| Amazingly, the seeds will tolerate near-boiling water. Get some water to the "little bubbles" stage in your microwave, which is in reality slightly below 212F. (if you kept it going for a few more seconds it would be 212F). Careful not to let the water superheat - it might be safest to drop the seeds in with a long spoon. Leave the in the water for about 8 hours after this treatment, then sow. Doing this I got >75% germinating w/Silverhill's Sutherlandia montana seeds. You could also try plain water soaking on a few in case this treatment is too severe for your batch. Sutherlandia montana grows well in zn 8 Seattle - see attached link. -David |
