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?

Whilst we're talking passion flowers, what is causing the buds to drop on
mine? It's a young plant - just planted this spring and has only produced 3
buds. One has opened and is beautiful, however the other two have just
dropped off.

There's no obvious sign of insect damage - could it be over/under
feeding/watering?
