Gardening is the practice of cultivating plants like flowers, vegetables, fruits, and herbs in a designated space for beauty, food, medicine, or habitat, offering significant physical exercise, stress relief, and mental well-being benefits through activities like planting, watering, and weeding, and can be done indoors, outdoors, or even in containers. Key aspects include matching plants to your climate, proper watering techniques (soil, not leaves), enriching soil, and finding the right balance of sun, water, and fertile soil to help plants thrive.
