Fertilizer
Fertilizer is an item that can be used on flowers at any growth stage in any flower plot. It can be obtained from composting seeds, flower seeds, troweled flowers, or plucked flowers using the 
Composter that the player unlocks during the "Mulch Be Well" quest.

Other Sources
- Obtained by completing certain
Challenge Courses in 
Merry Meadow a fourth time but can only be obtained once per course (and not from all of the Meadow courses).
Usages
- Increases the chance of propagation (if not in the
Greenhouse) from 1% to 10% per flower.
- Propagation refers to a flower producing a new spawn (as a seed or plant) in a nearby empty plot at reset.
- More new spawns mean more chances for a successful breeding result, but Fertilizer does not increase the chance of getting a rarer result.
- 1% chance per application of giving a regular flower a rare pattern (e.g. the
ombre pattern). - Greenhouse upgrades.
How to Use
To apply Fertilizer to a flower, the player should make sure the flower plot is highlighted as selected, then press the action button for Fertilizer. The button shows how many are left in the player’s inventory. To apply Fertilizer to all flowers in a flower patch, the action button should be held down until the meter above the player’s avatar fills up, then released.
Fertilizer can be used once a day on any flowers except for fully bloomed flowers, newly planted seed packets, and replanted seedlings. A flower can also be fertilized before and after blooming on the same day if the flower blooms from being 
watered.
Fertilizer increases seed propagation (or the chance of a flower producing seeds), which therefore also increases the chance of a flower successfully crossbreeding. Fertilizer may give a flower plant without a pattern the default pattern for that flower's type. Once a flower has a pattern, it can be used to transfer its color across flower types by crossbreeding with other flower types.
Fertilizer has no effect in the Greenhouse except to give flowers their default patterns.
