Does disease remain in pine needles?

Q&A

Our subdivision manager finally had a dozen dead Scots pines removed this past week, many of them just over our property line in the common area. There are loads of pine needles left behind, and if they were safe to use, I would LOVE to collect them to use as mulch. I know the wood must be destroyed, but what about the needles? And would they be suitable for use around some plants but not others? - Gugsi -

    I am assuming since the pines were Scots that the problem was Pine Wilt that killed the trees. If that is the case than the needles are not a vector of the disease. The issue with Pine Wilt is the beetle which plugs the vascular system. The needles are just fine. So go ahead, rake and use as a mulch.

    The other issue is if the pines died from a foliar disease. Than the needles would contain the disease which would only effect other pines not other trees, shrubs and flowers.

    In this case if all the pines are gone no problem. But if there are healthy pines in the area the needles could transmit the foliar diseases.

    Great, thanks! I had a feeling the needles were more the victims, choked off by the vascular disease, but I thought it wise to double check. Woohoo! Pine needle mulch for me!
