I would like to grow strawberries, blueberries, camellia(Camellia sinensis) and a couple goumi(Elaeagnus multiflora) bushes in the same
garden bed. They are all acid-loving plants, luckily.
Could anyone tell me what peat:
compost ratio I would need to get to a pH of 5.5 for a raised bed? This would be assuming a
compost pH of about 7(Black Kow composted manure and Black Velvet
mushroom compost).
I use SFG for my annuals, and that pH is ~6.5. It's 1/3 peat moss(pH of 3). But since pH is a logarithmic scale, I'm unsure of the actual formula to lower it further.
