Three Rules of Weeding in Your Georgia Garden

Weeding in Your Georgia Garden

All of Georgia has seen a large amount of rain this summer. Rain is great for our crops and also great for weeds and if you have gotten lazy with the summer heat your plots may have more weeds than crop. You are not alone! This may be a great time to review best management practices for weed control.

Weeds can be a big problem in a community or school garden.  A very big problem.  Knowing how to weed correctly will make this job less of a headache.   An informal poll was taken and we asked experienced gardeners to give their top three rules of weeding and we present them here:

Rule #1:  Get the roots out.

If you just remove the leaves above ground chances are the weeds will come back and you will need to perform the same weeding chore over again.  Many perennial weeds grow from underground roots and tubers.  Those need to be removed as well.

 

Weeding in Your Georgia Garden
Get those roots out!

Rule #2:  Remove the weeds before they make seeds.

If your weeds are allowed to flower and make seeds your work will get much harder.  Weed plants can make an incredible amount of seeds.  For example, common chickweed can produce 800 seeds per plant.  Dandelion flowers can make 40-100 seeds.   Crabgrass can produce 53,000 seeds per plant and pigweed can produce over 200,000 seeds per plant.  Don’t let those weeds flower!

Weeding in Your Georgia Garden
You don’t want this!

Rule #3:  Don’t let weeding get out of hand.

If you don’t routinely remove weeds you could be looking at a plot of weeds that seems overwhelming to tend.  Your vegetable production will suffer as the weeds take up the water, nutrients, and space that should be used for your plants.  And, it will take a lot of initiative to start the long process of taking back that space from the weeds.

Weeding in Your Georgia Garden
Don’t let weeds take over your community or school garden plot.

Knowing what weeds you have could be helpful in coming up with a long-term weed management plan.  Your local UGA Extension agent can help with weed plant identification and help you find strategies to minimize weed issues.

Happy Gardening!

 

Resources for School Gardening in Georgia

In most of our state, school started today. I have been contacted by several teachers who are interested in starting school gardens this year. Many of them have had little experience in the garden and they envision a beautiful space where learning takes place outdoors everyday. For those of you who are just beginning your school garden journey I want to recommend a few resources for you.

First, the publication Steps in Starting a School Garden. This guide will take you step-by-step through starting a successful, sustainable school garden. From gathering an effective garden team to what to plant, this guide will help you get started.

Next, bookmark the school garden resources webpage. This resource contains garden ideas, lesson plans, grant information, and supporting information on why school gardens are important. Visit it often!

Finally, make sure you know your local UGA Cooperative Extension agent. I may be biased but if you don’t know what is going on in your local Extension office you are missing out. Agents lead workshops in horticulture, nutrition, food safety, etc. They also may know what types of school gardening programs are already in your county.

Kickin’ it with Kale during 2018’s Farm to School Month

If you already have a school garden and are ready for the school year, don’t miss out on Georgia Organic’s Kickin’ it with Kale campaign for October’s Farm to School Month. Go to the website and sign up for resources. The first 300 people/groups to sign up can receive free seeds. I will be honest and say that I am not a big kale fan. Maybe this is the year I change my mind! Next week I will post information on how to plant those small kale seeds to ensure success.

Happy Gardening! And have a GREAT school year in the garden!

Avoid Heat Stress in the Georgia Community Garden

I have gotten some requests to repost this information about heat stress. It is definitely summer in Georgia so we all need to take care.

Summer heat can be dangerous, especially with the heat and humidity we are experiencing this summer.   We went to a professional to get tips on how to stay safe in a hot, humid Georgia garden.

Heat Stress in the Georgia Community Garden
The Weather Channel knows heat!

Millard Griffin is a Certified Safety Professional with Environmental Resources Management (ERM).  He has vast experience dealing with heat related issues on environmental projects from the Florida Everglades to the Gulf Coast of Louisiana.  He knows heat and humidity.

Heat stress is a real concern for those working in the garden.  Especially for those of us who aren’t out there every day.  Heat stress is defined as any situation where the human body is unable to cool itself by sweating.  This can lead to several conditions including heat rash, heat cramps, heat exhaustion, and heat stroke (a medical emergency).

