To start a garden, choose a sunny location with good soil. Clear the area of weeds and debris, then loosen the soil with a shovel or tiller. Select plants that suit your climate and space, and arrange them according to their sunlight and water needs. Next, plant your seeds or seedlings according to the instructions on their labels. Water them gently to avoid washing away the soil. Regularly check for pests and diseases, and maintain a consistent watering schedule. As your garden grows, enjoy the process and make adjustments as needed to ensure healthy plants.
