This is the time of year many are starting their seeds indoors, and there are many growing mediums available. Some swear by ordinary garden soil, straight compost or the compressed pellets of peat or coconut coir – though I hear many in my local gardening groups with a definite hate on for the pellets!! Then there’s potting soil and seed starting mixes.

What to choose? Let a soil scientist explain!

I currently have two different brands of seed starting mix, because those were the ones available at the time I was there to buy them. So far, I don’t see any difference between them.
