Wasps: Garden Friends or Foes?
by Blake Layton

When most people think of wasps, they think of paper wasps, and they probably think of them only as pests because of unpleasant past encounters with these stinging insects. However, the world of wasps is much larger and more complex than this! Our gardens abound with hundreds of species of wasps that vary greatly in size and life habits. Most of the wasps in our gardens are tiny, parasitic species that do not sting people and go largely unnoticed. These are definitely friends because they help control pest insects. There is also a group of wasps known as sawflies whose larvae look like caterpillars and feed on plants. These are usually foes because they damage landscape plants. Two other groups of wasps are the social wasps, such as paper wasps, and the solitary wasps, such as mud daubers and cicada killers. Wasps in both these groups are capable of stinging, and they definitely qualify as foes when they do so, but paper wasps also have a beneficial side.   >> read article

The Best Defense
Managing weeds in flowerbeds
by Ron Strahan

Gardeners take pride in the appearance of their landscapes. However, nothing detracts from the beauty of flowerbeds like weeds. Along with being aesthetically displeasing, weeds in flowerbeds compete with desirable plants for water, nutrients and light. If weeds are out of control, expect fewer flowers and more headaches. For most people, backbreaking hand removal is relied upon exclusively to remove weed problems. Hand pulling may be successful for a few weeds, but for most weed problems it is only partially effective.   >> read article

Caterpillar Calamities
by Blake Layton

Every gardener has experienced it, usually more times than they can count. You walk into the garden and discover a plant that’s been defoliated or otherwise damaged by caterpillars. The canna leaves are riddled with holes, the cabbage leaves look like lace, half the tomatoes have worms in the fruit, or the azaleas have been stripped of their leaves. How could this happen so quickly?   >> read article

Cantankerous Cankers
by Christopher Starbuck

The term “canker” refers to a lesion on a twig, branch or stem, usually caused by a bacterial or fungal pathogen. The appearance of cankers varies, depending on the host and the pathogen. Often, the bark of the affected stem or trunk is sunken and discolored. Fluids may ooze from a canker or fungal fruiting structures may appear on the bark covering or surrounding the lesion. In some cases, lesions remain small and isolated, causing no major problems for the host plant. In other cases, the canker spreads widely, causing death of twigs, branches or even the main trunks of trees. The best known example of the destructive potential of a canker disease is chestnut blight, caused by the fungus Endothia parasitica, which caused the virtual extinction of the American chestnut within 40 years of its accidental introduction to the United States in about 1900.   >> read article

Smart Gardening
by Dr. Ayanava Majumdar

Integrated pest management or IPM is a smart way of managing insect pests for economic and environmental benefits. IPM starts with the timely detection and correct identification of pests, leading to intervention using multiple control tactics. Insect traps can be used as a tool for timely pest detection and decision-making in home or commercial settings.   >> read article

Building a Scarier Scarecrow
by Cindy Shapton

If you have a garden, it’s more than likely that you also have a pest or three. It should be no surprise that pests and critters like our yards and gardens as much, or more, than we do. We are encouraged to invite wildlife into our yards and gardens because we love seeing them, and, in theory, they help balance our desire for our garden and nature to coexist. But what happens when they go rogue and start eating, digging and destroying all of our hard work?

Scaring them away, or we could say gently discouraging, wild and sometimes not-so-wild critters to “Step away from the garden,” is always a first and sometimes successful option.   >> read article

Move the Plants, Not the Pests
by Douglas Spilker, Ph.D.

Container gardening is one of the fastest growing sectors of the gardening world – and why not? Containers can be grown where traditional gardens cannot, such as apartment balconies, courtyards, decks and patios. Since most containers are portable, there is a strong temptation to bring this instant landscape and color into the home once autumn transitions into the cold of winter. However, in addition to the preparation of the plants’ horticultural needs, extra precautions need to be taken to ensure that no unwanted visitors hitchhike into your home on these container plants and jeopardize the health of your current houseplants or cause a nuisance in the home.   >> read article

Midsummer Checkup
by Charlotte Kidd

Tall, multicolored ‘Granny’s Bouquet’ zinnias flourish in the sunny border. We’ve been clipping them regularly for the table, which encourages new flowering. Heritage garden roses are into their second or third flush. Landscape roses continue strong and brighter than ever. Grape, patio and large luscious tomatoes are at peak production. Yellow and green summer squash are so prolific that neighbors walk the other way when they see you carrying yet another vegetable.

July and August also can bring out the worst in marginally healthy plants. Plants are a collection of living cells, just like us. We’re more susceptible to going downhill fast when stressed, underfed, dehydrated, injured, too hot or too cold.   >> read article
