I picked up this little Thai Con at Walmart for $25. I tried to get them to mark it down more because his two biggest leaves had snapped and were hanging on by a thread, but the cashier wasn't having it. So I took him home anyways and cut off the broken leaves, treated him for pests and repotted him. This is my first monstera and I'm worried I've already made some mistakes. I plan to change the substrate soon, after learning how prone they are to root rot. I did mix the potting mix VERY heavy with pearlite but I fear it's not enough. I plan to repot in LECA once I get my hands on some. I think the pot he is too large as well. He is getting filtered light from both an east and south facing window. Any thoughts/opinions on what else I should do/change to be successful? It's taken me a lot of courage to get a plant with this much potential. My gateway plant was a moth orchid followed by calatheas and other various tropical dudes. Should I wait to change substrate since I just repotted him? I'm just so anxious about the root rot. Thanks in advance for any advice/opinions.
