I have two container bougainvillea in my court yard about 1 year old. I water them once every week.
The flowers are large and there are a lot of them, however, the leaves aren't doing as well. Before I water them, the leaves look dry, curly and limping but stay green, after I thoroughly water them, many of the smaller leaves would turn yellowish overnight and fall.
Am I doing anything wrong? Do I need to change the frequency and amount of watering ? Thanks a lot
