Hello there!
I'm a proud owner of a somewhat large Daphne Odora which is beginning to
look sickly. The details are these:

Planted in amended clay soil in USDA zone 8
Morning sun, afternoon shade
Good drainage
About 7 years old

It grew well for the first years, and is now about 2.5 feet high with a
circumference of about 4 feet. Last fall, the leaves began to yellow.
It's blooming well this spring, but the leaves have lost almost all signs of
green and there's very little sign of new growth. I don't see any sign of
sucking parasites.

Can anyone help my poor Daphne?

thanks in advance, skg
