Fall is the season for leaf color changes on many plants, but we are often concerned when we see evergreen plants with brown leaves. Learn what is normal browning for evergreens and when to seek more help from UF IFAS Extension Escambia County.
As you garden this fall, check out the North Florida Vegetable Gardening Guide, compiled by UF/IFAS Leon County Extension.
Getting into vegetable gardening, but don’t know where to start?
Even experienced gardeners know there’s always more to learn. To help both beginners and advanced gardeners find answers to their questions, the UF/IFAS Leon County Extension Office put together the North Florida Vegetable Gardening Guide. It incorporates multiple resources, including articles, planting calendars, photos, and UF/IFAS EDIS publications.
The North Florida Vegetable Gardening Guide covers the many aspects of vegetable gardening, including how to get started, site selection, insects and biodiversity in the garden, soil testing, composting, cover crops in the garden, irrigation, and more.
You can click here to view the digital version of the guidebook. We also have physical copies of the guide available at the UF/IFAS Leon County Extension Office (615 Paul Russell Rd., Tallahassee, FL 32301).
As October gets by us and November quickly approaches, I would like to include the preparation on What to Plant? And What to Do? Some great annual plant choices are digitalis (foxglove), petunias, and Shasta daisy. There are many daffodil bulb varieties for North Florida including the following: Carlton, Fortune, Silver Charms, Thalia, and Sweetness. We will be getting into more of the cooler days, so this is a good time to start bulb onions and salad crops such as arugula, lettuce, and spinach. Dill, fennel, oregano, and sage are all herbs that can be planted throughout the fall months.
Start preparing now so your fall garden will be full of dark leafy greens, multi-colored lettuces, and root vegetables of all shapes and sizes. Photo by Molly Jameson.
In lawns there are a few key things that can be done in October. It is possible to control winter weeds before they appear. This is the time to use preemergent herbicides when nighttime temperatures are between 55-60 degrees Fahrenheit for four to five days in a row. If a green lawn is desired, you can overseed with annual ryegrass when the daytime temperatures are in the low 70s. Remember, the lawn will still need to be watered and mowed to maintain a healthy ryegrass. Watch for fungus like brown patch and large patch disease. This can become active when the soil temperature is between 65-75 degrees Fahrenheit.

And last but not least as you prepare for winter around the corner you can plant evergreen hollies that will make it through the cold and provide a splash of color with red berries. Gather pine needles that are dropping and use as a natural mulch, and this is the last month that strawberry plants can be established in a bed or a large container.
There are some key practices that are necessary to make sure your trees and shrubs establish and thrive in your landscape. Learn a few pointers from UF IFAS Extension Escambia County to promote healthy establishment after correct plant installation.

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.
