There seems to be a lot of interest in being sustainable and saving seeds is one way to be food sustainable. Should you save seeds from your garden? When it comes to peppers and a number of other vegetables in your garden…it depends.
Wakulla Master Gardener Bill Osborne shows off some of the peppers he grew.
Hybrid vs. Open-pollinated
If you plan to save seed from your peppers, you first need to determine whether you planted open pollinated or hybrid peppers. Hybrid varieties are produced from two distinct pepper varieties and are often designated by “F1” appearing after the variety name. The seed from hybrid varieties is not usually saved because it does not produce plants and fruit that are true to the original variety. Open-pollinated varieties are developed from inbreeding plants for multiple generations to develop a stable genetic make-up. Seeds saved from these varieties will produce plants and fruit that are true to type.
How to Save Seed
To save seed of a known variety, it is important to isolate flowers or plants to ensure cross pollination from other varieties does not occur. There are four common ways to isolate flower/plants.
- Isolate plants from pollinizer insects by growing them indoors or in a greenhouse.
- Cover individual plants with insect exclusion netting.
- Separate different varieties by at least 400 feet.
- Put a small bag over an emerging flower until it has self-pollinated. Then remove the bag for fruit development.
The options above will help ensure your plants produce seed true to type. A fun experiment would be to save seed from plants/fruit that are not isolated and planted near other pepper varieties. There are endless possibilities on the peppers your new varieties would produce and you may end up developing your own named cultivar. You could also choose one of the isolation techniques listed to selectively cross different pepper plants. One misconception about growing peppers is that hot peppers planted near sweet peppers will influence the flavor of the sweet peppers. As you may have gathered from the information about crossing varieties, the flavor of the next generation will be influenced by hot and sweet pepper being allowed to cross pollinate.

Harvesting and Processing Seed
Peppers should be allowed to mature before seed is harvested. In fact, germination rates are higher when peppers are allowed to dry for at least one month before seeds are harvested. Make sure that no mold or disease is on the peppers, because this could affect germination rates. To harvest the seeds, simply remove them from the pepper and remove any flesh from the pepper. If the seed was harvested from fresh peppers, rinse the seed thoroughly and allow to dry before placing in a sealable bag or container. If the peppers were allowed to dry before seed harvest, then the rinse step can probably be skipped. Store the seed in a cool, dark, and dry location such as a refrigerator.

As fall begins we often begin to think about the successes and failures of our vegetable gardens. Two of my successes this past summer have been pepper and basil.
A variety of peppers work great as transplants in mid to late spring. This spring a large variety of peppers were planted including Cayenne, Bell, Cubanelle, Habanero, Poblano, Anaheim, Cajun Belle, Havasau, Serrano, Jalapeno, and Banana. A loose, rich media was used containing coconut coir and composted organic humus to provide an excellent well-drained location which also retained moisture. Finding this delicate balance is difficult but can be achieved by using coconut coir and organic matter based garden soil mixtures. After the peppers were planted, they were side-dressed twice with a standard bagged 8-8-8 fertilizer blend containing micronutrients and once with an organic fertilizer. During the heat of the summer it was important to water the peppers at least every other day. Need for watering decreased as the fall weather approached, but was still necessary.

In fall, many gardeners think it might be a good time to remove their peppers plants, but they can be encouraged to produce peppers until frost and maybe a little later with protection. Oftentimes it is more practical to start or transplant new pepper plants the following spring, but it is possible to pot up and overwinter peppers in a sheltered area or greenhouse.
In addition to peppers, basil was especially bountiful this year. To save my basil bounty for the winter I have options to dry, blanch or make pesto. This should be done before the first frost, since basil is very sensitive to freezing temperatures. Other herbs that will usually overwinter well in the garden include thyme, chives and rosemary. They will need little to no protection. Additionally, sage might come back the following year if it is in a protected area. Herbs such as cilantro and parsley will thrive in our North Florida winters and should be planted now.
To preserve the bounty of your harvest for later use, you may can, pickle, or freeze peppers. Follow these USDA-approved guidelines from the National Center for Home Food Preservation:

Yes, that’s right! We made it through the hottest part of the year and we are looking ahead to fall just around the corner! I am excited to be discussing September and what we can do to prepare for fall in the garden. As the nighttime temperatures start to cool down, we are given many more options.
For annual color plantings in September, try Ageratum, Celosia, Zinnias, and Wax Begonia to add fall color to your landscape. Bulbs will also add color, texture, and pattern to a bed. If you have some extra space, a variety of elephant ears could really accent a bed or you could always go with the classic calla, narcissus or zephyr lily. Popular vegetables to plant in North Florida in September are broccoli, carrot, cabbage, and collards. See Vegetable Gardening in Florida This is also the time of year to establish strawberry plants. Some great herbs to get started are Mexican tarragon, mint, rosemary, and basil.

