Ash Treatment Recommendations Remain Unchanged

As Emerald Ash Borer continues to spread, we have been saying that over time we may be able to back off some on treatment. The jury is still out on that and conversations with experts such as Dr. Dan Hermes and Joe Boggs of The Ohio State University confirm that not only do we need to keep up the two-year treatment interval with Treeage, but it is unclear when, or even if, we will be able to step down treatment.

At Arbor Doctor, we still believe we will be able to step down at some point. However, we also are committed to following the best recommendation and that is to maintain the 2-year treatment interval.

Just a reminder that we treat after leaves emerge fully. Most treatments should be completed by the end of June.

Spring 2017 Progression Similar To 2016

So, how is spring shaping up? As of March 29, Cincinnati was near 200 growing degree days. A year ago we were around 190 on the same date so we are close to where we were a year ago.

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). A base temperature of 50 degrees Fahrenheit is considered acceptable for all plants and insects.

Using phenology research, we can predict approximate bloom times and pest emergence with a reasonable degree of accuracy. Here is where we were as of this writing:

CINCINNATI – 3/29/2017 199

Compact Garland Spirea – Spirea x arguta full bloom 205

Koreanspice Viburnum – Viburnum carlesii full bloom 205

Azalea Lace Bug – Stephanitis pyrioides egg hatch 206

Spring Snow Crabapple – Malus x spring snow full bloom 209

Viburnum Leaf Beetle – Pyrrhalta viburni first egg hatch 210

Large Crabgrass – first seedling emergence 211

Carolina Silverbell – Halesia tetraptera first bloom 213

Common Floweringquince – Chaenomeles speciosa full bloom 214

Birch Leafminer – Fenusa pusilla adult emergence 215

Coral Burst Crabapple – Malus coralcole first bloom 217

Spring Weather Outlook

Spring is looking very active and stormy. With a very active jet stream, temperatures should be above normal in general, although late frosts remain possible in such a pattern. An active spring weather pattern favors severe weather.

Drought does not look likely in the spring in Cincinnati. Soils are currently wet and an active weather pattern favors additional precipitation chances.

Welcome To Spring Part 2

As we head into April, temperatures are warming up and spring is busting out all over.

What do I mean by Part 2? Well, remember, it got really warm in February and early March, followed by mid-winter cold in mid-March. The February warmth woke everything up and some plants were even blooming in some cases. The March cold stopped that progression and even killed some blooms. We don’t know if there will be any long-term damage, probably not. However, with warmer temperatures returning we are now off and running into spring.

Rainfall has been excessive in some areas. Some soils are waterlogged and this may lend itself to some root disease issues in sensitive plants like taxus and juniper.

Tree Growth Regulators

Growth regulators have many benefits in the landscape:


RTSA-Treated-Leaves-Cambistat (1)Twenty-five years ago, growth regulators were mostly utilized by large utility companies to keep trees out of power lines, but largely ignored by tree health professionals. Today, growth regulators are better understood, widely used, and benefiting trees in ways beyond growth regulation alone, including:

  • Drought Tolerance
  • Greener Leaves
  • Disease Resistance
  • Root Growth

When growth regulators are applied to the root zone of a tree or shrub value can be added by:

  • Extending the time between trimmings, which helps maintain a tree’s size for at least 3 years.
  • Creating healthier trees by increasing root hair growth.
  • Increasing drought tolerance.
  • Redistributing carbohydrates (trees make their own food through photosynthesis) from growth to storage and fine roots.
  • Extending the lifespan of trees by reducing stress from limited root space.
  • Extending the serviceable life of a tree planted too close to a building or utility wires.
  • Correcting mild micronutrient deficiencies.
  • Allows the tree to grow steadily, requiring less pruning and providing added tolerance to certain diseases and insects.

How does is all work?

All trees and shrubs contain a Growth Hormone called Gibberellic Acid or GA for short. GA is principally responsible for cell expansion and to a lesser extent cell division (the process of branch growth). The active ingredient of the growth regulator reduces the effects of GA on the cells. The direct effect is a dramatic reduction in vegetative growth, especially internodal elongation. Which means, the size of treated trees can be effectively regulated by up to 90% for at least 3 years, depending on use conditions. Since many fungi are also affected, treated trees show significantly less effects from a range of plant diseases.

Tree growth regulators are applied by calculating the amount of solution required for the specific tree. The specific amount depends on the type and size of the tree. The mixed solution is then poured as a drench around the base of the tree. The active ingredient is then taken up by the roots and distributed to the tree’s growing points, where vegetative growth reduction can be seen.

The amount of time for root uptake and distributed to the growing points varies according to soil type, soil conditions, time of year and tree species. The growth control is approximately 40-60%, varying by species. Effective growth control generally lasts for about 3 years and then needs to be re-applied.

February Moisture Condition Monitoring Report

Condition Monitoring Report
Station Number: OH-HM-24
Station Name: Cheviot 3.4 W
Report Date: 2/17/2017
Submitted: 2/17/2017 7:20 PM
Scale Bar: Near Normal
Observed conditions are expected for this time of year. February rainfall is below normal with only 0.96 to date and only 0.18 in the last 7 days. Temperatures have been above normal but cool enough to keep soil moisture evaporation to a minimum. Conditions were wet in January and conditions have only recently returned to near normal for this time of year.

What’s wrong with the blue spruce trees in my neighborhood?

Colorado blue spruce trees have long been among the most popular conifers for landscaping in Michigan and the upper Midwest. Blue spruce trees are widely planted due to their good growth rate, stately form and, of course, their blue foliage. Unfortunately, blue spruce trees are subject to a wide range of insect and disease problems that can impact their growth and aesthetic appeal.

The prevalence of diseases on blue spruce trees has intensified in recent years and trees are declining rapidly in many areas… Read the entire article here>>>
