Fertilizer

Fertilizer is bought from Costolot's shop or produced when a Taffly eats fruit; it comes in a variety of colors. It is used to give plants a boost. Giving plants the appropriate color of fertilizer will make them grow faster and produce larger and more valuable fruit.

For most plants, you can use three applications of fertilizer immediately after planting them for maximum effect. Some plants however, such as the Apple Tree require a different strategy to fully boost growth.

Fertilizing an apple tree or an Oak Tree is trickier than other vegetables or flowers. Instead of fully fertilizing 3 times right after planting, you have to wait until certain stages in the tree's growth to fully fertilize it. Immediately after planting you can fertilize it once with its fertilizer. Then you must wait until the tree has grown. You can tell when the tree is ready for more fertilizer when it shakes and leaves fall from the branches. Wait again for it to shake and then you can perform the last fertilization. Make sure it's watered, wait for it to grow, and you should have a fully branched tree that has more branches and will produce more fruit!

If you feed fruit (or vegetables?) to a taffly, it will create fertilizer of the same color that the plant required e.g. Apples will turn into red fertilizer and Carrots into yellow and so on.
