Based on a previous post, I am going to prune my crypts. They have all grown HUGE and are curling over quite significantly in my 55 gallon tank. So here is a beginner plant keeper question-- What is the proper way to prune these long leaves? Do I cut all the way down to the base of the stem? Or do I just snip where the leaves meet the stem? Should I snip the leaves back one at a time or is it ok to take a bunch back at once? Pretty much the whole plant has about 10 leaves that are extremely long. I don't want to have these lush plants kick the bucket because I trim too much.
