The tomato life cycle is divided into four stages: vegetative, first flowering cluster and first fruit-set, fruit filling (fruiting) + new flowering clusters and last ripening and harvest.
Each having its own set of growth habits and development requirements. During the vegetative stage, stems and leaves develop, and they require nitrogen to do so. Flowers and fruits necessitate lower nitrogen levels and greater potassium and phosphorus levels for optimal fruit production, development, and growth.
Tomatoes are annual plants that grow from a germinating seed to a plant with fruit bearing seed in a single season.
