Plant different colors of the same flower species near one another, water them daily, and leave nearby spaces empty.
Set up a breeding patch
- Start with a few flowers of one species.
- Space them out in a checkerboard pattern so new flowers have room to appear.
- Water daily and check the empty spaces on later days.
What to expect
Seed-grown and transplanted flowers can both be used. Beta reports suggest friends watering your flowers can help, but no bonus percentage is verified.
New colors are chance-based. A checkerboard is a useful starting layout, not a guaranteed or proven optimal formula.
