[Arid_gardener] Fw: How often I add iron on my tree?

[Olin Miller]

I am not aware of a prescribed schedule for applying iron.  Some soils 
have lots of it.  Some do not.  Some plants need additional iron. 
Others don't.

If you are certain your tree needs it. you might begin with an annual 
application and increase the frequency if that isn't enough.

"Sequestrene 138 Fe" is one of the fastest acting powdered iron 
supplements, currently available as "KeRex".  If you want to use it and 
can't find it try calling Western Organics in Tempe to locate a retailer 
near you.

Ironite is perhaps the most widely available iron supplement.  Usually 
comes in a granular powder but is also now available in liquid form.  If 
you want to use it, you may want to also review the articles at

LABORATORIES

and

Sequestrene 138 Fe is probably faster acting, may show results in within 
2 weeks, but Ironite will last longer in the soil.
