pH of compost too alkaline
Hi...just found this website and am loving it. I have a farm with horses and am a florist so grow predominantly perineiis (sp). I have spent the past 5+ years adding truckloads of leaf mulch and composted horse manure to my flower beds. I have done a series of pH tests and realized that the compost and leaf mulch are making my beds too alkaline. I would like them to be around 6-6.5 but they are now more like 7-8. This is way too high for growing peonies and dahlias (not to mention my blueberry bushes); so guess I need to amend soil with sulfer or aluminum sulfate? There is snow on the ground now so wondered if I could put some sulfer around the drip line of my plants. since my beds are already planted (not dahlias...they are out for the winter) Suggestions on the best way to amend the soil? Can't wait to hear back. So excited!
