Spring is typically a season for letting bonsai grow freely. For black pines, some of the main tasks include fertilizing and removing young pine cones.

Spring is also a good time for catching up on needle plucking and cutback.
I generally don’t recommend working on pines after the new shoots start elongating as it’s easy to damage tender foliage. The alternative is to wait until decandling time.
For the black pine below, I thought the foliage was fairly dense and that the tree would benefit from additional light in the tree’s interior. Here’s the tree before cutback and needle plucking.

And here’s the tree after this work.

The tree goes right back into the sun and will receive lots of fertilizer between now and decandling at the end of May.
