There are so many benefits to having plants in your office or home and they look great! To improve health & reduce fatigue & stress, place 1 large plant (8-inch diameter pot or larger) every 129 sqft. In an office, position plants so each person has greenery in view. To purify air, use 15 to 18 plants in 6-8" diameter pots for 1,800sqft. That’s roughly 1 plant every 100 sqft. Ivy Thyme Design is your local plantscape expert. www.ivythymedesign.ca
