Hey Harvey, I also have a pretty Yellow Bird but it has to do some years of growing to reach the size of yours!

Harvey, is your plant mounted?

Hi Jane. Look at the first picture you can barely see a few parts to a wooden basket. It is a pot in a basket that overwhelms the basket. I let them keep going as they are as long as it continues to be vibrant. Usually I will repot when the wooden basket starts to rot or the wires rust through. Otherwise I like the plants to get big. Sometimes after a while there is no growth in the center and growth only coming over the sides. At that point the overall health is in decline, then I repot. But the no growth in the center has seemingly stopped as I use lava rock in the pots. Before it was bark. Bark eventually becomes a no grow area. If you click the picture it makes it larger...

Love your Yellow Bird!
