Pomegranite dropping blossoms/fruit
I have a new 15 gal Wonderful Pomegranite tree planted last fall. It leafed out this spring and is producing many blossoms and young fruit but they are ALL falling off. The largest "fruit" was about 1" diameter before falling off. I currently water it for 40 minutes, every 9 days and it has good drainage. The leaves appear very healthy (green and shiny) and lots of blossoms blooming.
Is it normal for all/most of the blossoms/fruit to fall off? Is the tree too small to produce significant fruit crop? Might I be watering too much or too little?
Any help or recommendations would be appreciated. Thanks!
