Q.Aeonium stem drooping
An Aeonium I cut the top off last year to encourage branching, produced 3 new branches and grew well but one of the branches has suddenly started to droop as if the stem is not strong enough to support the rosette. What could have caused this and is there anything I can feed the plant to encourage strong stem growth? In fact, what is the best fertilizer to use for Aeonium schwartzkopf?
This is very common for leggy branches to become heavy and droopy.
You can remove the stem and propagate it.
