Its trailing or climbing habit also adds visual interest, whether cascading from containers or scrambling along fences. Nasturtiums are truly a gift that keeps on giving, offering beauty, flavor, and ecological benefits all in one.
The Story
Nasturtium Tropaeolum originates from the Andes Mountains of South America, particularly in Peru and Bolivia. The Incas used it for medicinal and culinary purposes. European explorers brought it back to Europe in the 16th century, where it quickly gained popularity as an ornamental and edible plant.
The name "Nasturtium" comes from the Latin word for "nose-twister," referring to the plant's peppery aroma and taste. The plant's bright colors and unique flavor have made it a staple in gardens and kitchens worldwide. It has become naturalized in many temperate regions, often seen growing wild along roadsides and in fields. In some cultures, it symbolizes victory and patriotism.
Complete Care Guide
Nasturtium Tropaeolum thrives in well-draining soil and prefers full sun to partial shade. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilize sparingly, as excessive fertilization can promote leaf growth at the expense of flowers.
Pinch back the tips of the stems to encourage bushier growth and more blooms. Deadhead spent flowers to prolong the blooming period. Protect from frost, as Nasturtiums are sensitive to cold temperatures. Provide support for climbing varieties. Monitor for pests like aphids and treat as needed. Ensure good air circulation to prevent fungal diseases.
Light Requirements
Nasturtium Tropaeolum thrives in full sun, which translates to at least 6 hours of direct sunlight per day. In hotter climates, provide some afternoon shade to prevent scorching of the leaves and flowers. Insufficient light can lead to leggy growth and reduced blooming.
If growing indoors, place your Nasturtium near a sunny window, ideally facing south or west. Rotate the plant regularly to ensure even light exposure on all sides. You can supplement natural light with grow lights, especially during the shorter days of winter. A good indication of insufficient light is elongated stems and fewer flowers.
Seasonal Care
Spring
In spring, sow seeds directly into the garden or transplant seedlings. Provide regular watering and fertilize lightly. Monitor for pests and diseases.
Summer
During summer, ensure adequate watering, especially during hot weather. Deadhead spent flowers regularly to encourage more blooms. Provide afternoon shade in hotter climates.
Fall
In fall, collect seeds for planting the following year. Cut back the plant to encourage new growth. Reduce watering and fertilization.
Winter
Nasturtiums are sensitive to frost and are typically grown as annuals. In mild climates, they may survive the winter with protection. Reduce watering significantly during winter.
The Life of Your Nasturtium Tropaeolum
Seedling / Juvenile
Start seeds indoors 4-6 weeks before the last expected frost. Use a well-draining seed starting mix. Keep the soil consistently moist but not waterlogged. Provide bright, indirect light. Harden off seedlings before transplanting outdoors.
Adolescent
As the plant develops, provide support for climbing varieties. Pinch back stem tips to encourage branching. Monitor for pests and diseases. Water regularly, allowing the soil to dry slightly between waterings.
Mature
During the blooming period, deadhead spent flowers regularly to encourage more blooms. Fertilize lightly with a balanced fertilizer. Ensure adequate sunlight and water. Monitor for signs of stress, such as yellowing leaves.
Established
After the blooming period, you can allow the plant to self-seed or collect seeds for planting the following year. Cut back the plant to encourage new growth. Reduce watering and fertilization.
Propagation Guide
Nasturtium Tropaeolum is most commonly propagated by seed. Sow seeds directly into the garden in spring after the last frost or start them indoors 4-6 weeks prior. Soak the seeds in water overnight before planting to improve germination.
Nasturtiums can also be propagated by stem cuttings, although this method is less common. Take 4-6 inch cuttings from healthy stems and remove the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting should occur within a few weeks. Division and keiki propagation are not applicable to Nasturtium.
Expert Knowledge
To maximize blooms, avoid over-fertilizing with nitrogen-rich fertilizers, as this will promote leaf growth at the expense of flowers. Pinching back stem tips regularly will encourage bushier growth and more blooms. Nasturtiums are excellent companion plants for many vegetables, as they attract beneficial insects and deter pests. The peppery flavor of the leaves and flowers adds a unique touch to salads and other culinary creations.
Troubleshooting
Yellow leaves
Yellow leaves can indicate overwatering, nutrient deficiency, or pest infestation. Check the soil moisture and adjust watering accordingly. Fertilize with a balanced fertilizer. Inspect for pests and treat as needed.
Brown leaf edges
Brown edges on leaves can be caused by underwatering, dry air, or fertilizer burn. Adjust watering frequency and increase humidity. Avoid over-fertilizing.
Drooping leaves
Drooping can be a sign of underwatering or root rot. Check the soil moisture and adjust watering accordingly. Ensure the soil is well-draining.
Root rot
Root rot is caused by overwatering and poor drainage. Improve drainage by adding perlite or sand to the soil. Allow the soil to dry out completely between waterings.
Pests
Aphids, spider mites, and whiteflies can infest Nasturtiums. Treat with insecticidal soap or neem oil. Ensure good air circulation to prevent infestations.
