Seed Information

Seed Treatment Method

Smoke Smoke treatment improves germination in some species. Smokey products, e.g. smokey vermiculite, can be purchased and applied to the sown seed, or sown seeds can be treated directly with smoke from a source such as a drum with a fire and hose.

Seed Treatment Notes

Untreated seed may have low results. Scarification has been recommended to improve germination or smoke may be worth a try.
