Eustoma russellianum, commonly known as Lisianthus or Prairie Gentian, is a beautiful flowering plant native to the southern United States, Mexico, and the Caribbean. It is known for its rose-like blooms that come in a variety of colors including white, pink, purple, and blue. The plant can be annual or biennial and prefers temperate climates.
Lisianthus thrives in bright, indirect light and moderate temperatures. It prefers moderate humidity and should be watered when the top layer of soil dries out. Avoid overwatering as it can lead to root rot. The plant can be grown both indoors and outdoors, making it versatile for different settings.
土壤
Lisianthus prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil has good drainage to prevent waterlogging, which can harm the plant. A mix of garden soil with some sand and organic matter works well.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and abundant blooms.
换盆
Repot Lisianthus when it outgrows its current container, usually once a year. Choose a pot that is one size larger and ensure it has good drainage. Gently remove the plant from its old pot, place it in the new one, and fill with fresh soil.
传播
Lisianthus can be propagated from seeds or cuttings. Sow seeds indoors 10-12 weeks before the last frost date. For cuttings, take a healthy stem cutting and root it in a moist growing medium. Keep the cuttings in a warm, bright location until they establish roots.
修剪
Prune Lisianthus to encourage bushier growth and more blooms. Remove spent flowers and any dead or yellowing leaves. Pruning can be done throughout the growing season to maintain the plant's shape and health.
毒性
Lisianthus is not toxic to pets or humans, making it a safe choice for households with animals and children.