There are many things that can be done in your lawn during September. Monitoring your lawn for its health and potential insect pests is important this time of year. Common insects to scout for are fall armyworms, chinch bugs, mole crickets, and sod webworms. The last fertilizer application should be done by the middle to end of September. Make sure you choose a fertilizer with little to no phosphorus unless a soil test shows differently. To maintain a healthy lawn, avoid weed and feed products and only apply herbicides in areas with high infestations of weeds. Weed and feed products are not recommended because the timing of when to fertilize and the timing of the weed killer is not always the same. The best management practice is to use a separate treatment for weeds and when possible spot treat weeds.
If you already have bulbs in your landscape from previous growing seasons, this is the time to divide and replant those that are big. You can also add organic matter to new planting areas. Continue working on your vegetable plants and prepare them for either transplants for a fast start, or plants seeds for more variety. Throughout your landscape, it is important that plants are getting the right amount of water as we go in and out of wet and dry weather this time of year.
October will be here before we know it in just a couple of weeks. Look out for the next article to come. We will be getting into the cooler nights and more options for planting vegetables and herbs!

Carrots need enough space so as not to compete for light, nutrients, or moisture. Photo by Full Earth Farm.
Of all the garden veggies, carrots are very close to the top of my list of favorites to grow. They can be directly seeded into the garden, need no pruning or staking, can hold up magnificently in the cold, have few pest problems, are easy to harvest, can be eaten raw or cooked, and they are, of course, delicious.
Hand-seeding carrots can be a challenge, as the seeds are very small. Photo by Molly Jameson.
Carrots are in the Apiaceae, or umbel family, along with cilantro, celery, fennel, parsley, and dill. Flowers in the umbel family grow as short flower stalks which spread from one point, like that of an upside-down umbrella, hence their name. If the carrot root is not harvested, the plant will produce beautiful umbrella-like inflorescences the following year, as carrots are biennial.
When planting carrots, there are some important aspects to keep in mind. Here in Florida, carrots thrive in our cool season. They prefer soil temperatures to be less than 80°F for good germination and air temperatures below 75°F for best growth. Therefore, waiting until mid-September through October to seed will yield better germination and growth.
One of the biggest mistakes one can make in the garden is neglecting to thin seedlings. And carrots – whose seeds are a mere millimeter in length – are one of the prime culprits.
An individual carrot needs one to three inches of soil space, depending on the variety, to grow to full maturity and not compete for light, nutrients, or moisture. This, however, does not mean that you must only plant one carrot seed per one to three inches. In fact, carrots should be seeded one-half inch apart, especially when day temperatures are above 75°F, as you may have spotty germination. But the key is proper thinning. Carrots take between seven to 21 days to germinate, so be sure to give them time, and be sure to keep the area consistently moist, but not water-logged.
Depending on the variety, carrots need one to three inches per plant. Photo by Beth Bolles.
Once germinated, it is crucial to make your first thinning. Find the seedlings that are less than an inch apart and simply cut their stems at the soil line using either a sharp fingernail or garden sheers. Depending on the variety of carrot and seeding density, you may need to make another thinning to ensure the carrots have enough room to prosper.
I know it can be emotionally challenging to remove growing seedlings from your garden – but remember – it’s for the greater carrot good!

The hottest days of the summer are here and you might be thinking, “There is no way something could survive this heat!”. You might also be wondering “What can I do in my landscape?” Well, you are correct – it is hot and there are not many plants that thrive in this type of weather, but the good news is we are at the end of the summer season and there are things we can begin to do to get ready for fall. It’s not too late to get the last of the summer vegetables going such as lima beans, cucumbers, eggplants, and peppers. Many cool season crops can also be planted by seed now and tomatoes will thrive going into the fall season. See Vegetable Gardening in Florida
There are some heat-tolerant annuals like vinca, gaillardia, bulbine, and coleus that can be planted now in the landscape. See Annuals. Any time of the year, even late summer, bulbs like Aztec Lily, Butterfly Lily, Walking Iris, and Spider Lily can be planted. See Bulbs for Florida. Not many herbs do well in our Florida sun this time of year, but Bay Laurel, Ginger, Mexican Tarragon, and Rosemary can be planted as transplants now but not as seeds just yet. See Herbs.
August and late summer is the time of year that you may be seeing damage in your lawns. This could be caused by insects, disease, or irrigation failure. It is important to determine the cause, so the proper remedy is used. Some ways to avoid lawn damage are checking your mower blades regularly and making sure they are sharp. Also only cut the top one third of the blade of grass to not stress it in the heat of the day. It is good practice to test your irrigation clock and have a rain sensor. Some municipalities in north Florida prohibit the application of fertilizer during the summer rainy season from June to September so check with your local extension office. See Insect Management in Your Florida Lawn

There are some other maintenance measures you can take in August to help your landscape and prepare for the fall season. If older palm fronds are yellowing, this could indicate a deficiency in magnesium or potassium. Talk to your local agent or visit your local store for an appropriate palm fertilizer. See Palm Nutrition and Fertilization. Are you holding on to those beautiful fall mums or decorative Christmas poinsettias? Now is the time to pinch them back to allow time for buds to set for winter blooms. Finally, it is a good time to deadhead (remove old blooms) and fertilize flowering annuals and perennials. We’ve had substantial rain this summer, so keep in mind that the soil could be lacking nutrients. A soil test can give you data that indicates what you need for the up-and-coming growing season.
