Actaea dahurica

Germination Tips

*

This species needs special care as described.

8

Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water daily for approximately 7 days. Discard water.

D

Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged.
Special Care: 
scarify with concentrated sulphuric acid for at least 3 hours CAUTION:THIS CAN BE A DANGEROUS PROCEDURE

H

Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged.
Special Care: 
seedlings must be grown at less than 20° and can overwinter at -20°, prick out while small, seed is viable for at least 6m

L

Give sown seeds several weeks @ 20°C to imbibe water (perhaps even germinate!), then expose to fluctuating outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in spring. See https://www.youtube.com/watch?v=SO_KKbGYTEM
