Black Walnut Tree Bears Fruit

Unlike many gardeners, I invite squirrels into my yard. I know there are plenty of gardeners out there who spend a lot of time and money to keep these furry fiends out of their vegetable gardens, but squirrels are a part of the scenery around here. And they’re just so darn entertaining. I know that […]

How to Plant and Grow a Healthy Tree

Why would anyone intentionally kill a new tree? That’s the thought that crossed my mind when I saw this little tree while walking through my neighborhood. Obviously, these folks wanted to grow a tree. They invested money in buying a tree, they spent time digging a planting hole and they even took time to stake […]

Start the Gardening Season with the New Edition of The Colorado Gardener’s Companion

The second edition of my first book is ready in time for gardening season! I worked over the winter months to fill this new edition with more of everything to help Colorado gardeners grow great gardens starting now. The Denver Post newspaper calls the new edition of my gardening book an “an essential manual” for […]

Emerald Ash Borer will Ruin our Urban Forest

The Emerald Ash Borer, first discovered in Boulder in 2013, is considered the most destructive pest in North America. The future looks bleak for ash trees in the South Platte drainage area of Colorado. The tiny Emerald Ash Borer (EAB) is such a destructive insect pest that it will most likely ruin the urban forest […]

How Northern Flickers Build Their Nest

A happy couple of Red-shafted Northern Flickers took just a week to create this impressive nest. I was away in Gillette, Wyo., giving the keynote presentation at the Native Plants Speaker’s Series when I called home to check in. John brought me up-to-date on what was happening at the homestead and before ending the call […]

Bonsai Basics for Growing Miniature Trees

The new Bill Hosokawa Memorial Bonsai Pavilion and Tea Garden at the Denver Botanic Gardens is now open. Here’s a little information about the ancient art of bonsai. Despite their size, bonsai are not a species of dwarf tree, but the name of the art of growing trees in miniature. The Chinese originated bonsai over […]

Early Blooms Good for Bees

The earliest blooming shrub in my yard is this cold-hardy Nanking cherry. Last week I wrote about the Cherry Blossom festival in Washington being two weeks ahead of schedule because the trees are already in full bloom. The same thing is happening in my backyard with a mini-version of the annual event. The lovely white […]

Glimpse of Cherry Blossom Beauty

Last April I was in Washington, D.C., and was fortunate to see one lone cherry tree in full bloom. These famous trees that line the Tidal Basin typically bloom from March 26 to April 10. I stopped by on April 11 and almost all the blossoms were off the trees because of a big windstorm […]

Shady Places Make for Creative Spaces

Last August I had the pleasure of touring one of the most delightful shade gardens I’ve seen. It gave me dozens of ideas for adding shade-loving plants to my landscape. Perhaps it will inspire you, too. The towering trees that frame this stately Indianapolis property provide plenty of cooling shade in the summer…and offer plenty […]
