Question
I recently had 2 raywood ash trees removed due to root system. I also have a queen anne palm that is possibly raising pool decking from the roots. The ash trees were about 10-15 feet away from pool. Do you think the ash roots are raising the deck or the palm?

Answer
The ash would be the tree that could cause problems with the invasive roots. The palm does not have invasive roots and would not be causing the lifting of the pool deck.  The Queen palm's root base is known as a noninvasive type so the tree is popular to plant around swimming pools and walkways. As the tree grows, the roots spread wider but only usually as wide as the fronds, which can spread 12 feet. The roots are from 1 to 4 feet deep.
