    Didn’t get in time

    My shipment took longer than expected and I needed this to save my blueberries. I’ll try this again next time

    Blueberries are happy!

    My potted blueberries respond well to it as soon as I start feeding them with this every spring, and top with some Biodynamic compost, then a little mulch.

    Good Fertilizer

    Blueberry fertilizer is not available in my small town. Fertilizer seems to be feeding fine.. Shipment arrived as promised and packing was sufficient. I'd order in the future from Grow Organic. Recommended.

    Blueberries

    I added this to the soil that I planted my new blueberry bushes in. I won't know how well it works for awhile, but I sure hope it does!
