Ornamentals & Turf Course

plant diseaseThis year has been unique for everyone. All of us have been impacted in one way or another. We sincerely hope that you and your family are doing well and the pandemic has not touched you or your family. We at UConn Extension have been striving to put this course online for your convenience. While we understand that an online course is simply not the same as in person, this is where we are in the world today. We will certainly miss the interaction we have with all of you in the classroom as well.

There are some advantages to having an online course though, first you can work when it’s most convenient for you. You can also take the course in small chunks rather than sitting through a 3-hour lecture. You don’t have to leave your job or business to take the course either.

This Short Course is an in depth review of the information necessary for studying and fulfilling the requirements of the Ornamental and Turf/Golf Course Superintendents State of Connecticut Supervisory Pesticide Applicator Certification exam. A student completing all the modules, working through the quizzes, and studying resources materials independently should be able to successfully pass the examination, both written and oral state exam. Expect to spend at least 8 hours on each module.

Class topics are: Pesticide Laws and Regulations, Pesticide Safety, Botany and Ornamental Identification, Plant Pathology and Ornamental Plant Diseases, Entomology and Insect Pests of Woody Ornamentals, Area and Dosage Calculations, Turf Management and Weed Management. Each class begins with a basic overview of the science then takes an in-depth look at specific pests, their biology and control.

We have developed the course into 8 modules. Each module is broken down into Parts. Each part begins with learning objectives followed by slides with a narrative. PDFs of the slides are available for printing. Each Part will close with a summary and quiz on the contents of the part just viewed. Please take the quizzes seriously and take the time to write out your answers, as this will help you retain the important points from each Part and be useful for studying for the final exam as well as the state exam.

Each week on Tuesday evenings at 5:30, we plan to introduce a new module for you to work through during the week. The following Tuesday we will do a short debrief of the module you just completed and introduce the next module, again followed with a debrief the next Tuesday and so on for 8 weeks.

This does not include the required Pesticide Applicator Training Manual, (aka “The Core Manual”), which can ordered from UConn MarketPlace under the College of Agriculture, Health and Natural Resources Extension at:
Click on Department of Extension box.

The core Manual can also be found and downloaded from the “National Association
of State Departments of Agriculture” at the following link:

An additional resource which is very highly recommend by CT DEEP, and is free from the website below it is called, “Turfgrass Nutrient and Integrated Pest Management Manual”, edited by Tim Abbey. This is really is a must read and necessary resource:

There is also an optional manual called “Ornamental and Turf, Category 3 manual” available from Cornell, it cost $41.00 plus shipping and handling.
Check for used copies of these books with your colleagues or online, yes, even check Amazon.

Plant Evergreens for Holiday Decorating

Article By Dawn Pettinelli

With the holiday season upon us, many choose to decorate their homes, both inside and out, with fresh cut greens. Making holiday decorations can be simple, satisfying, and a great way to spend some time outdoors and maybe, do some much needed pruning. Over the years, I have planted a good number of broad and needle-leaved evergreens both for their landscape value and as fodder for holiday decorating. Even a few branches from 2 or 3 evergreens can be used to create table arrangements, a decorative swag or container for the front door or to fill a window box or two.

Ever wonder how this custom of cutting and displaying evergreen branches came to be? Bringing in branches of evergreens during the short, dark days of December was practiced in pre-Christian days by inhabitants of northern European countries. This was done to ward off evil spirits. Trees that held their needles throughout the cold winters symbolized the earth’s fertility and eternal life. They served as a reminder that the earth would become green again.

Evergreens are pretty much a staple in foundation plantings. You may even have an evergreen hedge, mixed shrub border, or a few specimen shrubs or trees. Of course, if you want to have greens for the holidays it makes sense to wait until December before pruning them. While this may not be the optimal time of year, my plants seem to do quite well if a few branches are judiciously removed for decorative purposes. The majority of the pruning; however, is done in summer after new growth is fully expanded.

Whether planning a new planting, renovating an old one, or deciding on a shade tree or specimen shrub, consider varieties suitable for holiday use. If it is scent you are after, balsam fir is hard to beat but most evergreens emit a fresh, woodsy aroma. Balsam fir will grow into a good sized tree unless you decide to use it for your Christmas tree.  Fraser and white firs are also excellent candidates for a tree or greens.

Almost any species of pine is suitable for decorative use especially if you choose the young growth. Hemlock is very attractive but loses its needles quite rapidly if placed in warm temperatures. Spruces are lovely but prickly to work with. A recent speaker at our garden club suggested that putting on a pair of those disposable gloves will enable you to handle the spruce without getting stuck by the needles. A good number of yards are homes to yews, junipers and arborvitae. Some varieties are better for decorative purposes than others. Leave the ground-hugging junipers alone though.

For gold tipped foliage, quite attractive indoors or out, consider adding a false-cypress (Chamaecyparis pisifera ‘Filifera) or related plant to the landscape next year. These fine-textured plants can get somewhat open with age attaining a height of 4 to 20 feet.

Use other evergreen plants in mixed arrangements. Look for wayward branches of boxwoods, hollies, andromeda, mountain laurel, euonymus (especially the variegated types) and evergreen azaleas. Staghorn sumac berries, rosehips (not from multiflora roses) and winterberry fruits as well as pinecones and other seed pods can be used to accent your decorations.

When cutting for decorations, choose well formed branches with thick foliage. For small indoor arrangements, one might want to rinse the branches to remove dirt and insects. Stems can be recut and placed in water for several hours before arranging to keep them fresh. When creating outdoor swags, window boxes or other containers, generally these steps are skipped and the freshly cut greens are just used as needed.

A swag is probably the easiest and simplest of holiday decorations. It is basically a grouping of evergreen branches tied together in a pleasing manner. Branches can simply be wired together but beginners might benefit from using a wire coat hanger stretched vertically so that the hook can be used as a hanger.

For a swag, cut at least 3 pieces of greenery 18 to 24 inches long and 6 to 12 shorter pieces. Attach the 3 longer pieces to the coat hanger with the longest branch forming the center. The shorter branches can be wired on each side to increase the fullness of the swag. Fill in as needed with more branches of greenery and finish with a bow, a few springs of holly, cones or ornaments using thin green florist wire to attach.

Be adventurous and make a holiday swag or other arrangement this year. Perhaps your evergreen decorations, inside or out will become a family tradition. The quantity of evergreen material right in your own yard may surprise you. Just remember to prune wisely and add another evergreen or two each year for fuller and more varied arrangements.

Here’s to a safe, happy, and peaceful holiday season.
