3. Companion Planting
Red nasturtium can serve as an excellent companion plant. Here's how:

- Attract Beneficial Insects: The bright flowers attract pollinators like bees and butterflies, which are crucial for a healthy garden ecosystem.
Growing Red Nasturtium
1. Soil Requirements
Red nasturtiums thrive in well-drained, moderately fertile soil. They prefer slightly acidic to neutral pH levels (6.0 to 7.0). Excessively rich soil may lead to lush foliage but fewer blooms.
2. Light Conditions
These flowers enjoy full sun but can tolerate partial shade. Ideally, they should receive at least 6 hours of sunlight each day to produce abundant blooms.
3. Watering
Nasturtiums prefer consistent moisture but can be prone to root rot if overwatered. It's essential to water deeply but allow the soil to dry slightly between watering sessions.
4. Fertilization
Avoid heavy fertilization. A balanced, slow-release fertilizer can be applied at planting, but these plants tend to perform well in lean soil.
5. Planting and Maintenance
- Seeds: Sow seeds directly into the garden after the last frost date or start them indoors 4-6 weeks before transplanting.
- Spacing: Space plants about 10-12 inches apart to ensure proper air circulation and growth.
6. Pests and Diseases
While relatively pest-resistant, watch for aphids and slugs. Diseases such as powdery mildew can affect them in humid conditions. Proper spacing and good airflow can help prevent these issues.
