What are Nasturtiums?

• 'Jewel of Africa' - A variety with deep red flowers and dark green leaves.
• 'Red Emperor' - A variety with bright red flowers and edible leaves.

Planting Nasturtiums

Choosing the Right Location

Nasturtiums prefer full sun to partial shade, so choose a location that receives at least 4-6 hours of direct sunlight per day. They also prefer well-drained soil and can tolerate a range of soil types.

Sowing Seeds

Nasturtium seeds can be sown directly in the ground in the spring or fall, or started indoors 4-6 weeks before the last frost date. Sow seeds 1/4 inch deep and 1-2 inches apart. Cover the seeds with a thin layer of soil and keep the soil consistently moist during the germination period.

transplanting

Nasturtiums can be transplanted to larger containers or directly into the ground once the seedlings have 2-3 sets of leaves. Harden off the seedlings by gradually exposing them to outdoor conditions over the course of 7-10 days.

Caring for Nasturtiums

Watering

Nasturtiums require consistent moisture, but make sure not to overwater. The soil should be kept moist but not waterlogged. Reduce watering during the winter months when the plant is dormant.

Fertilization

Nasturtiums are low maintenance fertilization. Feed the plants with a balanced fertilizer once a month during the growing season. You can also use compost tea as a natural fertilizer.

Pest and Disease Management

Nasturtiums are susceptible to pests like aphids, whiteflies, and spider mites. Keep an eye out for these pests and treat the plants with neem oil or insecticidal soap. Regularly inspect the plants for signs of disease like yellowing leaves or powdery mildew. Treat the plants with a fungicide if necessary.
