Do same techniques apply for candling potted and large bonsai? An article would be helpful. My tree is about 10’ tall.
In general, yes, the same techniques apply. The main difference for large potted or landscape pines is that they are decandled later than trees under 3’ tall. Experimentation is the best guide to get the timing right (it’s hard to say exactly when because the health and size of the tree, as well as the climate all make a difference).
Pulling old needles by hand often makes more sense than using tweezers on large trees, but whatever’s quickest makes the most sense.
