Armandii - Leaves turning yellow - Help!!
james...@my-deja.com
but....
Every year after flowering 20% of the leaves turn dark brown/black and
die off, and the rest turn a rather sick looking yellow/green.
I know the brown leaves are 'normal', but is it all meant to turn
colour?
The flowers look amazing, but for the rest of the year it looks
terrible. Any suggestions? Is the soil too compacted, too dry, does it
need feeding etc.
Also I have seen posts that say that the armandii is very vigorous.
Ours certainly isn't. Any comments?

No.

I am not sure. I advise checking the drainage and/or applying
some Epsom salts. But those are blind guesses.

Not VERY vigorous, merely vigorous! Not a lot compared to
C. montana, but quite a lot compared to C. alpina. My guess
is that the chlorosis is the cause.

You don't say where the plant is? what should happen is flowers, new shoot
growth, old leaves go poorly and drop off, this is not normally noticed
because the plant is covered in new growth, since yours isn't, I suspect
lack of magnesium and or cold shriveling the new shoots, leaving you with a
mess!

If the most of the leaf is yellowish. Then yes.

Eh? BUT what is the cause of the chlorosis?
Iron lack can also cause bright yellow chlorosis as can potassium but
there is something basically wrong here.
C.armandii is a very fine and much sought after variety and it is very
likely that you have a bad clone. Since you have made no comment regarding
any trouble with other plants we can assume that the trouble does not lie
in the soil. Jennifer has just tapped me on the shoulder and asked if it is
possibly lack of water. I disregard her at my peril.
