Maryland Counties Quarantined for Emerald Ash Borer

Since the presence of the emerald ash borer, a highly invasive tree pest, has been confirmed in Howard County The Maryland Department of Agriculture (MDA) has created a quarantine area in Charles (detected 2008), Howard (detected June 2011), and Prince George’s (detected 2003) Counties.

The quarantine prohibits anyone from moving ash trees or any hardwood firewood out of the three counties until further notice to hamper the spreading of the EAB (Emerald Ash Borer). As it is still early in the EAB season they will be surveying the area to assess the infestation and keep the quarantine updated.

There are around 6,000,000 ash trees in Maryland. The USDA has estimated that losses could exceed $227.5 million in the Baltimore area alone if the emerald ash borer were to get a foothold.

Emerald Ash Borers kill ash trees within 3 years of infestation. Signs of infestation are:

  • Upper third of tree thins and dies back
  • A flourish of shoots or branches coming out the infected portion of the tree
  • Small D-shaped exit holes in the bark
  • Vertical splits in the bark
  • Looping tunnels beneath the bark in the cambium, where larvae stop food and water movement in the tree and starve it to death.

Don’t move firewood, don’t plant ash trees, and call Wood Acres Tree Specialists should you suspect the vociferous Emerald Ash Borer (look for a metallic green insect). Visit our insect index for image and more information on EAB.

Temperature’s Role in Tree Growth and Insect Populations

Temperature's Role in Tree & Insect Development

Trees’ and insects’ growth and development are dependent on environmental factors like temperature (heat), light and humidity.  Because insects are cold-blooded, temperature has the greatest effect on insect development rates.Development rate increases as temperature increases up to a point.  In the temperature range from 10 to 30 degrees, development rate changes almost linearly with increasing temperature.  At very low temperature there is no development, and at very high temperature development is stunted.

 

Since temperature influences tree growth in a similar manner to insects, development of the various growth stages in the tree is dependent on temperature.  Each stage of tree development requires a certain amount of heat units before growth to the next stage will occur.  This measure of accumulated heat over time is known as physiological time. For instance, remember the cool, rainy late-winter/early-spring weather we recently had? This year’s cherry blossom’s in DC went from 2/28/2011 (green color in buds) to 3/29/2011 (peak bloom).Last year’s cherry blossoms only went from 3/14/2010 (green color in buds) to 3/31/2010 (peak bloom) because it was warmer earlier – so developmental growth speeded up – and left us with less time to enjoy the blooms.

For many years, growers have observed the arrival or development of a partlcular insect pest with flower bud or leaf development and have timed the applications of sprays in the spring.  This is an indirect use of physiological time.  Using these natural timers are most useful early in the growing season when tree growth stages are readily observable. However, making accurate predictions on insect life stages throughout the growing season are needed.  This is done by measuring degree-days of the insects in question.

What are degree days? Entomologists have determined lower threshold temperatures and degree-day totals for the life stages of many  insects by studying their development in the field and the laboratory.  The lower developmental threshold for a species is the temperature below which development stops. The upper developmental threshold is the temperature at which the rate of growth or development begins to decrease. Phenology models are then developed and used to predict various events or lifestages of an insect. This is useful for tree and shrub care companies because it gives a general timetable for when to treat insect pests during the correct stages to be effective.

Mother Nature is full of surprises! If you find your insect pest populations are out of control this season and damaging your trees and shrubs, contact Wood Acres Tree Specialists for a consultation. It takes years to grow a beautiful tree or shrub specimen – don’t let it be disfigured or destroyed in one season.

Tent Caterpillar or Gypsy Moth?

Eastern Tent Caterpillars

Eastern tent caterpillars and gypsy moth caterpillars- both are about the same size, hairy, and have bands of black and brown colors with narrow yellow stripes, and blue spots. But -Gypsy moth caterpillars also have red spots and this is a distinct difference between the two.
Gypsy moth caterpillars are not just an unattractive nuisance, but this invasive pest is very harmful to deciduous hardwood trees, like oak. The damage they can do to trees ranges from light to nearly full defoliation. Entire parks have been closed for spraying to try to control their ravenous appetites. Most infected trees will survive a single infestation and defoliation, but continuing damage can weaken a tree and leave it vulnerable to drought, cold, disease or other insects.

