There We Go...The Harbinger of Autumn Appears!

As I was driving along the roadways of Geauga County, I suddenly noticed the upright pillars of changing color wrapped around tree trunks.  Yes, I believe that it is most likely, that autumnal color is the ONLY redeeming quality of Toxicodendron radicans, commonly known as Poison Ivy!  At this time of year, the fall colors of this rash inducing woody vine, are unparalleled for their stunning reds, oranges, yellows and every color mixture in-between.  It almost makes one want to go up to collect some leaves to put in a fall color collage between pieces of waxed paper to hang on the...

Tree of the Week: Kentucky Coffeetree

  Kentucky coffeetree is a native tree that is planted as a tough urban survivor in streetscapes, and is tolerant of limey soils and tree pits (Chicago urban foresters list it as one of their five toughest street trees). It has a starkly coarse yet beautiful appearance in the winter landscape, and its fairly early fall defoliation and late spring foliation make it perfect if long seasons of sun penetration are desired.

Trees and Lightning

Recent storms that have moved through northwest Ohio have brought some much needed rain.  Some of that rain has been accompanied by lightning, high winds and even tornados.  The large oak pictured with this article was strike by lightning resulting in the outward symptom a "lightning scar." 

 

As I was searching for additional information when writing this article, I came across a FactSheet from Purdue University, Trees and Lightning.   It is an excellent resource and describes the range of damage to the tree that can occur during and after a lightning strike.  The...

Mushrooms in the Yard: To Eat or Not to Eat has been a Common Question

With the return of more regular rains in some areas of Ohio, mushroom production in lawns seems to be going gang busters.  Some view these mushrooms as a mere nuisance, some are freaked out by their presence, and some want to make a meal out of them.  STOP!  One must have an absolute, positive identification before dining on these "free" mushrooms.

Ode to Joy: A Walk in the Park and German VIllage

  The first image of a caladium and coleus window box above is from a walk I took a few weeks ago with the Ohio Nursery Landscape Association’s Executive Director Frits Risor through German Village and Schiller Park there, and then later in the day checking out the crape myrtles planted in landscapes a little further north near ONLA’s World Headquarters in Westerville. A few other items we saw include:

Cedar Rust Fungi Aecial Tubes Now Evident

  For the last month the fungal tubes of the “aecial” stage of several cedar rust fungi, namely cedar-apple rust (Gymonsporangium juniper-virginianae) and cedar-hawthorn rust (G. globosum) have been evident on leaf undersides of hawthorns, as seen in the accompanying picture.

  These rust fungi spend about a year and half on certain junipers (in the Cupressaceae family) before microscopic spores of the fungus oozing from galls on the juniper blow in the spring to certain genera in the Rosaceae family such as hawthorns and apples and crabapples.
