Grown up alstonia scholaris not flowring

[kulkarnivs]

We have alstonia scholaris in our compound (Powai, Mumbai) 

It has grown up appox 50 fts but it is not flowering (Observed last 2/3 years).

Many other trees smaller than this one are flowering.

What could be the reason?

Any remedial action is required?

Kindly provide information

Please check whether it is  receiving proper sunlight.  The tree needs bright sunlight.  The trees grown in shade / semishade areas  may not flower properly during the flowering season. Some times due to lack of potassium in the soil  results in non-flowering  of the tree.
