An early start to the decandling season

May 25, 2018 by Jonas Dupuich

The decandling season is starting earlier than normal for me this year. I’m looking to prepare a few trees for an exhibit in September but the pines in my garden usually grow through October and into November. By decandling early, I can increase the odds that a tree will look good in September at the expense of it looking slightly overgrown by the end of the year. (See “Overview of decandling” for details.)

Here’s one of the trees that needs to be decandled early. It’s growing well following a big bend and repotting in January.

Cascade black pine

In addition to decandling, I want to thin branches that split into three shoots by selecting two to keep and one to cut. Here’s what that process looks like.

Branch with three spring shoots

Although it’s hard to tell from the photo, the shoot on the left is the smallest of the three. The two on the right are about the same size.

Selecting a shoot to remove

Next comes decandling – the removal of the spring growth.

After decandling

Some needle-plucking followed. First the two-year-old needles were removed.

And then a few of last year’s needles were plucked.

After removing a few one-year-old needles

This still left about 12-15 pairs of needles per shoot. While the count is higher than I’d normally leave on a tree like this, the needles are relatively short and the branches aren’t very dense.

Here’s the tree after decandling, cutback and needle-pulling.

The next step – once a few more trees are decandled – is wiring.

    That will look good in September.

    Will you follow up with the wiring stage on this one?

      Hi Rick – if I get around to the wiring, yes, I’ll happily follow-up with this!
