Yes, basil can be planted outdoors directly from seeds. Choose a sunny location with well-draining soil. Sow the seeds about 1/4 inch deep and cover them lightly with soil. Water gently to keep the soil moist until the seeds germinate. Once the seedlings have grown a few inches tall, thin them to provide enough space for proper growth. Regularly water and care for the plants, and you will soon have a flourishing basil garden.
