Community and School Gardening in Georgia

Helping Community and School Gardeners Succeed!

This gardening blog is put together by Becky Griffin, Extension Community and School Garden Coordinator. It is designed to help community and school gardeners succeed by connecting them to UGA Extension and other research-based resources.  Here you will also find information about  programs designed to improve pollinator health in the garden.

 


The Importance of Leadership in the Community Garden

The last couple of weeks I have visited several community gardens. Most of them are flourishing and it exciting to see! Two of the gardens are on the brink of collapse. Why? Lack of leadership.

People are the most important part of a community garden. Leadership, most often in the form of a garden board, is necessary to:

Manage plot assignments
Organize common area work days
Promote the garden
Secure needed funding
Act as a liaison with the outside community
Ensure harmony among gardeners
Help teach those who are new to gardening
Plan fun garden events!

This is essential to the sustainability of the garden.

It is always sad to see failing gardens especially when it could have been prevented. At their best community gardens are a safe gathering spot for fellowship, learning, and growing good food. The publication How to Start a Community Garden: Getting People Involved is an excellent resource even for established gardens. Also, the American Community Garden Association has some tips for garden leaders.

Keep your garden organization in order so you can enjoy the harvest!
Happy Gardening!

Earth Day 2019

Earth Day falls on Monday, April 22nd. It is a good day to appreciate our Earth and to evaluate how we are caring for it.

The first Earth Day was in 1970. The April 22nd date was chosen because it was after college spring break but before college exams. The expectation was that college students would be an internal part of that day and they were. Several of those students have grown to be very involved in the environmental movement. In 2020 we will celebrate the 50th anniversary of the first Earth Day.

In my household we usually celebrate the day with a huge feast feeling grateful for what we can grow and very thankful for the farmers that grow what I do not. Each year we have a theme. One year it was a native peoples feast featuring bison burgers. One year it was honey-themed and another year I featured strawberries. The point was to take some time to appreciate our Earth and the food we grow.

We can all take stock on how we treat our natural resources. As a vegetable gardener are you following best management practices in your garden? Are you using integrated pest management to handle pests instead of reaching for a pesticide? Are you creating and sustaining healthy soil? How are your composting skills? Can you pull the weed instead of using an herbicide?

This time of year I always create a goal towards improvement. What about you?

Happy Earth Day!

Our Georgia Weather Stations

If you don’t routinely use https://www.georgiaweather.net you are missing out. This website contains information from approximately 100 weather stations placed all across our state.

After you select your area from a drop-down menu a wealth of information pops up including rainfall amounts, soil moisture, and soil temperatures.

Right now in mid-April we are all concerned about soil temperatures. No matter what the air temperatures are reading, soil temperatures are what matter for seed germination and root growth. The weather station data shows soil temperatures at 2 -inch, 4-inch, and 6-inch soil depth. Today the 4-inch soil temperature for my location in Blairsville is 54.1 F degrees. This is way too cool for any warm-season crops.

I can also look at past data to see what the last frost dates have been for my area. The last few years have seen some swings from April 30th last year to early April the three years prior.

This information can help me make calculated and informed decisions about planting times. I highly encourage all of you to make use of this free tool.

Georgia Agriculture Awareness (and Appreciation) Week

As the 2019 Georgia Agriculture Awareness week draws to a close I hope everyone took some time to enjoy some Georgia Grown food. I know my family did! Tuesday night we enjoyed Caprese Chicken made with Georgia chicken and tomatoes, topped with homegrown basil. I enjoyed seeing photos of how you all celebrated School Garden Day on Monday.

This year especially I have been reflecting on how very appreciative I am of Georgia agriculture. Every night I am blessed to be able to have a nutritious, delicious meal thanks to those who grew it. Some of the food we grow ourselves, in that wonderful Georgia soil, and some we purchase from other growers.

This past year our farmers have dealt with incredible difficulties from hurricane Michael and recently flooding. Many people don’t realize that the overwhelming majority of our farms are family operations. Georgia agriculture has been hit hard. It has been a sobering few months.

