Ocimum basilicum, commonly known as basil, is a herbaceous plant in the family Lamiaceae. It is native to tropical regions from central Africa to Southeast Asia. Basil is an annual or sometimes a short-lived perennial subshrub. It is widely cultivated for its aromatic leaves, which are used in cooking. Basil thrives in warm, seasonally dry climates.
Basil requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and high humidity. Water the plant when the soil feels dry to the touch, but avoid waterlogging. Basil can be grown both indoors and outdoors, making it a versatile herb for various environments.
収穫
Ocimum basilicum, commonly known as basil, should be harvested just before the plant starts to flower for the best flavor. This typically occurs about 70 days after planting. To harvest, use sharp scissors or pruning shears to cut the stems just above a pair of leaves, which encourages the plant to branch out and continue growing. Regular harvesting will promote a bushier plant and prevent it from going to seed too quickly. It's best to harvest in the morning after the dew has dried but before the heat of the day to preserve the essential oils in the leaves.
土壌
Basil prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is rich in organic matter to support its nutrient needs. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize basil every 4-6 weeks during the growing season to promote healthy growth and abundant foliage.
植え替え
Repot basil when it outgrows its current container, typically once a year. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.
伝搬
Basil can be easily propagated from cuttings or seeds. For cuttings, take a 4-inch stem cutting just below a leaf node, remove the lower leaves, and place it in water or moist soil. For seeds, sow them in a seed-starting mix and keep the soil moist until germination.
剪定
Prune basil regularly to encourage bushy growth and prevent it from flowering too early. Pinch off the top sets of leaves every few weeks to promote lateral growth. Remove any flower buds to keep the plant focused on leaf production.
毒性
Basil is non-toxic to pets and humans. It is safe to grow in households with animals and children. However, consuming large quantities of basil essential oil can be harmful.
追加
To extend the harvest period, consider succession planting by sowing new seeds every few weeks. This ensures a continuous supply of fresh basil leaves throughout the growing season.
