Use a high-quality potting mix designed for container gardening. It’s lighter than garden soil, providing better aeration and drainage, which is crucial for preventing waterlogging that can lead to wood rot. Adding organic matter, such as compost or peat moss, improves the mix’s water-holding capacity and nutrient content. For plants with specific needs, adjust the soil composition accordingly—such as adding sand for cacti or more organic matter for moisture-loving plants. Avoid using heavy garden soil, which can compact over time and hinder proper drainage.
