You’ve grown some wonderful vegetables, annuals or perennials and you would like to save some of the seed from those plants to have for planting in the future. This is a great way to get more of the plants you know and love while saving on the expense of new plants. One exception are plants that are F1 hybrids; seeds from these plants will produce crops quite dissimilar to the parent.
First, you need to collect ripe seed from the desired plants. How do you know when the seeds are ripe and ready to harvest? The strategies for annuals/perennials and vegetable plants differ.

For annuals and perennials that flower without making a fruit, wait until the flower has dried up and the seed head is brown and dead-looking. The seeds are then mature and ready to harvest. Take a look at the photo of the coneflower seedhead for reference. These seeds are already dry and can be put into an envelope and then into a sealed jar or plastic stage bag that contains a desiccant to absorb any excess moisture. There are a few options for desiccants: the little packets that come in vitamin bottles and purses to keep them dry, cornmeal or dried milk in bottom of the bag. Be sure to label your envelope with the date and name of your plant seeds. Store in the refrigerator.
When you are saving seed from a vegetable that has seeds inside it such as a tomato, pepper or squash, harvest the vegetable when it is ripe and ready to eat and scoop out the seeds and wash away all other plant parts from the seed. These seeds are very moist and if stored in this state, they will rot into a mess. You want to get the moisture content below about 8% for long term storage. There are several methods:
- If the humidity is low and the temperature high, (I know, those can be rare conditions for Florida) you can put the seeds in a single layer on a baking sheet in the shade to let them dry all day.
- Another option is to take that baking sheet with a single layer of seeds and put it in a 100° oven for 6 hours with the door open. It’s crucial to monitor your oven temperatures as those above 100° will kill the seeds.
Once the seeds are dried sufficiently, store them as described above for flower seeds. Your seeds can then last for several years.

What if I told you there was a way to create compost indoors? No pitchfork required, no hot steamy temperatures, a simple mix of ingredients, and it would fit right under your kitchen sink? As long as you can convince your family to have worms in the house… you can start vermicomposting.
Vermicomposting uses a type of worm called red wigglers. These worms specialize in digesting organic matter, can digest their own body weight in food each day, and can double their population within months. It is, therefore, a wonderful way to responsibly dispose of food waste and can reduce your garbage by more than a third. Microorganisms inside the worms are actually doing most of the work, and the “castings” excreted are teaming with beneficial microbes and nutrients that will condition your soil and make the plants in your garden shine.
You can easily construct a vermicompost bin at home, but you can also purchase one online. Bins should hold about five gallons for one to two people or ten gallons for three to four (Rubbermaid containers work nicely). Your container should not exceed 12 inches in depth, as red wigglers do not like to burrow deeply. You will also want good aeration, so drill holes in the bottom of the bin and either place the bin in another container or put the bin on bricks and use a tray underneath to capture escaped materials. Either way, you will want a lid – as worms do not like light and need moisture – but they also need to breathe, so make sure it is not airtight. Be sure your bin is never in direct sunlight or in a location that regularly exceeds 80°F.
To get started, you will need about 1,000 worms, which weighs about one pound. Red wigglers can also be purchased online, at local nurseries, and some bait shops. Better yet – if you know vermicompost enthusiasts, they may be happy to share.
Before you purchase your worms, you want to prepare your worm bedding. Shredded newspaper and coconut fiber (coir) – which you can find at your local nursery – work great. You will also need to add a small scoop of garden soil to inoculate your bin with microbes. To get started, lightly moisten your bedding material and fill your bin about two-thirds full.

Now it is time to add the food. Worms love vegetable scraps, most fruits, moldy bread, coffee filters and grounds, tea bags, and crushed eggshells. Chop their food into small pieces for fastest consumption. Foods to avoid include meat, dairy, large amount of citrus, and onion peels. Start out slow, and put the chopped food in the corner of your worm bin. Once your worms are settled, maintain the bin as half bedding, half food scraps. If your bin looks too dry, add more food. If your bin looks too wet, add more bedding or hold back on food a few days. Bad odors will develop only if the worms are overfed.
Give your worm bin about three to four months, and then you can begin to harvest. Add a handful of castings to potting mix or a thin layer directly to your garden. Give vermicomposting a try – your plants will thank you, your trash will not stink, and you will reduce your global impact.

