Forgive my noobishness, but how do you...
Make your carpets and other small plants actually stay in the substrate when planting?
I've managed to kill a couple batches of hairgass and some small stem plants because I can't get the dang things to stay in the sand! I've tried both fingers and tweezers and can stick one in but as soon as I let go it just floats right to the surface 4 out of 5 times! The ones that do stick end up coming un-stuck due to me disturbing the water planting the rest. I've tried planting with a low water level too and they all take off like rockets as soon as I add water.
They make it look so easy on YouTube. What am I doing wrong? Are small plants a dirt-only thing?
