Proper summer watering of trees

Summer has an intriguing way of luring in longer days, sunnier skies, and vibrant landscapes. For many, summer is a calming retreat after enduring what felt like an endless winter. Naturally, with heat waves we feel inclined to water our trees regularly, but it’s easy to get carried away and over-water.  Read more here>>>

Beneficial rain…for some

Yesterday, CVG had record rainfall of 2.21 inches with over 6 inches for June.  That’s a lot of rain.  However, look at the distribution.

Ohio: Current 1-Day Observed Precipitation Valid at 6/24/2014 1200 UTC - Created 6/25/14 0:16 UTC

This map is a little vague but it will suffice to say that it was a very thin strip and many missed out.  As of this morning I had 1.13 inches at Cheviot 0.9 SSE while Goshen reported 0.68 at midnight and Amelia reported no rain. It is very important to always remember that what matters is what fell in YOUR yard!

 

Ladybugs and other good guys (and gals!)

 

Ladybugs are good guys. Despite their nice name, they are predatory meat eaters and hence they feed on bugs which may harm your gardens. Ladybugs and other beneficial insects are why we prefer low and targeted pesticide use. We want to keep the good guys alive, including the pollinators!!!
“Ladybugs all dressed in red
Strolling through the flowerbed
If I were tiny just like you
I’d creep among the flowers too!”

Your children and nature…

What are the ingredients in your perfect day? A long, hot bath? A walk in the woods? A   drive down country roads with the windows down and the music up?

I find that the things that make my heart sing haven’t changed much since I was a child.   Read more>>>

 

Growing Degree Days (GDD)

GDD is a measure of the daily maximum and minimum temperature and directly relates to growth and development of plants and insects.  The GDD of any zip code location in Ohio is estimated using the GDD of ten OARDC weather stations and available on the

 

Black Knot on Prunus

Numerous landscapers and arborists are noting this year that PLUM BLACK KNOT can be quite a serious disease problem, with reports of high incidence on Canadian red chokecherry (Prunus virginiana ‘Schubert’).

 

Thinking Outside the Boxwoods

The winter damage to Buxus spp. is easy to notice when driving down the road looking at landscapes. Many calls have come into the Extension offices regarding what is the best way to handle these winter damaged boxwoods.

 

Winter burned plants

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

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>>>
