Farming Fertilizer III
Farming Fertilizer III is the strongest fertilizer: it raises a bed’s growing skill by 5, despite the III in its name. 8 Peat and a Miracle growth elixir make one, with Anatomy 4, after Fertilizers IV (150 green, 30 blue). You make it at the Formulation Bench, which uses Anatomy mastery, not Farming; the Compost Chemist perk doubles each batch.
The Vineyard Upgrade takes 6, with 6 Advanced Details and 4 Oiled Beams, and raises every vine trellis’s skill from 6 to 11 (see Farming).

Notes
- On a vine trellis before the upgrade it lifts the skill from 6 to 11, so every growing step of Hops (requirement 7) succeeds. Grapes need 12 to 16, so even 11 falls just short of ★1 grapes.
- It stays on the bed. A harvest does not use it up; it only goes when you put a different fertilizer in its slot. Unconfirmed: this follows from the game’s code and has not been checked in play.
- Studying one costs 10 Science and gives 75 green and 25 blue.
