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%
+ a few handfuls or more of fertilizer pending on size of mix.

Just look at how perfect this mix is.... homemade :)

    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
