I've been growing a container garden on my deck in Boston for a number of years. In getting my supplies for this season, I was told that I could mix my potting soil with peat moss as a way to reduce how much potting soil I would have to buy. I used a 30/70 peat/soil mix for each container (there are about 30) and have noticed that my Asiatic Lilies are not doing so well. My mom had said that she doesn't use peat in her garden as it has an effect of making the soil acidic. Thoughts?
I'm in a bit of a panic because I find so much serenity in my garden during the summer months. I'd hate to realize that I did my plants more harm than good in mixing the soil with peat.
