New growth turning yellow....

gssgarden · May 15, 2009

Seems like the new growth has a strong tinge of yellow on it. Might, and I say might have had a little early blight but they were sprayed a few days back. It seems to be effecting all plants in raised beds.

Any ideas? You think it's a nutritional deficit?

Pic is on the way once I figure out how to re-size them.

thanks,

Greg

Iron deficiency maybe? You can usually still see green veins
in the new leaves that are beginning to develop it. (Nitrogen
deficiency starts on the lower leaves.) Has it been raining a lot?

A picture (iron deficiency is down near the bottom of this
document):

We routinely get it out here when someone gets too close to
a rhododendron or azalea with the lime or wood ash (pH too
high for plants naturally adapted to acidic soils).

Greensand is a good source of iron, but it is in the form of a rock
(glauconite), so it is slow release. Fine if you amend your soil
with it in fall or in spring the year before, might be a little too
slow for a quick fix.

Fertall markets a couple of chelated iron treatments, one
a powder with 4% iron and other minerals that costs $2/lb
in a 50-lb bag, another one a liquid:

(It could be some other deficiency, of course, with similar
symptoms. Iron is just the most obvious guess for symptoms
seen first on new growth.)

Wow. Thanks Dice. It looks very similar to that. The only difference is it's in the new growth only and seemed to have stopped there. It mentioned that the whole leaf would turn white. Have not seen that but it's pretty darn close.

Thanks again, I'll look into it.

I have had that problem, but I have never seen them turn
completely white myself (perhaps because the soil was just
deficient enough for the plant to show it; it was getting some
iron, just not enough).

I don't know when you planted them out or your weather conditions after they were transplanted so can't really tell what's going on. May not be a nutritional deficiency at all but just "transplant shock" which will most likely correct itself with time & more favorable conditions for growth.
Wait 'n see.......
