I have three magnolia trees, two of which are blooming again. Is this common? I don't know what type they are. One has all white blooms and the other pink and white. These pictures are from April 1st, 2007. They bloomed wonderfully at the end of March, early April this year (2007) and are now just starting to bloom again (July 20th started). They didn't bloom twice last year. This is only our second year in this home so we don't have a long history with this property. Are we doing something right...or is it just dumb luck?
