General Appearance
The jewelweed plant is typically 3-5 feet tall and has succulent stems that are slightly translucent. It has leaves that are oval and toothed, and its flowers can range from yellow to orange, and sometimes red. The plant produces a seed capsule that explosively opens upon touch, scattering seeds as far as 6 feet away.
Uses
The jewelweed plant has a long history of medicinal and practical uses. Native Americans used it to soothe skin irritations, insect bites, and stings. The juice of the plant is a natural remedy for poison ivy and poison oak rashes. The plant can also be used as a temporary treatment for bee stings and hives. It is also used in cosmetics and soaps due to its skin-soothing properties.
The plant is also used as food for wildlife, particularly the seeds, which are eaten by birds. It is also a popular plant for hummingbirds and butterflies due to its nectar-rich flowers.
In addition, the jewelweed plant has been used in dyeing fabrics in shades of yellow and orange. The fibers of the plant can also be used to make cordage, baskets, and other woven objects.
Overall, the jewelweed plant is a versatile and useful plant that has played an important role in the lives of people and wildlife alike.
Light Requirements
Impatiens capensis Meerb. prefers partial shade to full shade. It requires about 3-6 hours of sunlight per day, and direct sunlight for an extended period may lead to stunted growth and wilted leaves. It is best grown under trees or in areas with filtered light, creating a dappled shade.
Temperature Requirements
Ideal temperatures for growing Impatiens capensis Meerb. range from 15 to 29°C (59-84°F). These plants prefer cool conditions and may not thrive in high-temperature regions. With increased temperature, the plants may undergo wilting or lose their flowers. They grow well in regions with high humidity, and the recommended temperature for the germination of seeds is 21°C (70°F).
Soil Requirements
Impatiens capensis Meerb. prefers well-draining soils that are rich in organic matter. It thrives in soils with a pH of 6.0 to 7.0 and requires consistent soil moisture. The plant may suffer if left to dry out, but it should not be overwatered since this may cause root rot. Loamy soils are the most suitable for these plants, offering the optimal balance of moisture retention and soil aeration.
Cultivation of Impatiens capensis Meerb.
Impatiens capensis Meerb. is a wonderful plant to cultivate in the garden. The plant can tolerate different soil types, including loamy, sandy, and clay soils.
This species of Impatiens requires partial shade to full sun to grow. The ideal temperature for optimum growth ranges between 50°F - 85°F. The plant can also tolerate a slightly colder or hotter temperature once established.
To plant the Impatiens capensis Meerb., ensure the soil is moist but not soaking. Plant about 6-8 inches apart and around ¼ inch deep. Cover the seeds lightly with soil, and water using a spray bottle. The seedlings will start to emerge within a few days, and you can thin them out to achieve the desired spacing between the plants.
Watering Needs of Impatiens capensis Meerb.
Impatiens capensis Meerb. needs moderate water to grow. The plant requires consistent watering to keep the soil moist but not waterlogged. The plant can wilt significantly when it lacks enough water. However, ensure you do not overwater the plant, as this can cause root rot and other fungal diseases.
It would be best if you watered the plant during the early morning or late evening to reduce evaporation. Use a watering can or a garden hose to water the plant to avoid spraying the foliage and flowers with water.
Fertilization of Impatiens capensis Meerb.
Impatiens capensis Meerb. requires regular fertilization during the growing season. You can use a slow-release fertilizer that is high in nitrogen to encourage foliage growth and flowering. You can also use liquid fertilizers about once a month during the growing season.
When applying fertilizer, ensure you follow the package instructions to avoid over-fertilization. Too much fertilizer can burn the roots, harm the plant, and compromise its health.
Pruning of Impatiens capensis Meerb.
Impatiens capensis Meerb. requires minimal pruning. However, you can prune the plant to remove dead or faded flowers to stimulate new growth and enhance the appearance of the plant. Deadheading can also help in preventing self-seeding, which can lead to overcrowding and reduce plant performance.
Use a sterilized pruner or a pair of scissors to cut back the spent flowers to a healthy leaf node. You can also trim the plant to manage its height and control its shape. Ensure you prune the plant early in the morning or late in the evening to prevent wilting due to excessive transpiration.
Propagation of Impatiens capensis Meerb.
Impatiens capensis Meerb., also known as jewelweed or touch-me-not, is a flowering plant that belongs to the family Balsaminaceae. This plant is native to North America and is widely cultivated for its showy flowers that come in a range of colors from white to orange. Propagation of Impatiens capensis Meerb. can be easily done through four different methods, namely:
Propagation by seed
One of the easiest and most common methods of propagating Impatiens capensis Meerb. is through seeds. The seeds of this plant can be collected in fall or winter. Sow these seeds in a tray of moist soil and cover them lightly with soil. Place the tray in a warm, bright area. The seeds usually germinate within 10-14 days. Transplant the seedlings into individual pots once they have grown two to three leaves.
Propagation by division
Impatiens capensis Meerb. can also be propagated by dividing the adult plants. This method involves separating one or more sections of the parent plant and replanting them in a new location. To do this, carefully remove the plant from its pot or the ground and gently separate the roots. Replant the sections in individual pots, ensuring that each section has enough roots.
Propagation by cuttings
Another way to propagate Impatiens capensis Meerb. is through cuttings. Take a cutting of the plant from a healthy parent plant, making sure that it has at least two leaves. Dip the cut end of the stem into rooting hormone and plant it in a small pot filled with moist soil. Keep the soil moist and the cutting in a bright, warm area. Roots usually start to grow in four to six weeks
Propagation by layering
Layering is another method of propagating Impatiens capensis Meerb. It is done by bending a healthy stem of the plant down to the soil and keeping it in place with a small weight. Remove the leaves from the area of the stem that is in contact with the soil and cover this section with soil. Keep the soil moist and wait for roots to develop. Once roots have developed, cut the stem from the parent plant and replant it in a new location.
Disease Management
Impatiens capensis Meerb. is susceptible to various diseases that affect its growth and development. Some common diseases include:
- Downy Mildew: This disease is caused by the fungus Plasmopara obducens. Symptoms include yellowing leaves and white spores on the underside of the leaves. To control downy mildew, remove infected plants and improve air circulation around the remaining plants.
- Verticillium Wilt: This fungal disease causes yellowing and wilting of the leaves. Infected plants should be removed as soon as possible to prevent the spread of the disease.
- Rhizoctonia: This fungus causes crown and root rot, which can lead to plant death. To prevent the spread of the disease, remove infected plants and improve soil drainage.
Pest Management
Impatiens capensis Meerb. is also susceptible to various pests that can damage the plant and decrease its productivity. Some common pests include:
- Aphids: These small insects can suck the sap out of the leaves, causing them to wilt and yellow. Pest management for aphids can be done using a strong blast of water to knock them off the plant or by using an insecticidal soap.
- Spider Mites: These tiny pests are often hard to see, but they can cause damage by sucking sap from the plant. Pesticides can be used to control spider mites or by introducing natural predators like ladybugs.
- Thrips: These insects are very small and feed on the leaves, leaving visible stippling. Insecticides can be used to control thrips or by introducing natural predators like mites or minute pirate bugs.
- Slugs and Snails: These pests can cause significant damage to the plant by eating holes in the leaves. Handpicking and using bait can help control slugs and snails.
