Growing

Apium graveolens prefers full sun and moist, fertile, well-drained soil rich in organic matter. It requires consistent watering and regular fertilization to maintain succulent leaf stalks. Seeds germinate slowly and seedlings should be started indoors 10-12 weeks before the last frost, then transplanted after frost risk passes. Blanching is optional and can be done by earthing up or tying stalks before harvest. Harvest leaves and stalks before the first significant frost.
