When selecting potting soil, look for a mix that's specifically designed for containers and has a balanced nutrient profile. Avoid using soil from your garden, as it may compact too much in the planter and hinder drainage.

Instead, choose a soil mix that's formulated to retain moisture but still drain excess water. By following these soil preparation tips, you'll create a healthy environment for your plants to thrive in.

Gravel Layer Benefits

By incorporating a gravel layer, you create a stable base that allows water to percolate through, reducing the risk of waterlogged soil and associated root problems. This vital step enhances drainage efficiency, ensuring your plants receive the right amount of moisture without becoming waterlogged. As you add the gravel, visualize the excess water flowing freely through the porous material, preventing water from accumulating at the soil surface.

The gravel layer also serves as an effective barrier against weeds, preventing them from growing up through the soil. This means less maintenance for you, as you won't need to constantly remove unwanted growth. By controlling weed growth, you're also reducing competition for nutrients and resources, giving your plants a better chance to thrive.

As you prepare the gravel layer, make sure to spread it evenly, about 2-3 inches deep. This will provide the necessary depth for ideal drainage and weed prevention.

With this solid foundation in place, you're ready to add the soil and start planting your chosen greenery.
