After the deaths of a few store-bought catnip plants, my parents mail-ordered me some seeds for Christmas. I left most of the sprouts at home (why I thought planting 100+ seeds in two 3" pots was a good idea, I still don't know) and brought the most developed plants back to campus with me.
I was wondering if there were any ways to spoil my catnip plants more, and if I need to pluck them more or not. If it matters, the window I'm growing them in is west-facing, and I'm a heavy tea drinker, especially mint tea, though I'm otherwise limited as far as possible fertilizers go--I am sharing a room with these plants, so I can't have anything rotting in there, lol.
Also, I've noticed that despite being from the same seed packet/bred strain, my two largest plants have taken on different growth patterns--one seems to grow shorter, with well-defined veins on its leaves, and the other has grown upwards more, with flatter leaves. Are they secretly from different plants, or are the pots/foot difference on the windowsill able to affect their growth this much?
