Step 1: Find an Area With Bad Soil
Areas with bad soil are very good places for hugelkulturs. The plants will not be able to grow in the bad soil so you need to add other things to it. Dig a hole about 20 feet long, 3 feet across, and 2 feet deep.
Step 2: Preparation
Fill the hole with biodegrading wood, straw, and soil. The materials will decompose and provide good nutrients for the plants.
Step 3: Plant Seeds
After digging the trench, cover the wood with soil, and plant the seeds.
Step 4: Water Plants
When the plants start growing, water them accordingly.
Step 5: Weed Plants
Not only will the plants grow, but weeds will too. Pick all the weeds out by the roots.
