I live in Singapore, where the temperature stays at about 30 to 32 degrees Celsius through the the year. The climate is ultra tropical and there is no seasonal variation in temperature.
Can avocados bloom in such a climate. I know local West Indian varieties do well, however I have a grafted Wurtz that has never fruited. When I bought it other avocados were flowering but mine had no flowers. Was it a fluke graft. The graft Union is clearly visible.
Also the wurtz is in a pot and still very small, should I plant it in the ground and let it grow larger to get fruits. It is temperature or the small size of the tree making the tree not bloom.
Also can other varieties like hass bloom. I heard that avocadoes need cool temperatures to bloom, but shouldn't has and other non West Indian avocado varieties be able to bloom in my climate eventually
How can I also force my West Indian avocado to bloom, it is grafted and about 1.5 meters tall.
You are in a tropical area. Only West Indies race should be worth your while. They don't grow well, I have tried for years and I'm in a subtropical area. The grafted Wurtz you have probably will do worst because is a Guatemalan X Mexican hybrid.
As far as trees growing and blooming, you have to give them time. Small pots are never good for avocados for a long time.
We do have some West Indies X Guatemalan hybrids that should do well like Monroe, Beta and others.
