I'm an enthusiastic gardener. I learned the art of growing my own food using sustainable gardening techniques from my father, which I still find effective for healthy plant growth. Gardening has become one of my best hobbies ever since I realized its benefits beyond growing my own food. Through experimenting and connecting with nature, I've found gardening to be a therapeutic and relaxing practice.
