Hi,

I freely admit I have been neglectful - not pruning the Wisteria to
keep it
on the straight (or fairly twisty) and narrow.

However it started the year with dark green foliage.
As the year progresses the foliage is getting lighter and lighter
and now is
mainly pale yellow/green, although the Wisteria is still growing
fairly
strongly.

I would put it down to lack of nutrients, but when on holiday in
France a
few years back there was a Wisteria in the yard of the Gite which
showed
similar symptoms, and giving it a liquid feed or two didn't seem to
make any
difference.

So is this a natural thing, perhaps easing back on the chlorophyl as
the sun
gets stronger, or should I feed the poor thing with massive amounts
of food
to get it green again?

Cheers

I have always assumed that that's the way they grow, My new growth is
also very pale.......

Well, I decided to experiment and I have been adding large amounts of
Growmore around the roots of the Wisteria where it is planted in a 'removed
paving slab' space in the patio, then washing it in with copious amounts of
water.
Probably not the correct way to feed a plant.
However the results are interesting.
The leaves which were pale yellow are now gradually returning to a darker
green.
First the veins in the leaves turn green, then the rest of the leaf greens
up as well.
This sugests that the plant was being starved of nutrients, although it
still seemed to grow strongly.
I guess I will have to stop feeding it fairly soon, or I will be in danger
of encouraging too much sappy frowth late in the season, but it will be
interesting to see if it flowers any better next year.
