Oh, Christmas Tree....




Oh, Christmas Tree….


 
A fresh cut or live Christmas tree can add so much to your holiday décor, making the whole house fragrant with the aroma of Christmas past.  Scientists tell us that scent is tied in closely to our most precious memories.  There is a reason that every year the commercial aromatic industry provides us with a pine/balsam/spruce scent for holiday spritzing.  Sure, you can use a “can-o-pine” air freshener to try and replicate fresh evergreens, but it is not the same. 
Christmas tree farms are totally “green”!  They are what sustainable agriculture is all about, replanting after harvest and conscious of both soil and water conservation. Artificial trees are made of metal and/or plastic, take up valuable space and are not recyclable.  With the holiday season starting tomorrow, many folks are thinking about their tree of choice. So consider a live (balled and bur- lapped with live roots) or fresh cut tree this year! 
Selecting a tree is more about personal preference than anything. Size, availability, and budget are the next concern. Just remember trees are like other living things and vary individually.  Once you decide on the type of tree you want (such as pine vs spruce), look for the best choice for the area in your yard you wish to plant it.  Remember that a living tree should stay indoors for only a week at the most.   Deborah Hill from the Kentucky Department of Forestry says “When a living tree has been enjoyed in the house for a week return the tree to a sheltered, but un-heated, location as you did before it went into the house. With all the decorations removed, mist the needles down again and make sure the root-ball is still damp. After two or three days, plant the tree, remembering to remove all plastic twine, wire, and burlap from the root-ball. Slightly loosen the soil of the root-ball and use the protected, reserved soil from the hole to fill in around the tree. If temperatures allow, water the tree thoroughly after planting and put mulch (wood chips, sawdust) 2 or 3 inches deep around the tree (but not touching the bark of the tree). If there are warm spells during the winter, water the tree again, but otherwise it should just begin growing new needles in the spring.”

A cut-it-yourself tree farm is the freshest place to find your holiday tree, but for many of us that is not an option.  Pre-cut trees are readily available and the selection is usually great!  Keep a few things in mind when selecting a pre-cut tree:
*No falling green needles! Gently shake the tree. A fresh tree will not have falling green needles            unless it is too dry.
*Tips of the evergreen should be flexible, not brittle.
*Try to select a tree that is in shade and has some protection from the wind.
*Is water available for the cut tree? 
*Don’t forget to recut the base of the trunk to allow the tree to more freely take up water. 
*Once the tree is up in your home do not forget to keep it watered!

A real tree at holiday time is a thing of joy. We respond to the sight, scent and feel of a live tree and the memories they evoke last a lifetime.  Have a happy Thanksgiving and enjoy the spirit of the holiday as we prepare for the Christmas and Hanukah season.

Giving the Garden a Cold Shoulder




Giving the Garden a Cold Shoulder….



Mother Nature is going to give us all the cold shoulder this evening!  It may seem to be hitting us a little early, but according to UK’s weather service, by October 18th we have a 50% chance of a frost or freeze. We have been experiencing a few low morning temperatures, but it looks as though Jack Frost has made his first date with Jefferson County for the fall. So, just what does that mean for our gardens?

First, harvest all tender crops such as tomatoes, peppers, etc. Unripe tomatoes can be picked and placed on the counter until ripe or wrapped in newspaper to be stored for a short time (only store tomatoes that are blemish and disease free). Cole crops, such as kale or broccoli, can not only handle a frost, but may taste better if harvested afterward. 

Garden cleanup is essential after all the crops have been harvested. Disease and insect control starts with disposal of spent plant material including discarded fruit. This is a great time to test your garden soil. If the pH needs to be adjusted (lime to raise it, sulfur to lower it), you have time to get the results and then apply any amendments before spring planting.

Some fall reminders include:

*You can still plant spring bulbs through mid-December, if necessary. 

*It’s getting a little late for transplanting peonies.

*Run over any fallen leaves with your mulching mower before putting them on your compost pile. Don’t forget to turn your compost pile occasionally during winter.

*ALL HOUSEPLANTS SHOULD ALREADY BE INDOORS!!! Remember that most houseplants are from tropical regions, there is nothing tropical about a frozen African violet or peace lily!

*Some temporary insect invaders may be seen indoors, but most of these are looking for warmth and do not want to live on you or your home.

*Do not store firewood up against the house to avoid wood eating insects (keep off the ground if possible). 

Along with the cool temperatures we have beautiful fall days to look forward to. Trees haven’t reached their peak colors yet and Thanksgiving is right around the corner. So sit back with a warm cup of apple cider, light a fire (or turn on a virtual one on TV) and enjoy our Kentucky fall weather!

Name This Bug!






 Name This Bug!




 We recently received this question by email:

    " I think my tree has a problem with pine beetles, can you help me?"

We identify insects (and diseases) that plague plants in and around the home. Just remember that we need whole insects!  Bits and pieces or insects stuck on tape are notoriously difficult to ID. If you have the insects, collect several (whole, not smashed) and place in a jar with alcohol. Bring them to our office for identification. We are located in the Urban Government Building and our office is open 8am to 4:30 pm, Monday thru Friday.  If we cannot ID them here, we can send them on to the entomology lab at UK.


Getting back to our answer to the question.....
 

What variety of pine do you have?

Have you seen an insect? If so where are you seeing the insects?

Are there holes in the bark/trunk?

Can you see what looks like sawdust at the soil level of the trunk?

Is there sap on the branches, bark or trunk?

Are the needles dropping off or appear wilted?



This is a link to some of the problems that pines have in our area.

We cannot come out on site. A certified arborist can evaluate the tree(s)and what you are observing. Valuable trees in our landscapes may need on site evaluation as soil, structures, slope and other factors in the environment may play a part in the health of these plants.

There's a New Bug in Town!





There’s a New Bug in Town!






We have been busy answering questions about the stink bug that is starting to plague homeowners.
A relatively new pest invader to our area, it is the Brown Marmorated Stink Bug (BMSB).  They were introduced to North America in the late 90’s from Asia and showed up here in Louisville in 2010/2011. 

For home owners they are considered primarily a nuisance.  Like the Asian Lady Beetle, they are attracted to our homes and other structures to find a place to overwinter.  They do not breed in our
homes, do not carry disease and do not bite(or feed)on humans.  

Excluding them from your home is the best control. Pest proofing includes sealing entry ways from cracks around windows, doors, pipes, chimneys, etc.  Once indoors insecticides are not advised.  Chemicals will kill the insects present but will not prevent the BMSB from re-entering
the area.    Try zapping them up with a vacuum cleaner to avoid most of their smell (they smell like strong cilantro) and the stain they may leave behind.   

The BMSB is an economic problem to farmers as they damage crops.  Our entomologists tell us
they feed on the sap of many different plants including fruits, vegetables, field crops and ornamental  landscape plants.  

When the weather warms in spring the BMSB will leave the protected areas where they have overwintered.
