Per-container amendments
Scaled linearly to your container size. Apply at transplant or as side-dress per the notes on each line.

- Garden lime Pinch — only if using pure peat (nudges pH up).2 tsp
Growing notes
- Indoor houseplant; bright indirect light. Direct sun scorches leaves.
- Semi-succulent — thick leaves store water; tolerates underwatering far better than overwatering.
- Let the top 1-2" of mix dry between waterings.
- Likes being slightly rootbound; don't overpot. A too-big pot holds too much wet soil and invites rot.
- Drainage hole is mandatory.
- Same recipe family as an aroid mix (pothos, monstera) — slightly less bark.
- NO heavy fertilizer — peperomias are light feeders; excess burns the fine roots and causes leaf drop.
