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 tweezers 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 tweezers 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

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.

Pest Alert: February Monitoring for Granulate Ambrosia Beetle

Post authored by Paul J. Pugliesea and Shimat V. Josephb

aUGA County Extension Agent/Coordinator (Bartow County), Cartersville, GA
bAssistant professor, Department of Entomology, University of Georgia – Griffin Campus.

Fig. 1 Adult beetle (left) and “tooth pick” symptom (right)

Granulate ambrosia beetleXylosandrus crassiusculus (Mot.) [Previously known as the Asian ambrosia beetle]

Introduction: Granulate ambrosia beetle (Fig. 1) is a serious pest of woody trees and shrubs in Georgia. These tiny beetles were first detected in South Carolina in the 1970’s and have spread across the southeastern US.

Host plants: Woody ornamental nursery plants and fruit trees are commonly affected. In spring or even in late winter (around mid-February), a large number of beetles can emerge and attack tree species, especially when they are young. Some highly susceptible tree species include Styrax, dogwood, redbud, maple, ornamental cherry, Japanese maple, crepe myrtle, pecan, peach, plum, persimmon, golden rain tree, sweet gum, Shumard oak, Chinese elm, magnolia, fig, and azalea.

Biology: The female beetles land on the bark of woody trees. Then, they bore through the soft wood and vascular tissues (xylem vessels and phloem) of the tree. They settle in the heartwood and begin making galleries. Eggs are laid in these galleries. Adults introduce a symbiotic fungi into the galleries as a food source for the developing larvae.

Symptoms: The initial sign of infestation is presence of boring dust pushing out of the bark as “tooth picks” (Fig. 1). Severely infested trees with granulate ambrosia beetle may show symptoms of stunting, delayed leaf emergence in spring, and extensive defoliation.

Fig. 2 Timing is a key factor in effectively managing Granulate ambrosia beetle. Monitoring traps placed in early February are useful for the early detection of beetle emergence and infestation.

Monitoring and management: Once adults of granulate ambrosia beetle bore through the bark, there are limited control options to mitigate the problem. Those settled beetles in the heartwood of the tree are less likely to be exposed to insecticides. Also, the beetles do not consume the wood, which further minimizes their pesticide exposure. Pyrethroid insecticides such as bifenthrin or permethrin can be used as preventative sprays to repel invading females. Thus, the insecticide-application timing becomes critically important for management. The insecticide applications can be timed with trap captures or adult activity. The simplest method to determine adult activity in the area is using alcohol and a bolt of wood (Fig. 2). A wood bolt (about 2 to 4-inches in diameter and 2-feet long) can be utilized. Any hardwood species such as maple will work for building traps. A half-inch diameter hole drilled at the center of the bolt, about a foot deep, is filled with alcohol and the opening can be closed using a stopper cork.  Ethyl alcohol or grain alcohol with 95-percent alcohol content (190-proof) can be found at most liquor stores. Hang several bolt traps along the woodland border of a nursery at waist height to determine beetle emergence and activity. Sawdust tooth picks (Fig. 2) begin to appear on the bolt when they are infested with adult beetles. Once tooth picks are detected on a bolt trap, daily scouting should occur on nearby trees.

An immediate spray using a pyrethroid insecticide on nursery trees is warranted upon detection of tooth picks on the bolt trap.  Be prepared and ready to act quickly as soon as beetle activity is confirmed.  If practical, the entire nursery should initially be treated with an area-wide application to repel beetle activity.  If individual trees are found to be infested, immediately destroy infested trees and follow up with targeted spray applications in blocks with beetle activity. Generally, pyrethroids are not effective for more than a week as their residues quickly breakdown. Re-application of the insecticide is generally required at weekly intervals until spring green-up is complete in areas where the beetle pressure is moderate to severe.

Healthy trees can withstand a low level of beetle infestation. Timely irrigation and adequate fertilization of trees throughout the growing season will increase a tree’s tolerance to beetle infestation.  Closely monitor traps throughout the spring for a second emergence of ambrosia beetles. Ambrosia beetles can have multiple generations throughout the year and are strongly attracted to trees that are drought stressed, injured, or excessively pruned.  Pay close attention to irrigation needs during extended summer and fall drought periods to minimize tree stresses.  Avoid mechanical wounding of trees with maintenance equipment that could invite ambrosia beetles to attack.    

