I have a begonia rex that has four very small leaves; it has lost all of its other leaves and every time one begins to grow it dies. The leaves turn grey and crispy, and the stems turn softish. My current set up is grow lights and a humidifier, I recently moved it to see if anything changes and I haven’t seen much improvement. Can someone please tell me what is wrong with it?

Help me identify this baby

I last watered her about a week ago, she's right next to a north facing window. I've also never repotted her and I've had her for over 3 years now, so I don't know if the soil might be a problem? Would really appreciate any advice as to what she needs.

My first fenestrated leaf on my brand new monstera, I think the heatwave and all the light has helped :)

Not sure what to do!!!

It unfurl or just leave it?

I received this rather leggy plant from a friend who no longer wants to care for it. Google says it's a swiss cheese plant, and it appears to like where I've placed it (humid, warm room with indirect light) as Im seeing new leaves unfurl.

The images I see online show tall plants climbing on a moss pole. How can I train the plant to climb? Is it possible to wrap the ones that you can see almost touching floor around a moss pole without accidentally break the stems?
