Eliminate Stilt Grass Now

A Window of Opportunity Your window to destroy any Japanese stilt grass on your property closes when its seeds emerge in late August through October.  This tenacious, invasive grass has all the adaptations it needs to gobble up real estate in private yards, public spaces, and in woodlands across America.  But your swift action now, before this year’s seeds ripen, can help stop its spread.     Japanese stilt grass, Microstegium vimineum, is an annual that will die back with...

In Defense of Ivy

  Ivy:  Hero or Villain? English ivy, celebrated in hymns and carols, rich in history and tradition, may be among the most hated of ‘imported’ plants for some American gardeners.  Native plant enthusiasts may call ivy a ‘noxious weed.’  And now, thanks to a new state law, HB 1941, which will go into effect in Virginia in January of 2027, horticultural retailers will be required to label ivy as an invasive plant and suggest alternatives whenever it is sold directly...

Common Invasive Plants Every Master Gardener Should Know

  The question of invasive plants is an interesting one, in part because the list keeps growing.  Some of the plants on this list may surprise you because they are so commonly found in our local yards and landscapes.  A few plants have just been added to the list over the past year. While some, like stilt grass are noxious weeds, many of these ornamental plants are still available in the nursery trade.  Several are beloved by local butterflies and...

Managing Rain and Run-Off with the Right Plantings

The Elements of Life Water, light, and air fuel our lives.  We depend on them, as does every plant and animal.  Light energy powers the chemistry of photosynthesis to transform elements like carbon and hydrogen into sugars, food.  Oxygen fuels the production of life energy in every living cell.  And water fills every cell of every living creature; gives us sap and blood; powers every process of life.  There is no life, not even the tiniest microbe, without water.  ...

A History of Our War With Plants

  “I use only native plants, native to the planet Earth.  I am using indigenous plants; they are indigenous to this part of the universe.” Bill Mollison, Founder and Director of The Permaculture Institute     In the Beginning… Let’s begin with the obvious:  we live within an ever-changing ecosystem.  Europeans came to North America more than four centuries ago, cutting trees, planting fields, building homes and roads.  Native Americans also cut trees, built homes, planted fields, hunted, and lived...

The Problems with Nandina

  What’s the big fuss about Nandina? It is attractive, easy to grow, and can be found growing throughout older neighborhoods in our area. Its berries (drupes) turn bright red in October, just in time to brighten up the winter landscape.  Some people cut the red fruit for use in holiday decorations. Nandina’s foliage may even turn bright scarlet after frost, depending on the cultivar. It can be a beautiful and useful plant. Nandina is so tough and versatile that...

Climbing Vines in Coastal Virginia

  Vines of all types love our Coastal Virginia climate.  Many different species thrive in summer’s heat and humidity, growing by inches each day.  They creep across the ground until they encounter something to climb.  Their tender, flexible tips reach up and out in search of a support, and then they climb. Benefits of Vines All vines in our area produce flowers and seeds.  While some flowers are bright and showy, like the bright orange trumpet creeper, others are nearly...

Phragmites in Local Wetlands- Updated

  “… despite its bad reputation, Phragmites provides many benefits that are generally unknown and unappreciated. After studying salt marsh ecology and the impacts of stressors, including invasive plants, for many years, I have concluded that removing this invasive species wherever it is found – especially along vulnerable coastlines – is a very expensive and often foolish procedure.” Dr. Judith Weis, Professor Emerita in Biological Sciences Rutgers University   Historically, Phragmites Are Part an Important Part of the Ecosystem Our...

Landscaping With Herbs Part II:  Deciduous Perennial Herbs

What is an Herb? Why is mint an herb, but clover isn’t?  Have you ever given it much thought?  Botanically, any plant with a soft stem, that dies back in winter, is ‘herbaceous.’  Were you give a stack of a dozen cards, each with the name and picture of a plant, could you sort them into ‘herbs’ and ‘not herbs’? If asked, most of us could probably name at least five herbs.  Those used in cooking, like basil and thyme...
