Light: Commelina subulata Roth thrives in bright to partial shade. Direct sunlight can cause the leaves to wither and yellow. Keep in mind that insufficient light can also affect the plant's growth and delay its flowering.
Temperature: This plant prefers warm temperatures ranging from 18°C to 30°C. Temperatures below 12°C can damage the plant or even cause it to die. It cannot tolerate frost. When grown in tropical areas, it can grow throughout the year.
Soil Requirements: Commelina subulata Roth prefers a well-draining soil mixture that is rich in organic matter. The soil's pH should range from neutral to slightly acidic (6.0 to 7.5). The plant can grow in a wide range of soil types, including clay, sand, and loam. However, it cannot survive in waterlogged soils.
It's recommended to add slow-release fertilizers to the soil to enhance plant growth and blossoming, especially during the growing phase.
Cultivation Methods
Commelina subulata Roth, commonly known as the Stringy Stonecrop, is an easy-to-grow plant that is typically propagated by seeds or stem cuttings. The plant thrives in well-draining and slightly acidic soil. Ensure that the planting medium is rich in organic matter and compost. Place it in partial to full sun, but protect it from direct sunlight exposure during the hottest parts of the day.
Watering Needs
The Stringy Stonecrop requires moderate watering. Water the plant weekly or whenever the soil dries out. Over-watering should be avoided as it can cause root rot. The plant can tolerate slight drought but it is essential to avoid waterlogging. Water the plant early in the morning to allow the soil to dry out during the day.
Fertilization
A well-manured soil adds essential nutrients to the plant's growth. When planting the Stringy Stonecrop, add compost or well-rotted manure into the soil. Top dress the plant with a balanced fertilizer every three months while watering. Avoid over-fertilizing as this could damage the plant roots.
Pruning
The Stringy Stonecrop is a low-growing plant and requires minimal maintenance pruning. However, removing dead or yellow leaves helps to promote the growth of new leaves. To encourage the plant to become bushier, pinch out the tips of the stems just above the leaf nodes. This will also encourage more substantial flower production.
Propagation of Commelina subulata Roth
Commelina subulata Roth, also known as ‘stringy wandering Jew’, is a beautiful trailing houseplant that is native to South America. This plant is easy to propagate and can be easily grown by division and stem cuttings.
Propagation by Division
The division is the easiest and most common method of propagating Commelina subulata Roth. It is best to divide the plant during the spring or summer. First, carefully remove the plant from its pot and gently separate the root system into two or more portions. Ensure that each portion has enough foliage and root system. Pot each portion into a separate pot with well-draining soil and water adequately. Place the newly potted plants in a well-lit area but away from direct sunlight for a few days.
Propagation by Stem Cuttings
Another way to propagate Commelina subulata Roth is by stem cuttings. First, take a healthy cutting from the parent plant by making a clean cut below the node. Ensure that the cutting is at least 4-6 inches long and has a few leaves on top. Dip the cut end in rooting hormone powder and place it in a pot filled with well-draining soil. Water the cutting adequately and cover the pot with a plastic bag to retain moisture. Place the pot in a bright, indirect light location, maintaining the moisture level. Roots will emerge in a few weeks, and the cutting will be ready to be transplanted into a larger pot.
In conclusion, division and stem cuttings are easy and reliable methods to propagate Commelina subulata Roth. They both provide the opportunity to expand the plant collection or share this beautiful trailing plant with friends and family.

Common Diseases
Leaf Spot: One of the most common diseases affecting Commelina subulata Roth is leaf spot. This disease appears as small, circular, brown spots on the leaves. It is usually caused by bacteria or fungi. To manage this disease, remove any affected leaves immediately and destroy them. Avoid overhead watering and ensure that the plant has good air circulation.
Root Rot: Root rot is a fungal disease that affects the roots of the plant. This disease can be caused by overwatering or poor drainage. To manage root rot, remove any affected roots and repot the plant in fresh, well-draining soil. Ensure that the plant is not overwatered.
Powdery Mildew: Powdery mildew appears as a white, powdery substance on the leaves of the plant. It is usually caused by poor air circulation and high humidity. To manage powdery mildew, increase air circulation and reduce humidity around the plant. Apply a fungicide if necessary.
Common Pests
Aphids: Aphids are small, sap-sucking insects that can cause damage to the plant. They are usually found on the undersides of leaves and can cause stunted growth and yellowing of leaves. To manage aphids, spray the plant with a strong stream of water to dislodge them or apply insecticidal soap.
Spider mites: Spider mites are tiny pests that are difficult to see with the naked eye. They can cause damage to the leaves by sucking the sap from them. Infested leaves appear yellow or brown and have a speckled appearance. To manage spider mites, spray the plant with a strong stream of water or apply insecticidal soap. Ensure that the plant has good air circulation.
Mealybugs: Mealybugs are small, white, cottony insects that can be found on the leaves and stems of the plant. They can cause stunted growth and yellowing of leaves. To manage mealybugs, remove any affected leaves and apply insecticidal soap.
