I have one fuchsia plant in the yard, remains mostly in the shade for about eight months and gets sun for about four months of the summer. The leaves have been turning purple since last Nov/Dec. The leaves were not so purple last year around the same time. In Dec 2017, all leaves were uniformly green and there were at least ten times as many blooms on it.
Is this a sign of missing nutrients like phosphorus or just a normal winter condition? This plant has been in the same spot for many years.
