Oak "Apples" and the Gall-Making Process boggs.47 Fri, 05/12/2017 - 13:11
Several types of "oak-apple" galls are now obvious on their namesake oak hosts in southern and central Ohio. These unusual plant growths range in size at maturity from 1/2 - 2" in diameter and are named for their resemblance to apples. The galls are constructed of various plant parts that have been hijacked by a gall wasp (Family Cynipidae) to surround a single wasp larva located within a seed-like structure positioned at the center of the gall.

Recent Cold Temperatures Leaves a Variable Path of Damage to Plants in Ohio

Depending on your geographical location in Ohio, the location of the plant, the actual low temperature, the plant species, as well as the growth stage on the species, the results of frost and freeze damage was variable across the state this past week.  Frost and freeze damage is so interesting because of so many variables.  A plant in a certain stage of growth may be more susceptible to frost or freeze damage than at other times.  The location of the plant in the garden may dictate the extent of the damage.  For instance, there might be two of the exact same plants in the same garden with...

Garden Centers are Stuffed to the Gills!

On recent visits to area gardens centers I noticed that they are filled with inventory and bursting at the seams!  Since we haven't had the best weather for the first part of May, garden center owners are looking for an incredible Mother's Day weekend - the busiest day of the year for them.  The weather so far looks to be promising not only for this weekend but also for next week.  Plants are looking good right now but they need to be moved out the door and into gardens in order to make way for the next crop that is pushing right behind!

 

A reminder to gardeners that once...

Extrafloral Nectaries and ETC boggs.47 Thu, 05/11/2017 - 14:55
Last week, I wrote an Alert describing the "ETC Two-Step Control Method;" a very direct approach to eliminating Eastern Tent Caterpillars (ETC) (Malacosoma americanum). But what about more subtle "behind the scenes" ETC population regulators and where do extrafloral nectaries fit in?

Act Now to Attract Colorful Visitors to your Yard

Each year in late April and early May many colorful migrating birds move through Ohio, often visiting suburban yards.   Some may only stay a few days before pushing on, others linger longer, and if you are lucky, a few may set up shop!   My favorite visitor is the Baltimore oriole, a bright orange and black bird.   Oranges, grape jelly, and nectar are known to attract this species.

Lovely Lilacs Lure Lads and Lassies to the Landscape

Lilacs, the fragrance, the beauty, the grace, the colors. Lilacs can come in all shapes, sizes ans colors. From pale purple to deep purple and white; whether a small, low shrub, a mature shrub to a upright, standard tree form, there is one to fit most landscapes. But even when they can't be seen, the fragrance attracts not only pollinators but people as well.

Doggone Gorgeous Dogwoods!

Here in Northeast Ohio, it has been an incredible year for observing bloom of ornamental flowering trees.  I propose that both the marvelous color and length of bloom is due to the bursts of very warm temperatures (70’s), followed by days of cooler temperatures (50’s), with a day or two of rain mixed in to keep things fresh!  The warm temperatures caused the buds to push fast into full bloom; however, then the cool temps and the rains move in preserving not only the colors, but also prolonging the length of bloom appeal and persistence on the plants.

Sassafras: Tree of the Week

  Sassafras was the bygl-alert Tree of the Week last July 29, but a reprise is in order. First of all, the emerging leaves and flowers have blown me away anew this Spring. Secondly, such a great horticulturist as Deb Knapke e-mailed me that “This is the first time I have seen the flowers of sassafras; loved it!” in response to the use of a sassafras flower picture in one of my Springtime bygl-alerts this year.

Wall of Wisteria

As I was driving along the other day, it was raining and I was watching the road and the plants around me of course, when suddenly, out of the corner of my eye, I saw a flash of purple.  Intrigued, I just had to investigate and find out what the heck was going on with the purple flash!
