Tree Fertilizer is the only fertiliser made for trees instead of crops. Sprinkled on a freshly planted tree seed or a young sapling, it pushes the tree through its growth stages far faster than normal. It also keeps the tree growing through Winter, when unfertilised trees stand still. It works on wild trees such as Maple, Oak and Pine, and more slowly on Mahogany and Mystic Trees, but never on fruit trees or Tea Bushes. Cheap to make from Fiber and Stone, it is the quickest way to turn a handful of seeds into a grove ready for Tappers.
The in-game description reads: Sprinkle on a wild tree to ensure rapid growth, even in winter. Doesn't work on fruit trees.
Recipe
The recipe unlocks at Foraging level 7. Each craft needs only Fiber and Stone, two of the most common materials on any farm. Cutting weeds and grass gives Fiber, and breaking rocks gives Stone.
A Bone Mill is the other way to get it. Feeding bones into the mill gives a random fertiliser, and Tree Fertilizer is one of the possible results.
These are the ingredients one batch needs.

Use
Tree Fertilizer has to go onto a tree that is already planted. It cannot be spread on bare soil ahead of time. Holding it and using it on a seed or a sapling applies it.
A fertilised wild tree usually grows by one full stage every night. Maple, Oak and Pine Trees planted from seed reach full size in about five days this way, ready for a Tapper or the Axe. Mahogany and Mystic Trees speed up too, but they still have only a chance of growing each night, so they take longer.
Winter is where the fertiliser really shines. Unfertilised trees do not grow at all during Winter. Fertilised ones keep growing as if it were any other season, so a winter planting can be ready by Spring.

Notes
Fast-growing trees open up several plans. A grove of Oak Trees grown in a week feeds Tappers with Oak Resin for Kegs. A row of Pine Trees supplies Pine Tar for Speed-Gro and Looms. Mahogany Trees can be chopped for Hardwood, so fertilising Mahogany seeds is a way to grow that scarce material at home. A tapped Mahogany Tree drips Sap every night. Mystic Trees, once grown, give the Mystic Syrup that the Treasure Totem needs. Trees also give a steady supply of Wood and Sap for crafting all year, Winter included.
Fruit trees follow their own rules. They grow in any season without help, so they never need Tree Fertilizer.
