Why Choose Nasturtiums for Your Garden?
Nasturtiums (Tropaeolum majus) are prized for several reasons that align perfectly with both beginner and expert gardeners’ needs.
Bright and Long-Lasting Blooms
- Nasturtiums produce vivid flowers in shades of orange, red, yellow, and cream.
- Their blooming period lasts from late spring to early fall, providing continuous color.
Easy to Grow and Maintain

How to Plant Nasturtiums in Your Garden
Selecting the Right Location
Choose a spot with full sun exposure for the best flowering results. Nasturtiums can tolerate partial shade but may produce fewer blooms. Ensure the soil is well-draining to avoid root rot.
Soil Preparation
- Nasturtiums prefer nutrient-poor, slightly acidic to neutral soil (pH 6.0-7.5).
- Avoid rich, fertilized soils to prevent lush foliage at the expense of flowers.
- Loosen the soil to a depth of 6-8 inches and remove weeds.
Sowing Seeds
- Sow nasturtium seeds directly outdoors after the last frost.
- Plant seeds 1/2 inch deep and 10-12 inches apart.
- For an early start, start seeds indoors 4-6 weeks before the last frost date.
Watering and Care
- Water moderately; allow soil to dry between watering sessions.
- Avoid overhead watering to reduce fungal diseases.
- Deadhead spent flowers to encourage continuous blooming.
