JBP Cuttings Propagation

This is tentatively a “TIL” as I have not been successful in the past. But Boon FB group has shared success and so I’m inspired to try again.

One thing I am appreciating now is that “cuttings do not get moisture from the lack of roots, but a moist environment is required for growth.” With recent success with placing collected trees in condensation bags—I will try this with cuttings.

Here are some tips for propagating Japanese Black Pine trees using softwood cuttings: (suggested candles)

Select a healthy branch

Choose a branch that is disease-free and has vibrant growth.

Take the cutting

Use sharp, clean pruning shears to make a 4–6 inch cut from the branch. The cutting should have several nodes, which will become root sites.

Prepare the cutting

Remove all but the top few leaves to reduce moisture loss. Dip the cut end in rooting hormone to encourage root growth.

Plant the cutting

Use a well-draining mix of peat and perlite. Gently work the cutting into the soil and stabilize it with a piece of wire. Make sure the cutting doesn't move, as this could break off any new roots.

Care for the cutting

Maintain consistent moisture without waterlogging. Handle new roots with care, as they are fragile.

When to take cuttings

The ideal time to take cuttings is from early to mid-autumn, or in midwinter.
