I have a pixie bougainvillea that has been indoors all winter but receiving natural light from south facing windows. I just moved it outside 2 days ago. Some of the leaves are now turning whitish. Is this anything to be concerned about? Should I defoliate in order to coax it into pushing out new leaves?

They need the same progression coming outdoors reversed in the autumn going indoors: shade, bright shade, dappled sun, part (or east) sun, full sun. Then in autumn: full sun, part sun, dappled shade, bright shade, full shade. Each step needs about 5 to 7 days for the plant to acclimate its photo receptors to slightly changed intensities.

So what happens when one plunges bougies from full sun to full shade
They will drop their leaves. Mine do that every time I bring them in for the winter because I don't wean then off the direct light. Not a big concern for me though they always push out new leaves after dropping them. If you don't want to deal with a bare tree for a month or two inside then it's best to wean them.
