Thank you for the heads up, this might be a problem in the future that I hadn't realized.
The trees are a flowering pear and a flowering cherry, so I'm hoping not too much stuff falls on the deck. We had a crab apple tree before which is dying now, which is why we planted these trees 2 years ago. They're each supposed to grow up to 20 to 25 foot tall, with a 20 foot spread ...
I might have to figure out if I cut them down now and restart, or do it later when it becomes a problem and restart then ... I might just let them grow and figure out how to deal with the problems later ...
