Sack Garden Step 3
It is helpful to roll the outside of the sack so that it’s easy to keep taut and unroll as you fill the sack. Continue to pack the soil well until the sack is full. Water the soil thoroughly and check to make sure that it will remain upright. If building a sack garden on a hillside, add a brace on the downward side of the sack garden with logs, stone, brick, or other sturdy material (red arrow).
