Amborsia Beetle Scouting

Scouting for Ambrosia Beetles

Landscapes and Nurserymen alike should consider putting out traps now and monitoring for Granulated Ambrosia Beetles.  One of the primary indicator plants for the emergence of these insect pests is the flowering of Saucer Magnolia.   With the warm spring-like weather we have been having
the Saucer Magnolias have began to pop out in full bloom.   I have seen them beginning to flower in parts of Transylvania and Henderson County and they are likely beginning to show color in other parts of WNC. 
Please visit the following link to see how to make a simple trap as well as get information regarding pesticide applications:

Invasive Grass of Concern

Cogongrass

The folk at the NC Department of Agriculture and Consumer Services asked us to spread the word about this noxious weed. The weed scientists at NCDA&CS are very concerned about Cogongrass entering our mountain ecosystem.

http://www.ncagr.gov/PLANTINDUSTRY/Plant/weed/Cogongrass.htm

If you suspect that you have found an infestation please contact the NCDA Weed Specialist Bridget Lassiter at (919) 707-3749.

This is an interesting grass as one form was sold as an ornamental grass back in the early '90s under the name Japanese Bloodgrass  Imperata cylindrica " Red Baron".   Some of you may have been misinformed as I was,  and used it in landscapes or sold it in your garden centers, with the impression that it was a sterile form of the species.  I seem to recall that it did not appear to overwinter very well here in the mountains- but then some of those winters were colder than we have experienced lately.   Unfortunately,  in some climatic conditions it becomes a noxious weed.  

For more information contact your local Cooperative Extension Center and ask for the Commercial Horticulture Agent.

Fire Ants Expanding their Territory

Fire Ants are Expanding their Territory 

Fire Ants are expanding their territory in NC and additional counties or portions of counties are now under quarantine.  Essentially, for the green industry this means that certain products (nursery crops, pine needles, hay, straw, etc) can't be move out of those counties without being properly treated.  For more information read the link attached above. 

For more information contact your local Cooperative Extension Center and ask for the Commercial Horticulture Agent.

Cicadas are Impacting Trees in WNC

Cicadas are Impacting Trees in WNC

If you or your clients are noticing dead twigs on forest or landscape trees, chances are that it is the result of Periodical Cicadas.  The female gender of these insects cuts slits in the twigs of various species of trees and lays her eggs.  The result is the death of these twigs which turn brown and ultimately fall off of the tree.  As this has already occurred there's little that you can do to prevent of control the problem, however pruning out the damaged twigs and destroying them may reduce the population for future outbreaks.  Check out the attached article on Periodical Cicadas:

Post Drought Stress Symptoms

Post Drought Stress Symptoms

Although we are getting what appears to be adequate rainfall now, we are still seeing symptoms of drought stress or "post drought stress".    These symptoms may vary from wilting and slow growth to smaller than normal leaves and entire canopy death.   While some of these symptoms may have occurred last summer and into the fall there seems to be a continued showing of cracked trunks and branches with die back occurring on trees and shrubs now even though we are getting good rainfall.

Most of these problems relate back to a failure to water the plants adequately through an entire establishment period.  Trees, particularly those that are field grown and sold balled and burlapped are particularly susceptible due to the amount of root loss that they encountered when harvested.  Typically, a tree takes one year per caliper inch to get re-established so a 2 inch caliper tree will take 2 years of careful monitoring and extra care to see that the root ball doesn't dry out to reduce the potential for drought stress.  Some plants, such as Leyland Cypress and many flood plain species are drought sensitive and may require extra care to keep them from drying out.   Here are a couple of samples from a Sweetgum tree that was planted just before the drought of 2016 and is showing drought stress this spring:

   Note the cracking in the main trunk!↘
