Euphorbia marginata, commonly known as Snow-on-the-Mountain, is a striking annual plant native to the central United States. It is known for its variegated white and green leaves and small white flowers. This plant is often used in gardens for its ornamental value and can grow up to 1 meter tall.
Euphorbia marginata thrives in full sun and prefers moderate temperatures. It requires well-draining soil and should be watered sparingly, allowing the soil to dry out between waterings. This plant can tolerate low humidity and does not require high nutrient levels.
土壌
Euphorbia marginata prefers well-draining loam soil. It can tolerate a range of soil types but performs best in soil that is not too rich in nutrients. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied sparingly during the growing season. Over-fertilization should be avoided as it can lead to excessive foliage growth at the expense of flowers.
植え替え
Repotting is generally not necessary for Euphorbia marginata as it is an annual plant. However, if grown in containers, it can be repotted in fresh soil at the beginning of the growing season.
伝搬
Euphorbia marginata can be propagated by seeds. Sow the seeds directly in the garden after the last frost or start them indoors a few weeks before the last frost date. Ensure the seeds are lightly covered with soil and kept moist until germination.
剪定
Pruning is beneficial for maintaining the shape and encouraging bushier growth. Dead or damaged stems should be removed, and the plant can be pinched back to promote branching.
毒性
Euphorbia marginata is toxic to pets and humans. The sap can cause skin irritation and, if ingested, can lead to gastrointestinal distress. Care should be taken when handling the plant, and it should be kept out of reach of children and pets.
