Sun Requirements ▾

Full sun is ideal for the most abundant flowering, providing at least 6–8 hours of direct sunlight daily. Nasturtiums tolerate light partial sun, but reduced sunlight may result in fewer blooms and leggier growth.

Watering Instructions ▾

Keep soil evenly moist during germination and early establishment. Once established, nasturtiums tolerate moderate dryness. Avoid overwatering, as consistently saturated soil may lead to root rot and reduced flowering.

Care Tips ▾

Black Velvet Nasturtiums grow best in well-draining soil with moderate to low fertility. Excessively rich soil may encourage foliage growth at the expense of flowers. They prefer stable warm temperatures and average outdoor humidity. Avoid heavy, compacted soil that retains excessive moisture. Direct sow Black Velvet Nasturtium seeds outdoors after the final frost once soil temperatures reach approximately 15–18°C. Seeds germinate best when lightly covered with soil. Plants typically begin flowering in approximately 50–60 days and continue blooming until frost. Regular deadheading encourages extended flower production.
