8:00 – 8:30 Growing Quality Trees in the Nursery – Canopy
This is an introduction to modern tree production strategies based on research in the last 15 years. Topics include liner and container selection, planting strategies, and production pruning protocols, and root pruning and field harvesting.

8:30 – 9:00 Growing Quality Trees in the Nursery – Roots –
Trees last for decades or longer when roots grow correctly. We’ll show you how to grow a strong root system in the nursery using the correct liner trays, containers, and field techniques. There are brand new methods to eliminate root defects in containers, and proven field production methods that ensure good roots.

9:00 – 9:45 Planting Trees – New Research Improves Performance
Proper planting includes irrigation, soil management, and root management strategies that reduce transplant shock and improve health on established trees. There’s lots of new information on all this. You’ll go home with new techniques you can use next week.

9:45 – 10:00 Break

10:00 – 10:45 Root Management
Root and soil management strategies hold the key to maintaining and improving health on trees in compacted and other stressful landscape sites. We detail the newest and most effective techniques professionals are using to keep trees growing and customers happy.

10:45 – 12:15 Why We Don’t Want Foreigners
Review the history of introduced/exotic pests in American forests.

AND Florida’s Big Tree Killers

12:15 – 1:00 Lunch – Bring $10.00 for vendor lunch (salad, meat, veggie, starch, rolls, dessert and tea), or bring your own.

1:00 – 2:00 Pruning Trees In The Early Years
New developments in tree biology and recent advancements in the science of tree structure provide a sound basis for delivering efficient preventive pruning treatments. We present preventive arboricultural strategies now known to increase tree health and longevity

2:00 – 2:45 Pruning Mature Trees
You will go home with a new understanding of how and why we prune mature trees, and how to apply it to most real life situations. We will decipher thinning, reduction, raising and structural pruning.

2:45 – 3:00 Break

3:00 – 3:45 Structural Pruning – New Research
Pruning can have a dramatic impact on how trees respond to gravity and wind storms. Our data generated from a wind machine producing up to 120 mph winds shows that structural pruning designed to reduce growth rate and weight on co-dominant limbs is the most effective method of minimizing damage from storms.

3:45 – 4:30 Designing Urban Spaces for Sustainable Tree Growth
Learn how to design spaces including sidewalks and parking lots to support tree growth so your design vision can be fulfilled. There will be lots of photographs, illustrations, specifications, and take-home messages involving the audience.

A very good guide to beginning gardeners and arborists. One thing I can't stress enough when teaching about gardening is your placement. Look for whats above, behind, below, and what it could grow to block or overcome. Happy Gardening!

Recycling helps the earth because it could save animals, it could save birds, puppies and all kinds of them. A lot of the animals that recycling helps to save are the ocean animals. There are a lot of animals in the ocean that mistake trash for food. They're eating things that we could be recycling. Check out this video:

Nice post. For having proper air in your home you got to be right with your ventilation works.

Have you read Teaming with Microbes? Good book that is doing a lot to help me understand the good side of fungus and all the other tiny stuff in the soil. Who knew?

I saw several nymphs this season for the first time ever. They are some of the more bizarre bugs to have in the garden, but I hope they'll have a good effect!

We have the dog vomit slime mold for the first time in our yard as of this spring.

Thank you for this post, it is reassuring to see that what we are doing (organics ONLY) are making a difference!

Thanks Theresa, there was a host of the Slender Flattop Goldenrod, Euthamia Caroliniana, last Oct. in an open field now just knowing this species, and what I think is the Late flowering Thoroughwort, Eupatorium serotinum nearby in semishade making the bees crazy.

We have ongoing problems w/ this @ the city park where I work - I've tried rinsing the affected skin w/ hot water, which seems to help. I understand that cooking neutralizes the sting (people actually make tea from & even eat stinging nettle).

What a cool looking mushroom. I think I will take the writer's advice and avoid walking in the dark woods to find it though.

I love both the beauty berry and firebush together. Always have flowers or berries, bright colors, drought tolerant to a degree... Nice plants!

I really like the pic of winter flowers. Your article is very well written cant wait to read more. Interesting Blog I really liked it.

Has there been any discussion as to why the population explosion of the spanworms occurred this year? Was it related to the very dry winter and spring (eliminating many wasps) followed by heavy rains which spurred the snowbush's growth?

Great links! Thanks for sharing!

Great tips. I recommend that all DIYers mow tall in summer just to avoid additional pressure on struggling turf.
Organic fertilizers work well in summer to avoid excessive growth, as long as they have plenty of time to break down prior to those heavy storms you mention.

July 21, 2009

That was an important point you made about fertilizer use during this rainy time. Suggest all use slow-release fertilizers to avoid excess run-off of nitrogen & phosphorus into our waterways.

The lawn looks very poor.

Thanks for such great details. For the 37th Edition of the Festival of the Trees blog carnival, we talked about Survivor Trees. Your post was a fitting addition to the "Hurricane" section!

I got to this page from reading your article about laurel oaks. I would love to chat with you about a problem that I am having with one of the oaks on my property- either by phone, or email. If you could oblige me, I'll send you my email address.

Now, back to reading about these orchids!

I am fully behind the termination of Sevin use for anything that might come in contact with any beneficial life forms.

I briefly read this early this month and discarded it, but while in downtown ST Augustine I saw a palm with symptoms that could be a diseased palm. This was the other day in the plaza (used to be called the slave market). That would be a big jump from Manatee / Hillsborough County, but other palms around this specimen in the area are healthy and it has been in the ground for some time. It probibly is anouther disease or deficiency. I have been in the nursery/ landscape business for 30 years and hate to see the infections that are effecting our major trees, citrus, bays, palms, next? Craig Hartwig.
