Horticultural Myths Exposed

My favorite industry website recently is Linda Chalker-Scott’s Horticultural Myths. Dr. Chalker-Scott is an Extension Urban Horticulturist at the Puyallup Research and Extension Center at Washington State University, and she takes great delight in debunking common and inaccurate beliefs about best practices for trees and other plants. Her one-page myth busters are informative, easy to read, and very entertaining.

I think my favorite is The Myth of Soil Amendments (“When transplanting trees or shrubs into landscapes, amend the backfill soil with organic matter”) but I also love The Myth of Fragile Roots (“You shouldn’t disturb the rootball when transplanting trees and shrubs”) and the Myth of Compost Tea (“Compost tea is an effective alternative to traditional pesticides”: Part 1, Part 2, Part 3 and Part 4).

So much to love!

Dr. Chalker-Scott also has an ongoing blog that she writes with four colleagues called The Garden Professors. And if you happen to be going to the ISA show this year, she’ll be debunking even more horticultural myths in an hour-long session there.
