Bougainvillea summered outside, wintered inside for 2 years. Now bare of leaves/flowers. Owner wants to cut back to 4–6 inches on main branches. Expert Darlene: soil looks like garden soil, not potting mix. Needs 1:1:1 potting soil/perlite/sand. Appears dry. Prune to 2 leaves per branch, give half-strength bloom fertilizer, place in very sunny spot (4+ hrs sun) or under fluorescents 14 hrs/day. Will sprout in 4–6 weeks.

Follow-up: owner repotted with new soil, untangled branches, new growth at tips. Darlene: prune at blue tags (leave 2 leaves), sun and fertilizer will cause back-budding. Rooting cuttings is 50/50 under lights/misting. Gradual pruning + fertilizing = bushy by spring. Not toxic to kittens.
