Hi.

A neighbor gifted me with an allamanda plant and have been able to keep it really healthy for almost 8 weeks now. However, it has not been blooming at all.

Set-up:

Allamanda is in a container around 11x11x11 container pot. Zone 11, hot and wet. It receives direct afternoon sun, its on a rack in an area of the house thats sufficiently windy.

Care:

I initially used a bloom fertilizer 15-30-15 npk ratio, once a week, 1/2 the dilution strength to full strength of recent application.

I have sparsely pruned off the "woody" (old, brown, non sprouting) side branches in some allamanda, and the tips on the other allamanda to see any difference in type/site of pruning but still nothing.

How can I improve the blooming of my allamanda plants?

Thanks
