Multipurpose Compost. Johnathon is feeling unhappy because no one is posting questions today so how about this one on multipurpose compost.
At different stages of growth plants need different strength compost - you can't feed a baby on steak and chips any more than you can feed a man on milky pap. We sow seeds in a seed compost that is very low in nutrients, pot the seedlings on into something slightly stronger and the grown plant into something stronger still.
Because I am not happy with the John Innes seed composts currently available I have been looking for alternatives. The pictures illustrate just one of many similar multipurpose composts from the garden centers. The packaging gives exactly the same instructions for sowing seeds, rooting cuttings, potting on and for growing mature plants. How? I am using it for seed compost - it is a humus rich compost so I can shovel as much grit and coarse sand into it as I want and this will also weaken the strength of the compost. But I would still like to know how you can produce a 'one size fits all' compost for plants.
