DECANDLING: JAPANESE BLACK PINE. (June, 2010)
Developed Japanese Black Pines are decandled during this time (see time table below). Depending on each tree’s spring growth, decandling may be done all in one day or spread out over several weeks to balance uneven growth. Remove fertilizer from strong pines after they have been decandled. Note: Decandle strong and well fed trees only.
It has been a cold year. The black pines seem to be growing slower. After decandling, fertilizer should be left on the tree though summer. For trees that are still grow strongly, do not fertilize for 4–6 weeks.
Strong candles, leave longer stubs. Medium size candles, leave a little stub. Small candles, leave no stub.
