• Seed starting: 10–20% castings in mix.

• Potting up & indoor plants: 10–25% castings or 1/2" top‑dress monthly.

• Beds & veggies: 1/4–1/2" top‑dress around plants each month or 2–3× per season.

• Lawns: Apply 1/4" top‑dress in spring and fall; water it in.

• Tea vs extract vs top‑dress: top‑dress is simplest; extract for liquid feeding; tea only when sanitized.