As the days get shorter and temperatures decrease, it is time install your cool season vegetable garden. Many vegetables can be grown in Florida, but it is important to understand what the climatic requirements are for each crop to have the most success.
To get the most of your garden space know the recommended months for planting and the turnaround time for harvest so that you can stagger plantings or change out crops as needed.
September is the ideal time to plant cabbage, beets, kale, lettuce, mustard greens, onions, and radishes. After the New Year some options include eggplant, potatoes, English peas, and turnips.
Many gardeners start their tomatoes and peppers as early as February, but they are frost sensitive and early planting carries some risk of cold damage.
If you are interested in learning more about fall vegetable gardening, join the UF/IFAS Bay County Master Gardeners on Friday, September 18th for a free vegetable gardening workshop. This class will be held at the Bay County Extension Office at 2728 E. 14th Street in Panama City. To register please call 850-784-6105 or email bay@ifas.ufl.edu. Fall-VegMG2015

Mushrooms are an excellent low calorie food with a high fullness factor (they fill you up). But the “common” or “button” mushroom lacks natural flavor. On the other hand, shiitake mushrooms have all the benefits of button mushrooms, but offer a flavor punch and a higher fiber content. However, they are a bit more expensive. Wouldn’t it be great if you could grow mushrooms in the home garden? Growing mushrooms may be easier than you think.
Mushrooms are fungi that grow on rotting organic matter. Shiitake mushrooms are best grown on hardwood logs. Oak logs are generally used for a mushroom food source, but sweetgum, red maple, and poplar can also be used. Logs ranging from a diameter of 2” to 7” and 3’ to 4’ long are recommended. Once the logs have been cut to size, the fungus inoculation process can begin. Holes are drilled into the log and the spawn are inserted. Spawn is a fancy name for the mixture of mushroom roots (mycelium) and a growing substrate (usually made up of compacted sawdust or a wooden dowel). The plugged holes are sealed with wax. The inoculated logs should be placed in a cool, moist, well ventilated place. It can take anywhere from 6 to 18 months for the mycelium to inhabit the logs. This process is called “spawn run” or “incubation”. Mushrooms grow best within a temperature range of 50-70°F, so the fruiting process is a spring or fall event.

The recommended mushroom strains for Florida are: CS-41; CS-15; CS-24; CS-125; CS-16; CS-11; and CS-118. Favorable conditions are strain-specific, so please do some research before purchasing strains. A list of supply dealers can be found at the North American Mycological Society webpage.
Mushroom production is a fun activity, but it is extremely labor intensive. This article is just a brief summary of process. For more information on producing your own mushrooms, please visit the UF/IFAS Small Farms Mushroom Production webpage. Mushroom production is not a recommended business venture for Florida, but can be a fun hobby.

As our world and our lives become more centered on technology it seems that all the information we need is just a touch screen away. After all, you are most likely reading this article from a laptop, smart phone, or tablet. While convenient and portable, there are some places you might not wish to take your electronics and one of those places is in the garden. You may say, “Well Taylor, that’s what they make waterproof, shatterproof, dirt proof, etc. cases for!” and I would say that you’re right. However, technology has many limiting factors such as battery life and screen glare. Now believe me, I am by no means disparaging technology! I come from a generation that considers Wi-Fi as necessary as water and an outlet comparable to oxygen. But there is something to be said for having a book in hand when out in the garden. For one thing your neighbors won’t worry about you as they see you march around the garden with your phone in the air doing the “No Signal Dance”. Also, a book is great to have in order for you to jot down any notes or reflections. I would like to list for you a few books that I often reference when I receive calls from homeowners. These books will cover various topics and all of them can be found on the UF/IFAS Bookstore website, the links for each can be found below. If you have any questions contact your local Extension Office and, as always, feel free to contact me and I can give you a rundown on my collection of favorite reference books!
