Wow! While the trees are deciding to drop most of their baby plums, the ones they dropped are growing fast! I kind of wonder if the really dry weather has had anything to do with such a high rate of fruit drop, or maybe the trees just aren't mature enough to handle them all? Either way, I decided to give them a supplemental watering this weekend, and if we don't get much of the rain that's forecast for this week, I'll probably be watching again.
Assuming these plums make it all the way, I'll have to remember to mark which branches are which variety - these are 2 in 1 granted trees (and I'm blanking on the varieties right now), but they didn't come labeled with which branch is which type of plum - so no way to know until I have ripe fruit.
