Hardwood cuttings are a reliable way to propagate elderberries, including ‘Adams.’ This method is best done during late fall through early winter when the plant is dormant.
What You’ll Need
Sharp, clean pruning shears
Rooting hormone (optional but recommended)
Well-draining potting mix or sandy soil
Planting containers or a dedicated outdoor bed
Watering can or spray bottle
Plastic bag or mini greenhouse (optional for humidity control)
Step-by-Step Propagation
1. Choose the Right Wood:
Select healthy, mature stems from the current year’s growth. Look for pencil-thick, firm stems with no signs of disease or damage.
2. Cut the Stems:
Use sharp pruning shears to cut 6–10-inch sections of hardwood.
Make the bottom cut just below a node (the bump where leaves attach).
Cut the top end straight across, about 1–2 inches above a node.
3. Prepare the Cuttings:
Remove any remaining leaves, as hardwood cuttings don’t need them.
If using rooting hormone, dip the bottom end of each cutting into the powder or gel.
4. Plant the Cuttings:
Stick the bottom end of the cutting into a pot filled with a well-draining potting mix or directly into an outdoor propagation bed.
Bury the cutting so at least two nodes are below the soil and one or two are above.
Space cuttings 4–6 inches apart if planting in a group.
5. Water Thoroughly:
Water the soil to settle it around the cutting. Keep the soil evenly moist but not soggy throughout the rooting process.
6. Provide the Right Conditions:
Outdoors: Choose a sheltered spot with indirect light or partial shade.
Indoors: Place containers in a cool area with good air circulation. Cover with a plastic bag to maintain humidity if necessary.
7. Wait for Roots to Form:
Hardwood cuttings take longer to root than softwood ones. Be patient! Roots usually develop in 2–3 months, depending on conditions.
8. Transplant Once Established:
Check for root growth by gently tugging on the cutting after 8–12 weeks. Once rooted, transplant the cutting to its permanent location in spring.
Care for Young Plants
Watering: Keep the soil consistently moist but not waterlogged.
