In Pikmin coins are the currency used at the in-game store, and they are not easy to come by, especially in the early levels. It is important that you earn coins because they can be used at the in-game shop to purchase useful items that will enable you speed up Seedling growth, buy Nectar to increase your friendship level, or expand your storage capacity. Aside from a few items, nearly everything at the in-game store can be purchased with Coins and this How to get Free Coins will tell you how to get them without spending real money.
It takes between 20 and 40 minutes on average to complete planting 500 flowers in Pikmin Bloom. There is a simple way in which to increase this payout, and that is by increasing your total Pikmin count. The more Pikmin you have collected, the more Coins you are able to earn in a shorter period of time. The Pikmin you should prioritize growing first are Yellow, Blue, and Red as they require the least amount of steps to fully grow, each only needing 1,000 steps in their walking forms. Although other Pikmin such as the Pink and Purple types are nice, they require a lot more steps and take longer to hatch. Keep in mind that growing more Pikmin will come in handy for collecting Pikmin Bloom Expedition rewards.
You will be able to earn coins free passively in Pikmin Bloom by planting flowers with every walk, and the Coins you earn you will be able to spend at the in-game store. It is recommended that you save up for the Bloom Pack, which cost 1,400 Coins. Although this Detector item is the most expensive item at the in-game store it is also the most helpful as it gives you 200 Blue Tulip Petals, 200 Yellow Tulip Petals, 15 Special Slots, 12 Special Nectar, 200 Red Tulip Petals, and 10 scans.
