Lavandula latifolia, commonly known as spike lavender, is a subshrub in the family Lamiaceae. Native to the Mediterranean region, it thrives in temperate climates and is known for its fragrant flowers and essential oils. The plant undergoes a dormancy period during the winter months.
Lavandula latifolia requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and low humidity. Water the plant when the soil is almost completely dry, and ensure good air circulation to prevent fungal diseases.
土壌
This plant prefers well-draining loamy soil. It can tolerate poor soil conditions but thrives best in soil with moderate nutrient concentration. Ensure the soil dries out almost completely between waterings to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-5. Fertilize sparingly, about once a month during the growing season, to avoid over-fertilization which can harm the plant.
植え替え
Repot Lavandula latifolia every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Repot in the spring before the growing season begins.
伝搬
Propagate Lavandula latifolia through cuttings or seeds. Take cuttings in late spring or early summer and root them in a well-draining soil mix. Seeds can be sown in the spring.
剪定
Prune the plant after flowering to maintain its shape and encourage new growth. Remove any dead or diseased branches and trim back about one-third of the plant.
毒性
Lavandula latifolia is not toxic to pets or humans. However, ingestion of large quantities may cause mild gastrointestinal upset.
追加
To enhance the fragrance and oil production, ensure the plant receives plenty of sunlight and avoid overwatering. Mulching around the base can help retain moisture and suppress weeds.
