Q.mock orange blooming
How old does a mock orange need to be before it starts to bloom? We planted a mock orange bush 3 years ago We didn’t expect it to bloom for the first year or two. This is its third spring. How long will it take to bloom?

It can take a mock orange 3-5 years before it reaches a mature bloom state. For more information on mock orange, please visit the following link:
