Light Requirements
Plectranthus phryxotrichus Briq. requires bright, indirect sunlight to thrive for extended periods. If the plant is exposed to direct sunlight, the leaves can burn, and it can stunt the growth. Therefore, it is recommended that the plant is repositioned frequently so that it can receive enough light from all angles. If placed on a windowsill, the plant should be protected with a sheer curtain or a shade cloth to filter the sunlight.
Temperature Requirements
This plant requires warm temperatures to survive and thrive. Optimum temperatures for the plant range between 65 and 80°F (18-27°C). The Plectranthus phryxotrichus Briq. should not be subjected to temperatures below 50°F (10°C). Low temperatures can cause certain parts of the plant to die or stunt growth. The plant should, therefore, be kept away from cold drafts, particularly during winter.
Soil Requirements
The soil used for Plectranthus phryxotrichus Briq. should have good drainage properties. The plant prefers slightly acidic soil with a pH of 6.0 to 7.5. A mixture of peat moss, garden soil, perlite, or vermiculite can be used to prepare the soil. The soil in which the plant grows should be kept consistently moist. However, it should not be waterlogged as this may cause root rot and other fungal diseases. It is advisable to allow the top 1 inch (2.5 cm) of soil to dry out before watering the plant thoroughly.
Cultivation
Plectranthus phryxotrichus Briq. is a hardy and easy-to-grow plant that thrives well in both indoor and outdoor environments. It is known to prefer a warm and humid climate with temperatures ranging from 60°F to 75°F. If you live in an area with a cold climate, consider planting it in a greenhouse or indoors.
Ensure to plant it in well-draining soil with a pH level of 6.0 to 7.5, enriched with organic matter. Using a soil mixture of peat moss, perlite, and vermiculite will ensure adequate drainage for its roots. It should be positioned in a spot that receives partial to full sunlight, and the pot or container should be adequately sized to accommodate its towering growth.
Watering needs
Plectranthus phryxotrichus Briq. grows well in moist soil that is well-drained. Therefore, it is crucial to allow the soil to dry before watering again. Over-watering can lead to root rot and damage the plant's growth. It is best to check the soil's level of moisture with your fingers before watering to avoid dampening the soil, which can attract pests and cause bacterial infections.
Drought conditions can lead to stunted growth and discoloration of leaves. If you reside in areas that experience low humidity, consider misting the plant frequently, or use a humidifier to maintain the moisture level around it.
Fertilization
It is essential to fertilize the Plectranthus phryxotrichus Briq. plant regularly to maintain its vibrant color and robust growth. Apply a balanced liquid fertilizer every month during the growing season. Alternatively, you can use a slow-release fertilizer twice a year- during spring and mid-summer, which will give it enough nutrients to last the growth period.
Over-fertilizing can lead to an imbalance of nutrients, which can harm the plant's growth. Following the instructions on the fertilizer package and diluting it to half its strength can prevent any adverse effects.
Pruning
Plectranthus phryxotrichus Briq. is known to grow bushy and tall, and it is recommended to prune it regularly to maintain its shape and size. It is also an excellent way to get rid of diseased and damaged leaves.
The best time to prune the plant is during the fall when it goes dormant, although you can still trim it during the growing season. Using sharp pruning shears, cut back the unwanted foliage, twigs and make the desired cuts to help it maintain its shape. Ensure to cut back its stem tip by one-third, which will encourage bushier growth from the sides.
With the right care and attention, your Plectranthus phryxotrichus Briq. plant will reward you with a spectacular display of lush green foliage, vibrant flowers, and a calming scent.
Propagation of Plectranthus phryxotrichus Briq.

Propagation by Seeds
Plectranthus phryxotrichus Briq. can be propagated by seeds. Sow seeds in a regular potting mix and keep the soil consistently moist. Seeds of this plant will germinate within one to two weeks. After germination, the seedlings can be transplanted into individual pots or containers.
Propagation by Stem Cuttings
Stem cuttings are a common and efficient way to propagate Plectranthus phryxotrichus Briq. Take a 10-centimeter cutting from healthy new growth of a mature plant, making sure there are several sets of leaves intact. Remove the lower leaves and dip the cutting into rooting hormone. Plant the cutting in a well-draining potting mix and keep the soil consistently moist. The rooting of cuttings usually takes 4 to 6 weeks. After rooting, pot the cuttings in individual pots or containers.
Propagation by Division
Plectranthus phryxotrichus Briq. can also be propagated by division. Divide mature plants in spring or early autumn. Carefully remove the plant from its container or bed and separate individual stems and roots. Make sure each division has several sets of leaves and roots intact. Plant each division in well-draining potting mix and provide adequate water and light.
Disease Management
Some common diseases that might affect Plectranthus phryxotrichus Briq. include:
- Leaf spots: Leaf spots are usually caused by fungal infections. These can be treated by removing affected leaves and improving air circulation around the plant.
- Root rot: Root rot is caused by overwatering and poorly drained soil. To manage this disease, it is important to provide good drainage and avoid watering too much.
