Iâ€™m really interested in starting my own vegetables from seed this year using soil blocks. But Iâ€™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. Iâ€™ve also been told to find another source of potassium because greensand takes too long to break down to be effective for the young plantâ€™s needs, but I am doubtful of this information. Can you give me any advice? Get the answer Â»
