How To Fill A Raised Garden Bed On A Budget?

I have 4 8x4x2 raised garden beds. I am trying to figure out the best way to fill them and possibly stay under $400. I did not realize how expensive soil can get. What is the best thing to put in raised garden beds? I live in northern Utah so it gets very dry and hot here.

I recommend to use the layering method to reduce soil costs and improve long-term structure. Start with about a foot, 12–16 inches of woody debris (logs, branches, sticks) for water retention and airflow. Add 8–12 inches of organic matter (shredded leaves, straw, grass clippings, cardboard), then top with 6–8 inches of compost/topsoil blend in a 1:1 ratio. Source bulk materials locally from landscaping yards or city compost programs to keep it as cheap as possible. Finish with about 2–4 inches of mulch to reduce evaporation. You can also supplement that with coconut coir or peat moss to improve moisture retention. This method holds water efficiently, resists compaction, and thrives in high heat and low rainfall. Ideal for a more dry climate.
