Is Conifer Pine Mulch Toxic or otherwise bad for the garden?
Hi there,
Its Autumn here in Melbourne, Australia. I have a row of conifer pine trees - medium size - dark green leaves. They are about 6 metres tall and are due for a good prune back. I believe they are called Castlewellan Gold. They don't have seeds, drop many leaves but they do grow. Here's a link to a photo. http://www.ballarat.net/avalon/cypress.htm I thought of lopping off the top of the trees- mulching them including the leaves finely - and then using them as mulch for my rose garden. I'm allergic to the pine leaves so I'm getting tree pruner to do the job. One old grizzled tree pruner however warned me that using fresh conifer pine mulch was a very bad idea and will kill the roses or any other plant. Is using conifer mulch for the rose garden a bad idea? I didn't realize it was toxic. |

However composted for a years was greatly helpful if applied correctly. Do not use fresh chips. The protoplasm from the living parenchyma cells gets smeared all over the place and attract undesirables that can and do do nasty things above as well as below ground. Compost them in a pile for a years and then here are mulching suggestions based on tree biology. http://www.treedictionary.com/DICT2003/M/mulch.html One old grizzled tree pruner however warned me that using fresh conifer pine mulch was a very bad idea and will kill the roses or any other plant. It is a bad idea. One I used once until my professor in tree biology that was a mycologist stooped me. Is using conifer mulch for the rose garden a bad idea? I didn't realize it was toxic. Not if you compost it for a year or more. The longer the better. -- Sincerely, John A.

You could add reasonable amounts of ammonium nitrate (AN) (fast release nitrogen fertilizer) to the chip pile and that will stimulate the decay fungi. The things is that once the contents (protoplasm) of the parenchyma cells is no more, the problem is over. The faster the wood chips decay probably the faster this happens. AN does have the potential to pollute ground water so please go lightly. Also adding a little water and turning the pile form time to time will help. The micro we are concerned with are those that attack defenseless cells. Usually when you start to get that good earth smell and the color darkens you are alright. I decide by smell. -- Sincerely, John A.

Another person might tell you that using fresh pine chips invites artillery fungus which is also called the "sphere thrower". Usually pine mulch will simply lower the pH of the soil, making it more acidic. If you are only using pine chips from your own trees, it is probably safe to use it. If there is a problem with artillery fungus,"sphere thrower" fungus, in the area then it is best to avoid it. Secondly, any chemical fertilizers will kill the natural, and desired, micro flora and fauna in you soil. Use fish emulsion or some other organic source. -- Billy Impeach Pelosi, Bush & Cheney to the Hague http://angryarab.blogspot.com/ http://rachelcorriefoundation.org/ |

My garden is mainly clay soil. A bit of pine mulch would probably do it good. The trees look pretty healthy to me. Green, strong, no sign of yellowing, any more healthier and I think that'd get up and walk. I don't think they suffer from any disease. The latest tree pruner suggested placing the mulch in a seperate part of the garden which is hidden. We'll do that and keep it there for awhile til its safer to use. |

I agree 100% The more composted the wood chips the less likely you are to get artillery fungus. Its associated with the parenchyma cells.