When to deploy monitoring traps: The monitoring traps should be deployed starting the first week of February in Georgia because warmer periods during a mild winter may trigger early beetle emergence and infestation.

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!

Deciding on Raised Beds or In-Ground Gardening

Dr. David Berle and Robert Westerfield of UGA have created a series of publications on community/school gardens.  One of the most popular circulars is Raised Beds vs. In-Ground Gardens.  It is an excellent resource when determining whether or not raised beds would work for your garden.

The height of these beds is helpful for the senior gardeners at Tobie Grant Manor garden.
The height of these beds is helpful for the senior gardeners at Tobie Grant Manor garden.

Raised beds are defined as elevated boxes that are manageable in size and are filled with enough soil to support plants without using the soil underneath the box.  The height of the boxes can vary.  Tall boxes can be very beneficial to senior gardeners who are more comfortable working while standing instead of knelling down.  When dealing with native soil of questionable quality, raised beds with imported soil are an easy solution.

Some other advantages of raised beds are:

  • Prevention of soil compaction- raised boxes can limit foot traffic on the soil
  • Less weeding and maintenance
  • Reduced conflict – raised beds are very defined and easy to assign to participating gardeners
  • Better drainage
  • Extended garden area – raised beds can be placed on slopes, compacted soil, and even parking lots
The in-ground gardens at Woodstock Community Garden make it easy for a tiller to work the soil.
The in-ground gardens at Woodstock Community Garden make it easy for a tiller to work the soil.

There are advantages to in-ground gardens.  Raised bed materials can be costly for a garden group just starting and in-ground gardening can allow a tractor or tiller to easily help prepare the area.  Other advantages include:

  • Use of existing soil
  • Less permanent – if the landowner deems the garden temporary or for good crop rotation
  • Easier irrigation
  • Less start-up work
  • Clay soils do have benefits that are not found in man-made soils

As you start, or change, your garden carefully consider which arrangement will work for your group.  Consider your current and future needs and decide how much time and resources you all are willing to commit.  Your local UGA Extension office is a great resource for help.

The Magic of the New Year

Recently I attended a presentation given by a scientist who is known for her expertise in plant genetics. Her lab was one of the first to do work in what we now call genetically modified organisms (GMOs). Between the explanations of plant biochemistry and the future of our food system she snuck in a statement that was so profound it is worth sharing. She said, “plants are magic.” Yes, plants are magic.

One of my first memories involves plants. At about six years old, I received a science kit as a gift where seeds germinated in a substrate so that the grower could see the root radical and shoot as the seed sprouted. I was hooked. Plants were magic.

Basil seedlings

I have never lost that feeling of awe when dealing with gardens. Most of you are shaking your heads in agreement as you read this. The way flowers survive our droughts and our own mismanagement. The way a tiny seed pushes through our hard clay soil. How small seeds yield large amounts of food. You know it; plants are magic.

Savannah Trustess Garden

As we go into the new year and we are planning our 2018 gardens may we never lose that magic. I look forward to gardening with you in the next year.

Happy New Year!

Making Use of Seed Catalogs All Year Long

The seed catalogs have started arriving. In my household that is cause for excitement. I save them until I have time to properly enjoy looking through them. What do you do with your seed catalogs after you have looked through them and placed your orders? If you throw them into the recycling bin you are missing out as these gems are full of useful information.

If you are a school gardener, or a community gardener that works with youth, the seed catalogs can be used throughout the year! To start with you can laminate the beautiful photos to use as plant markers.

You can use the information provided in the catalog for lessons:

The seed spacing guide can be used for students to create a garden bed design.

The days to harvest information can be used for students to determine the planting dates of their garden design so that all the produce is ready at the same time.

The cost of the seed packages can be used to calculate the cost of the garden design.

All of this information can be used to calculate how much produce can be grown per square foot (inch, meter).

Students can look through the catalog and pick a vegetable they have never tried before.

