I have space in my fruit pen, and would like to grow some blueberry bushes. The PH in the soil however is 6.5. How can I lower it to the required 4.5

I have read that its very difficult to permanently lower the pH. If you are set on growing them in the ground rather than a half barrel I would replace the soil over as big an area as you can spare. Possibly add some gel crystals as they need constant moisture.

Digging in soil sulfur crystals will produce a zone of the proper pH around each crystal. The roots will draw their nutrients from that zone, while you apply compost twice a year to gradually lower the ph over the entire root area.
