I’m really interested in starting my own vegetables from seed this year using soil blocks. But I’m finding quite a disparity in the basic “recipes” for soil block seed starting. They generally involve peat moss, soil from the existing garden, perlite, lime, compost and a fertilizer mix of bloodmeal, greensand and rock phosphate; but they vary. Some omit the garden soil, some omit the lime, and the amount of the fertilizer mix can vary greatly from recipe to recipe. I’ve also been told to find another source of potassium because greensand takes too long to break down to be effective for the young plant’s needs, but I am doubtful of this information. Can you give me any advice? Get the answer »
