The heat and humidity of August is upon us, the cool of fall seems very far away, but is it? Believe it or not, now is the time to start planning fall vegetable gardens.
One of the most popular fall vegetables throughout the lower southern states are greens. There are old stand-bys such as cabbage, mustard, turnip and collard, but also more novel selections such as kale, and rainbow Swiss chard. One technique to extend the cropping season of collards and kale, is harvesting only lower leaves while allowing plants to continue to grow, instead of harvesting entire plants. If several plants of each are planted, there will be enough for a family to have a continuous supply of greens through the season.
Most greens prefer a pH of 6.0 to 6.5, but will tolerate pH in the range of 5.5 to 7.0. If pH is too low, the rate of dolomitic per hundred square feet to raise pH one point is 2-3 lbs. Dolomitic lime must be added at least two months before planting to be effective. Greens may be fertilized with a variety of products from compost (at the rate of 20 lbs. per 100 sq. ft.) to 10-10-10 (at the rate of 2-3 lbs. per 100 sq. ft.) balanced fertilizer with micronutrients. Two to three light repeat applications in the soil at the leaf’s edge may be warranted if plants show a need.
Starting in late August, if the weather is not blisteringly hot, collards may be started by direct seeding. If hot days are excessive, it may be necessary to drop a shade cloth on young plants until weather cools. This will improve development in the event of extended heat in early September. It is also necessary to water regularly and thoroughly while making sure plants are well-drained.
In mid-September, kale, Swiss chard, turnip greens, mustard greens and cabbage may be planted. It is often an advantage to stagger plantings from September through December to extend the season.
Greens can be planted by either direct seeding or transplanting. I have found that if starting greens when it is still very warm, direct seeding is desirable since more transplant shock occurs when temperatures are higher. When it is cooler, transplanting may be more advantageous since the plants will be more developed and ready to harvest sooner.
Greens make a delightful addition to any meal so why not grow your own and experiment with novel types that cannot be found in store shelves. The video below details some novel techniques used to maximize greens’ harvest. Happy Gardening.

Growing up, as soon as I entered the fair gates, I always headed straight for the rides. If I was lucky, I was able to get an unlimited pass strapped around my wrist and didn’t need to worry about rationing any tickets. Although I usually didn’t remember the names of particular rides – they were clear in my imagination. The spaceship, the circular mini roller coaster, the alien arms… and of course, the Ferris wheel. It wasn’t until I was about a dozen rides in – and starting to feel a little queasy – that the fun houses and win-a-goldfish-by-throwing-a-ring or shoot-a-basketball-for-a-giant-stuffed-tiger games drew my attention. After that, I was ready for funnel cake. Maybe even a corn dog and an assortment of fried cheese, pickles, and the like. Inevitably, I would eat too much and be out of commission for any more rides I was hoping to squeeze in – or squeeze into! This is when I might finally make my rounds through one or two of the giant warehouse-looking buildings that lined the way to the exits, where I knew there was at least a llama or a goat to be fed at the petting zoo.

But when I started volunteering at the Leon County Animal Shelter as part of the 4-H Pet Partners at age 12, I was introduced to these buildings in a whole new light. We were assigned the task of creating papier-mâché cats and dogs to display at the fair to help build awareness of pet overpopulation. I remember my dog well – he was beagle-like, with long droopy paper ears and stiff pointy legs that I struggled to keep balanced. The day we went to set up our display, my adrenaline soared, as I knew our creations were to be judged and ribbons to be bestowed. Ever since, I no longer view the fair buildings as a last stop – rather, I relish my stroll through each of them, as they contain so many handmade treasures, many of which are adorned with blue rosettes of triumph.
The tradition of displaying and competing for the best quality handiworks at the fair goes all the way back to the Middle Ages and Renaissance, where merchants sold and traded agricultural goods that had been grown over the summer and freshly harvested in the fall. Naturally, competitions arose during these times, as they strove for the finest products.
Today, fairs reflect the personality of an area, and nearly universally include judges who inspect home grown fruits and vegetables, flowers, preserved foods, and baked goods entered into competition by the community. The North Florida Fair awards about $80,000 in cash prizes to citizens who create and grow various items. Anyone living within the 24 counties that comprise North Florida – from the Suwannee, west to the Alabama line – is eligible to enter as many of the exhibit categories as they would like.

The exhibits are arranged into various departments, such as Home Agriculture, Capital City Garden Club Flower Show, Poultry, Baked Goods, and Fine Arts and Crafts. Within each department, there are various classes that are split into certain age divisions (i.e., youth only) or experience levels (i.e., amateur vs. professional). Under the Home Agriculture department there are 42 classes, including 13 classes covering fresh vegetables. The Capital City Garden Club Flower Show department has 13 classes, including annuals, perennials, hanging baskets, fruiting shrubs, trees, and vines, succulents, and much more. If you would like to submit something you’ve grown, now is the time to begin planning, as this year’s fair is set for November 8-18.
All of the details for each department and class can be found on the North Florida Fair website (http://northfloridafair.com/), under the Exhibitors tab. Pay close attention to the application and submittal deadlines for each specific category, as most items are due for judging the week prior to the fair opening.
So, let nostalgia win you over as you prepare your home-grown vegetables and flowers for submittal to the North Florida Fair. You might just earn a blue ribbon to be displayed for all fair attendees to admire, either as they walk off a full stomach in preparation for more rides, on their way to the exits, or just as they get started creating their own fond fair memories.

