Coffee grounds and slugs
Having been reminded that coffee grounds are a folk remedy for deterring
slugs, I looked it up online. Apparently it is illegal to use any untested product as a chemical deterrent. Mulching to add organic content is fine, though....... Ignoring the above for the moment, has anyone tried this and does it work?

Not especially well it is only mildly toxic to them and a bit too soft. There are other more spikey textures that snails won't cross so easily like crushed egsshells. My coffee grounds go on the compost heap. -- Regards, Martin Brown |

Check out the test done by James Wong, (him off the radio and TV) Conclusion was it in fact it inhabits growth, the coffee plant does not like compition, in the wild, so it stops other plants thiving close by. As for being a slug deterrent, check out you tube which has a vidio of slug travelling down the edge of a razor bldae, it travels on a bed of mucus, so notheing sharp is going to stop them, gravel, egg shells, etc, waste of time. There is another web site that has been running an experiment on various so called remedys, puts a slug in a ring of the material and watch if it can cross, nothing stops them. (ash and bran slows them down ) Also most slugs travel underneath the soil defeating a so called barrier. |

It modifies the pH a bit but I'd be surprised if it did much to slow growth of most plants - unlike black walnut which through juglone really does seriously affect competition by neighbouring plants. Caffeine in coffee is intended by the plant as an insecticide - it so happens that mammals find it an interesting stimulant. Cocaine and nicotine are more potent examples with the same intent.

There has been some research into it's use or more correctly the use of Caffeine. Turns out it is a good deterrent but in stronger doses than in grounds. http://news.bbc.co.uk/1/hi/sci/tech/2067214.stm -- Regards Bob Hobden |

In my garden, without slug pellets, in two days the plants would be gone. But I too am interested in their results as I would much rather not use the pellets if there are effective alternatives. |

It would be nice if they tested nematodes as a way of controlling slugs too. I did try them once, with little effect, though the requirements to be met for their application made it difficult. For instance, as I mulch there is little bare earth on which to operate. Chris -- Chris J Dixon Nottingham UK Plant amazing Acers. |

In no way would I ever knowinly falsely edit any ones post, and have not ever done it in the 20 + years I have been using this newsgroup. If I have made an error a simple polite correction would have been in order Derek From an independent observer's point of view... Janet's original post said (with my emphasis between the **):- "Pity they aren't including wood ash in the trial. When we had a woodstove I used to put a circle of the fine ash round individual brassicas and in rows between the strawberries, *which seemed to work well*." Your reply to, and including, her snipped post (again, my emphasis between the **): " Pity they aren't including wood ash in the trial. Janet Well they did, *and it was not a succes*, after all the slug rides on mucus, so most materials willnot stop them " Your reply indicates a direct opposite to what she had found when she tried wood ash. In addition, the BBC page made no mention of wood ash as far as I can see, so your use of "they" is misleading in that anyone reading it would believe it referred to the RHS trial. In any case, that trial has only just started, so if you know of someone who tried wood ash in another trial you are referring to, and if it was not a success, could you please post a link to it. -- Jeff |

I am not in the least surprised that most of the barriers were ineffective, especially when wet. The thorny barriers are interesting, but only really suitable for selected plants. I have wondered if ultrafine sand or silica sprayed in an adhesive gel which sticks to plants would dissuade slugs and snails from eating them. It would be a very hard material which could blunt the teeth on their radulas. -- Jeff |

Apparently it is illegal to use any untested product as a chemical deterrent. Mulching to add organic content is fine, though....... Ignoring the above for the moment, has anyone tried this and does it work? Yes it works. 3 years ago I put some slugs and snails on a piece of slate and added coffee mixed with grounds. The slugs started to dissolve :- https://www.dropbox.com/s/72kze5xc3x..._2206.JPG?dl=0 I popped a large pot over and investigated the following morning. No remains of the slugs but the 3 snails had climbed to safety, up the inside of the flower pot :- https://www.dropbox.com/s/lmub2irr51..._2215.JPG?dl=0 I'm not sure how much damage coffee does to the soil biology, I would therefore proceed with caution when using it as a general mulch. You need to get some sealed containers with some garden bugs and experiment with coffee grounds at varying doses. Getting hold of sufficient quantities of coffee grounds is straightforward as most cafes will donate, if you ring them beforehand. In fact, Howard Shultz former CEO of Starbucks started a "Grounds for your Garden" project. Wet "pucks" of coffee grounds are quite heavy, so double-bag for safety. The slugs' natural enemy are nematodes but it's probably beyond the scope of an amateur to test caffeine v nematodes. I haven't tested grounds on garden worms but the para "Ecological Effects" suggests it's Ok :- https://en.wikipedia.org/wiki/Coffee#Biology Your biggest hurdle will be protecting your barricade of coffee grounds from heavy rain. Constant topping-up, could turn your hosta patch into a sterile desert. One of the Hawaii universities started a study (about 10 years ago) on the bio effects of coffee in the soil. Maybe they ran out of money but so far nothing has been published. Anyhoo experiment, proceed with caution and .... good luck. |

Maby you want to get your coffee grounds from Costa, then the multiplicity of coffees available would confuse the slugs so much they would forget what they came to your plot for. I know it confuses the hell out of me. |

I was told a long time ago that there are certain plants that slugs don't like to eat. if these could be identified then perhaps they have a chemical in them that might make an effective deterrent? |
