Slightly coarse to fine loamy soils.
Nitrogen-and base-rich soils (Klinka et al., 1995).
soil reaction salinity
Moderately acidic to slightly alkaline (Douglas et al., 2001).
Moist to dry sites (Douglas et al.,1998).
Moderately shade tolerant to shade intolerant (Klinka et al., 1995).
Seral species in moist, open canopied young forests. Climax species on drier sites.

collection and abstraction
Collect seeds when inflorescence and fruits turn brown. Rub fruits over a screen to break them apart and release the seeds (Young, 2001).
Air-dry seeds and store in a refrigerator at 5º C (Young, 2001).
fruit seed dormancy treatment
Soak seeds for 24 hours and cold stratify for six weeks at 5º C. Sow into flats in a sandy/loam soil mix. Germination occurs within 15 days. Prick out germinants and transplant into containers. Seedlings experience die back three to four months after transplanting but re-grow in the spring (Young, 2001).
