Dear Lyon County Gardener,
Summer is here at last! We had an extra ‘winter’ it seemed, following linen britches, dogwood and blackberry winters. We need a new name for this extra late winter. Suggestions? The flowers seemed to enjoy the cool spring, spring bulbs lasted for a long time and roses and other flowers have been beautiful! What’s Going On: For the next Master Gardener Class I would like input of interested people on
time of day, frequency and time of the year. See page 4 for details! I hope to offer a Winter Low Tunnel Vegetable webinar in July or early
August. I will send out additional information. The Lyon County Farmers’ Market plans to open by June 25. Vendors hoped
to start earlier but cool weather and rains have held back production. Mark your calendars for the Celebration/Customer Appreciation Day on Saturday, July 16, 7:30-11:00. The Lyon County Master Gardeners are working on activities and information on butterfly, pollinator and hummingbird plants for the garden!
For hunters and wildlife enthusiasts on August 29 we will offer a Wildlife Food Plot class in the evening. This will be multi-county and held at the Marshall County Extension Office.
On Thursday, September 15, we will offer a workshop on Spring Flower Pots from 10:00 a.m. to 12:30 p.m. Participants will create their own combination bulb and winter annual flower pots. They are a welcome sight come spring! Cost is to be determined.
Sincerely, Extension Agent for Agriculture and Natural Resources

Hypertufa Pot Class:
Create your own hypertufa pot at our class on Tuesday, June 21 at the Lyon County Ex-tension Office from 9:30 a.m. to 12:00 p.m. These pots are intended to resemble old Eng-lish stone troughs. Size and shape is dictated by the forms used. They are a mix of Portland cement, perlite and sphagnum peat moss. Pots or troughs will need to remain at the of-fice until they are hardened enough to move. This can be 2-3 days depending on the size. Cost will be $10 per person payable with res-ervations.

Master Gardener News
Visit the Master Gardener website at http://lcmga.yolasite.com/ for more information and pictures of
Lyon County Master Gardener events, classes and activities. The site is maintained by Moira Miller, MG.
Blueberry Demonstration Bed: Sixteen blueberry va-
rieties were planted in April. Because the bed was pre-
pared last fall we only needed to dig holes and plant!
There are a total of 23 plants. They include northern high
bush, southern high bush, one rabbiteye and several half-highs
(crosses of different species). Most were selected based on University
of Kentucky recommendations. A few we are trialing out of curiosity.
We will look at plant size and habit, fall leaf color and, most important-
ly, yield, fruit quality and flavor! Most are mid-season ripening. Late
season ripening may have more issues with the invasive fruitfly, spot-
ted-wing drosophila which builds up in numbers as the season pro-
gresses. The pH of the bed at present is 5.0. We are mulching with
pine bark to help maintain an acidic soil pH between 4.5 and 5.0.
Members Moving!: We will miss Gail McQuigg from our group.
She has sold her house and moved to Florida. Gail hosted the MG
monthly meeting in May. We were happy to visit with her again and
see her beautiful home before she moved. We wish her well and ap-
preciate all her work at the Farmers’ Market and other
events!
The Annual Flower Trial Garden has been planted and
will be scored monthly. The same flowers are planted in
several locations across the state. The evaluation scores
are compiled at the end of the year. So far most are do-
ing well, much better than last year. The sweet alyssum
variety seems to be fading fast.
New Flower Bed: Peg Barnett redesigned the herbal tea garden into a
butterfly and pollinator garden. We have been attacking the crabgrass that
came in like a carpet and will have it mulched soon. It will be a beautiful
addition to the demonstration garden. Come visit the garden and
meditate a moment with the frog!
Annual 4-H Mother’s Day Flower Pot Event: This is a fun after-school ac-
tivity where youth can learn the basics of selecting and planting combination
flower pots. A PowerPoint presentation was made by Natalie McPherson and
then several MG helped with planting, bows and cards. Carrie Barnett worked
hard to coordinate the MG and youth for the event! Thirty kids had a great
time and loved the flower pots and cards they created for mom!
Planting blueberries is hard, serious work
as you can see in the above pictures! Top

ledge.. In the bottom photo, left to right,

nett.

Dogwood Anthracnose By Kim Leonberger, Extension Associate, and Nicole Ward, Extension Plant Pathologist
Anthracnose of dogwood is a common problem in Kentucky. Symptoms on landscape and forest dogwoods often first appear during wet periods in late spring. If left unmanaged, the pathogen spreads, eventually resulting in plant death. Selection of resistant varieties and maintenance of tree health are critical for disease prevention. Anthracnose Facts:
Leaves may develop medium-to-large spots with purple borders or scorched tan blotches that enlarge to kill the entire leaf. Infect-ed petioles and branches exhibit dieback, typically beginning on lower branches . Cankers with a dark brown discoloration under the bark may develop on limbs. The development of trunk sprouts increases.
Other landscape trees can develop diseases also called an-thracnose; however, these result from different fungal pathogens and symptoms vary depending on the type of tree.
Disease is favored by cool, moist periods. Infection may occur throughout the growing season, as long as conditions are condu-cive.
Caused by the fungus Discula destructiva.
The pathogen survives winter in infected plant tissues, such as leaf debris and cankers. Management Options:
Select disease resistant cultivars, such as Oriental dogwood or culti-vars developed from the ‘Appalachian’ series.
Inspect all trees prior to purchase and installation for symptoms.
Do not transplant forest dogwood into landscapes.
Prune trees to allow for increased air movement and leaf drying.
Select good planting sites that allow for adequate sunlight.
Maintain plant health with proper nutrition, irrigation, and the addition of mulch.
Avoid injuries to trees.
Prune all dead, dying, or diseased branches from trees. Fungicides may be applied preventatively. Contact the Lyon Coun-ty Extension office for more information on fungicide use.

Services Offered by Extension
Susan Fox, Lyon County Extension Agent for Agriculture and Natural Resources
Lyon County Extension offers free soil testing, up to 4 per homeowner per year. Soil testing will tell you your soil pH, phosphorus, potassium, calcium, magnesium levels are and gives recommendations on nitrogen applications. Extension also offers free plant disease and insect identifica-tion services. We do need good samples, sometimes a site visit is required. We have trained pathology and entomology specialists at Princeton and Lexington.
Master Gardener Class Information Request! If you are interested in participating in a Master Gardener Class and volunteering for the Lyon County Extension horticulture program I invite you to share your prefer-ences on how the class is offered. Circle all that apply and return to the Extension Office! There are 12-14 sessions and a field trip. The class is held at the Extension Office, most classes are 3 hours long. Participants are trained as Extension volunteers. The first year participants give 40 volun-teer hours (it goes fast!) and then, in subsequent years, 20 volunteer hours are required to maintain the Master Gardener status. Volunteers are required to have background checks (we send them in and can’t use one from another organization). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Name: Phone number: Addresss: Class Day/Time: Mornings Afternoons Evenings Saturdays Anytime is good.
