Grass borders: Natural grassy areas are best if you want lots of species. If you prefer a neater look, simply frame the natural area with a meter-wide lawn border. This supports biodiversity and looks attractive.
Breathe easy: Buildings with closed windows often have low humidity, which can lead to a dry throat. For a natural solution to this problem, simply plant some nutgrass (Cyperus eragrostis). If the hygrometer reads 45 percent, your room has perfect humidity.
