Thomas Ogren considers himself a life-long plant geek. He's been gardening since age five, and by age seven, he began grafting trees.
The San Luis Obispo resident continued with his passion for horticulture as a professor for more than 20 years.
When Orgen and his wife moved to the Central Coast, he says he wanted to make their yard allergy-friendly, to help with her allergies. His many years of research on that front eventually led to his new book The Allergy-Fighting Garden.
Ogren explains ways to audit your garden's allergens and make your garden 'allergy-fighting.' He also believes cities can do more to make the surrounding air better for residents.
