Who would have thought that a little green beetle – not even an inch long – would cause billions of dollars in damage and lead to the death of millions of trees? The emerald ash borer (EAB for short, Fig. 1) was first discovered in 2002 (but probably arrived in the late 1990s) near Detroit, MI, and is now present in most of eastern North America (current distribution map from APHIS: https://www.aphis.usda.gov/aphis/ourfocus/planthealth/plant-pest-and-disease-programs/pests-and-diseases/emerald-ash-borer The larvae (young) of this beetle feed on the phloem of ash trees (genus Fraxinus), and their feeding nearly always results in tree death. Oh, and not just one type of ash tree – all of them: white, green, blue, pumpkin…if it’s a Fraxinus species, it’s susceptible to EAB.
How do I know if my ash tree has EAB? If the tree starts declining, or losing foliage and branches, or has a sudden increase in woodpecker populations (they’re trying to find and eat the EAB larvae, and often cause “ash blonding”, Fig. 2), your ash tree may have EAB. It’s important to inspect your tree and look for little D-shaped holes (Fig. 3) – this is where the adults leave the tree once they’re fully developed.
Can I save my tree if it has EAB? Well that depends…if most of the crown still looks healthy, then probably. There are many chemical treatments that work great to both prevent and treat EAB once a tree is infested (link: http://www.emeraldashborer.info/documents/Multistate_EAB_Insecticide_Fact_Sheet.pdf). There are biocontrol agents (other bugs that eat EAB), but these won’t usually save an individual tree – they’re good for keeping overall populations in check, and are most often used in natural areas.
Remember, we can prevent EAB by not

How to Grow and Care for Braeburn Apple Trees Malus x domestica ‘Braeburn’
The best trees for chalk soil conditions tend to be locally grown and not be Dutch imports. In fact they resemble shrubs more than trees but there are the odd exception that are tree like.
A: As much as wild ivy provides a very important habitat for birds and insects, and the arboreal form (the older, shrubby growth which produces flowers), and is a really valuable source of nectar, it can also be problematic in established gardens where it can damage built structures as well as some established, older trees such as your apple tree. With the latter, very heavy ivy growth can eventually cause death by overburdening the tree’s leafy canopy, which in turn can result in (a) broken branches, leading to an increased risk of disease and (b) destabilising of the tree’s root system, increasing the risk of it falling in a storm. Very heavy ivy growth in the canopy of a fruit tree can also reduce the amount of light needed for healthy growth, interfere with blossom set and slow down ripening of the fruit.
If everything you need to complete your dream home improvement project seems more expensive than ever, that’s because it is—and it’s stopping people from paying more money to have those projects done by professionals. Instead, they’re turning to DIY.
Native to Mexico and Central America, the dahlia (Family asteraceae) is a bushy and beautiful flowering perennial. The dahlia is Mexico's national flower, and its tuberous roots were eaten by Aztecs before the Spanish Conquest. Following Central America's colonisation, the dahlia was exported to European nations, where it thrived even in countries with harsh or cold winters. Since the 18th century, botanists, taxonomists and gardeners have held a certain fascination for the flower, identifying over 850 different species each with unique petal or stem structures (this number includes the plant's hybrids, too). Since dahlias are extraordinarily varied in appearance, they also tend to be categorised by the shape of the flower, with 10 categories that include anemone, peony, pompom, ball, decorative, cactus, single and waterlily.
Commonly known as the Winter melon and Chinese watermelon, Ash gourd is native to Japan is found commonly throughout India. When touched, the fruit leaves an ash-like residue on hands. That’s the reason behind its interesting name! Here’s all you need to know about growing Ash gourd!
Did you know that citrus fruits are one of the only fruits in season during the winter? Not too long ago, the joys of taste-testing some unique citrus fruits was limited to winter, but now we can enjoy many citrus fruits (and their many benefits) all year long. One delicious type of orange that you may not be familiar with is the cara cara orange. A relatively new kid on the block, the cara cara is not only beautiful, but it also has a flavor profile that might just make it your new favorite citrus.
No other plant native to South Carolina has such fragrant and beautiful spring blooms and stunning fall color as the witch-alders. Fothergilla was named after Dr. John Fothergill, an English physician and gardener who funded the travels of John Bartram through the Carolinas in the 1700’s. These beautiful shrubs have been planted in both American and English gardens for over 200 years, including gardens of George Washington and Thomas Jefferson.
Are you frustrated because there are dandelions and other weeds in your lawn? Did you know that dandelion flowers provide one of the first springtime sources of pollen for bees, butterflies, and other pollinating insects?
The Asian longhorned beetle (ALB; Anoplophora glabripennis) is not easy to miss – adults of this large, black beetle with white spots, black and white striped antennae, and blueish feet are between 1 and 1 ½” long (Fig. 1). ALB larvae are equally striking as the large, white segmented larvae can be nearly 2” in length (Fig. 2). Established populations in the U.S. are found in Massachusetts, New York, and Ohio, and a new infestation was recently found in Charleston County, South Carolina.
MY GARDENING LIFE STARTED with a hedge—cutting one back hard, specifically. It was the threadbare, tall old privet surrounding my childhood home, and I was determined to “rejuvenate” it, after reading about the process in a book. No artful hedge has ever been created by my hands, though—a fact that feels all the more lamentable after watching Sean Conway’s video tour (above) of designer and nurseryman Piet Oudolf’s garden in the Netherlands. What magic.
