Final Thoughts for Gardening Aficionados

Outdoor gardening is not just about cultivating plants; it's about understanding the soil and ensuring what we grow is safe for consumption. While some plants used for phytoremediation can grace our dining tables, others, notably pumpkins, are best left untouched.
