I love these informative graphics from fix.com. I make my own potting mix, so I like this one especially.
What’s great about making your own mix is you can adjust the mix for your plants’ needs. Potting succulents? Add a little more vermiculite or perlite to the mix for the extra drainage that succulents need.
The recipe below calls for worm castings which are a great source of nutrition for plants. If you can’t find them, though. No worry, use a good dry organic fertilizer instead. You can find one here, at The Herb Cottage. (Scroll down the page for the dry, compost based Fishnure.)
