Record Warmth On Tuesday, Accelerated Growing Degree Day Accumulation

Growing Degree Days are a measurement of the growth and development of plants and insects during the growing season. Development does not occur at this time unless the temperature is above a minimum threshold value (base temperature). The base temperature varies for different organisms. It is determined through research and experimentation. The actual temperature experienced by an organism is influenced by several factors. These factors affect growth and development. For instance, depending on the weather, an organism’s temperature may be a few degrees more or less than that recorded. An organism may spend its time in the shade or under direct sunlight. The fertility and nutrient content of the soil directly affect the growth rate of insects and plants. The presence of weeds and precipitation may indirectly influence development. Due to these factors and some other scientific considerations, a base temperature of 50 degrees Fahrenheit is considered acceptable for all plants and insects.

Record Warmth and Flooding Rains

Flooding is already widespread in the Ohio valley and soils are saturated. In the coming days, tremendous rainfall amounts are likely on top of already saturated soils. Considerably more flooding is likely and some areas, especially southwest of Cincinnati, could see historic flooding. Over 4 inches of rain is projected in Cincinnati over the next 5 days.

Additionally, Tuesday was exceptionally warm in the Ohio valley, threatening to send plants surging into spring mode much too early. The temperature at Cincinnati reached 79 degrees F. That breaks the all time record high temperature for the entire month of February of 78 degrees set just last year  in 2017.

Flooding Rains and Accelerating Spring

A strong southwest to northeast flow of warm, moist air between a very warm southeast US high pressure ridge and a western US trough will efficiently guide round after round of moisture up the Mississippi and Ohio River valleys.  The Ohio River is already forecast to go well over flood stage and continued heavy rainfall will only exacerbate the flooding. We are likely entering a period of significant, long term flooding and accelerated spring warm up and green up. In addition to the heavy rain and flooding, growing degree accumulation will accelerate and an early spring will accelerate.

Woodpecker Tree Damage: Preventing And Repairing Woodpecker Damage

By Heather Rhoades
Woodpecker damage to trees can be a serious problem. Woodpecker tree damage can cause trees to become diseased or even to die. Because of this it is important to stop woodpecker damage before it hurts or kills beloved trees in your yard. Keep reading to learn more about how to prevent woodpecker damage and the steps for repairing woodpecker damage once it has happened.


Creation Care and Environmental Stewardship

Genesis provokes more questions, debates, and doubts than any book in the Bible. To really understand the story, we have to step back from our preconceived notions and read it through the lens of the original audience. At its heart, Genesis is about a God who makes gardens out of chaos and calls us to do the same. Understanding Genesis will help us understand the rest of the Bible.

What is coppicing?

On Saturday morning’s In The Garden With Ron Wilson show a caller asked about the Norwegian practice of coppicing. Neither Ron Wilson nor I were familiar with the term but that’s how you learn! Here’s a great article I found from the United Kingdonm.

Coppicing is an ancient form of woodland management that involves repetitive felling on the same stump, near to ground level, and allowing the shoots to regrow from that main stump. (Also known as the coppice stool).

Emerald Ash Borer: A Few Survivors Among the Devastation

It is getting more and more difficult to find a live ash tree in Cincinnati. A vast majority of ash trees in Cincinnati and the surrounding area have been infested and killed. Treated trees remain alive and treatments have proven quite effective.

Research is being done in infested areas to determine if treatment frequency can successfully be reduced. So far that research is not promising and the every two year recommendation remains for Treeage insecticide, and annual treatment is recommended for other insecticides.

Despite the extent of ash devastation, we occasionally find ash trees seemingly thriving without treatment. To be sure, these trees are rare but they have been reported throughout infested areas. A few of these trees have even been found by me!

What are we to make of this? So far, no foundation for the immunity or resistance has been identified by researchers. Efforts are underway to catalogue and study these trees to try to find a common thread, perhaps even to turn the tide. However, these efforts are just beginning and no conclusions have been drawn. The chances that any one ash will survive without treatment are very small.

At Arbor Doctor, we keep up to date on research and we will certainly incorporate any changes in treatment protocol into what we do. For now, no change is recommended.


3 Things You Can Do with a Tree Growth Regulator Besides Regulate Growth

Red Maple Leaves

On a hot day in late summer, an observant city forester noticed something different between two groups of linden trees planted along opposite sides of the street. The lindens growing along one side were showing the typical symptoms of late-season drought: yellowish-green colored leaves, scorched edges, and an overall wilt-y appearance.

What’s in YOUR honey? It may not be the nectar you expected.

This month’s National Geographic has a brief article from an ongoing study of the DNA profiles of urban honey. While we can all observe honeybees visiting flowers in our own gardens, until recently we could only assume what nectar they were collecting for honey production. This tantalizing snippet completely blew me away.
