Etherbunny, so nice to know you have one! I have a Bauhinia growing in a pot too. Which one do you have.... click the linky below, it'll show you which one I might have. I say "might" because it was a baby when purchased and the only name it had was "Bauhinia Alba" tho had no blooms to prove it.

I live in Southeast Central Florida, and no one should ever mistake me as expert on this subject. But haven't killed it and its not committing any form of harikari yet in the four or five months being with me. Looks healthy enough with no bugs, germs, diseases, so far. I call him the Broohaha tree to get a chuckle. He has no sense of humor.

I don't know how true it is for others but seems to me that repotting the tree makes it pout a little bit. From what you've written, sounds to me like you are doing good things for it; probably might not need any fert till the warmer months come back to NY. Just gonna say what mine has going for it and maybe you'll be able to glean info that can be applied to yours.

It's outside on my back screened-in patio area (south/southwest exposure) and kept double-cached (pot within a pot) so that in case the sun hits it the roots won't get boiled in the soil. The soil used is Bayer Advanced All-in-One potting mix (see BayerAdvanced.com. Btw, I do not work for them nor own any stock or anything like that). The potting soil is amended with lots-n-lots-o-extra grit (fish aquarium small sized pebbles near half-half with the soil) for faster drainage. Sometimes, I insert a wick byway of the inner drain hole to help speed up drainage when I see that it needs that. It goes thru growth spurts just like you described for yours. Only no leaf drop yet. No blooms yet, either. Maybe those will start as it gets a little more cooler here in my neck of the woods. It is almost 8ft, maybe more, I bet more, at this stage with unhappy little branches (my fault--accidentally broke tips of three while potting up to its current size container, which I guess-ta-mate is a 5-gallon capacity, but not sure). To be fully upfront, I'm not at all concerned about the making of blooms. I love his foliage. But if there were blooms some day, I sure hope those will be white.

It gets as much highly (very, very, very) bright indirect light as it can handle which is all day. Except it's been nice and mild the last couple of days so today it got full sun (that is...separated by the screen so I guess that is not really really full sun). For some reason, I bet that's where it wants to be. If so, good job. It did not want full sun as a baby broohaha, lol. One idea that jumps into my head right now.....it seems to love the high humidity surrounding it. Sometimes I placed it on top of rocks in a big sturdy saucer, and filled the saucer of rocks with water; but the bottom of the pot never actually touched the water. I did that during the summer equinox period (super hot super dry weather) and it helped make it happy. I know one thing that guy really hates with a passion is to have its leaves touched by any kind of bug spray---even by wind-drift of that mild soap and water homemade remedy stuff hurts its feelings. If you ever must clean the leaves, for instance to be rid of spidermites, probably the softest cloth ever might be best used.

Feels like I'm just rambling on and on and on. Sorry about that. Etherbunny, tell me about yours so that I can apply what you know to mine and we'll both learn stuff.

Here is a link that might be useful: Bauhinia Alba (or what I like to call, the broohaha tree).
