Moonlight Nasturtium

Nasturtium

50d to harvest

Moonlight Nasturtium spills over the garden with a cool, luminous presence—delicate blossoms in pale, creamy tones that feel like moonlight caught on the vine. The tender leaves and succulent, peppery seed pods bring a crisp, juicy bite with a gentle heat, ideal for bright garnishes and quick pickling. Grow it for a long season of trailing color and a harvest that’s as lively in flavor as it is in form.

Frequently Asked Questions

What’s the most common disease pest issue for Tropaeolum majus (moonlight nasturtium), and how can I prevent it?

Nasturtiums are frequently affected by aphids and sometimes bacterial leaf spot under warm, humid conditions. Spray plants with a strong jet of water to knock off aphids, then use insecticidal soap if they persist, and remove badly spotted leaves to keep airflow high. Water at the soil line (not on foliage) to reduce disease spread, and avoid crowding so leaves dry quickly after rain or irrigation.

How often should I water Tropaeolum majus during the main growing phase?

During active flowering and growth (roughly weeks after seedlings establish), keep the soil evenly moist but not soggy—water when the top 1 inch of soil feels dry. In hot weather, this may be about 1–2 times per week depending on your soil, while in cooler periods you’ll likely water less. Avoid frequent light watering; nasturtiums do best with deeper soakings followed by drying of the top layer.
