Open your garden and tap your plant to care for it.
Your plant grows through 5 stages: Seed, Sprout, Young plant, Budding and Full bloom. The care screen shows how much growth each action adds.
When you run out of water or fertiliser, buy more in the garden shop with points. Buying supplies does not grow the plant. You still need to use them.
When a plant reaches full bloom, you can plant a new seed.