The other major difference is in their eating habits: tent caterpillars prefer to feed safely in their tent. Gypsy moths don’t make webbing and eat out in the open.They like to hide on the underside of leaves, branches, or some other inconspicuous part of the tree, or they hide in brush on the ground, and do most of their main feeding in the veil of night so predators don’t pick them off.
Eastern tent caterpillars damage occurs early in the season and their host trees can usually grow more leaves afterwards and rebound.
If you believe you have a serious problem with caterpillars contact Wood Acres Tree Specialists for a consultation with our tree and shrub care division.

Spring Planting: What trees will do well in my yard? 

Trees for the Maryland Area

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Spring is a popular time to plant trees. But many homeowners in Maryland and Washington, DC choose a tree for beauty and don’t consider other property or site considerations.

Ask yourself these questions:

  • Do I want shade? Will I require extra security lighting? Will it effect my neighbor’s landscape?
  • How much light is available for the tree?
  • Do I want to attract wildlife?
  • Will it increase my property value?
  • What’s the mature height and spread? Is there enough space to plant this tree?
  • Is color a main factor? What are the ornamental effects? Fruit, flowers, bark, color in Fall?
  • Is the tree hardy in our area? Can it take our hot summers and cold winters?
  • Is my particular yard’s environment right? Soil pH, drainage, utility locations above and below the ground (don’t plant trees over 25′ under utility lines – there should be 10′ clearance to reduce electrical hazards).
  • Does my community or municipality have any restrictions as to planting?
  • Will there be a lot of maintenance with the tree species? Leaves in Fall, pruning, susceptibility to storms, disease, insects?

If you require professional analysis of your trees and lot contact Wood Acres‘ arborists to make sure your new trees have a long, healthy life and you get the most enjoyment from your choice. We offer full-maintenance tree and shrub programs to keep them thriving year after year.

Below is a list recommended trees by the State of Maryland that do well in our area:

Tree & Forest Pests – The Invisible Alien Invaders

Before you know it your beautiful century-old tree that defined your entire property could be gone. How could it happen right under your nose?:  Invasive species. The nation’s forests and trees are at risk from these silent invaders from “out of town”. These tiny bugs cost the US economy $120 billion annually.

Invasive species are bugs, borers, and beetles that come into the U.S. by way of package, shipping materials, plane, vegetable, flower – or any other carrier that passes from one country to another. They enter, too tiny or deeply burrowed to notice, find a species of tree that they like, flourish, establish a population – and have no natural predators. They are almost impossible to eradicate once they’ve reached that level.

Some insects that are on the invasive species list currently:

Preventing Snow Damage to Multi-Leader Trees & Shrubs

Winter Weight on Trees and Shrub

With the cold, snowy weather upon us in Maryland and Washington, DC, Wood Acres starts receiving calls from customers concerned about splitting or fallen trees. (Memories of the 2010 Snowmageddon are still fresh) Some species are definitely more susceptible to the added weight of ice and snow more than others.

Previously we discussed the white pine problem – fast-growing trees favored by unknowing homeowners who want quick shade but instead end up with a brittle monster prone to breakage in storms. The white pine often develops weak, v-shaped crotches that easily split apart under heavy participation and high winds.

Besides avoiding fast-growers in the landscape you take care with multiple leader trees and conifers. Multiple leader, upright evergreens, like arborvitae and juniper, and multiple leader or clump trees, such as birch, are most subject to snow and ice damage. Smaller trees need to be wrapped and larger trees with wide-spreading leaders should be cabled.

TIP: You can secure your smaller multiple leader trees with strips of carpet, strong cloth or nylon stockings two-thirds of the way above the weak crotches. You can also connect large Bungee Cords (elastic ropes with hooks on either end) at the hardware (make sure it’s supportive but not too tight). Remove the wrappings during spring to avoid binding new growth and girdling limbs and trunk.

Wood Acres Tree Specialists  provide professional cabling/bracing services to protect your trees and shrubs. To have a healthy, intact landscape next Spring make sure to contact our certified arborists before your weak tree or bush becomes permanently damaged or downed in a winter storm.

Invasion of the Brown Marmorated Stink Bug

Brown Marmorated Stink Bug

Discovered in Allentown, PA in 1996, this insect has now made its home in over 25 States. It was quite prevalent early this spring, and then the unusually dry, hot weather must have helped propel it straight up the charts to #1 on our 2010 INSECT chart.

