The toothache plant, Acmella oleracea, is recognized for the tingling and numbing sensation it imparts when its leaves are chewed. This characteristic led to its traditional use in addressing oral discomfort. Incorporating companion planting alongside Acmella oleracea fosters a more resilient and productive garden environment.
Toothache Plant Growing Conditions
The toothache plant thrives in full sun to partial shade, with at least six hours of direct sunlight for robust growth. It prefers well-draining, organic-rich soil for healthy root development. Consistent moisture is beneficial, but avoid waterlogging to prevent root rot. Acmella oleracea prefers warm climates and is sensitive to frost, thriving above 50°F (10°C).
Benefits of Companion Planting with Toothache Plants
Companion planting benefits Acmella oleracea. Some plants deter pests, reducing chemical use and protecting the plant. Others attract beneficial insects (pollinators, pest predators), enhancing biodiversity. They improve soil health by fixing nitrogen, conserving moisture, or suppressing weeds. Strategic placement optimizes garden space and enhances vigor.
Ideal Companion Plants for Toothache Plant
Basil (Ocimum basilicum) is a suitable companion with similar sun and moist soil preferences. Its aroma deters pests (flies, mosquitoes), benefiting Acmella oleracea by reducing pressure. Marigolds (Tagetes species) provide protective benefits. They release root compounds that suppress nematodes, and their scent deters harmful insects.
Nasturtiums (Tropaeolum majus) serve as a trap crop, drawing aphids from desirable plants. Their vibrant flowers attract pollinators, aiding garden health. Borage (Borago officinalis) is a beneficial companion, attracting bees and pollinators, improving fruit set. It enhances pest resistance in neighboring plants.
Low-growing herbs like chamomile (Matricaria chamomilla) act as a living mulch, retaining moisture and suppressing weeds around the toothache plant. Chamomile improves growth and flavor of nearby plants. Cilantro (Coriandrum sativum) attracts beneficial insects (hoverflies, parasitic wasps) preying on garden pests. Their shallow root systems do not extensively compete with the toothache plant for nutrients or water.
Companion Planting Practices and Considerations
Proper spacing ensures air circulation, preventing overcrowding. Allow enough room for each plant to reach mature size without excessive competition for light or nutrients. Consider each species’ mature height and spread, placing taller plants to avoid shading the toothache plant. Grouping plants with similar light and water requirements simplifies maintenance, like watering schedules. Regular observation helps identify issues like pest infestations or nutrient deficiencies, allowing timely adjustments.
