Fall Gardening Spotlight: Collard Greens
When cooler weather finally rolls into the Panhandle, collard greens (Brassica oleracea var. acephala) are one of the most reliable crops you can grow. Members of the cabbage family, Brassicaceae, collards are hardy, low-maintenance, and don’t mind a little frost – in fact, a nip of cold will sweeten their flavor. In my neighborhood, it’s not unusual to see collards thriving in gardens all the way through winter and early spring.
Collard seeds can be directly sown starting in late August, with transplants best set out from September through November. If you start from seed, expect to harvest in two to three months. For a quicker turnaround, grab transplants from a local nursery and you’ll be cooking collards by Thanksgiving.
When late summer and early fall heat lingers, young plants may need a little extra care. Providing afternoon shade with a 40 to 50% density shade cloth can keep seedlings from wilting and help them establish more smoothly during warm spells in September. Regular, even watering is also important, but make sure the soil drains well.

Space plants 12 to 18 inches apart in rows two to three feet wide, since collards grow large and need room to spread. In raised beds, you can space plants the same 12 to 18 inches apart in all directions, often in a staggered grid, to make the most of the space. For a steady supply, consider staggering plantings every couple of weeks through early November. Collards are among the more forgiving fall crops – just give them at least six hours of sun, nutrient-rich soil, and steady moisture.
One thing I’ve learned from experience: don’t be shy about picking leaves. Collards will keep producing as long as you harvest from the bottom up, leaving the center growing tip alone. I’ve found the leaves taste best when they’re picked young, around 10 to 12 inches long. If you leave them on longer, they’ll toughen up a bit but hold up well in slow-cooked dishes. Even a short row in the garden can keep a family in collards for much of the season, which helps explain why they’ve been a fixture in Southern kitchens for generations.
Some varieties that do well in our area include several open-pollinated classics. ‘Georgia Southern’ has stood the test of time for its tender, large leaves, while ‘Vates’ is another reliable option, known for its compact size and resistance to bolting. For a collard that’s as pretty as it is productive, try the heirloom ‘Alabama Blue.’ Its bluish leaves are streaked with purple, adding beauty to the garden as well as the plate. If you’d like to try hybrid varieties, look for ‘Champion,’ bred from ‘Vates’ with improved cold tolerance and disease resistance, or ‘Top Bunch,’ which grows quickly and recovers fast after harvest. You’ll usually find at least one or two of these on the racks at local plant nurseries.
While collards are tough, do keep an eye out for caterpillars such as cabbage loopers and diamondback moths, which can chew holes in the leaves. Picking them off by hand usually can keep them under control if you scout often, though a light spray of Bacillus thuringiensis (Bt) can also help if they get ahead of you. Be sure to follow the label directions carefully when applying.
Once you’ve got a basket full of collards, you can make them as simple or as dressed up as you like. I usually just sauté them in olive oil with garlic, salt, and a pinch of smoked paprika. They also slip nicely into soups, mix well with pasta, and can even be blended into green smoothies.
Collards are tough, productive, and delicious – and if you plant a few this fall, you might just find yourself sharing leaves with neighbors well into the new year.
It may still be scorching hot outside, but it’s not too early to be thinking ahead of what to plant in your fall garden this upcoming season. There’s much to do to prepare, so knowing the right steps to get ahead will save you time. There are many options for fall and winter vegetables to grow in the Florida Panhandle and picking what is best for you or your family is essential.
The first step when planning a fall garden is to clean all debris from your previous plantings to prevent disease. The next would be to take a soil test. It’s essential to know the nutrients existing in the soil to have a successful growing season and thriving plants. You can contact your local extension office about soil testing availability in your area. Once you know the nutrient levels of your soil in your garden, you can make applicable amendments, such as adding compost. Some people opt to grow a cover crop in between growing seasons.

It’s important to know what vegetables grow best at specific times of the year. Most vegetable plants grown in the fall are considered “hardy” or semi-hardy.” A plant’s hardiness determines their level of cold tolerance. While it stays relatively warm in the fall here in North Florida, it is important to understand the lowest temperature a vegetable plant can withstand. You should also know your USDA Hardiness Zone. As of 2023, the Florida Panhandle is considered 9A under the USDA Hardiness Zone map.
Many fall vegetables can be sewn directly into the ground. Some examples of fall vegetables are leafy greens like lettuce, kale, and swiss chard. There are other vegetables in the brassica family that thrive in the fall like broccoli, cauliflower, and brussels sprouts. To get more ideas of what to plant when, refer to the Florida Panhandle Planting Guide

Even though it’s still 98 degrees outside, it’s the time of the year to be looking ahead to plan a fall garden. With the optimal climate of Northwest Florida, the fall season offers gardeners a time to refresh their plots and prepare for another productive season. Here’s a guide to make the most of the fall gardening season!
Site Prep for Fall Gardens
When transitioning from summer to fall, it is important to prep the area where a new crop will be placed. It’s best to remove all dead material from your spring garden so it will not spread disease or bacteria to the new plants. You also may consider adding nutrients to the soil after it has been tilled for fall vegetables. The best method to know how much to add into the soil is by first taking a soil sample. The soil sample results will show what is readily available for vegetables going in the ground and will give you a baseline of how much fertilizer or organic amendments to add. The fall season is also one of the best times of the year to prioritize soil health. Another way to do this in the off season is to incorporate a cover crop into your gardening regimen.

