Gardening According to Professor Pinterest

I don’t know who first introduced me to Pinterest (I suspect my youngest sister is to blame…) but since I’ve started using this app, I havewater tomatoes loved what it offers: great ideas for new plants, awesome garden designs to inspire the Butchart-style garden I swear I’ll have one day, greenhouse and raised bed garden designs and ideas…and that’s just with the gardening pins; don’t get me started on the recipes!

However, as much as I love the design and plant ideas, one thing drives me absolutely bonkers - the proliferation of “tips” for making your garden grow or dealing with those pesky garden problems. 

bugsprayorganicYou know what I’m talking about.  Posts that claim that if you just mix x, y, and z from your kitchen cabinet, you can “safely” deal with those weeds without using any pesticides or herbicides.  Or plant your seedlings in eggshells.  Or propagate roses by sticking stems in potatoes. And my personal favorite: get sweeter tomatoes by “fertilizing” with sugar. 


potatoes and rosesAs a WSU Master Gardener, one of the things I learned in my training is how to discern a credible/reliable source of gardening advice from those that don’t quite cut the mustard.  When writing a college paper on gardening, what would your instructor think if you quoted Professor Pinterest?

Imagine what it would be like if farmers used Pinterest to guide their decisions for when they would plant and how they would manage insects and weeds.  Farmers from Washington to Florida would plant their peas on President’s Day, stock in Irish Spring soap would sky rocket as farmers chipped the bars up to put around their fields to keep pests as bay, and the farmer’s kitchen might look more like a chemistry lab as they concoct their own (natural!) pesticides.

A good place to start looking for answers is Washington State University Extension’s new gardening website,  Also check with your local WSU Master Gardener program.  Many have clinics and classes where you can learn about gardening, have plant problems diagnosed, and get information you can rely on to address your gardening issues.  Then go back to Professor Pinterest for that awesome garden layout or new plant idea! The environment will thank you for it.

Garden on!

PS...periodically I'll be talking about some of the specific advice you find on Pinterest or other online sources to let you know whether it is true or not.  Keep an eye out for our "Pinterest Fact or Fiction" blog posts!
