- Gardeners starting native and unusual plants from seed
- Worth noticing
- Protocols are reverse-calculated from the gardener’s last frost date and preserve conflicting source instructions.
Field notes
The database addresses a specific translation problem: horticultural instructions such as “70L(90% in 10–14 d)” provide technical shorthand but no calendar date. Deno’s Garden converts those instructions into sequences and works backward from a local last-frost date, including species that need many months or two seasons. The homepage says every published record has been checked by a person and keeps the source wording available for inspection.
