Potting medium for growing blueberries in pots

Asked July 7, 2019, 11:00 AM EDT

According to "Growing Blueberries in Your Home Garden" EC 1304, "A good planting mix consists of about 80 percent fir bark, 10 percent peat moss, and 10 percent perlite." Fir bark can be purchased in different forms. I've seen (for sale) fir bark shavings, fir bark dust, fir bark mulch. What should I look for?

Fine fir bark or fir bark dust would be best for containers. Or, if you have access to acidic soil (pH 4.5-5.5), you can use that instead of fine fir bark.

Thanks!
