I rescued this girl off the curb in my neighborhood along with a couple other plants. She’s my first monstera adansonii. She’s very leggy, so I’m assuming I need to completely clean off the old dirt she’s in now (looks like a basic potting soil), remove the dead stuff, and do some chop and pro with her. What soil do they prefer? I also think she probably needs a slightly smaller pot, but I’m not sure how big the root ball is until I get her out of this one and see.
