The removed needles. The large group on top are the old needles, starting to yellow. They were loose and easy to pull off, even though many were still a bit green. The bottom group, the smaller, greener group, were the needles pulled off purely for aesthetic reasons, the dangling ones below the foliar pads. These were mostly second year needles…the sophomores…but more on these shortly. The tree without three year old needles. Last year’s and this year’s needles remain on the tree. Unless very full, most pines we use for bonsai will want to retain their second year needles. Some second year needle thinning can bring more budding, which is the tree’s response to this, bringing further ramification. Be sure you have a strong tree before doing that, though, and concentrate on taking off some needles on the strong shoots only. If you decide to skip this, at the very least take off the ones that are easy to pull off. Determining which needles are of which year can be tricky—but looking closely at needle length, needle color, and…
