How to Grow Plants in Ishin

Quick answer

Go to the rooftop school garden, plant seeds at the big communal plant, water the communal soil, then collect the flowers once they are harvestable.

That plant is shared — it is there for everyone to put something in — so you plant directly into the big communal plant. You will know the planting has taken when the thing you planted now needs watering.

Where growing happens

The rooftop school garden is the place to look for. It is on the school roof rather than inside a classroom, and the object that matters there is the big communal plant. Because it belongs to everyone, you walk up to the shared plant and add to it.

That shared nature is worth understanding before you start, because it shapes what the activity is. Gardening here is a small public contribution to a plant everyone uses, and anyone can add to it.

Plant, water, collect

The growing activity runs in three stages, and the guide that describes it gives them in this order:

1. Go to the rooftop school garden. Find the big communal plant that is open for everyone.
2. Plant seeds at the communal plant. Once you have planted, the item you put in now needs water — that is the sign the interaction has begun and the next step is yours.
3. Water the communal soil. Watering is the tending step in the middle of the loop, and it comes after planting rather than before it.
4. Collect the flowers once they are harvestable. Harvestable flowers are the end stage of the activity and the thing you actually take away from the garden.

Reading the stages as a state sequence helps you keep track of where you are. After planting, the plant needs watering. After watering, the next thing you are looking for is flowers in a harvestable state. The description lists only these three stages. It does not say whether watering has to be repeated or how long the flowers take to become harvestable.

What you get: flowers you can carry and give away

Flowers are not scenery that stays fixed to the plant. They behave like items a player holds. In one recorded first-day session, a student moved to pick up a flower and, later in the same session, was holding a flower and handed it to another player.

So the harvest has a social use as well as a practical one. Once you have collected flowers you can carry them around campus and pass one to someone else — useful if you are playing with friends and want to share what the garden produced, or simply want to hand a flower to another student you run into.

Gardening as a way to earn Yen

Rooftop gardening is also listed among the ways students bring in money. It sits alongside science lab potion experiments and the paid job routes — pet cafe shifts, styling hair at the salon, and spraying street graffiti for a city thug NPC.

The description treats gardening as steady income rather than a single payout, which fits the loop: you plant, tend, and come back for flowers, so it is a repeatable background earner next to the clock-in jobs. The paid shifts themselves are covered on the Ishin jobs page.
