Watercress

About

Watercress (*Nasturtium officinale*) is a fast-growing, aquatic or semi-aquatic perennial herb native to Europe and Asia. It typically grows up to 60 cm (24 inches) in length, with hollow, branching stems that float in water or sprawl over moist ground. The leaves are pinnately compound with oval to egg-shaped leaflets, and it produces small, white flowers in clusters. Known for its peppery, tangy flavor, watercress is one of the oldest known leaf vegetables consumed by humans. 🌞💧 Sun and Water Requirements: Watercress thrives in full sun to partial shade and requires constant moisture, often growing in shallow water or damp soil. It prefers slightly alkaline water conditions and is well-suited to hydroponic cultivation. :contentReference[oaicite:0]{index=0} ✂️🫘 Methods to Propagate: Watercress can be propagated through seeds or cuttings. Seeds should be sown in moist soil or directly in water, while cuttings can root easily when placed in water or wet soil. 🧑‍🌾👩‍🌾 When to Harvest: Harvest young shoots and leaves regularly to encourage bushier growth. Continuous harvesting is possible due to its rapid growth rate.

Practitioner Notes

• Blanch or process within hours if you are freezing—enzymes keep chewing while paperwork waits.
• Label jars with plant part and date the day you seal—future you is not psychic.
• Foot traffic after establishment only—early walks tear stems and invite weeds in the wounds.
• Notebook one weird year—weather anomalies repeat; memory lies, scribbles do not.
