The City of Jefferson, Georgia recently hosted a Community Forestry Roundtable for neighboring tree board members and city and county staff to discuss stormwater management issues and gain a better understanding of how trees contribute to stormwater management and water quality. The Roundtable was facilitated by consulting forester, Connie Head, and funded by a grant from the Urban and Community Forestry Assistance Program of the Georgia Forestry Commission.
About fifty people from fourteen different cities and counties attended and showed great interest in the subject. Linear bio retention, infiltration basins for streets and plazas and porous paving materials were discussed as solutions for better stormwater management. Oxford College of Emory University has incorporated these practices into the landscape design features in place at their new Residence Hall Complex, East Village.
Many issues came up in the discussion such as maintenance and tree removal on retention ponds, aeshetics, site access and more, but the general consensus was that we need to look at stormwater in a different way, cherish it as a resource and not think of it as runoff. Since the pace of growth and development has slowed some, right now might be a good time to evaluate your engineering systems and tree canopy. Can older basins be re-engineered? Are you building in a flood plain? What are some incentives for homeowners to plant and maintain trees, such as stormwater credits?
Post your thoughts, comments and case studies and thanks to the City of Jefferson for recently engaging Georgia's communities in this discussion of trees and stormwater treatment.
If outdoor watering is permitted in your area, trees should be watered thoroughly underneath their drip lines, the area below the tree’s canopy, where rainfall drips from the foliage to the ground and onto “feeder roots.” When this area is saturated weekly, these vital roots are able to continue nourishing the tree and preventing moisture stress during dry periods. Thorough watering once a week, or once every other week, is more beneficial than light, irregular watering.
Tips on tree water:
Water conservation can be accomplished by getting extra mileage out of used water. Certain types of waste water can safely be used to sustain your trees. Water from dish or clothes washing works well because it is diluted.
Trees also benefit from mulching because it helps hold moisture in the soil. This can be especially beneficial in shallow-rooted species, such as dogwood.
Trees should not be fertilized in a drought because it stimulates growth in branches and twigs and puts extra strain on the trees’ limited water supply. As cooler weather approaches, trees will require less moisture and supplemental water isn’t necessary.

The Atlanta Beltline Arboretum is an amazing endeavor for this city and such a great opportunity. Look at this link to learn more: http://www.beltline.org/Implementation/AtlantaBeltLineArboretum/tabid/2932/Default.aspx
We hope by watching these videos that it will spark more questions and allow us to provide more answers to our clients. Our first video post is on why its important to prune your planting stock at the time of planting and demonstrates the problems associated with not pruning your trees when they are planted and tree tubes are installed. Even if you are not installing tree shelters, these problems will exist for those trees left out on their own.
We have chosen to make this our first video as most people have already planted their trees for the year and so its too late to prune at the time of planting all those crabapples, persimmons, walnuts, apple trees and other hardwood species. In case you didn't prune or thought why take the time, take a moment to see how 30 seconds can change the life of your tree and how that small amount of time will create a healthier and larger tree faster!!!
We all know trees will grow themselves, but why wait??
Thanks for Watching,
Many states across the Southeast have water stewardship laws in place – or will in the future. What does this mean for those of us that feed our plants like we do a fat cat? It’s diet time for your watering habits.
For the sake of the planet, here are a few tips on how to water your thirsty greens efficiently.
Water at the roots, not the foliage. You save water and lessen the chance of disease.
Water at night to reduce losing water to evaporation.
When you water, water deep. Watering lightly and frequently causes roots to grow closer to the surface, which in turn makes them require more water.
If you have a sprinkler system, consider investing in newer equipment, for example rain and soil moisture sensors or simply more efficient sprinkler heads and rotors.

You plant, you water, you fertilize and you cherish them. And what do you get in return? Most of us know the general perks: Clean air, shade, reduced soil erosion and of course, natural beauty. But did you know that trees and other plants are nature’s state-of-the-art water filters, purifiers and even coolers?
Here’s a list of all the ways trees are keeping your rivers, lakes and streams clean and fresh this summer:
Preventing thermal pollution (the heating of water runoff) through water absorption and shade. This protects aquatic environments and keeps them cool and refreshing in the summer heat. Did you know that an unshaded stream can get up to 20 degrees warmer than a shaded stream?
Capturing pesticides, sediment and other runoff before they are swept away into nearby waterways.
Intercepting up to 12 percent of rainfall, slowing entry into the stormwater system and allowing more time for the water to be naturally absorbed and filtered so that stormwater systems are not overwhelmed
Protecting shorelines with a series of deep root systems. We like going to the river, but we’d prefer the river not come to us.
Recycling fresh water into the air, which ultimately results in those welcomed afternoon showers that break the summer heat.

