Fusions need both ingredients on the same fruit (Cleaning Spray can remove a mutation if you mis-stack). Amber ages on the plant; do not harvest if you are waiting for Old/Ancient Amber.
💰 Worked Examples: Old Amber on a Sunflower
Numbers use the site formula Base × (Weight/BaseWeight)² × Growth × (1 + Σmutations − count) and Sunflower's listed base. Plug a live crop into the Grow a Garden calculator for other weights.
🔗 Stacking & Best Combos
Once Old Amber is on a fruit it follows the additive rule with other non-growth mutations: 1 + Σ(multipliers) − count. Gold (×20) or Rainbow (×50) then multiplies that total. Cleaning Spray (Gear Shop, listed on stock) can strip mutations if you need to rebuild a fusion.

❓ FAQ
Does Old Amber use the homepage calculator formula?
Yes. Old Amber is a fruit modifier at ×20, not a crop and not a pet. Plug it into the Grow a Garden calculator with a real kg. This FAQ does not repeat the intro paragraph.
How do you get the Old Amber mutation?
Aging stage of Amber (after 24 hours). Ages into Ancient Amber after 48 more hours.
Does Old Amber stack with Gold or Rainbow?
Yes. Old Amber is not a growth mutation, so Gold (×20) or Rainbow (×50) can multiply it. With other environmental mutations it uses 1 + Σ − count first, then growth.
What crop should I put Old Amber on?
Any crop uses the same multiplier. Worked examples on this page use Sunflower (50,138₡ at 8.55 kg) because that crop is also the Dawnbound reference. Weight² usually moves the number more than swapping a mid-tier crop.
Plug Old Amber into any crop, weight, and mutation stack for the real number.
