Fertilizer
Fertilizer is a substance used to catalyze plant growth. No plant requires fertilizer to grow, but all plants' yields can be improved with fertilizer. Vegetables will grow bigger, flowers will grow more buds, and trees and bushes will grow more branches. Additionally, the first time the player catalyzes growth for a given plant, they will receive an award.
Fertilizer comes in a multitude of colors, with every plant requiring a different kind of fertilizer. Every plant will grow with the use of Special Mix Fertilizer or Cocoadile tears.
In the original game, colored fertilizers can be bought at Costolot's Store, while Ivor Bargain sells his own Special Mix fertilizer. Fertilizer is largely the same in Trouble in Paradise, but since Ivor Bargain's store no longer exists, his Special Mix is now available at Lottie's for a higher price. In Pocket Paradise, fertilizer is not buyable, and therefore must be obtained from Taffly poop.
Using Fertilizer
Fertilizer can be used up to 3 times on any plant, with the exception of weeds. Every plant requires a different color of fertilizer, usually the same color as the plant itself. To use fertilizer, hover over the plant you wish to fertilize and press the A button to sprinkle it over the plant. A sound effect will play when you have successfully fertilized the plant, but another will indicate you got either the type or the timing wrong.
Flowers and vegetables can be fully fertilized from any stage of growth. Flowers will grow more heads, and vegetables will grow larger. The pea is an exception, as it instead grows more copies of the vegetable from one plant, similar to flowers.
Trees and bushes can only be fertilized at specific points of growth. Usually, you will need to watch for buds and fertilize when they appear. Due to this, it’s recommended to keep a close eye on trees and bushes if you want to fully fertilize them. Trees and bushes will grow more branches when fertilized, giving you more spots for fruit to grow.
Obtaining Fertilizer
The most common way to obtain fertilizer is to purchase it from Costolot’s store. It is generally not expensive, but some colors are more expensive than other’s.
In Trouble in Paradise, the Fertilizer Bag was added, allowing you to purchase fertilizer without needing to visit Costolot’s Store.
Special Mix Fertilizer is a unique type of fertilizer sold by Ivor Bargain. Unlike normal fertilizer, it will work for every plant and can be used if you’re uncertain what color a plant needs. In Trouble in Paradise, it is instead sold from Costolot’s Store at a higher price, but is also obtainable from the Fertilizer Bag.
A tamed Cocoadile can be directed to a growing plant. It will cry on it, fertilizing it with Cocoadile Tears. This behaves like Special Mix Fertilizer, but is entirely free.
Taffly Fertilizer
Fertilizer can also be created for free with the use of a Taffly. Feeding a Taffly a fruit will cause the piñata to defecate fertilizer of the respective color. This is the only way to obtain fertilizer as a place-able garden item. Fertilizer obtained in this way can be used on plants similar to fertilizer purchased from the shop.
In Pocket Paradise, Fertilizer is not buyable. The main way of obtaining fertilizer in this game is harvesting Taffly poop, and a tutorial episode is dedicated to this process. Unique to this game is that, once fertilizer has been produced, it can be collected, adding it to the Fertilizer Bag. This saves the fertilizer so that it may be used at a later time.

Cocoadile Tears

Cocoadile tears are free of charge, so long as you have a tamed Cocoadile. Cocoadile tears will effect all plants, so long as the timing is correct. Cocoadile tears are much less efficient and finicky to use than Special Mix Fertilizer, due to the Cocoadile needing to be able to reach the plant.
