Trachycarpus fortunei – My oldest Palm tree. The house’s gutter is at 13′. This is the most robust, stoutest, of the 5 T.f. that I have with the broadest canopy. It’s male. I’ve just finished cleaning up its rattiest older fronds. I remove 15-20 every year and have been annually while it’s been in its adult active growth phase. It will slow down when it begins to approach its maximum height and maturity.
