Hello xdhunter and welcome to the The Community. We are glad that you are here.
The table below shows how much garden soil you will need to purchase to fill a 4 ft x 4 ft raised bed. The “deeper” the raised bed, the more soil you will need. Remember that the plants that you are planting will also take up space in the raised bed. The soil quantities shown are approximate.
For best results, incorporate 20-30% soil amendment, manure, or compost into your mixture – your plants will love it! Adjust the soil quantity accordingly. Most bagged goods are sold as 1 cu ft or 2 cu ft in the Outside Garden Department at your local Home Depot store.
Some soils include fertilizer, however you may need to apply additional fertilizer (slow-release granular or water soluble) depending upon your plants.
Over time, the soil may become compact and you will want to add additional soil. You will definitely want to “turn” the soil to aerate it before the next growing season; you will add more soil at that time.
Best wishes on your project.
