Propagating Juniperus davurica 'Parsonii' from Cuttings and Layering

How to Propagate Parson's Juniper

Juniperus davurica 'Parsonii' (Parson's juniper) is a low-growing, spreading conifer that roots reliably from cuttings or by layering. Here’s a step-by-step guide for both methods.

Tip Cuttings (Fall–Winter)

1. Take 4–6 inch (10–15 cm) cuttings from ripe (semi-hardwood) wood in late fall or winter.
2. Remove lower foliage, leaving 2–3 sets of needles at the tip.
3. Cut the base at a 45° angle to expose more cambium.
4. Dip the cut end in rooting hormone powder or gel.
5. Insert cuttings into damp sand or perlite in a tray or pot.
6. Cover with a clear plastic dome or bag to maintain high humidity.
7. Place in bright, indirect light; no bottom heat required.
8. Check for roots after 8 weeks by gently tugging; resistance indicates rooting.

Stem Layering (Spring–Summer)

1. Select a young, flexible stem near the ground.
2. Girdle (scrape bark from) a 10-inch (25 cm) section about 10 inches back from the tip.
3. Bend the girdled portion down and bury it in a shallow trench, securing with a U-pin or rock.
4. Cover with soil and keep moist.
5. Roots may take several months to form; leave the layer attached until a strong root system develops.
6. Sever the new plant from the parent, wait a few more weeks, then transplant.

Media and Conditions

• Rooting medium: coarse sand, perlite, or a 1:1 sand–peat mix.
• Humidity: maintain near 100% with a clear cover.
• Light: bright, indirect; avoid direct sun on covered cuttings.
• Temperature: cool to moderate (50–65°F / 10–18°C) is fine; no heat mat needed.

Both methods yield healthy, true-to-type plants. Cuttings are faster for producing multiple plants; layering gives a larger specimen more quickly.
