FlytrapCare Carnivorous Plant Forums

To help many people; remember, in all things, moderation.
Osmocote (for Neps) and Maxsea (for almost every other carnivorous plant) has been tested by use many times over.
To that end, if you're unsure, use moderation. Put a single Osmocote pellet into a single Nep pitcher to gauge its reaction to chemical fertilizer. The pitcher may die, but see how the plant reacts.
Put a single droplet of 1/4 tsp of Maxsea to one gallon distilled water on a single sundew/Pinguicula leaf. Or a single spritz of solution on a Flytrap/other CP. Or 5 ml into a single pitcher of Sarracenia or Cephalotus. See how the plant responds.
If the plants response isn't what you want, then use the rest of the chemical fertilizer (Osmocote or Maxsea) on your lawn or garden, and let the plant catch its own fertilizer.
Realize that the plants reaction will take months to come to fruition, but may actually be more than a zero sum game.
In my experience, early Spring chemical fertilizer will give a boost. But late Spring/early Summer bugs will be more beneficial. A late Summer/early Fall boost of chemical fertilizer will be nice, but not necessary, as they will have more than enough to see them through dormancy.
