Are you tired of seeing only green from your shrubs such as boxwood or yew? Are the areas next to your home walls, fences, terraces, tree islands, gate entrances, and/or borders barren? Do you want to add color to these areas? You may want to consider planting these areas with the beautiful amaryllis (Hippeastrum x hybridum).
Amaryllis grows from a tough, dependable bulb that will bloom during the spring after winter dormancy. The strap-shaped leaves will emerge first and grow about 1.5 inches wide, up to three feet long, and persist much of the year in Florida. They are reduced later in the summer and ultimately die back from frost.
In the late winter, bulbs will eventually produce one to three leafless stalks, or scapes, that will each have two or more trumpet-shaped flowers. Flowers come in a variety of forms and shapes: from single and double, miniature or large. Flower colors can be red, bright pink, shades of pink, orange, white, rose, or even salmon. It does not stop there! The flowers may even be striped and multi-colored. Amaryllis can create a striking focal point when they are planted in clusters of 10 or more of similar color.

Amaryllis may be planted anytime of the year, but winter is best. They are sun- and shade-tolerant, but planting in light shade is best since leaves will yellow in full sun and plants bloom poorly in heavy shade. Amaryllis prefer well-drained sites to prevent bulb and root rots.
For the best amaryllis performance, till and amend the soil with a 3- to 4-inch layer of organic matter and 2 to 3 pounds of 6-6-6, or a comparable amount of other complete fertilizer per 100 square feet. Plant 12 to 15 inches apart. Amaryllis can greatly benefit from at least one fertilizer application in the early spring and two to three applications during the growing season.

After flowering it’s a good practice to remove the stalks, unless seeds for planting are desired. If the bulbs become crowded, dig and separate them out. Doing this will encourage large, uniform flowers.
Go out, plant a few amaryllis plants today, and be ready to. To learn more about Amaryllis, please follow this link.

Carrots growing in a large container.
After tending a home vegetable garden for any length of time in the Panhandle, you begin to learn some things. Tomatoes are awfully hard to grow. Raised beds drastically lower the difficulty of gardening in general. You should never plant mint in a permanent veggie garden. Swiss Chard has to be started early because it grows as molasses creeps. Of all of these anecdotal maxims I’ve discovered, the one with the most flavor return on my gardening investment is that carrots should always be a part of your cool season garden. A fresh carrot out of the garden is hard to beat. The difference between a grocery store carrot and one fresh out of your own garden is astonishing and will change your culinary life. Though carrot season in Florida is just ending (my final batch was harvested yesterday), it’s the perfect time to learn about growing carrots here and plan to get some in the ground this fall!
There are a number of reasons to grow and eat carrots. They’re obviously very healthy, though I dispute the whole eat carrots and you’ll have great eyesight thing – apparently I acquired the taste for them too late to help. They go well in more dishes than they don’t. However, the real two reasons you should supplement your grocery store carrot purchases with home grown harvests are that they’re so easy to grow and that there are so many more options than the standard long, thin orange varieties adorning the produce aisle shelves.
‘Bolero’ Carrots
Though carrots are remarkable easy to grow, they do ask a couple of things of gardeners. They are a cool season vegetable and are generally planted from seed beginning in late August through early September in the Panhandle, though successive plantings can continue through at least February if you want to extend your harvest. Also, like many other root vegetables, carrots don’t transplant well so direct seeding in the garden is a must. But before you even consider seeding, care must be taken to make sure the soil bed you’ll be seeding in has been properly prepared. One of the few ways to fail growing carrots is to not start with a loose soil free from any potential obstructions. If the development of the carrot root is disturbed by anything during the germination and growing process (this includes manure aggregates or other clumpy soil, sticks, rocks or even a hard layer of soil hiding under your loose compost), the end product will be deformed. To prevent this, thoroughly till your raised bed soil to at least 12” and break up any larger soil particles that are left with your hands. If you don’t get your soil bed perfect though, fear not, deformed carrots are definitely edible, they just won’t look like they’re supposed to and are more difficult to clean and process!
Deformed carrots due to clumpy compost!
Once you’re ready to plant, I’ve found it easier on poor eyes and fumbling fingers like mine to sprinkle the tiny carrot seeds in shallowly furrowed rows 10”-12” apart and thin the seedlings later, rather than trying to individually space seeds the recommended 1”-3” apart. Finally, these colorful little veggies love water and require good fertility. To ensure good expansion of the edible root, maintain consistent moisture and fertilize at planting with a good slow release fertilizer. Additional fertilizer applications may be required later in the growing season as most carrots take around ten weeks to gain maturity.
‘Sugarsnax’ (orange) and ‘Malbec’ (red) carrots
In this age of online catalogs, farmer’s markets, and demanding consumers who crave interesting food, the selection of carrot varieties available for gardeners to grow has never been better. Among the hundreds of individual cultivar options are several broad types of carrots you’ll need to choose from. You’re probably familiar with the Imperator types. These are the extra-long, durable carrots most often find in stores. If you have a deep raised bed or other large container, Imperator varieties can be extremely rewarding! I grew the Imperator-type ‘Sugarsnax’ this year and highly recommend it for ease of growing, size and flavor. Next up are the Nantes types. These carrots are medium length and cylindrically shaped. Sometimes called “storage” carrots, these types tend to store well for long periods of time after harvest and retain their flavor well. I’ve tried a few over the last several years and can recommend ‘Bolero’ and ‘Napoli’ with confidence. There is even a carrot type for those of you with shallow raised beds (8” or less) that can’t accommodate the previously listed types! Chantenay type carrots are excellent performers in these situations as they are generally a bit shorter and possess a conical shape with roots wider at the top and tapering to the tip, making a deep soil bed a bit less critical. Finally, there are even some excellent cultivars of carrots in colors other than orange! That’s right, you can grow white, purple, yellow, and even red carrots! I’ve done very well with ‘Purple Haze’ (purple with orange interior), ‘White Satin’ (creamy white color), and ‘Malbec’ (deep, rich red) and highly recommend all three. Keep in mind that the red and purple carrots tend to lose their color when cooked, so the greatest effect is seen when eaten fresh. All of these cultivars can be found at nearly any of the numerous online and catalog seed retainers such as Johnny’s Selected Seeds, Baker Creek Heirloom Seeds, Burpee, and others.
As you can see, carrots are an easy to grow, extremely rewarding vegetable for the home gardener; give some a try in your raised beds next fall! And as always, if you have any questions about growing carrots or any other gardening related question, contact your local UF/IFAS Extension office!