Tips to Prevent Heat Stress

To prevent these conditions Mr. Griffin gives us the following tips:

  • Acclimatize to the heat.  Work a limited amount of time outdoors and gradually increase your amount of time in the heat.
  • Avoid the high heat periods of the day.  Get your work done early in the morning or late in the day.   Avoid the hours between 2 and 6 as the heat loads are typically higher during these hours.
  • Take frequent breaks in a cool area.  Taking breaks in an air conditioned area is preferable but, a shady area will work.
  • Limit exposure to direct sunlight when possible.  Plan your workday to take advantage of shaded areas.
  • Drink plenty of water.  Take a water break at least every hour, drinking cool water.  Also, drink water before working in the garden.  Hydration is key.
  • Avoid caffeinated beverages and alcohol.  These are diuretics and cause your body to lose water.
  • Wear light colored, loose fitting clothing and a hat.  Certainly use sunscreen to protect against UV rays on all exposed skin.
Heat Stress in the Georgia Community Garden
Work in shade whenever possible.

Monitor Yourself

It is preferable to work with another gardener so you can monitor each other.  If you notice extreme sweating, dizziness, nausea, or muscle cramps STOP WORKING.   Head indoors, hydrate and cool down.

Certain people are more susceptible to heat stress – the elderly, children, pregnant women, and people who have just moved here from a cooler climate.  Certain medications can also make someone more prone to heat stress.   Mr. Griffin recommends checking with your doctor if you take medications.

Knowing this information will help keep you safe in the Georgia summer heat and make your gardening experience a more pleasurable one.

Remember georgiaweather.net is a wonderful resource for weather information.

Thanks Mr. Griffin for the tips!  Stay safe and

Happy Gardening!

 

 

The Great Georgia Pollinator Census August 2019

August 23rd and 24th of 2019, citizens of Georgia will be conducting the first ever statewide pollinator census. This includes YOU if you live in Georgia! You will want to be a part of pollinator history!

We have been working towards this project for some time and even though it is still 14 months away, we want to make sure that every Georgia citizen has the date marked on their 2019 calendar. We have already been asked a few questions so I wanted to answer those most frequently asked:

What is the Great Georgia Pollinator Census? The Great Georgia Pollinator Census is a statewide project where all Georgia citizens will be asked to count pollinators on either August 23rd or 24th of 2019. Training and all supporting information will be provided through the website, https://GGaPC.org, closer to the August 2019 date.

How will it work? Each citizen scientist (YOU) will choose a favorite pollinator plant that is blooming in their garden for counting. You will count all the insects that land on that plant during a 15-minute period. After you tally the counts, you will upload your data to the webpage. Very simple. The data will be used for researchers to see a snapshot of which pollinators are at work in Georgia on those dates.

Do I have to be an entomologist to participate? NO, definitely NOT. We will be asking you to place the insects you see into one of eight categories:

Carpenter bees
Bumble bees
Small bees
Honey bees
Wasps
Flies
Butterflies
Other insects

The online training, conducted and posted online in 2019, will teach you how to tell the difference between flies, bees, and wasps. We will give you the tools to understand the basic skills needed to place insects in the categories. It will be very simple and straightforward. Of course, we will be available for any questions.

Can school groups participate? ABSOLUTELY! One of the reasons for the August date is to make sure school groups do participate. We will have lesson plans available for teachers use. We have conducted smaller censuses and school groups have really enjoyed the activities. The teachers can tie the census to their STEM activities.

If you are a teacher and have a lesson plan on pollinators that you want to share we would love to put the plan on our website and to feature you on upcoming social media. Just email me at beckygri@uga.edu to submit a lesson or for more information.

What about families? Can my small family participate? OF COURSE. The census is set up so that individuals can count in their gardens.

Will groups be holding special events around the census? YES, the State Botanical Garden in Athens and the Coastal Botanical Garden in Savannah have already started planning special events. Other gardens will follow. Also, contact your local UGA Extension office to see what they have planned.

Starting in January 2019 we will have supporting social media so that as you get ready for the census you will have fun, and educational, snippets to use in classrooms or in family discussions.

Why are you announcing the census so early? So that everyone can mark those dates on their calendars. And, it gives those who don’t have a pollinator garden time to design and plant one! (https://ugaurganag.com/pollinators)

What can we do now to get ready for the census? Plan and plant a pollinator garden, check the webpage and bookmark it (https://GGaPC.org), and contact me at beckygri@uga.edu if you have any questions.

Be part of Georgia pollinator history. Mark your calendar! Happy Pollinator Week 2018!

Soil Temperatures in Your Georgia Garden

Soil Temperatures in Your Georgia Garden

With the recent warm temperatures it is easy to be seduced into planting your summer crops now.   It is tempting to plant our vegetable transplants and seeds; we can’t wait for that first juicy tomato are a crunch pepper!  Be aware that soil temperatures are very important for success with your early summer plantings.

