Light Requirements
Euphorbia pubiglans N.E.Br. requires bright, indirect sunlight for optimal growth. Direct sunlight may scorch the leaves, so it is best to place the plant near a window that receives filtered light or in a spot with bright, indirect light.
Temperature Requirements
This plant is native to South Africa and thrives in warm temperatures. Ideal temperature range for Euphorbia pubiglans N.E.Br. is between 60-85°F (15-29°C). Temperatures below 50°F (10°C) may cause the plant to suffer and temperatures below 40°F (4°C) can be fatal. It is important to keep the plant away from air conditioning units and cold drafts.
Soil Requirements
Well-draining soil is important for the health of Euphorbia pubiglans N.E.Br. Choose a soil mixture that is specifically formulated for cacti and succulents to ensure proper drainage and aeration. Soil that is too compacted and retains moisture can lead to root rot and other fungal diseases. A mixture of sand, perlite, and peat moss is recommended. It is important to let the soil dry out completely between waterings.
Cultivation Methods
Euphorbia pubiglans N.E.Br. is a plant that thrives in well-draining soil and requires a sunny location to grow. If you live in a region with a hot and dry climate, make sure to provide shade during the hottest parts of the day. The plant is also sensitive to frost, so it's best to avoid planting it in cold climates.
Watering Needs
Euphorbia pubiglans N.E.Br. is a drought-tolerant plant, and overwatering can harm it. Water your plant moderately, about once every two weeks throughout the growing season and less frequently in the dormant season. The plant does well when the soil dries out between watering, and it is best to avoid watering the foliage directly.
Fertilization
This plant does not need heavy fertilization to thrive. You can feed it twice a year during the growing season, first in the spring and then in late summer or early fall. Using a balanced fertilizer with equal ratios of nitrogen, phosphorus, and potassium is ideal.
Pruning
Euphorbia pubiglans N.E.Br. requires minimal pruning. It's best to prune it only to remove dead or damaged branches. When pruning, be sure to wear gloves and eye protection as the plant's sap can cause skin and eye irritation. If the plant becomes too tall or leggy, you can prune it to promote a bushier growth, but avoid over-pruning as it can damage the plant
Propagation of Euphorbia pubiglans N.E.Br.
Euphorbia pubiglans N.E.Br., commonly referred to as the "Ghost Euphorbia," is a unique succulent with silver-gray stems covered in small thorns. It is native to Southern Africa and is heavily sought after by plant collectors for its striking appearance.
Propagation Methods
E. pubiglans can be propagated by several methods, including stem cuttings, seed, and division.
Stem Cuttings
To propagate E. pubiglans through stem cuttings, use a sterilized knife or scissors to cut a stem section between 5-10cm long. Allow the cutting to dry out for a few days before planting in a well-draining soil mix. Place the cutting in a bright area but protect it from direct sunlight until it has established roots.
Seed
Seeds can be collected from mature E. pubiglans plants and sowed in a well-draining soil mix. Keep the soil moist until germination occurs, and then gradually reduce watering until the plant is fully established.
Division
Mature E. pubiglans plants can also be divided into multiple plants. Carefully remove the plant from its pot and gently separate the stems, being careful not to damage the roots. Each stem with a healthy root system can be potted into its own container.
Propagation of E. pubiglans can be a relatively easy process, especially when using stem cuttings or division. With proper care and attention, your E. pubiglans collection can quickly grow into an impressive display.

Spider Mites: Spider mites are the most common pests that attack the Euphorbia pubiglans N.E.Br. They are tiny and difficult to spot in the initial stages of an infestation. However, with time, you can see webbing on the leaves and the tender shoots. Spider mites suck the sap from the plant's leaves, making them yellow and less healthy.
Mealybugs: Mealybugs appear as white, furry patches on the plant. They also suck sap from the plant, which makes the leaves yellow and stunted. Infested plants can become stunted and may not grow as well as healthy plants.
Scale insects: Scale insects can be found on the stems and leaves of the plant. They suck the sap from the plant and reduce its vigor. They also secrete a sticky substance called honeydew, which attracts ants and other pests.
