Monarda didyma, Scarlet bee balm

Monarda, commonly known as bee balm, is a spectacular plant when grown under the right conditions. Given plenty of sunlight and well-draining soil, it can flower from mid-July to late summer. Still, the plant’s annoying propensity to develop powdery mildew often make it an eyesore in the garden.

Years ago, in an effort to distract my middle-school aged daughters, I dragged them to an avant-garde exhibit at Washington, DC’s Hirshhorn Museum.

Needless to say, it left an indelible impression on all of us. Continue reading

Bamboo Gets A Makeover Thanks To A California Garden

The Bamboo Garden at Northern California’s Foothill College

I’ll admit, I’m not a huge fan of bamboo, especially the kind whose roots advance a foot a day and need to be dug out with a crane. But, I was pleasantly surprised this week to have my views on the plant suddenly upended. It all started with a spectacular variety featuring aqua stems I spied growing in my sister-in-law’s garden.

Camellia japonica ‘Cheryl Lynn’

Winter can be a dreary time in the garden, especially on the East Coast. But as soon as the winter-blooming camellias start flowering, I am reminded that everything has its season. These beautiful shrubs wait until late fall to early spring to produce their spectacular lush-petaled blooms. And one of the best places to view them is at Filoli Gardens in the foothills of California’s Santa Cruz Mountains. Continue reading

Spring Bulbs: Still Time To Plant Some Of These 10 Great Varieties

Spring bulbs in a formal garden setting

Yesterday I directed the planting of two thousand spring bulbs. We placed them individually in patterns and our very capable team dug them one-by-one into the ground. When they were finished, we dressed the bulbs with a thick layer of mulch and all stepped back to admire our handiwork. The garden felt as if it were bursting with energy with so much spring promise nestled snuggly underground. Continue reading

Five Reasons Your Trees Are Failing: A Bartlett Tree Expert Speaks Out

Trees are generally admired for their surface beauty, but their health and vigor springs from what’s underground.

His lecture entitled ‘Managing the Landscape Below Ground’ provided a wealth of information about how to improve the life of the trees in our landscape. According to Fite, it all starts with the soil. Continue reading
