Hi All,
I have a passion flower groing in a largish tub outside. This year it looks
a bit yellow rather than the more usual dark green.
It is still flowering quiet well, but I'm wondering what might be causing
it. The leaves amd flowers are on the small side as well.
It hasn't been allowed to dry out, but I'm wondering if it's running out of
nutrients in the soil.
Are there diseases that could cause this effect?

Any thoughts much appreciated.
Thanks,
Matt
