Transform your old wooden barrel into a vibrant cilantro garden that will provide you with a constant supply of this flavorful herb. Cilantro, also known as coriander, is a staple in many cuisines and adds a fresh and citrusy taste to dishes. Fill the barrel with well-draining soil and plant cilantro seedlings or small plants, ensuring they have enough space to grow. Cilantro prefers partial shade, especially in hot climates. Water the garden regularly, keeping the soil evenly moist. Harvest the cilantro leaves as needed, and enjoy their bright flavor in salsas, curries, and other culinary creations.