Reddish brown-black nymphs hatch from light-green eggs laid on either upper or lower leaf surfaces. After 5 nymphal stages, they become long shield-shaped brown adults with white markings on the hind end. If you want to see the adults just look around your house. They are sneaking in for the winter.
Pesticides don’t really work and wouldn’t last more than a few days to a week. Homeowners should concentrate on caulking and replacing screens to seal up those entranceways (good for saving energy, too) – as they enter through any crack they can find. Or, just get used to these relatively harmless insects – they don’t bite. It is true that when you crush a stink bug, they release a pheremone (that some say smells like stinky feet) that attracts even more stink bugs. It is better to help them find their way back outdoors without squeezing them and getting more pheremone in the air.
This year, “Cat-Facing” feeding damage from its sucking mouthparts has been noted on fruit trees and vegetable crops, affecting crop quality. Feeding on hundreds of hosts- the actual amount of damage caused by this feeding varies and the long-term effects of feeding on things like tree trunks is not well known.
So if you see a “Stink Bug”, don’t squash it or you’ll unfortunately find out how it got it’s name. Read more about it in our insect database at Wood Acres Tree Specialists.

Regular Pruning Saves Trees – & Money.

Wood Acres Tree Specialists recently received information from Wayne Knoll, City Forester of Rockville, MD.  He was discussing the recent severe storms that had downed so many deciduous trees in his area of management and made an interesting observation:

According to Mr. Knoll,Rockville has approximately 28,000 street trees on 160 miles of street. His current budget allows for pruning all streets on about a 12-year cycle. During the February storm events, his office received approximately 200 reports of tree or limb failures. (Many of these failures were associated with evergreen trees, mostly white pine, in parks and on landscaped berms adjacent to major roadways. Since evergreens are more prone to failure due to excessive snowfall whether or not they have been recently pruned, he excluded these from his data). All trees listed below are deciduous street trees of various species and size. The majority of the failures were on maple species.

Of the 200+ tree related calls we received, 114 were for deciduous trees located in the City right-of-way along neighborhood streets. The vast majority of these were for partial tree failure with only a few whole tree failures.
  • Street trees that received routine maintenance pruning within the past five years incurred 19 of the known failures.
  • Street trees that have not received routine maintenance pruning for at least 6 years incurred 95 of the known failures.
Thus, 84% of the reported damage occurred on trees that have not received routine maintenance pruning for six or more years.

So, if you would like to significantly reduce your property’s tree failures during storm events, thus saving time, money and reducing liability  talk to us about regular maintenance for your trees – and keep them beautiful longer.

Identifying Bagworms

Credits (left to right) Lacy L. Hyche, Auburn University, Bugwood.org John H. Ghent, USDA Forest Service, Bugwood.org Terry Price, Georgia Forestry Commission, Bugwood.org

What is my shrub dying and what are those “pinecone” things hanging from the branches? We hear that a lot in this area, especially in this extreme heat when your trees are already in a stressed state.

If you do see bags made out of needles or leaves on a woody plant that is defoliated the chances are you have bagworms. Bagworm caterpillars make distinctive 1.5 to 2 inch long spindle-shaped bags that can be seen hanging from twigs of a variety of trees and shrubs.

Bagworms prefer juniper, arborvitae, spruce, pine, and cedar but also attack deciduous trees. Female moths cannot fly but the larvae can disperse. Very small caterpillars can spin strands of silk and be carried by wind, an activity called “ballooning”. Larger larvae may crawl to adjacent plants.
Bagworms pass the winter as eggs (300 or more) inside bags that served as cocoons for last year’s females. The eggs hatch and the tiny larvae crawl out to feed. Each uses silk and bits of plant material to make a small bag that protects and camouflages it as during feeding and growth.
Bagworm caterpillars feed for about six weeks, enlarging the bag as they grow and withdrawing into it when disturbed. Older larvae strip evergreens of their needles and devour whole leaves of susceptible deciduous species leaving only the larger veins. When abundant, the caterpillars can defoliate plants.
Heavy infestations over several consecutive years, especially when coupled with other stresses, can lead to plant death.
Should you see these telltale bags hanging on your trees or shrubs, please call Wood Acres Tree Specialists to assess and treat the damage before the stressed plant can’t recover  -or its natural form and beauty is ruined for years.
