A. You have a great selection in a mid-pride peach. Honestly,
I don’t see a whole lot wrong with it. The leaves are yellowish but this is not
due to iron. This is actually some sunburn and discoloration to the leaves.

The difference between iron and
bleaching by intense sunlight is in the coloration of the leaf. When a leaf is
discolored due to high light intensities or sunburn they tend to bronze in
there yellowing. This bronzing is over the entire leaf.

Yellowing due to a lack of available
iron in the beginning stages of the leaf’s growth causes the yellowing to occur
between the veins of the leaf, leaving the veins a darker green color. The term
for this is in interveinal (between the veins) chlorosis (yellowing).

As the lack of iron intensifies, the
yellowing between the veins becomes more pronounced. As the iron problem
worsens more, the leaf begins to scorch around the edges (it is unhealthy and
cannot handle stress as well) and the interveinal chlorosis progressively gets
worse. At some time, and in some species, the entire leaf may become totally
yellow with scorching on the leaf margins and the veins only with a hint of
green in them.
The best type of iron chelate for us
is also the most expensive one. But a little bit can go a long way. The only
place I have seen this for sale in retail packages in small homeowner
quantities (one pound) has been at Plant World Nursery in Las Vegas.
