| I have always wondered, is it better to use cedar or pine bark mulch for raspberry plants? They say that pine bark is somewhat acidic, but some say its acidity is negligible. I know that raspberry plants prefer acidic soil, so adding elemental sulfur would help. But is pine back a better choice? A bag of pine bark mini-nugget mulch cost 4 times more than a bigger bag of cedar mulch. Is it worth paying more? |

| If you're looking to acidify soil pine bark will not work that well. So use either mulch. Fertilize with holly-tone, or use cottonseed meal, or use sulfur to acidify, All three will work. |

| Many consider cedar etc. as allelopathic. If your not familiar with the term you may want to look at this article http://edis.ifas.ufl.edu/hs186. Until recently I would not use cedar chips at all because they come with complications such as will my apples get apple-cedar rust? are they mildly toxic? etc.. One of the latest papers published suggests the wood chips from cedars are in fact not allelopathic. http://www.puyallup.wsu.edu/~linda chalker-scott/horticultural myths_files/Myths/Allelopathic wood chips.pdf . In some cases certain plants are affected by allelopathic plants and others are not https://pubs.ext.vt.edu/430/430-021/430-021_pdf.pdf. Either wood chips should be fine. |

| I doubt raspberries would be bothered by cedar. They scoff at black walnut, you can grow them around walnuts no problem. I don't know of any problems with allelopathic plants and raspberries. |
