theres a thread specifically for this search tool is there for a reason
no decaf, instant or flavored coffee if at all possible. lance's steps are right on. the coffee can sit in the soil for longer than a day but you def want to make sure it gets rinsed out in under a week. i just let the following watering do the rinsing.
I hate to think what could happen to my Nepenthes fusca if I watered it with coffee. Does this actually work?
