I have cut some trees in my garden. If I don't remove the trunks and the roots, which are almost one meter apart in the ground, can plants like climbing jasmine or bougainvillea grow in the soil between them?

I planted a dozen 5-gallon bougie la jollas on the slope behind my house in southern California 4 months ago. They were coming in beautifully until recently when the flowers started to turn light pink, then pale, before turning light brown and falling off. Too much water? Not enough? Please help.
Bougainvillea plants are spectacular while in bloom. It just doesn't last long enough. Each variety has somewhat of a different length in blooming time. As each bloom scape matures, the intense color dulls, fades, browns then falls.
This plant is 3 years old, in a well drained spot with lots of sun but grows little and rarely has a bloom.

It has been fine but just started to drop leaves and look sorry for itself.
I would look to a watering issue. Make sure that it is getting enough water. If it is in the ground, make sure the water is getting deep enough. If it is in a container, make sure you are watering daily.
It may also be either a fungus or a pest. As a precaution, treat the plant with neem oil to take care of both these issues.
I bought a bougainvillea last year and had it in a large pot, and it did very nicely. This year I would like to plant it in the ground, so it has room to grow and climb. I'm told that I should prune it to get more blooms and growth. Is this true and, if so, what should I prune, how much and is now a good time?
