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

At the end of March, 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 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.

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>>> 

Biochar: A Game-Changer for Soils

By Dave Story in The Landscape Contractor

Everything old is new again. That certainly holds true for biochar, a type of charcoal first produced and used in the Amazon basin centuries ago to make agricultural land more fertile. Biochar results from heating plant waste, or biomass, at high temperatures in little or no oxygen. The process, called pyrolysis, also takes place in naturally occurring fires resulting from lightning strikes. Not only does biochar help soils retain nutrients and moisture, but it remains effective in the soil for hundreds of years – all of which means it can help you better and more efficiently protect the health of your clients’ landscapes. Read more here>>>

Fireblight This Time


From the BYGL…

Fireblight on Callery pear is highlighted against the blue sky in Columbus’s German Village this past Thursday in the lead photo of this byglalert, with a different look in the second photo taken with a different sun angle, important to remember when seeing images and thinking “it doesn’t look quite like what I saw”. Fireblight symptoms of “shepherd’s crook” shoots and discolored leaves are common to see now, following infections which occurred weeks, even months earlier in cool, warm weather during bloom.

Overwintered Bagworm Eggs Have Hatched and Caterpillars Are Feeding

1st Instar Bagworms on Arborvitae

Overwintered common bagworm (Thyridopteryx ephemeraeformis) eggs have hatched in southwest Ohio and 1st instar caterpillars have settled to feed and construct their characteristic sac-like bags.  A percentage of the tiny 1st instar caterpillars produce a strand of silk upon hatching to catch the wind and “balloon” to new locations.  This behavior is one of the reasons bagworms often appear on hosts that were not infested last season.
