Garden Notes
Scarification

Horticulture expert Dr. Lelia Kelly defines the gardening term scarification. Scarification is the process of weakening, opening, or abrading a hard seed coat to allow seed germination. Some seeds will not germinate until the seed coat degrades. The usual method of scarification for the home gardener is mechanical: scraping the seed with a file or knife. Commercially, scarification is also done using acids.
