I have this Phal since 2012., I don't know how old it was when I bought it. I repotted I think in 2013., and it looked to me like she SLIGHTLY overgrown her pot, so today I decided to repot her again. When I untangle her roots I was stunned how long they are! I had to repot in much bigger pot than planned
I'm curious, how big can it get? Show me your biggest Phals
There was a post a few years ago on Orchid Forum Orchid Care with some truly huge Phalaenopsis grown by a Vietnamese grower. On that site, search for a thread called "how to plant the Huge Phalaenopsis". It will knock you socks off.
