    I have 2 blueberry bushes growing in the back yard. The plants are about 20 years old and have always been good producers.

    I also have a neighbour that has spruce or fir trees which drop needles on our property all year (which is doing a number on the lawn). I have read that as needles break down they produce an acidic environment and blueberries like acidic soil.

    Questions:

    Would it be okay to use the needles I rake up as a mulch around the blueberry bushes?

    How deep can I safely pile these needles around the bushes?

    Thanks,
    Anne

    On the surface, I can't see a problem with what you are proposing to do. Are you trying to correct something, though? Or just wanting to experiment? If something is succeeding (as it sounds like it is for your plants), sometimes it is best to leave well-enough alone.

    It's more a way to keep the weed down around the bushes and also to find a use (other than garbage) for all the needles the neighbour's trees shed.

    Since Blueberries like acidic soils I suspect it will not hurt at all. Give you the weed blanket you need and keep the soil composted. Probably would not hurt to put a bit of bone meal down for each plant first to keep the nitrogen cycle going.

    Here is a bit on fertilizers and mulching
