hi everyone, i live near mindarie in perth, where there is lots of
limestone. i was just wondering what others in a circumstance wehere they
live on almost a limestone pad, do to combat the alkalinity? any tips?
currently i put trace elemets, iron chelets on. but i dont know if i amdonig
enough. the grapefruit tree i have, still has green veins and yellowing
leaves. not sure what to do. how long does it take after adding back
nutrients to u notice a change.

and, what fertilizers does everyone use?

thanks in advance
