Nasturtium

50d to harvest

A riot of warm, sunlit color—Phoenix nasturtium blooms with velvety, painterly petals that glow like ember-orange over lush, trailing foliage. The leaves and blossoms offer a peppery, lively bite with a crisp, tender snap, perfect for bright garnishes and vibrant flavor-forward salads, while the seeds mature for bold, tangy pickling. Grow Phoenix for a fast, showy 50-day burst of edible beauty that spills gracefully from containers or garden edges.

Frequently Asked Questions

What pest or disease problems commonly affect Tropaeolum majus (nasturtium), and how can I control them?

Watch for aphids and caterpillars, which cluster on tender new growth; rinse aphids off with a strong jet of water and remove heavily infested shoots. If you see powdery white coating, treat early with a baking-soda spray (1 tablespoon baking soda per gallon of water) applied to affected leaves in the morning, and improve airflow by spacing plants and avoiding overhead watering.

How often should I water Tropaeolum majus during the main growing phase to keep it flowering?

During active growth, water when the top 1 inch of soil feels dry, then water deeply so moisture reaches the root zone. Keep the soil evenly moist but not soggy—too-wet conditions reduce flowering and invite leaf disease; in full sun heat, this often means watering about 1–2 times per week depending on your soil.

How do I know when Tropaeolum majus is ready to harvest?

Harvest seed pods and leaves once plants are well established and still before pods fully harden—at roughly 45–55 days from sowing, pods should be green and plump with seeds inside. For edible flowers, pick blooms as soon as petals open and continue harvesting regularly to encourage more flowering until cool weather slows growth.