This week I have resolved to even eat more locally and make sure that I am supporting Georgia agriculture as much as I possibly can. Thank you, Georgia growers, and this week especially our hats are off to you! #GaAgWeek2019

Indoor Seed Starting-Part Three

Now that your seeds have germinated the fun begins! When most of the seedlings have germinated and look strong, think about removing the top dome. You can do this gradually by placing it askew on the seed tray for a day or two before totally removing the top.

It is important to keep the light just above the seedlings and to move it as the seedlings grow. If the light is too far from the seedling, the seedling will become “leggy” as it grows towards the light.

Keep the light source close to the seedlings.

At this stage the seedlings are very fragile. When you need to add water, add it between the pellets. The flow of water can actually displace the seedling and/or damage the stem. Also watering from the bottom will help your roots grow longer. You want to avoid diseases such as damping off, so let the seedlings dry out before re-watering.

Fungus is your enemy here.

As the seedlings put on a few true leaves, they will outgrow the pellet and will need to be repotted in a larger pot with soil. After repotting you can keep them under the lights until the weather cooperates for transplanting in the garden.

As the seedlings get closer to that point, run your hand across the plants moving the stems slightly. The goal is to toughen the stems a bit so that they will be able to handle wind outdoors.

These seedlings are a bit leggy but they can still be good producers. Hardening-off is an important step.

When the weather is ready for transplanting you will need to harden off the transplants. If you take plants that have been living in a cozy, protected environment and move them into a place with full sun and wind they will suffer. You can avoid this by moving them out slowly. The first few days place them outside in the shade just for the day. Next, put them outside in the shade for the day and night. Then move them into full sun for a few hours. Finally, they are ready to be put in the ground. This type of hardening-off is the ideal way. You may not have all the time for all of these stages, but do the best you can. Your plants will reward you!

Indoor Seed Starting – Part Two

All of this rain has me very excited about getting back to our seed starting project.

I have one note about seed starting media. If you choose to purchase bagged media for starting seeds indoors, do not choose something with fertilizer in the mix. This will be too strong for seedlings. There are plenty of bagged mixes specifically for seed starting so choose one of those.

We are ready to expand our pellets. Notice the seed pellets are fully expanded with no standing water:

Seed pellets are not too wet but moist all the way through.

Next, take a fork and open up the top a bit and fluff the media. I like to take this time to make sure that the moisture is uniform all the way through with no dry spots:

Fluff the planting media with a fork to ensure uniform moisture.

Now you are ready to plant your seeds. If you are mixing seed types in one tray, make sure that they will emerge and grow at about the same rate. I like to use plastic forceps to exactly place the seed where I want them. Some seeds, like lettuce and herbs, are very small and easily lost in the tray. Know how deeply to plant the seeds. Most of the ones you will probably plant just need to be lightly covered with the planting media.

Plastic forceps can be your best friend!

It is worth the effort to do some research on your seed types. For example, cilantro seeds don’t germinate easily when exposed directly to light. Also, there are some seeds that just do better planting directly into the soil, beans and corn are good examples.

At this point it is a great idea to label your seed tray. Sharpie markers on masking tape work well. The tape sticks to the tray but can be removed later. Do not be tempted to label the lid. You will be removing the lid later and you don’t want to forget the original orientation. Finally, put the lid on the tray, making sure it fits tightly.

Do not forget to label your seed trays.

Do not place your seed tray near a window and hope for the best. You will be disappointed. You will not get enough light for healthy seedlings and the temperature fluctuation at the window will be problematic.

Use a light system. The system does not have to be complicated. I have a light fixture with florescent bulbs attached to a structure with moveable chains. This setup was originally housed in a bathroom tub but it is now in my grown daughter’s bedroom. Very simple. You need the chain to move the light so it stays just above the seed tray. To produce robust seedlings you need the light no more than an inch or two above the tray. This will be imperative as the seeds germinate and grow.

If you are germinating seeds in a place that is reasonably warm you do not need a heating mat. Those were designed for outside greenhouses and places like Michigan. By using a heating mat when you don’t need one, you risk drying out your planting media.

