Light Requirements
Spilanthes radicans Jacq. thrives in full sun to partial shade conditions. It requires at least 6 hours of direct sunlight daily to support proper growth and development. The plant is sensitive to low light intensity, which might lead to stunted growth and yellowing of leaves.
Temperature Requirements
This plant grows best in tropical to subtropical climates. It does well in temperatures ranging between 18°C to 35°C. Temperatures that drop below 10°C might harm the plant, causing frost and freezing damage. Excessive heat over 40°C might lead to dehydration, which could slow down or stunt the plant's growth.
Soil Requirements
Spilanthes radicans Jacq. grows in a range of well-drained soils that are rich in organic matter. The ideal pH range for the soil should be slightly acidic to neutral, between 6.0-7.5. Waterlogged soils can cause yellowing of the leaves or even root rots. Adding compost to the soil can promote vigorous growth and enhance the soil structure, thus contributing to proper drainage.
Cultivation Methods
Spilanthes radicans Jacq., also known as the toothache plant, is a perennial herb that is commonly grown as an ornamental plant. It is easy to grow and requires minimal care. The plant prefers a warm climate and grows well in full sun or partial shade. It can be grown in pots or in the ground.
The seeds of Spilanthes radicans Jacq. can be sown directly in the garden bed or started indoors and transplanted to the garden bed once they have established and the threat of frost has passed. Plant the seeds 1/8 inch deep and maintain consistent moisture until germination.
Watering Needs
Spilanthes radicans Jacq. requires regular watering to thrive. It prefers well-draining soil and will not tolerate waterlogged conditions. Water the plant thoroughly once a week or more often during hot, dry weather. Avoid getting water on the foliage, as this can lead to mildew and other fungal diseases.
Fertilization
Spilanthes radicans Jacq. does not require frequent fertilization but can benefit from a light feeding of an all-purpose fertilizer once a month during the growing season. Avoid over-fertilizing, as this can lead to excessive foliage growth and reduced flowering.
Pruning
Spilanthes radicans Jacq. does not require extensive pruning but can benefit from deadheading to encourage repeat flowering. Deadheading involves removing spent flowers before they have a chance to set seed. This will encourage the plant to produce more flowers and prolong the blooming period.
In addition, Spilanthes radicans Jacq. can be pruned lightly in the spring to remove any dead or damaged growth and to shape the plant. Avoid pruning the plant heavily, as it may reduce flowering.
Propagation of Spilanthes radicans Jacq.
Spilanthes radicans Jacq., also known as the toothache plant, is a herbaceous plant that belongs to the Asteraceae family. It is commonly used in traditional medicine for its analgesic, anesthetic, and anti-inflammatory properties. Propagation of Spilanthes radicans can be done through various methods such as seed propagation, stem cuttings, and root cuttings.
Seed propagation
Spilanthes radicans can be propagated easily by seeds. Collect seeds from a mature plant, and sow them in well-draining soil mix. Sow the seeds just below the surface and cover with a thin layer of soil. Water the soil and keep it moist until the seedlings emerge. It takes around 10-15 days for the seedlings to appear. Once the seedlings have grown to a reasonable size, transplant them into larger containers or into the garden.
Stem cuttings propagation
Propagation by stem cuttings is also efficient in Spilanthes radicans. Take 6-8 inches long of stem cuttings from a healthy mother plant or cutting grown plants. Trim the stem just below a node with a sharp and sterilized tool. Remove the leaves from the bottom half of the stem and dip it in a rooting hormone powder. Then, place the cutting in a well-draining soil mix and keep it moist for several weeks while roots grow. Once the roots have developed, the plant can be transplanted into its final location.
Root cuttings propagation
Propagation using root cuttings is an alternate method of propagating Spilanthes radicans. The root cuttings should be collected from mature and healthy plants. Cut the roots cleanly into several pieces, around 2-3 inches in length, and horizontally to the main stem. Fill the soil mix into a container, place the cuttings on top of the soil, and cover them with a thin layer of soil. Keep the soil moist, and within a couple of weeks, new shoots should appear. Once established, the plants can be transplanted into their desired location.
