I'm not bougie expert but this looks a lot like a Pink Pearl Bougainvillea that has been indoors for a long time. (but since you live in CA that would seem weird) The reason I say that is because it looks a lot like mine (Boug Galabra) does when I can finally put it out after spending all winter and part of spring in the house. The leaves dry up and burn off and are soon replaced with new foliage.
However i get the feeling that none of that actually applies in this case. (not sure why i just do)
Thanks a lot Ang3fir3 for your information. However, it has never been indoor. My friend dug this tree (its base is 5" diameter) in 12/08 and gave it to me that time. I barerooted it and put it in pure turface. I also made 3 cutting from its branches, so far 2 alive. I let it stay in full sun since 3/09. It started bracting 2 weeks ago. In recent 5 days, temp. in my area went up in the range 105 -110 F, so, that's why its leaves is drooping (sign of dehydration
) even though I watered it twice a day. Probably turface didn't keep water enough for bougie in hot summer. However, if you want to have your bougainvillea produce more bracts, besides sunlight, high iron food and rootbound, it needs dehydration some time (you may already know that the stress on bougie makes it form bracting). I also have 2 other types of bougie( I don't know their name, so I will ask you later
) which I also place them in pure turface, and they have been producing lot of bracts.
For this tree, I may add pine bark to soil content in the next transplant to reduce water bill
, espcially CA need water at this time. Bonhe
