Hi Tracey,
Iron chelates should rectify the problem with the chlorosis in the leaves. But knowing Mindarie there is a lot of capstone below the surface. My suggestion would be to either put an azalea mix from your local garden centre as a mulch or visit the Yanchep pine plantation and gather some pine needles both are acidic. The pine needles are an excellent mulch and break down to a nice soil. Top ups would be necessary as it breaks down. Added bonus is less weeds. Now just bud an imperil mandarin and a navel orange onto the tree as they are so much nicer than grapefruit!lol Cheers Richard "tracey" wrote in message ... 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 tracey |

I'll have to think about that one! thansk again tracey These wont be any good untill you can stop the soil going alkaline. The problem being food uptake which cannot happen if soil is acid. (acid for Azealias) Better to put it in a small mound of mountain soil or such, (a tub?) Azealias come from mountain country and need constant running acid water. Try tea dregs/leaves at regular intervals .It works for me. PS position face south away from midday sun and keep cool too, helps. |
