Interesting:- Looks like JI ericaceous is similar to JI seed compost
.The difference is that limestone is replaced with sulphur to give a
higher pH.
I have never used JI but I suppose perhaps I end up making something
vaguely similar by mixing soil with bog standard seed and potting
compost.
Make that a LOWER pH. pH7 = acid pH7 alkaline. p stands for 'minus
logarithm to the base 10', and H the concentration of hydrogen ions (if
you are interested). So the higher the H+ concentration the lower the pH
Woops and me an ex Khemist. Thanks.
Always though pH meant potential for hydrogen?
