Hi to all

What would you recommend as a high potash fertiliser for citrus
trees? Thanks
Sandra

Chook poo is good for citrus but it is not high in potassium. If you are
sure that potassium is required then the quickest and cheapest source is
potassium sulphate. You can buy a 500g packet for $8 or 20kg sack for $40
(IIRC). The sack will last a very long time. It must be applied sparingly
and well watered in. I wouldn't be applying it until spring.

Despite being synthetic potassium sulphate is an acceptable input according
to organic standards. If you picture "organic" meaning synthetic fertiliser
is bad then there is no logic to this at all. The reason is most likely
that there are very few non-synthetic fertilisers that are high in potassium
and most of those are ash which tends to be very alkaline.
