Some tropical advise...half research, half experience

So I got a question from one of my readers in Arizona today. She is worried about her Bird of Paradise (BOP). The problem she's facing is that it seems to be healthy, but it will not produce a flower. Sounds odd, but then hey, did y'all read my sob story turned happy ending concerning my irises? I have done a bit of research and combined it with my own knowledge/experience and have a potential solution...we'll see how it works!
The question:

I don't always have the best luck. Can you help me with my tropical bird of paradise? It will not produce a flower.

Here's my response for Mel in Arizona:

Ooh, that's a tough one. So, here's my idea. BOPs like half sun and half shade. They usually have a really spider-like root ball (depends on the species), so be careful when doing this:

The day before you transplant from the pot, water the BOP really well. Soak it. The next day, go to Starbucks, get some grounds for your garden. Carefully uproot your BOP and find a spot with morning sun, afternoon shade. Mix the grounds into your course/rocky soil and securely plant your BOP. Water it really good just after planting and for the next week. After a few days, it'll show shock, but don't worry. Trim back the gross, withering branches/leaves. It'll take a few weeks, but you'll see some new growth hopefully.

Sound like a good plan? You also need to keep in mind that there are many species that need to be in the same spot for two/three years before producing a bloom. Also, just like how most people get depressed and are pretty low functioning when they live alone and have no friends, Birds of Paradise are the same way. They do best in groups because they'll encourage each other to bloom and to spread. I hope this helps! I can't wait to see what you do. I know that you can turn it around.

If anybody else has questions out there, let me know. If I don't know the answer I am happy to research or check with my other, more experienced garden gnomes!
