  • Don't decandle.
  • Don't pull needles. If you want to reduce needles, you cut them off very short with scissors.
  • Needles only last for two years. Old needles will yellow and turn brown in the fall, and they can be knocked off very easily then.
    They grow extremely slowly. Know that when you prune, that foliage you remove may take a decade to grow back.
  • They are reluctant back budders. Therefore treasure every twig that is close to the trunk.
  • They prefer to be kept dryer than Japanese Black Pine.
  • Expect to wait about 25 to 30 years for the smooth gray bark to get rough.
  • This tree is susceptible to wind damage.

So, knowing all that, what do we do?

Spring Candle Pruning & Shortening



MidSummer is Pine Time

Do keep in mind that the preferred time for major pruning work is mid summer.  In our time zone that is July.



October Care

October is one of the rare time slots where the sap flow on two needle pines is low and the tree can be needle plucked.

You can find an exquisite care guide for Scots Pines in the resources section of bonsainut.com.

My personal keynotes:

  • Spring: bud reducing
  • Mid Summer: Pruning in July
  • Early October: the only window for needle plucking (!)

A picture tells more than 1000 words.  This one shows you when to prune black pine needles and stop fertilizing (May in our northern hemisphere) and then when to start fertilizing again AFTER the new buds have formed and hardened off.

The idea of this article is that it grows, while sharing my research findings and insights in handling Japanese black pines (kuromatsu).
