Q.I want a shade tree — can I plant one in a very limited space? I am thinking of a Christmas Palm. I also need to know the plant
zone for Naples Fl.? Twenty feet tall is about the average or mature height I’m looking for. Do their roots tend to spread out greatly, or do they tend to become compacted?

The Christmas Palm (or Manila palm) may be a good choice for your limited space. The root systems are not considered invasive and will predominate in the area where they get water and nutrients and where there is containment with a wall or planter. Naples, Fla., is in zone 10a.
