Hello Moon Hawk,.
The Bonn experts fertilize 1 x per week super with 0.3% Wuxal
(N + P + K = 8 + 8 + 6), in the winter every 3 weeks.
For home use, it is important that is fertilized at all. It is safe
each Grünpflanze fertilizer, the cheap Pulle from the grocery store
suitable.
I myself am usually Flory 3 (15 + 10 + 15) or Hakophos special ()
16 + 8 + 22 + 3) or just in the summer of Flory 1 (20 + 5 + 10 + 2).
I dung tickets at each casting with 0.07% (0, 7 g / L Gießwasser) or, if I
the forget accordingly even with 0.2%.
The Bonner still suggest that set the fertilizing course
will, as soon as the tide begins to turn yellow.
Nutrition is the new paper started again, once almost the whole
is unfolded.

In the mountain Garden in Hanover will be fertilized at each irrigation. In addition is a long-term fertilizer (Osmocote) in the upper layer of substrate "incorporated".
Happy feeding,
