Drainage is essential for ensuring that your plants have access to the oxygen and water they need to thrive. Poor drainage can lead to oversaturation of the soil, which can stunt plant growth. Good drainage is especially important when growing plants in a raised garden bed.

The ideal potting mix contains a combination of three main ingredients: topsoil, compost, and potting soil. The ratios of these ingredients will vary depending on the type of plants you are potting and the climate you live in. For most situations, however, we recommend a mix of 60% topsoil, 30% compost, and 10% potting soil. Topsoil is essential for providing nutrients and anchoring roots, while compost helps to aerate the soil and improve drainage. Potting soil, a soilless mix that often contains peat moss, perlite, and/or vermiculite, is ideal for container gardening because it is lightweight and provides good drainage.
