Interested in growing vegetable crops but have limited space for a garden bed? Maybe you live in an apartment, have poor soil, or you can’t find a sunny enough location to start an in-ground garden.
The good news is you can grow nearly any crop in a container! Even crops such as beans, squash, watermelon, and sweet potatoes can be grown to maturity and produce high yields if they are grown in properly sized containers with nutritious potting soil.
The Container Gardening: Recommended Varieties and Spacing chart covers the recommended minimum container volume, container depth, plant spacing, and varieties that do well in containers for each crop:

North Florida weather brings its ups and downs, and there are times during the winter season when the downs are low enough to trouble even cold-tolerant crops. Gardeners who wish to keep their plants growing as long as possible, or give them a head start in the spring, may want to consider installing low tunnels.
The term ‘low tunnel’ refers to a structure used for season extension that is usually made of hoops covered with some material, such as fabric or plastic. A low tunnel, as you might surmise, is low to the ground, like a miniature greenhouse that just covers the plants. They are usually no more than a few feet in height. A high tunnel, by comparison, is tall enough to walk in, but with a similar sort of construction.
These are versatile structures, which can act as more than just protection from cold. Low tunnels can be easily modified to provide extra shade for crops during the hottest months. A lighter fabric or fine mesh can also be used as protection from insect pests. Low tunnels can be constructed to stand on their own or may be integrated into a raised bed. They may even be placed inside a larger structure such as a high tunnel to offer a double layer of protection.

The cover of a low tunnel can be plastic, fabric, shade cloth, or even insect netting, depending on the needs of the crop. The hoops that hold the cover may be made of any sturdy material, such as wire, pieces of PVC, or metal electrical conduit. Hoop benders are available to help bend metal conduit to the correct shape. For more information about low tunnels, please see this EDIS publication.

Cruciferous vegetables, mostly cool-season annuals in the Brassicaceae (formerly Cruciferae) family, are part of a healthy diet, prized for their high fiber content and unique sulfur-containing compounds known as glucosinolates. This vegetable family includes things many of us love (or love to hate) like Brussels sprouts, cabbage, cauliflower, collards, kale, mustard, turnips, bok choy, and Chinese cabbage. They’re also commonly grown in Panhandle gardens. However, as anyone who has grown these species knows, some are easier than others. For example, kale and radish are among the easiest of all plants to grow. But get beyond the basics and folks often run into difficulty with species like broccoli and cabbage. The high rainfall/humidity and frequent warm spells experienced here during the growing season often lead to serious pathogen problems, dooming my garden in years past. However, this winter, thanks to a couple of new cultivars, ‘Capture’ Cabbage and ‘Burgundy’ Sprouting Broccoli, I’ve enjoyed a plentiful supply of tasty crucifers!

4’x 8′ raised bed planted with ‘Capture’ on 24″ centers.
‘Capture’ Cabbage, developed by Bejo Seeds of California as a mid-season “white” fresh market cabbage for the South, has been an outstanding performer in my garden this year. Touted as highly resistant to Black Rot and Fusarium Yellows (by far the two most devastating pathogens of Cabbage), I had to try it for myself. I planted seeds 24” apart in my standard 4’ wide x 8’ long x 12” deep raised beds filled with mushroom compost and aged pine bark. Seedlings were fertilized once about three weeks after germination with a general purpose 10-10-10 fertilizer. The plants that developed have been extremely vigorous (I’m glad I paid attention to plant spacing guidelines on the seed packet!) and have not shown ANY evidence of disease, even through an unusually warm and wet winter that would have hammered older susceptible varieties. My plants have begun to develop heads and should be ready for harvest and the kitchen in just a couple more weeks! If you’ve had problems getting a cabbage from germination to head formation and harvest without serious disease pressure, give ‘Capture’ a try next fall!

‘Burgundy’ Broccoli in the author’s raised bed garden.
‘Burgundy’ Broccoli, developed by Elsom Seeds in the United Kingdom, is a unique variety sure to turn heads in your garden. True to its name, the prolific florets are a deep, purple color. Though the central “head” on ‘Burgundy’ is quite small, that’s not the primary feature anyway. Considered a “sprouting” broccoli, this cultivar puts out an abundance of side shoots that make ‘Burgundy’ sort of a cut-and-come-again broccoli, allowing for a long harvest window. Another advantage from a disease avoidance perspective is the short maturity time (the time from planting seeds to having harvestable shoots) of around 40 days! For perspective, a “regular” heading broccoli has a maturity of around 60 day, lots more time for problems to happen. In the same growing conditions described above for cabbage, ‘Burgundy’ performed amazingly well for me, growing strong, healthy stalks, large, unblemished leaves and an abundance of purple shoots with a nice flavor profile!
If you want to enjoy homegrown broccoli and cabbage but disease pressures have made your previous efforts unproductive, give ‘Capture’ Cabbage and ‘Burgundy’ Broccoli a try! These two selections have made it easier than ever to enjoy unique, homegrown, healthy cruciferous veggies. Keep these and other quality, disease-resistant cultivars in mind when planning your winter garden in 2020!

There are hands-on agricultural crop displays and much more in the UF/IFAS building at the North Florida Fair. Photo by Molly Jameson.
New Demonstrations in the UF/IFAS Extension Building at the North Florida Fair
Every year during the North Florida Fair in Tallahassee, extension agents from all over the Florida Panhandle showcase their various programming in the UF/IFAS exhibitor building. This includes educational displays and hands-on activities in areas such as horticulture, agriculture, livestock, 4-H youth, natural resources, and family and consumer sciences.

Once you have your fill of fair rides and funnel cake, see a live educational demonstration at the UF/IFAS building! Photo by Molly Jameson.
For instance, visitors can view and touch agricultural crops grown in our area, play in a giant tub of actual cotton, match images of song birds with their names, make a 4-H craft, and learn about the importance of wildlife habitat for animals.
This year, Extension is including even more to do and learn in the UF/IFAS building. There will be live demonstrations taking place throughout the fair week, which is November 7 to 17 this year.
Did you know you can convert recycled containers, such as milk jugs and soda bottles into self-watering planters? Or that when saltwater reef fishing, if fish are brought to the surface too quickly, it can rupture their organs? Learn all about these concepts and more during the UF/IFAS Extension Live Demonstrations.
UF/IFAS Live Demonstration Schedule:

Gardening is an attractive pastime, not only for homeowners but also, it seems, for every critter out there that wants a free meal. If a gardener isn’t trying to keep deer, rabbits, or moles out of their crops, they’re fighting against insects of many

different sorts. With as many different sorts as there are, it can be dizzying to try and keep track of them and to figure out what’s doing damage to which vegetables.
Just because you see an insect in your garden doesn’t mean it’s a bad one. There are many that can be friends to a gardener, patrolling the plants to snack on pests. It’s important to know what you’re looking at before you try to control them; you might end up killing off a helpful bug instead of one that’s a problem!
It can be helpful to look at the damage done by the insects that are plaguing your garden to figure out what kind they are. Piercing / sucking insects drink the fluids from inside plant tissues, and leave small dots or stippling marks, and may exude honeydew, a stick fluid that sometimes grows sooty mold on

it. These bugs include aphids, scales, mealybugs, spider mites, stink bugs, and thrips.
Chewing insects are those that usually go after plant leaves. They chew holes, and if an infestation is bad, they might defoliate a plant very quickly! Caterpillars, grasshoppers, and some beetles are the worst offenders of this sort.
If you need help identifying or figuring out how to control an insect in your garden or any other horticultural topic, feel free to contact your local UF/IFAS Extension office!
