Culinary Notes

Chef's Note

Landis Winter watercress brings an aggressive peppery snap with juicy, non-tough leaves, so it doesn’t need cooking to taste “alive.” Use it late—on top of warm food or tossed at the last second—so the heat doesn’t blur that bracing bite.

Best Uses

raw snip-and-sprinkle salads where it stays crisp (no wilting)
ice-cold watercress sauce or blended herb purée for sandwiches and roasts
quick pickling or vinegar-based relishes—keeps its snap and bite

Frequently Asked Questions

What pest or disease commonly affects Nasturtium officinale (watercress), and how can I treat it at home?

Watercress (Nasturtium officinale) is especially prone to downy mildew when leaves stay wet—look for pale/yellow patches on top with a gray-purple fuzzy growth on the underside. Improve airflow and keep foliage drier by watering at the soil line, then remove heavily infected leaves; if it spreads, use an appropriate copper-based fungicide labeled for edible greens and reapply according to label directions.

How often should I water Nasturtium officinale during the main growing phase to keep the soil moisture right?

Keep the root zone consistently moist during active growth—aim for soil that stays evenly damp, not soggy, especially in warm weather. In practice, this often means watering lightly every 1–2 days (more frequently in heat) and checking by feel 1–2 inches down; if it begins to dry at that depth, water immediately.

How do I know when Nasturtium officinale is ready to harvest?

Harvest about 35 days after sowing when plants form a healthy, leafy canopy and new growth is vigorous. Cut the outer stems/leafy tips first, taking only what you can use, and leave the crown to regrow for additional harvests.
