It seems like you never got an answer since May!

I have never heard of grafting this tree. Right now when I go outside I see them all around bearing large seed pods. Collect the seed pods that drop from the trees and try growing them from seed.

I recently collected some Pride of Barbados seeds from nearby trees and I've gotten nearly a 90% germination rate!

Growing from seed might take a long time, but it's fun and easy!

This answer is very late but....
My yellow Delonix was purchased as a grafted tree. I wanted to make sure it was yellow so I did not grow it from seed. I do not know how to graft so I can't give any info there, but my tree grew quickly and bloomed in about 3 years.
This is a recent picture.......

It has been a while. However, thanks for the replies. Grafting is important for these trees so you know exactly what you are getting with regards to bloom color like yellow or orange. I am interested in knowing the best time of year to graft and the type of budwood to collect (new growth, 1 yr old, etc), and any other tricks that may help.
