The Bougainvillea Paradox: Neglect It to Make It Bloom
Bougainvillea is arguably the toughest plant on this entire list, and yet one of the most common complaints about it is “it won't flower” — almost always from people who are, ironically, taking excellent care of it. Bougainvillea flowers as a stress response: a root-bound pot, lean soil, and water withheld until the plant is visibly thirsty push it into heavy bloom, while generous watering, rich soil, and a roomy pot keep it lush, green, and stubbornly flowerless. This runs directly against the instinct most gardeners have to give a struggling plant more care, which is precisely the mistake that keeps bougainvillea from blooming on well-tended Indian balconies. If your bougainvillea is thriving but not flowering, the fix isn't more attention — it's less, plus a smaller pot than instinct suggests.