More cement and asphalt paths are being created through woods in parks as alternative transportation corridors and to view nature. Typically the paths are placed adjacent to mature trees. The damage often shows well after the contractors have left the scene. The cement compresses and damages roots and can prevent water absorption but the most damage occurs during installation when the ground is graded and roots are dug up and/or compressed. The first choice would be to build such a trail outside the critical root zone, however, often this is not an option. I have seen two solutions to the problem. One was to literally bridge the roots with a boarded walkway, piers, anchors, and/or bridge. A promising and less expensive technique called “root bridging” uses expanded slate and geo-textile fabric to prevent soil compaction. The path is then laid on top of slate and fabric. While root bridging is not ideal for the roots under the "bridge", it does provide an opportunity for the roots to move to an area of less compression. This method was recently used in the Atlanta Botanical Gardens path through Storza woods. I have heard claims of cost reductions due to less soil having to be moved around. More importantly who wants a path with a bunch of dead or dying trees along it!
Municipalities often wonder how big their street trees will become and if they will create damage to surrounding infrastructure, however New Orleans seems to have different ethic, let them grow! As a result they have one of the most amazing urban forest in the country. We know the the issues surrounding an uneven sidewalk, but have we considered the advantages? Perhaps with an expectation of uneveness, there would be more awareness and less accidents. Humans did not evolve walking on flat surfaces. Anyway, below is a picture of street tree that has exceeded all expectations, one example of thousands in New Orleans.
As the world gets smaller through global commerce and international travel, disease and pests also find themselves migrating from region to region, country to country and continent to continent.
Since insects fly, crawl and generally move about, they are easier to spot than signs of disease or other abiotic impact (i.e., pollution, poor soil conditions, improper care). Some inserts are dangerous to trees because they eat bark, flowers and leaves, bore into the wood and cause other problems.
However, running to your local hardware store for a bottle of insecticide is not the healthiest solution for your trees. Killing all insects rids your tree of the bugs that can protect it – leaving your tree open to further infestations.
In addition to insect infestation, disease can rapidly attack and destroy a healthy tree and can spread to other trees through root systems, infected soil, the air, insects and other channels. Diseases need certain conditions to infect a tree: a willing or susceptible host, favorable conditions and perfect timing.
To protect your trees, follow the steps below.
Plant hearty trees and cultivars generally resistant to disease
Add compost to the root zone and use fertilizer to strengthen trees against disease and insects
Prune and rake regularly to help prevent against insects that bore down into twigs and lay eggs; regularly checking for and removing infected twigs and raking fallen limbs and twigs during early spring removes hidden egg nests
Hard, steady streams of water remove and/or kill bugs that may be infesting your tree
Create your own insect traps; slugs are attracted to beer, aphids to soapy water and white flies and cucumber beetles to yellow, so place shallow dishes of beer or soapy water near the tree, or coat a yellow object with something oily and sticky

Our furry friends sometimes like to snack on unusual things, including the plants in our gardens. However, some of these plants can be dangerous to cats and dogs – even in small amounts. To keep your pets safe, try the following steps:
Read labels on plants and shrubs before you purchase them to make sure they are safe for your cat or dog
Watch your pets when they are rooting around in the garden and take note of what they are drawn to
Keep pets away from areas recently sprayed with pesticides
Store fertilizers and poisons out of reach of pets
On the other hand, sometimes you need to protect your garden from the neighbor’s beagle who likes to dig up your tulips. To keep your garden safe from nosey cats and dogs, try the following:
Place cement blocks or chicken wire from the bottom of the fence to a few feet below ground to keep out (or in) dogs that burrow
Trim limbs and branches that hang over the fence to keep cats out (or in) your yard
Create a fenced yard within your yard to separate the garden from the dog run
Use raised planting beds for berries, veggies and ornamental plants
Surround young trees in wire enclosures to protect them as they grow