Soil Temperatures in Your Georgia Garden
Pepper Seedlings

Soil temperatures need to be 60-65 degrees F and rising at the 4 inch soil depth before you plant your summer crops.

If you install a transplant too early the roots won’t grow and the plant will just be sitting in the soil.  If we have a large amount of rain, which seems to be the norm this year, your new plant will just be sitting in wet soil.  This could mean early disease issues.

This morning the Ballground weather station, near my home, indicated a 4-inch soil temperature of 54.6 degrees F. In Griffin the 4-inch soil temperature was 56.8 degrees F while Valdosta reported 63.5 degrees F.

If the soil temperatures are not warm enough for seed germination, early seed plantings could rot.

The roots need to be actively growing to absorb water and nutrients.

If we plant and fertilizer summer vegetables too early we will be wasting fertilizer.  The plant roots simply can’t absorb it.  This fertilizer could get washed away, wasting your time and money. Also, this leached fertilizer could be problematic for our watersheds.

Determine your soil temperatures.

To determine your soil temperature at the 4 inch depth visit www.georgiaweather.net.  Click on the station nearest your garden.  Or, you can see a summary of soil temperatures across the state.

Newly planted tomatoes. Waiting until the soil temperatures are warm enough is one step to success for your summer garden.

Remember the rule of thumb is play it safe and wait!

What You Need to Know About Aeroponic Tower Systems

Schools with limited outdoor space and teachers who are uncomfortable with traditional agriculture are turning to aeroponic tower systems to grow food for the classroom. Cobb County Cooperative Extension office has installed one of the systems in their office and have had a few harvests of leafy greens and herbs. I recently talked with Daniel Price, a Cobb Extension program assistant, about the system.

How the Tower System Works
Aeroponics are a subset of the older hydroponics. They both are soilless systems that rely on a nutrient water blend. As a college student, a long time ago, I worked in a hydroponics lab. The nutrients flowed continually around the plant roots in an open system. We were continually concerned about bacteria and viruses infecting the nutrient system. Things have changed with the updated aeroponics.

Rockwool seed germination cells.

In aeroponic tower systems seeds are germinated in a special media called rockwool. Once the seedlings grow a few true leaves they are moved to the tower system. Cobb County’s tower example has 20 plant spaces with an outer ring for plant support.

The inside of the tower system. Look at those roots!

The nutrient water blend is housed in a 20-gallon drum at the bottom of the tower. The blend is rained on the plant roots for 15 minutes per hour. The system is enclosed which helps limit contamination of the nutrient blend. Plant lights surround the tower and are on a timer. Basically once the system is set-up everything is automatic until you are ready to harvest. Daniel says that it takes 2-3 weeks from lettuce seedlings to a full harvest.

The tower garden does not take up much space.

Issues to Consider
*This tower system cost approximately $1,000. This included the hardware, seedling starter kit, pH tester, pH buffer, and a start pack of nutrients.

*Leaks are sometimes a problem if the tower is not on very even ground.

*The pH needs to be routinely monitored but if it falls out of the recommended range, it is not too difficult to adjust.

*Algae growth is common around the rockwell plug and most experts do not think it is a problem. It just looks concerning.

*This system does not totally eliminate pest and disease issues.

Cobb Extension personnel are happy with the system. They have enjoyed the harvests and have not had any serious issues. Although they have only grown leafy greens and herbs at this point, the plan is to expand the plant selections. Daniel uses the tower as a teaching tool and has held several classes about aeroponics. Cobb Extension encourages anyone who wants to see the system at work to visit their office.

Thanks, Daniel, for showing me around the aeroponics system!

March 19th Hands-on School Garden Day

Georgia Ag Awareness Week is March 19th through March 23rd. Monday, the 19th, is Hands-on School Gardening Day, a day to showcase Georgia school gardens. How will you celebrate? Use social media, the local paper, or even email proclamations to let your administration and community know about your school garden. Plan a special garden workday. Or, give tours of the garden. Definitely plan something special.

I first worked with a school garden in the mid-1990s. At that time the garden was a beautiful space that the teachers used for outdoor reading time or inspiration for writing assignments. The garden itself wasn’t used for instruction. Times have changed. School gardens are now used to teach geography, math, history, literature and science.

Atlanta Academy elevates their garden due to lack of available land.

Food plots are used to teach basic agriculture and nutrition through harvest taste tests. Younger students explore sensory gardens. Older students use produce from their school gardens to learn marketing and business skills as they model farmers market sales. These garden spaces have become a major part of our school curriculum.

