Uses
The Kalaupapa colicroot plant has been traditionally used for medicinal purposes by indigenous Hawaiians for treating stomach pains and indigestion. It was also used as a laxative and to relieve constipation. The roots of this plant are also used for dyeing traditional Hawaiian clothing.
General Appearance
The Kalaupapa colicroot plant is a low-growing herbaceous perennial with clusters of small yellow-green flowers. It has elongated leaves, which are smooth and shiny on top and hairy underneath. The plant has a woody taproot that can reach up to 6 inches in length.
Growth Conditions for Nototrichium viride Hbd. var. kalaupapae St. John
Light: Nototrichium viride Hbd. var. kalaupapae St. John thrives in bright, filtered light. The plant can tolerate full sun, but too much direct sunlight may result in leaf scorching. On the other hand, insufficient light can result in leggy growth. Ideally, placing the plant near a window that receives bright, indirect light would be best.
Temperature: This plant prefers mild to warm temperatures, ranging from 65-75°F (18-24°C). During the winter season, it is important to keep the plant away from cold drafts, open windows, or direct heating sources that are too close as this can cause the plant's leaves to dry out and curl.
Soil: Nototrichium viride Hbd. var. kalaupapae St. John is not particular about the type of soil used, but it prefers a well-draining soil mixture that retains some moisture. A mixture of peat moss, perlite, and compost works well for this plant. It is essential the soil is kept moist but not oversaturated as this can lead to root rot.
Fertilizer: It is recommended to fertilize this plant during the growing season with a balanced, water-soluble fertilizer every two weeks. However, it is important to ensure the soil is not overdosed as this may harm the plant.
Humidity: Nototrichium viride Hbd. var. kalaupapae St. John prefers a moderately humid environment. It can tolerate lower humidity levels, but it will benefit from occasional misting or placing the plant on a tray of pebbles and water.
Cultivation Methods
Nototrichium viride Hbd. var. kalaupapae St. John is native to rocky areas of Hawaii and requires a well-draining soil mixture. It grows best in full sun to partial shade.
Start by selecting a pot that is slightly bigger than the plant's root ball. Fill the pot with a fast-draining cactus or succulent potting mix. Make a small hole in the soil and gently place the plant in it. Cover with soil and press gently around the plant to level it.
Water the plant and let the soil drain. Place the pot in a bright spot with good air circulation.
Watering Needs
Nototrichium viride Hbd. var. kalaupapae St. John needs slightly moist soil to thrive. Allow the soil to dry out between watering. Water the plant once every week or two, depending on the temperature, humidity, and light conditions.
Stick your finger into the soil to check its moisture level before watering. If the soil feels moist, wait for a few days before watering. If the soil is dry, water the plant slowly and thoroughly, making sure the water reaches the roots.
Fertilization
Nototrichium viride Hbd. var. kalaupapae St. John doesn't require frequent fertilization, although it benefits from an occasional nutrient boost during the growing season (spring and summer).
Use a balanced, water-soluble fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Dilute the fertilizer to half the recommended strength and apply it once a month. Water the plant thoroughly before and after fertilizing to prevent fertilizer burn.
Pruning
Nototrichium viride Hbd. var. kalaupapae St. John doesn't require regular pruning, but you can pinch the stem tips to encourage bushier growth.
If the plant becomes leggy or outgrows its pot, you can trim it back to the desired size and shape. Use clean, sharp scissors or pruning shears and make clean cuts at a 45-degree angle to prevent damage to the stem.
Take care not to remove more than one-third of the plant's foliage at once, as this can stress the plant and affect its growth and health.
Propagation Methods of Nototrichium viride Hbd. var. kalaupapae St. John
Nototrichium viride Hbd. var. kalaupapae St. John, commonly known as Green Nototrichium, is a rare endemic plant found in Hawaii. Propagation of this plant can be done through various methods such as seed, division, and cutting.
Seed Propagation
Propagation through seed is the most common method. Collect mature seeds and sow them in a seedbed during spring or summer. Seeds must be covered with fine sand or soil mix, and the container should be kept in a humid area or placed under shade. The ideal germination temperature for this plant ranges from 55 to 65°F.
Division Propagation
Propagation of Nototrichium viride Hbd. var. kalaupapae St. John can also be done through division. Dig up the parent plant early in the spring, and carefully divide the plant into two or three sections. Each section must contain a good root system and several shoots. Plant them in a prepared bed or container with well-draining soil and keep them watered for a few weeks.
Cutting Propagation
Cutting Propagation is a way to propagate this plant during its dormant period. Cut a 4-6 inches long stem from the parent plant, and remove the bottom leaves, leaving only two or three leaves at the top. Dip the cuttings into rooting hormone before planting them in a potting soil mix. Keep them in a partially shaded area and mist them daily until they start developing roots. After that, transplant them to a bigger container or in the garden.
Disease and Pest Management for Nototrichium viride Hbd. var. kalaupapae St. John
Nototrichium viride Hbd. var. kalaupapae St. John is a rare and endangered plant species that originated from Hawaii. As a plant enthusiast, it is important to be aware of the common diseases and pests that might affect the plant and how to manage them effectively.
Common Diseases
Fungal diseases such as powdery mildew, rust, and gray mold are common problems that affect Nototrichium viride Hbd. var. kalaupapae St. John. These diseases are usually caused by wet conditions that encourage the growth and spread of fungi. Powdery mildew appears as a white powdery substance on the plant's leaves, while rust appears as orange pustules on the plant's surface. Gray mold, on the other hand, appears as a grayish or brownish patch on the leaves and stems of the plant.
Pest Infestations
Nototrichium viride Hbd. var. kalaupapae St. John is also prone to infestation by various pests such as mealybugs, spider mites, and scales. These pests cause damage to the plant by feeding on its leaves and sucking out the sap, causing the plant to wilt and die. Mealybugs and scales also leave behind a sticky residue that attracts ants and other insects.
Management of Diseases and Pests
To manage fungal diseases, it is important to avoid overwatering the plant and to ensure that the plant has good air circulation. Removing and destroying infected leaves and stems also helps to prevent the spread of the disease. For severe infections, fungicides may be necessary.
For pest infestations, the use of insecticidal soaps and oils, such as neem oil, can be effective in controlling mealybugs, spider mites, and scales. It is also important to quarantine new plants and inspect them thoroughly for any signs of infestation before introducing them to your garden. Regularly removing dead plant debris and maintaining good hygiene in the garden can also help to prevent pest infestations.
Overall, being vigilant in monitoring Nototrichium viride Hbd. var. kalaupapae St. John for any signs of disease or pest infestation and taking prompt action to manage them can help to ensure the continued health and survival of this rare and endangered plant species.
