlings - now I have slugs
Comments (20)Here is a cheap and easy way to eliminate slugs. Mix equal parts clear ammonia and water in gallon jug. Add 2-3 tablespoons of Murphy's oil Soap, mix and pout into spray bottle. Go out after dark with a good flashlight and spray mixture right on the little buggers. They instantly turn to slime and die and fall off plants. There is a lot of satisfaction with this method. I have reduced the slug population to almost nothing using this spray. The ammonia will not hurt plants, mixed with water, it is almost pure nitrogen and really makes the hostas green up. Do this for 3-4 nights in a row and then couple times a week after. In the fall, be sure to check the grass. We found that's when they are out "making whoopie" for new babies in the spring. We had them so bad a couple years ago, DH mixed this in a 3 gallon sprayer and would use it all in one night. My Grandson loves to say on a warm evening, "Hey Nana, lets go hunt slugs. The Murphy's oil soap will remain on the leaves and when those baby slugs you see eat the leaves, it will give them a fatal case of the trots. Just what they deserve! I have used beer traps, but found this to eliminate them much faster and I don't have to dump the dead slugs out....See MoreDoes 2-3 feet of dead leaves harm sleeping hostas?
Comments (8)the issue is whether there was any air available under the leaves ... heavy dense leaves can cause an anaerobic layer.. where no air moves in or out.. causing everything below it to die .. and boy will it stink ... think rotting swamp gas ... e.g. ... if you can kill grass under a pile ... then a hosta wont live ... one clue would be whether you see any evidence of anything growing under the pile ... maple leaves are killers .. if left intact.. oak should be ok.. since they dont compact to a slimy heap of gelatinous goo ... then you move on the whether the soil under 2 or 3 feet is even thawed yet.. or warmed enough to initiate this springs growth .. and then ... move onto whether a 2 foot hosta has enough stored energy to reach 3 feet above the leaves ... if you dont remove the leaves ... safe to say.. it wast the best thing to do .. whether or not yours will return.. shall be left to the fates.. let us know if it pops .. ken PS: now if you had done this on the driveway .. lol ... the leaves would have eventually blown away.. and the hosta would have surely have survived.. lol .....See MoreUsing ammonia to kill slugs
Comments (7)Ammonia is a contact poison for slugs, you must spray any slugs with the ammonia to kill them. It has no residual affect on the slugs and once the ammonia is dry it will have no adverse affect at all. Pouring undiluted ammonia onto plant leaves could harm them and is not something that should be suggested. A good control for slugs is to spray your Hostas with cold, caffienated coffee as often as necessary to keep the slugs from them. The cold, caffienated coffee is a slug repelent. Stale beer placed in shallow saucers around the garden will attract the slugs and they fall in that beer and drown. Iron Phosphate pellets can be purchased and scattered around the garden and that is a poison that alos kills the slugs....See MoreWill the bleach from pressure cleaning the house harm plants?
Comments (4)I have had a professional (Belle Mead Painting and Power Washing co.) "soft" power wash our deck every other year. They have an enclosed trailer with multiple 2-300 gallon containers of water and bleach. He has several power buttons on his "power" handle. He gives all a quick water-only spray to begin, then moves to the bleach/water mix (he controls it) and cleans our flooring and the white railings, they look bright white, like new when he is finished. And, fyi, his final rinse is all water again. I have lots of different types of shrubbery around the decking, he has told me again and again, it will not harm. He is right, in the past 6 yrs (just had it done a month ago) the job is very well done, and it has never harmed any of our plantings! Get a pro!...See Moreken_adrian Adrian MI cold Z5
