Measure the bed dimensions to calculate total volume
Choose a base layer if needed, such as cardboard or hardware cloth
Add a coarse bottom layer for drainage if the bed is very deep
Fill the lower section with branches, logs, or woody debris if using hugelkultur
Add partially decomposed organic matter, leaves, or composted materials
Mix in topsoil with compost for the main planting layer
Use a soil blend suited to your plants, such as garden soil, compost, and aeration material
Fill the bed to about 1 to 2 inches below the top edge
Water the soil thoroughly to help it settle
Top off with more soil if the level drops after watering
Add mulch on top to help retain moisture
Replenish compost and soil each season as the bed settles and nutrients deplete
