That is a bit tricky since your content is divided in rows. It's still achievable though (see secure note). Please follow the steps below:
1. First, apply the leaf background to the first row in the section and not the column and then set the background position to top.
2. Set the top, left and right borders of the first row individually.
3. Set the left and right borders of the middle rows.
4. Set the left, right and bottom borders of the last row.
Hope that helps.
