Using the size of your raised garden bed, calculate the quantity of soil you’ll need (cubic feet/yards). Keep in mind that the total should include the soil and compost mixture. 60 percent topsoil, 30 percent compost, and 10% potting soil should make up your soil mix. Because soil might be costly, it is recommended that you use the Hugelkultur technique to save money. Once you’ve got the dirt, fill it almost to the top. The precise quantity depends on the sort of plants you’ll be cultivating as well as your own preferences. Avoid tilling the soil since this will cause it to dry out.
