From left to right these are:1. some type of Washingtonia I think. Collected underneath palms in the back of the Hard Rock Hotel in Universal Orlando (if anyone knows what they are I'd love the info, seeds didn't look like Robusta or Filifera);2. from my mother-in-law's CIDP in Cape Coral Fl;3. two pots from underneath her neighbor's Royal; and,4. Christmas from another neighbor. All were germinated this Spring, except the Christmas, which is now 2 yrs. old. Questions: speed of these guys re: growth? Should I repot? And how about fertilizing?
