General Appearance
Euphorbia graveolens N.E.Br. is a succulent plant that can grow up to two meters tall. It has a cylindrical stem that is made up of numerous ridges with a grey-green color. The stem is covered with small spines and has several branches that form a candelabrum-like shape. The plant's leaves are small and elliptical, which fall off quickly. Its flowers are small and yellow, growing in clusters on the end of each stem. The plant produces milky sap, which can be poisonous to some animals.
Light Requirements
Euphorbia graveolens N.E.Br. thrives in bright, indirect light. It tolerates partial shade, especially during the hottest parts of the day, but direct sunlight for prolonged periods can damage the plant. If grown indoors, it should be placed close to a window that receives adequate sunlight. However, it should not be exposed to hot, direct sunlight through a window as this can scorch the leaves.
Temperature Requirements
Euphorbia graveolens N.E.Br. is native to regions that experience warm to hot temperatures. Therefore, it grows best in warm to hot conditions. The ideal temperature range for this plant is between 60°F to 80°F (15.5°C to 26.5°C). Below 50°F (10°C), it can experience leaf drop and other cold damage.
Soil Requirements
The soil used for Euphorbia graveolens N.E.Br. should be well-draining but also have the ability to retain some moisture. A mix of 50% regular potting soil and 50% perlite or sand does an excellent job of providing the necessary balance of drainage and moisture. At least once a month, the topsoil should be amended with an all-purpose fertilizer to provide essential nutrients to the plant.
Cultivation
Euphorbia graveolens N.E.Br. is a succulent plant that requires appropriate conditions for growth. It can be grown from seed or cuttings, and it needs well-drained and sandy soil. The plant thrives in full sunlight, and it should be protected from extreme temperatures.
Watering needs
When it comes to watering, it is essential to let the soil dry out between watering sessions. Over-watering could lead to root rot, which might damage the plant. During the growing season, the plant should be watered moderately, ensuring that the soil is slightly moist. During the winter season, watering should be reduced, allowing the soil to dry out more thoroughly.
Fertilization
Euphorbia graveolens N.E.Br. is a relatively low-maintenance plant, but proper fertilization can help increase its growth rate. The plant should be fertilized during the growing season, typically from spring until late summer. A balanced fertilizer with an NPK ratio of 10-10-10 can be applied, diluted according to the package instructions. It is recommended to avoid fertilizing during the winter season.
Pruning
Pruning is not required for Euphorbia graveolens N.E.Br., but it can help shape the plant and encourage new growth. If the plant becomes leggy and loses its shape, it can be pruned during the growing season. It is recommended to wear gloves when handling the plant as its sap is toxic and can cause skin irritation. When pruning, it is essential to use clean tools to avoid spreading diseases.
Propagation of Euphorbia graveolens N.E.Br
Euphorbia graveolens N.E.Br., also known as the Lavender Spurge, is a succulent plant native to Southern Africa. It is a popular houseplant due to its attractive foliage and ease of propagation.
Propagation Methods
Euphorbia graveolens can be propagated by stem cuttings or seeds. Both methods are relatively easy and yield fast results.
Stem cuttings
The stem cuttings method is the most common and easiest method to propagate Euphorbia graveolens. The best time to take a stem cutting is during the plant's active growing season in spring or summer.
To propagate using stem cuttings, follow these steps:
- Use a clean, sharp knife or scissors to cut a stem from the parent plant.
- Let the cutting dry in a cool, shaded place for a few days to allow it to develop a callus.
- Plant the cutting in a well-draining soil mix and water it until the soil is moist.
- Place the cutting in a bright but indirect light and avoid direct sunlight.
- Keep the soil moist and avoid overwatering as it can cause the cutting to rot.
- The cutting should start developing roots within two to three weeks.
Seeds
Seeds can also be used to propagate Euphorbia graveolens. To propagate using seeds, follow these steps:
- Collect seeds from the parent plant when the seed capsules are mature.
- Clean the seeds and store them in a cool, dry place until planting.
- Sow the seeds in a well-draining soil mix and cover them with a light layer of soil.
- Water the soil until it is moist and place the pot in a bright, warm place but avoid direct sunlight.
- The seeds should germinate within two to three weeks.
Propagation of Euphorbia graveolens using either method is an easy and rewarding process that can be done by both beginners and experienced gardeners.
Disease and Pest Management for Euphorbia graveolens N.E.Br.

However, like most plant species, it is also susceptible to different pests and diseases. Here are some common diseases and pests that might affect Euphorbia graveolens N.E.Br. and suggestions on how to manage them:
Diseases:
1. Root Rot: Root rot is a fungal disease that affects plants grown in poorly-draining soil or damp conditions. Symptoms include yellowing or wilted leaves and a foul smell. To control root rot, avoid over-watering the plant and ensure proper drainage. Remove the affected plant parts and replant the healthy parts in a new pot with fresh soil.
2. Leaf Spot: Leaf spot is a fungal disease that causes brown or black spots on the leaves. This disease is prevalent in damp conditions and is easily spread by water. To manage leaf spot, remove the affected leaves and ensure proper air circulation around the plant. Avoid overhead watering and apply a fungicide spray to the plant's leaves.
Pests:
1. Mealybugs: Mealybugs are small white insects that feed on the sap of the plant, causing damage to the leaves, stems, and root. To manage mealybugs, use a cotton swab soaked in alcohol to remove them from the plant. You can also apply neem oil or insecticidal soap to control their population.
2. Spider Mites: Spider mites are tiny red insects that suck the sap from the leaves of the plant and produce a web-like substance on the leaves. To manage spider mites, spray the plant with a jet of water to wash off the webs and mites. You can also use an insecticidal soap or neem oil spray to control their population.
By following the tips mentioned above, you can effectively manage the diseases and pests that might affect Euphorbia graveolens N.E.Br. and ensure that your plant remains healthy and vibrant.
