Iron fert

[druss]

Im thinking of mixing this in with my potting mix for my iron hungry plants, like jabos.

Any thoughts?

i just got some "Chelated Iron DTPA 11% 1lb"
and a pound of this stuff is cheap, and goes a really long way.
it acts very fast too.
within a week i saw a few plants green up the leaves.
i have enough to apply it several times per year, and last a couple of years.
but i dont know how long it sticks around in the soil after applying.

about 6 months ago i had bought plain iron sulfate
which worked OK on a couple of plants
(works pretty good as a foliar spray)
but it acts much slower in ground.


i kind of like my approach of having both
both were  pretty cheap ...
but Osmocote usually has good products
and it looks like an easy long term solution.

you can read about the different types here.

some fertilizers can interfere with iron absorption.

How much iron powder per gallon are you using?
I have some 10% Chelated Iron powder I was planning on using this afternoon.
Thanks.

Thank you for the good links.