Food is wasted along the many routes in our food system as it is grown, processed, transported, sold, stored, and prepared. According to the Environmental Protection Agency, the U.S. generates more than 37 million tons of food waste annually, 95 percent of which ends up in landfills or incinerators. That amounts to over 200 pounds of wasted food per every American every year!
Food waste in landfills combines with anaerobic conditions (lack of air) to create methane, a powerful greenhouse gas 25 times more harmful than carbon dioxide. Landfills are responsible for 18 percent of total methane emissions in the U.S., which contributes significantly to climate change.

Nationally, we can prevent and recover food waste by implementing techniques such as standardized food labeling, streamlined donations to foodbanks, the creation of secondary grocers, industrial composting, clean energy creation through treatment plant digestion, business and consumer education, and changing overall food policy.
But as a gardener, what can you do to help? If you grow fruits and vegetables, you are already helping, as this means the food from your garden did not have to travel long distances to get on your dinner table. If you actively compost your kitchen scraps, you are also helping, as Americans throw out nearly 40 percent of food purchased. Here are a few other simple life-style changes you might want to try:
Purchase more locally produced food. Buying local not only supports local farmers, but the food most likely used fewer resources than non-local food on its way to market.
Learn canning and pickling techniques. Homegrown fruits and vegetables are as fresh as you can get, and canning can then preserve this food for months.
Store food properly and keep perishables and leftovers in plain sight in the refrigerator so you see them every time you open the door. Investing in a good set of clear glass reusable containers can securely store leftovers, make them easier to identify, and can be safely heated for quick consumption.
Don’t throw out something just because it is past the date on the label. Unless it is baby food or formula – which federal law mandates be dated to ensure consumption when most nutritious – these dates refer only to peak quality. If the items do not show signs of spoilage, such as an off odor, texture, flavor, they are safe to consume.
This late winter has been alternating between warm and cool extremes. One thing is for certain and that’s that it’s time to start planning your sweet potato crop.
Sweet potatoes are generally planted March through June in the Florida Panhandle. The most common method of planting is with sweet potato slips. Sweet potato slips are simply six to eight inch cuttings of a sweet potato vine with the majority of the leaves pulled off. You can purchase sweet potato slips from a local garden center or a seed catalog. Make sure you only purchase certified, disease free slips. You can also easily start your own sweet potato slips from a store-bought sweet potato.
Sweet Potato Slip Production
Pre-sprout Your Tubers – Place sweet potato tubers in a warm place (75 to 85 degrees) with high humidity (90%), such as in your garage, for two to four weeks. It is important that you put the tubers in a well-ventilated container. Allow the tubers to stay in the pre-sprout area until sprouts are roughly 1/4-inch in length.
Bedding – Sweet potatoes are placed in “beds” to produce slips. A sweet potato bed can be made out of the same materials as you’d use for a raised bed garden. You can simply build a frame out of 2″x12″ lumber. Plastic is placed in the bottom of the beds before a layer of bedding material is put down. The bedding media can be a peat-based potting mix or a more economical substrate would be wood chips or sawdust. Sprouted sweet potatoes should then be placed in a single layer 8″ to 12″ inches apart and covered with two additional inches of bedding material. Then top dress the bed with a general purpose, granular fertilizer, water the bed, and cover with clear or black plastic. Poke holes in the cover plastic to aerate the soil and prevent carbon dioxide and temperature buildup. You may need to water the bed periodically, but do not completely saturate. Sweet potato slips can also be produced in the garden if you have a sandy, well-drained soil such as the field pictured below.

Cut Slips – Slips will be ready to cut in seven to ten weeks. Cut slips 1″ above the bed surface and trim to 10″ to 12″ in length. Strip all but the top one or two leaves from each slip. If you are unable to plant your slips at the time of cutting, then store them in a cool, dry area to prevent them from rotting.
Sweet potato slips can be planted March through June in the Florida Panhandle. Plant the slips at least three nodes (leaf stubs) deep at 12″ by 36″ spacing. Fertilize based on soil test recommendations. Sweet potatoes are ready to harvest generally between 100 to 120 days after planting slips. After harvest, you will need store your sweet potatoes in a warm (80 to 85 degrees), humid (80 to 90%) place for one to two weeks to allow them to “cure”. After the curing period, you can store your sweet potatoes in a cool area (55 to 60 degrees) until you are ready to eat them.
