| Aug 24, 2023 at 8:53 | comment | added | daw | if you move the left tree in the first row of your original answer down three rows then you get a symmetric solution with 7 rows (and not more) | |
| Aug 24, 2023 at 7:51 | comment | added | Stiv | This new solution makes 8 rows (not just 7), with the long diagonal from bottom left to top right... (This is also achieved by just positioning the 9 trees in a 3x3 square grid.) | |

Add symmetric solution
