I have a magnolia (victoria ?) that is a lovely evergreen but lately the leaves have a yellow, light green tone to them. Any idea what I can do to fix this and get back that nice dark green colour?
It appears that your Magnolia has chlorosis which should be treated with iron chelates. Magnolias appreciate fairly rich, well drained neutral to slightly acid soil. The chlorosis of your Magnolia suggests the soil is somewhat alkaline. A mulch of peat moss also should help. Good luck.
