this is not really anything new but i did not find it specifically explained anywhere and i thought i would share.
My terrestrials all have the same problem, weeds. things grow fast here and the weeds are the fastest. I hate weeding in the pots where orchids live bc i am a root puller and i dont like to hurt orchids....as a result i clip the weeds and they come back.
so a while ago i started this .....i fill the top of the pot with LECA i dont like, in this case CRUNCH, has been used to dress the top of this phaius about 2 inches deep (in most places...some are a lot less). as a results the weeds dont really take as quickly and, much more importantly, they can be pulled effortlessly without bothering the soil or plating mix below.
