Euphorbia tirucalli, commonly known as the Pencil Cactus or Milk Bush, is a semisucculent shrub or tree native to dry shrublands and desert regions of Africa and India. It is known for its slender, pencil-like branches and can grow up to 30 feet tall in its natural habitat. The plant produces a toxic, milky sap that can cause skin irritation and is harmful if ingested.
Euphorbia tirucalli thrives in bright, direct sunlight and prefers warm temperatures. It can tolerate low humidity and requires minimal watering, making it ideal for dry climates. Ensure the plant is placed in a well-ventilated area to prevent moisture buildup.
土壌
This plant prefers sandy, well-draining soil. A cactus or succulent mix is ideal. Ensure the soil dries out completely between waterings to prevent root rot.
肥料
Fertilize Euphorbia tirucalli with a balanced 10-10-10 fertilizer during the growing season. Apply the fertilizer sparingly, as the plant does not require heavy feeding.
植え替え
Repot the plant every 2-3 years or when it outgrows its current container. Use a well-draining soil mix and a pot with drainage holes. Handle the plant carefully to avoid contact with its toxic sap.
伝搬
Propagate Euphorbia tirucalli through stem cuttings. Allow the cuttings to dry and callous for a few days before planting them in well-draining soil. Propagation is best done during the warmer months.
剪定
Prune the plant to maintain its shape and remove any dead or damaged branches. Wear gloves and protective clothing to avoid contact with the toxic sap. Pruning can be done at any time of the year.
毒性
Euphorbia tirucalli is highly toxic to both pets and humans. The milky sap can cause severe skin irritation, and ingestion can lead to serious health issues. Keep the plant out of reach of children and pets.
追加
