Winter burned plants

Friday, March 14th, 2014

This spring we will see things we haven’t seen in a number of years.  Temperatures dropped below zero multiple times this winter.  Many plants in our landscapes are marginally hardy which means they may be killed back or burned in very cold winters.  Expect die back on crepe myrtle, butterfly bush, some azaleas, and possible cherry laurel.  Roots of these plants will be fine.  Also, even hardy southern magnolia will have leaf burn.  While leaves will look bad, new foliage should be fine.  However, remember that southern magnolia doesn’t leaf out until after Memorial Day so be patient when they still look like the last rose of summer in late May.  Many other plants, especially evergreens, may show leaf discoloration, including boxwood and holly.


Tree-saving efforts are taking root

Saturday, February 1st, 2014

Last summer, it was impossible to miss. Visible from almost every road in the Tristate were large areas of dead and declining trees. These trees were ash, and the culprit was the emerald ash borer, an exotic insect accidentally imported into North America to which our native ash have no resistance. Ongoing chemical treatments may preserve a small percentage, but in reality there is nothing that can stop the loss of ash, which for centuries has been an integral part of the American forest. Read more>>>

Christmas is here!

We at Arbor Doctor are so thankful that you, our clients, place your trust in us.  It has been nearly a decade since Arbor Doctor was established.  I have known many of you longer than that.  I consider each of you to be part of my Arbor Doctor extended family and count it as privilege that you place your trust in us.

When I started Arbor Doctor in 2005, we were in the midst of adopting our daughter Melanie from China.  In that process I began praying over our financial situation and within weeks, I lost the job I had at the time…at Christmastime!  What seemed like tragedy at the time was, in fact, an answer to prayer.  God led me to Terry Grear, a CPA and Christian man who helped me to establish the LLC and get Arbor Doctor off the ground.  I knew it was God’s will, but it still scared me to death.

I figure Mary and Joseph were also scared 2,000 years ago when she as a virgin found herself to be with child, the penalty for which in that society was death.  Joseph and Mary remained faithful, against all worldly logic, and the Son of God came into the world.

29 Confused and disturbed, Mary tried to think what the angel could mean. 30 ”Don’t be frightened, Mary,” the angel told her, “for God has decided to bless you! 31 You will become pregnant and have a son, and you are to name him Jesus. 32 He will be very great and will be called the Son of the Most High. And the Lord God will give him the throne of his ancestor David. 33 And he will reign over Israel forever; his Kingdom will never end!”   –Luke 1:29-33 (NLT)

As we progress toward 2014, I cannot promise that I will never error.  In fact, I can guarantee I will. However, I can promise I will seek each day to honor God in all I do, just as I have since Arbor Doctor was founded in 2005, and provide to you the best plant health care service I can.

May God richly bless you and yours at this Christmas season and in the coming new year!

Elliot Abrams’ “Please Pass The Gravy” Thanksgiving Forecast

Saturday, November 23rd, 2013


This was written by Accuweather’s Elliot Abrams several years ago:

Turkeys will finish thawing Thanksgiving morning, then warm in the oven to a high near 190 in the afternoon. The kitchen will turn hot and humid, and if you bother the cook, be ready for a severe squall or a cold shoulder.

During the late afternoon and early evening hours, the cold front of a knife will slice through the turkey and cause it to accumulate 1-2 inches on plates. Mashed potatoes will drift across one side while cranberry sauce creates slippery spots on the other, especially if it mixes in as you turn to the green bean casserole. Please pass the gravy.

A weight watch has been issued for the entire area and we expect intervals of indigestion, with increasing stuffiness around the beltway. During the evening the turkey will diminish and taper off to leftovers and drop to a low of 34 in the refrigerator.

Looking ahead to Friday and Saturday: high pressure to eat sandwiches; flurries of leftovers can be expected both days with a 50% chance of scattered soup during the midday hours. We expect a warming trend baste on where soup develops.

Builders and Flippers

Wednesday, September 4th, 2013

“I do not fear failure, but rather I fear succeeding at something that does not really matter”.

My friend Jim Mullaney, manager of EDOC services which manages the Arbor Doctor office, shared the following perspecive on business building in a recent blog:

If anything was learned from leading a class on entrepreneurship last year it is that business ownership is a complex endeavor. One size does not fit all! Business owners have different styles, dreams, motives and drivers. Some are more “principled” than others. This post is focused on two approaches: Builders and Flippers. At the risk of over simplifying, builders are in for the long haul and flippers are driven by the fastest prize possible.  Read more here>>>

This native Ohio plant has put on a show in the Gateway Learning Gardens in Springfield for about 6 weeks and is still going strong. The yellow daisy-like flowers are on stalks that are around 9 – 10′ tall and sway beautifully in the wind.


Thousand Cankers Disease (TCD) of walnut has been confirmed in Butler County, Ohio

Tuesday, August 13th, 2013

Thousand Cankers Disease (TCD) of walnut has been confirmed in Butler County, Ohio.  The disease is caused by a fungus (Geosmithia sp.) that is carried from tree to tree by the Walnut Twig Beetle (Pityophthorus juglandis); a type of bark beetle.  Here is a quote from the news release from the Ohio Department of Agriculture (ODA):

Walnut Twig Beetle was first confirmed in Ohio in late 2012 in traps set by Ohio Department of Natural Resources Division of Forestry officials in Butler County.  Additionally, scientists from the Ohio Plant Diagnostic Network, a cooperative partnership between ODA and The Ohio State University, recently isolated the TCD fungus from walnut branch samples from the Butler County area, marking the first time TCD has been confirmed in Ohio.”


Keep a sharp eye out for the signs and symptoms of TCD on walnut:  chlorotic and wilted leaves, twig and branch dieback, thinning canopy, and epicormic growth.  Unfortunately, the current leaf chlorosis and leaf drop from walnut anthracnose may confuse the issue.  We will have a report on TCD in this week’s Buckeye Yard and Garden Line (BYGL); the online version ( ) will include images.

Please report suspicious walnut trees to the ODA at 855‐252‐6450 or by email at



Walnut Anthracnose

Tuesday, August 6th, 2013
From the BYGL

Walnut anthracnose disease (caused by the fungus Gnomonia leptostyla) is specific to the genus Juglans including black walnut (Juglans nigra). This anthracnose disease typically results in symptoms late in the growing season which is somewhat unusual for many of the other common anthracnose diseases which are springtime-occurring.
