Make your own Potting Mix

I rarely buy bags of potting soil from the garden center...I just make my own using a few simple ingredients.
Start with compost, add peat, perlite and fertilizer and mix well.
You can buy a big bale of compressed peat and large bag of perlite, depending on how much you need, these could last you quite a few seasons.
The fertilizer could be a slow release formula or a generic all purpose. I add more fertilizer depending on application ( hanging baskets for instance would get a handful more at planting time.
I just get in there with my garden gloved hands and give it a good mixing pulling out any large pieces that need more time to cook in the compost.
Your ratio should be about:
Compost= 60%
Peat= 30%
Perlite=10%
+ a few handfuls or more of fertilizer pending on size of mix.

    what type of fertilizer do you recommend for perennial flowers. I live in Zone 6, Boston area. In the process of making a slope into another garden but want to admend the soil. I removed the grass. I have sand in one large area.

    I've been reading lately that peat moss makes your soil more acidic. Do you use that in ALL your potting soil for all your plants?

    I can never generate enough compost. I end up buying more

    It may be different in the UK, but many of us here are buying peat-free compost/fertiliser because of sustainability issues Lindsey Kushner, Manchester, UK
