So you want to grow nasturtiums? Easy. The nasturtium is grown as a natural pest control or for harvesting adorable edible leaves and flowers. They are drought tolerant, so no stress on your watering constraints. Their many different colors will elevate your take out sushi with ease.
Nasturtiums need 6-8 hours of direct sunlight daily. Indoors: Can be grown in pots with bright light or hydroponically using grow lights for 10-12 hours.
Keep soil consistently moist. Indoors, monitor soil moisture frequently; outdoors, water regularly, especially in full sun conditions. Mulching helps retain moisture.
Nasturtiums are a cool weather crop and prefer 55-75°F, ideally 60-65°F. Plant outdoors in early spring (April-May) in NYC zone 7b. Cool temperatures encourage lush foliage and blooms.
Indoors: 8-10" wide, 10" deep, 2 gallons or hydroponically; Outdoors: 10-12" wide, 10-12" deep, 3-5 gallons
Nasturtiums prefer well-draining potting mix with organic compost or cow manure. Indoors, mix potting soil with worm castings, layering 1" worm castings on top.
Apply balanced, water-soluble fertilizer 10-10-10 every 4-6 weeks. Organic options: compost, fish emulsion, bone meal. Consistent fertilization promotes healthy foliage and prolific blooming.
Nasturtiums are ready for harvest 50-70 days after planting, or when the flowers are fully open. The leaves are edible and can be harvested anytime. Nasturtiums typically live for 4 to 6 months.
Pick flowers frequently to encourage more blooms. Regular harvesting helps maintain plant health and ensures a supply of peppery, colorful flowers. The leaves can be grown as microgreens as well.
Pests (Aphids): Wash leaves with soapy water or release green lacewing larvae. Wilting: Water consistently. Yellow Leaves: Moderate watering. Slow Growth: Use balanced fertilizer. Diseases (Powdery Mildew): Improve air circulation.
