Fall Festivals and Your Community Garden

October means fall festivals and seasonal events across the state of Georgia. From Blue Ridge to Savannah, from Augusta to Columbus everyone is celebrating fall. What is your community garden doing to celebrate? This time of year is perfect for emphasizing the “community” in your garden. Some suggestions:

Host scarecrows in the garden! This is done with flair at the Atlanta Botanical Garden and the Research and Education Garden in Griffin. Why not your garden? Ask local businesses, civic groups or schools to create a scarecrow to exhibit. This could be a contest where visitors vote and a local celebrity awards the prize. For a twist have the exhibitors create/decorate crow birds which can perch with a spooky flair in the garden. Craft stores sell crow bird props at low prices, easy to decorate.

Season storytelling in the garden for all ages. Enlist some garden members or community leaders to lead a spooky storytelling event in the garden. Reading an Edgar Allen Poe story or poem dressed in period costume would create excitement for sure. If your garden is large enough you could station readers around the plots.

Have a pumpkin decorating contest. Even if your garden does not grow pumpkins you could purchase some from a church pumpkin sale. Or, you could use other vegetables. Have visitors decorate a pumpkin/vegetable and take the opportunity to educate community members about growing vegetables.

Celebrate with an open house. If your community already has a scarecrow exhibit or other events simply add an open house to be part of the larger town effort. An open house does not to be much work on your gardeners and would be an excellent opportunity to let your town know about your beautiful space.

Whatever you decide to do, enjoy the fall season! You’ve earned it!

Flooding in the Community Garden

Many of our community gardens are located in floodplain areas (which is why the community is not using that land for something else!) or near creeks or rivers. Recent weather events may have left parts of your community garden flooded. UGA food safety experts ask us to think about the safety of our produce from the impact of flood waters. Farmers have to think about this on a large level and it is a concern for us. Experts from UGA released important harvest information for farmers ahead of this hurricane. Also, the FDA has guidance for flood affected produce.

If a flooding creek encroached on your garden what did that water bring with it? Possibly contamination from pathogens harmful to humans. What about chemical hazards from another site that washed into your garden? These could be serious. If flooding did occur in your garden, I advise you to speak with your local UGA Extension agent for advice from a food safety perspective.

Thoughts on Plant Disease in the Georgia Garden

Every year seems to bring a new set of challenges for the Georgia gardener. Some years the drought leaves our gardens in the dust and some years it never seems to dry out. Some years we break record heat waves and some years fall comes early. However, plant disease never seems to give us a break. As we try and coax healthy cool-season crops out of warm soil I thought it might be nice to take a look at some disease facts so we can come up with strategies to help ourselves.

Fact #1: Healthy plants can withstand disease better than stressed plants. Knowing what healthy plants look like (is that mottling part of the normal leaf or could it be a virus?), what your plants need in the way of fertility and water, and what conditions those plants need to thrive will go a long way in managing disease. If your plants need full sun, plant in full sun. Shade will stress your plants and open up the possibility for disease. Have your soil tested for fertility and use the results to meet the needs of your plants. Take away: Strive for healthy plants

Fact #2: Most of our disease-causing agents are fungi. We do battle some bacteria and some viral diseases but overwhelmingly fungi are our problem. Most fungi need a wet environment. You probably notice during rainy periods disease symptoms seem to magically appear. Community gardeners tend to plant our plots as full as possible limiting air circulation around the plants. Moisture stays on the leaves creating a perfect environment for pathogens. Take away: Limit overhead watering as much as possible. Make sure your plants have adequate air flow around them.

Fact #3: Often pathogens overwinter in garden debris. Many times fungal survival structures, like spores and mycelia, will last for months(years) in organic matter, leaves, and garden debris creating an environment for a reinfection during the next planting cycle. Take away: Clean your garden plots after every season.

Fact #4: Most fungicides are used as preventatives and not as a cure for disease. Once a plant has been infected it is hard to cure that plant. The pathogen is already present, has done damage and gardeners cannot rely on fungicides to fix the problem. Take away: Plan ahead for disease management.

Fact #5: Some pathogens will infect many types of plants but many pathogens have a narrow plant host range. Rusts (Uromyeces spp.) are common among bean plants and powdery mildew (Oidium spp.) always seems to find all types of squash. Take away: Know what diseases normally affect the plants you have in your garden. Learn to recognize the pathogen signs and symptoms. Use your local Extension office to help identify the diseases that plague you. Your agent can also help you devise a plan of disease management.
