queen palm spacing
hi everyone... i'm planning on planting a couple of queen palms, along my block fence, somewhere in the future. however, i'm a bit confused by how far apart they should be spaced. everything i read says 15' to 25' but when i look at them in local yards there planted about 5' to 10' apart. will there be future problems, when the tree is full grown, if they're planted closer together? i think i know the answer to my next question, but... is it too cool to plant them now? my yards pretty bare still (new construction) and it's easier to plant things while my tortoises are hibernating. thanks, in advance for any advise you have to give.
