Propagating Weeping Japanese Maples from Suckers and Cuttings

Two Opportunities from Your Sister's Tree

The "sucker" at the base is likely rootstock growth (different leaf type). The weeping laceleaf is grafted on top. You want the grafted variety, not the rootstock.

Option 1: Cuttings from the Weeping Top (Correct Method)

1. Take 6+ inch tender shoots from weeping branches
2. Avoid woody growth
3. Strip lower leaves
4. Dip in rooting compound
5. Stick 1 inch in wet potting mix
6. Cover with clear plastic
7. Indirect light (east window/fluorescent)
8. Check rooting at 2 weeks (gentle tug test)
9. Remove plastic when rooted; keep moist

Option 2: The Sucker (Rootstock - Different Plant)

• Different leaf type = different genetics
• Will grow into upright green maple, not weeping laceleaf
• Can be grown but won't match desired variety

Puget Sound Climate Advantage

Cool, humid summers ideal for rooting. Take cuttings June-August. Overwinter rooted cuttings in cold frame or unheated garage.

Grafting Alternative

For 100% true-to-type, learn side-veneer grafting onto seedling rootstock in late winter. Scion from weeping top; rootstock = Acer palmatum seedling.
