Fertilizer speeds up the process of giving birth in the garden. In the store, five uses of fertilizer costs 120 beads. To give the seed fertilizer, you go to your garden. Next to your seeds, there is a button that says "Give Fertilizer." You click that button and your seed gets fertilized. Also, if you take care of your babies, all of your seeds will automatically grow the next day. If you take care of your babies but don't give fertilizer, the seed grows by 3%. If you only give fertilizer, the seed grows 4%. With both fertilizer and good care of your babies, the seed will grow 5%.