So far this is pretty simple, right? If you have any questions or concerns you can comment or email me at beckygri@uga.edu. Send photos! Next week we will discuss seedling care.

Happy Seed Starting!

Indoor Seed Starting – Part One

Over the next few weeks we are going to talk about seed starting. I did three in-depth posts last year and I am going to rerun them this year by request. Spring is coming….

Just flipping through one garden seed catalog I found 89 varieties of tomatoes, 21 varieties of cucumbers, 20 varieties of eggplant and 26 varieties of sweet peppers, including three types of lunchbox peppers. Compare that to the different types of vegetable plants that you would find at your big box retail store. Add some variety to your life and try starting your own seeds!

The rule of thumb is to start your warm-season seeds 6-8 weeks before planting time so over the next weeks we are going to explore indoor seed starting in-depth. For beginners, follow along with me as you start your first seeds. For seasoned seed-starting veterans, you may pick up a trick or two. I also encourage you to share your experience through the comments.

Let me begin by writing that there are many effective ways to start seeds indoors. I am going to share with you the way that I like to do it. I have been starting seeds indoors for decades and I have found a way that works best for me. You may find a different way that works best for you and that is terrific. I look forward to learning from you all as well.

To start, I like these re-useable plastic trays. They are easy to store and come in many sizes. I have friends who save their old plastic milk jugs and trim them down for seed starting; that works well for them.

These trays are easy to use for seed starting.

Any plastic trays MUST be disinfected before adding soil media and seed. I use a solution of 9-parts water to 1-part bleach. This step is important to eliminate any pathogens that have been overwintering on remaining soil particles. Starting with clean trays is an important step towards healthy seedlings. Don’t skip it.

These soil particles could hold pathogens. Disinfect those trays!

I like to use the peat moss discs for my planting media. As a bonus, the peat moss contains properties that discourage fungal growth. This helps prevent the disease damping off which is a real problem for seedlings.

The pellets expand with the addition of water.

These pellets are readily available and are easy to store. Add water and the pellets expand. I use warm water to create a favorable environment for the seeds. It is important here to not oversaturate the discs with too much water. Too dry is better for the seeds than too wet. Too wet means that the seeds could rot or disease will become a problem. You want the planting media to be just damp. If you can wring water out of the media, it is too wet. If this happens you can let the discs sit outside the tray for a few hours so that they can dry out a bit. You will get the hang of how much is too much as you practice.

Okay, gather your seed starting equipment, and play around with the pellets. Next week we will talk about planting the seeds.

Trying Something New in the Georgia Community Garden – Corn

Today we continue our series on a good replacement for tomatoes in our summer community garden plots. Today’s crop to consider is corn.

Usually corn is avoided in the community garden. The tall stalks shade other plants, there is not much yield in the amount you can grow in a small space, and corn takes a large amount of water. That being said, I sometimes find community gardeners who really want to grow their own corn. They remember eating corn fresh from a grandparent’s farm or working the corn patch with their parents. Often these gardeners are now city dwellers and the corn means a great deal to them.

Corn tassels waiting on wind to spread the pollen

Instead of totally abandoning the idea of growing corn, why not think about trying some of the short growing varieties? Several of the seed companies offer shorter varieties. Burpee advertises a corn for growing in a patio container called On-Deck Hybrid. The description of this type states that it grows 4 – 5 feet high. Compare that to Silver Queen which stretches 8 feet tall.

Park Seed offers a shorter variety called Early Sunglow Hybrid. Stalks from this corn are expected to top at 4 feet. Another thought is popcorn. Seed Savers offers Tom Thumb popcorn which grows only 3-4 feet tall. I have grown popcorn many times. It is fun to grow and fun to pop with children or grandchildren.

I will caution you that more than a few stalks need to be grown to get any kind of yield. Many stalks yield 1-2 corn ears per plant. If you are serious about trying corn in the community garden consider allocating at least half of your 4’X 8′ garden bed for the crop. Also, remember that the crop is wind pollinated. It does not hurt to shake those corn tassels yourself to make sure the pollen moves around.

Happy Gardening!
