Overview
Coleus malinvaldi (Briq.) Briq., also known as Malinvaud's coleus, is a perennial plant native to Madagascar.
Common Names
The plant is commonly known by its scientific name, Coleus malinvaldi, as well as Malinvaud's coleus.
Appearance
The plant has green leaves with a purple underside, and produces yellow flowers in the summer months. It grows to be about 10-15 cm tall and wide, and has a bushy, mounding habit.
Uses
Coleus malinvaldi is primarily grown as an ornamental plant, due to its attractive foliage and bright yellow flowers. It is also used in traditional medicine for its anti-inflammatory and digestive properties, and is sometimes used in cosmetics for its promising skin-brightening properties.
Light Requirements
Coleus malinvaldi prefers bright but indirect sunlight, although it also thrives in partial shade. Full sun exposure can be detrimental to its growth, and can cause the leaves to scorch or wilt. For optimal growth, the plant should be placed in a location that receives filtered sunlight throughout the day.
Temperature Requirements
The ideal temperature range for Coleus malinvaldi growth is between 18°C and 27°C. Temperatures that exceed 35°C or fall below 10°C can cause severe damage or death to the plant. To prevent damage from the cold, the plant should be protected from frost and kept away from drafty windows. In warmer months, it can be taken outdoors but should be brought back inside when temperatures drop.
Soil Requirements
The plant does best in a soil that is rich and well-draining. It can tolerate a variety of soil types, including loamy, sandy, and clay soils. However, it prefers loamy soil that is slightly acidic with a pH range between 5.5 and 6.8. The soil should be kept moist but not waterlogged, which can cause root rot. Adding organic matter to the soil can improve its texture and nutrient content.
Cultivation Methods:
Coleus malinvaldi (Briq.) Briq. is a tropical plant, so it requires a warm and humid environment to thrive. It is commonly grown as an indoor plant, but you can also plant it outdoors in a shaded area. The plant requires well-draining soil and partial to full shade to prevent leaf scorching. You can propagate them using cuttings or seeds.
Watering Needs:
As a tropical plant, Coleus malinvaldi (Briq.) Briq. requires regular watering to keep the soil evenly moist. Water the plant when the first inch of soil is dry to the touch. Overwatering can lead to root rot, so make sure the soil has proper drainage to prevent waterlogging.
Fertilization:
Coleus malinvaldi (Briq.) Briq. benefits from regular fertilization, especially during the growing season. You can use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium every two weeks. Avoid using too much fertilizer as it can burn the roots and damage the plant.
Pruning:
Pruning Coleus malinvaldi (Briq.) Briq. can help promote bushier growth and prevent legginess. Pinch back the stem tips regularly to encourage side branching. You can also remove any leggy stems to redirect energy to other parts of the plant. Additionally, removing spent blooms can help promote more flower growth.
Propagation of Coleus Malinvaldi
Coleus Malinvaldi, also known as Solenostemon Malinvaldi, is a tropical plant that is prized for its colorful leaves. Propagation of the Coleus Malinvaldi plant can be done through various methods, which include:
Propagation through Stem Cuttings
The most common method of propagating Coleus Malinvaldi is through stem cuttings. Cuttings should be taken from the parent plant in the spring or summer months. Use a sharp, sterilized knife to make a diagonal cut on a healthy stem, making sure the section is at least 6 inches long. Remove the leaves from the lower part of the stem, leaving only the top leaves.
Place the cutting in water or a well-draining potting mix until roots form. Once roots form, the cutting can be transplanted into a larger container or directly into the garden.
Propagation through Division
Coleus Malinvaldi can also be propagated through division. This method is best done in the spring when the plant is actively growing. Carefully dig up the parent plant, being careful not to damage the roots. Divide the plant into smaller sections, making sure each section has roots and foliage. Replant each section into a well-draining potting mix or directly into the ground.
Propagation through Seeds
Coleus Malinvaldi can also be propagated through seeds. Sow the seeds on top of moist soil and cover with a thin layer of soil. Place the container in a warm, brightly lit area, and keep the soil moist. Seeds should germinate within two weeks. Once the seedlings have several sets of leaves, they can be transplanted into larger pots or directly into the garden.
Propagation of Coleus Malinvaldi can be done through various methods and done easily. Choose the method that suits you and the plant’s surroundings best to have it grow and flourish.
Disease and Pest Management for Coleus Malinvaldi (Briq.) Briq.
Coleus Malinvaldi (Briq.) Briq. is a vibrant foliage plant, native to Madagascar and some parts of Africa. It is, however, susceptible to some pests and diseases that may affect its growth and yield. Here are some common pests and diseases that may affect Coleus Malinvaldi, and the ways to manage them:
Pests
Aphids: These are sap-sucking insects that can cause stunted growth and yellowing of leaves. They also leave behind a sticky substance that promotes the growth of black sooty mold. To manage them, use insecticidal soap, neem oil, or horticultural oil.
Spider Mites: These are tiny arachnids that feed on the foliage and cause yellowing of leaves. They can be managed by spraying the plant with water to dislodge them or using insecticidal soap, neem oil, or horticultural oil.
Mealybugs: These are soft, white insects that suck sap and excrete honeydew, which leads to black sooty mold growth. They can be managed by using insecticidal soap, neem oil, or horticultural oil. You can also use a cotton swab dipped in alcohol to remove them individually.
Diseases
Fungal Leaf Spots: These are caused by fungal pathogens that attack the foliage, causing yellowing and browning of leaves. To manage them, remove and discard all heavily infected leaves, improve air circulation, and avoid overhead watering to reduce moisture levels.
Rust: This is characterized by reddish-brown spots on the leaves. It is a fungal disease that spreads through water and air. To control rust, remove and discard all heavily infected leaves, improve air circulation, and avoid overhead watering to reduce moisture levels. You can also use fungicides like copper-based fungicides to manage rust.
Root Rot: This is caused by overwatering and poorly-drained soils, which leads to the death of roots. To manage it, reduce watering frequency and improve drainage. You can also add organic matter to the soil to improve drainage.
Regular monitoring of the plant, proper sanitation, and maintaining appropriate cultural practices, such as watering and fertilization, can help prevent and manage pests and diseases in Coleus Malinvaldi.