Due West Elementary School in Cobb County uses the garden to teach math!

Research papers prove the benefits of learning in an outdoor environment. Georgia’s Department of Education recognizes this with the agriculture focus for science, technology, engineering, and math (STEM) certification. The verdict is in – school gardens are good for our students.

On March 19th as you celebrate Hands-on School Garden day, take a moment to recognize the hard work that you put into the program. Share your photos with us on our UGA Community and School Garden Facebook page. We want to celebrate with you!

Happy Ag Week 2018!

Is Your Garden a Winter Mess?

With the long-lasting cold winter temperatures and snow (snow!!) this winter how does your food garden look and can it be salvaged? According to Home Garden Vegetable Specialist, Bob Westerfield, we are better off just pulling up spent broccoli, cauliflower, cabbage and leafy greens. Leaving them in the garden creates a harbor for disease and insect pests. Brussel sprouts is an exception. If your Brussel sprouts look good, you can leave them and they may still produce.

A mushy winter mess!

Since playing in the garden is limited consider soil testing now and making your Spring garden plan. You will be able to plant new cool-season plants soon enough!

Happy Gardening!

Save the Date(s)

There are many fantastic events planned for 2018 so mark your calendars and save these dates:

Fresh Food Translates In Any Language

My daughter, Mady, moved to Lovere, Italy, in September. I asked her to give us an international perspective on fresh food and gardens for this week’s blog post. She writes….

I would like to begin by stating that I am in fact no way professionally qualified to educate you on the knowledge of plant life. I do not know when the best time to plant spinach is or what Botrytis and I’m only about 85% certain where the pistil is on any given flower. However there is one thing I feel very qualified to speak on: EATING GOOD FOOD.

Mady Griffin enjoys fresh, local food in Italy.

About three months ago I packed up my little room in Athens, Georgia and headed across the ocean to settle in a small town in the north of Italy to teach English for a year. I took as much as I could with me such as pictures of my family, books in English, and my classic Southern charm. However, one of the most important things I took was my something my mother gave me: An appreciation for well grown and well cooked food. An appreciation that Italians are crazy about.

I was lucky enough to get settled with a host family who have given me a good education on delicious cold cuts, cheeses, wines, and of course produce. Many products here like to guarantee you that they’ve been locally produced with local ingredients and if they have not they are quick to tell you where they came from. I have had cappuccinos made with milk from within an hour of where I live and we’ve had local cheeses, wines, chestnuts, and even a fresh rabbit from the farm of a family-friend. All of these were made into a variety of different delicious meals, but one particular part I want to write about is one of my new favorite meal traditions. The tradition of after-meal fruit. After grains, meats, salads, and before coffee we indulge in whatever fresh fruits my host mother has found at the store. These happen to be whatever fruit is in season to make sure what we’re eating is fresh and local. Since we’ve transitioned into fall I’ll highlight three of the fruits I’ve gotten to enjoy lately before the frost comes in.

Persimmons (Italiano: i cachi)

My host family has lived in a couple different countries before settling back in Italy and my host mother said one of the things she missed most about home were persimmons. In the town we live in they’re very common and people even harvest from trees right in their backyards. Around the beginning of fall these red/orange fruits begin to become ready for picking. However once the fruit has been has picked that does not mean it’s quite ready. You have to wait until the fruit inside has just started peeling away from the skin which you can feel by gently squeezing the fruit. Then you easily pull the top off, dig out the tough skin just inside the persimmon and dig in!

Clementines (Italiano: le clementine)

Clementines are in abundance during this time and it’s easy to grab a couple here and there not only after dinner, but also for a quick snack or “merenda” between meals. They’re perfect since they don’t need to be washed and can be placed on the table for any time of the day. Like in America many children eat them because they’re so easy to peel and can be bought without seeds.

Kiwi (Italiano: i kiwi)

This one took me a bit by surprise since thinking of kiwi brings up images of tropic New Zealand and not cold northern Italy. However sure enough another family friend brought along a bundle of fresh sweet kiwi for the family to share. Since I had not ever tried a kiwi myself I was taught the proper way to enjoy them. Cut off the top, slowly peel of the skin with a knife and then cut off the bottom. Then you can slice it in half and eat it straight. It’s delicious and sometimes hard to not stop at just one or two.

No matter what the meal is if it’s on an Italian table you know they put in a lot of thought and effort into the quality of their meal from the ground to your plate. I am excited to see what other ways Italians use their gardens to perfect their historical art of cooking. Until next time, arrivederci.

Buon giardinaggio!