What Vegetables Do I Plant in the Fall?
The “cool” temperatures of a Florida fall make it very ideal for a variety of cool-season vegetables. Vegetables can be classified a hardy, semi-hardy, and tender based on their abilities to withstand freeze conditions, cold temperatures, or high heat. That is how can put vegetables in warm-season and cool-season groups. Tender vegetables are considered short season and are typically seen in spring and summer months. Examples of tender vegetables are potatoes, tomatoes, and squash. Semi-hardy vegetables are mostly frost-tolerant but cannot withstand freezing temperatures. Examples are carrots, leafy greens like Swiss chard and Bok Choy, peas such as sugar snaps, and celery. Lastly, hardy vegetables are a true cool-season vegetable that is frost-tolerant and can withstand freezing temperatures up to a certain degree. Examples of hardy vegetables are broccoli, cauliflower, kale, onions, and garlic.

Fall Garden Maintenance
With the temperatures being cooler in the fall months, your garden vegetables will require less water. It is best to water your garden early in the morning to allow the soil to dry out during the day. Doing this will prevent fungal growth and root rot. Utilizing mulch will also help conserve soil moisture, regulate the soil the temperature from the cool weather, and suppress weeds. Even through the winters are typically mild in Florida, it is still best to have a freeze protection plan for your garden. Using row covers or frost blankets will help shield your garden when the temperatures drop.
As you enjoy your fall garden, planning ahead for winter and spring will also set you up for success. Research what crops will follow best behind your fall harvest and consider starting your seeds indoors to get a head start. By embracing these fall gardening tips, you can enjoy a bountiful harvest and a thriving garden throughout the season. Happy Fall!
The long summer days are beginning to wane, the mercury is starting its slow march down the thermometer, and your landscape displays all the signs of winter. It’s the time of year that many gardeners dread. Fear not, my fellow parishioners of the soil. I’m here to tell you that there is hope for your landscape. With a little planning, your home can remain beautiful as there are blooms aplenty even into the autumn months here in Florida.
Deciduous Trees
Established deciduous landscape plants begin their annual cycle by sloughing off their leaves, but this doesn’t mean they have no value. After months of standing boldly in your yard, many begin to lose their chlorophyll and turn eye-catching hues of orange and purple. Trees such as bald cypress (Taxodium distichum) create a fantastic fall display as they march into winter slumber. Maples (Acer spp.) will similarly provide a beautiful show once the cold weather hits. Plant these trees in your landscape while observing the “right plant, right place” philosophy and you will provide a low-maintenance pallet of annual colors for decades.

Perpetual Perennials
Next, perennial plants are the lynchpin in many landscapes, filling in the space between your trees and inground annuals. Choosing those with bright, warm colors will make your yard stand out against your neighbors. Remember, when planting, some plants will not survive the first frost. One plant prone to this style of dieback is fire spike (Odontonema strictum). Here, you will find bright red blooms underpinned by large, striking green leaves. Don’t be dissuaded by the frost-tender nature of this plant, it is an excellent specimen and supports pollinators later into the season. Salvia (Salvia spp.) is another superb specimen for some color later in the season. This again will die off upon the first frost but, until then, will provide bright flowers with grey-green foliage that is striking in any garden. For those seeking an evergreen autumn bloomer, look no further than the leopard plant (Farfugium japonicum). This sometimes overlooked and shade-loving member of the aster family provides yellow flowers through the fall and unique round leaves throughout the rest of the year.

Annuals for Brilliant Color
Finally, let us peruse flowering annuals. The advantage here is the vibrant colors they bring, but they are short lived and will need to be rotated out in a few months. Sweet alyssum (Lobularia maritima) is a prime example of a versatile plant fitting this bill. They have a spreading habit, making them excellent as a cold weather ground cover or a beautiful trailing potted plant hung on your porch. If sprawling isn’t your cup of tea, investigate calendula (Calendula officinalis) for a splash of yellow in an upright ray-style flower. Remember that these cold weather annuals will not tolerate heat or humidity, so plant them in the fall when things cool off. They will do well in the ground directly or with a pot-in-pot system. The latter will allow easy switches should the plants begin to falter. If planted directly in-ground, prepare your site accordingly. Soil testing will dictate fertilization needs and adding organic matter will ensure adequate water retention.