Students could look through the catalog, find a favorite vegetable, and re-write the plant description.

Happy browsing!

Collard Greens Recipe from Mary Mac’s Tea Room

Collard Greens Recipe from Mary Mac's Tea Room

It seems many gardeners plan on preparing collard greens for their holiday tables and have asked that I re-run this post from 2014. Enjoy…

Community gardens all over Georgia are filled with beautiful, dark green collard greens. See the August 20th post on growing collard greens.  Once we get a few good frosts they will be ready to harvest.  Being such a Southern vegetable it is wonderful that the very Southern Mary Mac’s Tea Room in Atlanta has shared their famous collard green recipe.  Richard Golden is the Assistant General Manager and he says that the collards are his favorite of all the vegetables the restaurant serves.  Just in time for Thanksgiving this recipe is a real treat worthy of a special occasion.

Collard Greens Recipe from Mary Mac's Tea Room

Collard Greens

Collard Greens Recipe from Mary Mac's Tea Room
Very tasty with cornbread!

Serves 6-8

  • 2 1/2 pounds of collard greens, stalks removed and cut into 2 inch strips
  • 2 gallons of water
  • 6 ounces of fatback
  • 1 smoked ham hock
  • 1/3 cup bacon drippings
  • 1/8th cup salt

You should be able to find fatback and ham hocks at your local supermarket. Just ask the butcher if you have trouble finding them.

Collard Greens Recipe from Mary Mac's Tea Room

Wash the cut greens in cold water and 1/8th cup salt.  In a large stock pot, on high heat, boil the water, smoked ham hock, and fat back.  Let boil for an hour.  Add collards and bacon drippings to the pot.  Let come to a roaring boil and then reduce heat to medium.  Let cook for 40-45 minutes.  You may need to add additional water if the water starts to absorb past 1/3 of your original liquid.  Remove from heat and take out the fatback and ham hock.  Serve warm. Goes well with corn bread.

If you are not used to cooking with fatback or ham hocks, they are easily found at most grocery stores.  Just ask your butcher if you have trouble finding them.  Also, plan ahead so you can save your bacon drippings.  Your Grandmother would be proud, your fitness trainer not so much!

Mary Mac’s is such an Atlanta institution it was honored by the Georgia State House of Representatives with Resolution 477 declaring Mary Mac’s to be Atlanta’s Dining Room.  The menu includes fried okra, tomato pie, hoppin’ john, butter peas, and turnip greens.  All of these contain ingredients grown in Georgia!

Mary Mac’s opened in 1945 when Mary McKenzie wanted to use her cooking skills to make money in the aftermath of World War II.  In those days a woman couldn’t just open a restaurant but a “tea room” was acceptable.  The current owner, John Ferrell purchased the restaurant in 1994 and carries on the traditions.  Recently they catered Governor Nathan Deal’s birthday party.  If you decide to visit Midtown for a meal at Mary Mac’s, don’t forget the cobbler.  Trust me!

Making Your Own Applesauce for Hanukkah

If you serve potato latkes as part of your Hanukkah tradition why not try to make your own applesauce accompaniment? Many community gardens grow apples but if you don’t grow your own, there are plenty of fresh apples in Georgia to choose from.

Making applesauce is basic and according to the National Center for Food Home Preservation the apples you choose and the spices you add will make it your own special recipe. Select apples that are sweet, juicy, and crisp – very fresh. You can mix tart and sweet apples to get your desired taste.

The book So Easy to Preserve revised by Elizabeth Andress and Judy Harrison in 2014 gives great instructions on making applesauce. Wash, peel and core your apples. Put the apples slices in an 8-10 quart pot and add 1/2 cup water. Heat quickly, stirring occasionally, and cook until the apples are tender. This could be 5 to 20 minutes depending on apple age and variety. Press through a food mill or a sieve if you want a smooth sauce. At this point add any sugar and taste.

To preserve the applesauce, reheat sauce to boiling and pack into hot jars leaving 1/2 inch headspace. Remove air bubbles and wipe jar rims. Adjust lids and process in a boiling water bath.

For more information on food preservation contact your local UGA Cooperative Extension office.

Happy Hanukkah!
