I don't know who here has ever tried it but over a month ago I gave several different Nepenthes plants a single watering of straight black coffee I brewed in my regular coffee maker. The coffee "treatment" made a huge difference on every species I tried it on (rafflesiana, mirabilis var. echinostoma (6 different plants), x 'Maggie Jones' (one male one female), x 'Ali'i', x 'Roko', ventricosa x spectibilis, ventricosa x pectinata). The new growth is much larger than leaves produced immediately before the coffee treatment. The color change was nearly immediate, within a few days the old leaves turning a much darker green as well as new leaves, and the pitchers themselves have darkened up drastically. New pitchers are much larger than the previously produced pitchers. And growth speed has also accelerated over the weeks following the coffee treatment.
I've been using MaxSea 16-16-16 for a long time and I plan on continuing to do so. I've also used Better-gro Orchid Fertilizer (Urea Free). But a one-time watering of coffee has made a much bigger impact than MaxSea has ever made, and did not burn any of the plants I tested it on. Don't get me wrong, I think MaxSea is a great fertilizer to use at regular intervals and I'm going to continue using it the same way I have been. I don't think this coffee treatment needs to be done very often to have lasting effects. I also believe one the major benefits of using it is the acidifying effect it has on the soil, and therefore subsequent treatments may not have as much impact as the first.
I top-watered with just enough to have a little dripping out of the bottom of the pot. Two-three days later I watered like normal and have been since that time. Nothing else to it.
I highly recommend trying it.
