Someone mentioned this here but I can't find it. I just saw a 2nd honey murcott split wide open from the bottom. The first was few months ago & was 1/2 inch or so . This one was over a inch... I ate it - was good even though not mature! What causes this? I think I remember it was a watering issue (?) The good news is, the biggest - over 2 inches, is turning color & lots of blossoms are opening! Thanks for any advice.