Winter is in full swing and home grown produce is probably not the first thing that comes to mind. But it should be! It’s time again to start thinking about spring vegetable gardening. While a number of crops can be started by direct seeding in the soil, success rates are higher when plants are started indoors or in a covered structure. In order to be successful, it’s important that you follow some simple steps.

- Transplant Trays/Flats – Trays are made from different materials such as plastic, polystyrene, and compostable materials. Different cell sizes are also available. Generally, smaller cells are used for smaller seeds and larger cells are used for larger seeds. It’s important to think of the life cycle of the crop. For example, lettuce and other leafy greens have much shorter life cycles compared to tomatoes. Because of this, they have smaller root systems at transplant time and may not develop a good rootball in a large cell. Therefore, lettuce would perform better in a smaller cell.
- Media – It’s important that you choose a germination mix instead of a potting mix. Definitely don’t use garden soil! Germination mixes are typically a combination of finely ground peat, perlite, and other soiless substrates.
- Seed – Purchase seed from a reputable source with a germination guarantee. If you save seeds for future gardening, then store them in a cool, dry place. Seed can be stored in the refrigerator. However, do expect the germination rate of stored seeds to diminish over time. Coated seed is recommended for smaller seeds to make seeding easier and more efficient. Seeds should be planted in media at a depth of approximately 3 times the diameter of the seed. Check the seed package for additional planting recommendations. For more germination and storage information please see this publication from the University of Nebraska.
- Fertilizer – Too much fertilizer can result in leggy and possibly burned plants. A 20-10-10 (or similar ratio N-P-K) water-soluble product is generally used in commercial production. Rates are dependent on crop, sunlight, and temperature. The media should be kept moist, but not continually wet.

Seeds can take up to 14 days to germinate depending on species and conditions. Most transplants are ready for the garden by 6 to 8 weeks. To improve success rate and accelerate production time, most farmers harden off their transplants before planting. Hardening off is the process of stressing the transplants for about a week. Generally, transplant trays are taken out of the greenhouse (or other transplant area such as a window sill) and set outside. Watering frequency is reduced and fertilization is halted. It’s important that the plants aren’t completely neglected, but just stressed enough to prepare them for the elements. A good place to put the trays is under a tree in partial shade. After this hardening off period, the transplants are ready for your garden. Hopefully these tips will make you a more successful gardener!

Many Americans have a remarkably unrefined taste in salads; my brother has long counted himself in this group. Dice up some crunchy Iceberg type lettuce, splash on a dollop of ranch dressing, maybe chop a leaf of romaine up if you’re feeling frisky and call it a salad, this is the way we’ve been trained to eat. I’m here, a voice in the supermarket produce aisle wilderness calling, to tell you it’s time to open up your palate, look beyond lettuce, live a little, and add some spice to your life and salad bowl with three of my favorite easy to grow leafy greens: Mizuna, Frilly Mustard, and Italian Dandelion.

Before we get into species specifics, let’s cover a couple of reasons you should grow them at home! Growing your own flavor-packed greens has many benefits. First, leaves from these plants can be difficult to find anywhere but specialty health food stores or high-end supermarkets. Growing your own ensures a consistent supply, especially if one utilizes the “cut and come again” harvesting method (just remove the leaves and stems you need that day, leave the crown intact and allow the plant to regrow for next week’s harvest). Second, you do not have to worry about the too common food safety recalls and other health scares involving “leafies”. If you follow standard safety practices (clean irrigation water, wash picked leaves and store properly, etc.), you’ll be eating scrumptious salads when everyone else is begrudgingly trashing entire bags of recalled store-bought greens. Finally, each of these species double as gorgeous accent plants in

raised beds or containers. I love plants that do heavy lifting as both eye-catching ornamentals and delicious edibles!
Mizuna is a little known member of the mustard family that is quickly becoming one of my favorite leafy greens! It faces no major pest or disease problems in the garden and it is extremely tolerant of the cold weather Floridians periodically face through the winter, laughing off frost. Mizuna possesses lovely, deeply cut, pale green, fringy leaves complete with crispy white stems, all of which are edible – no need to separate stems when processing to eat! This lovely little Asian green has a mild peppery taste (think a toned-down Arugula) and adds perfect flavor and texture to any salad!
Many Southerners are well acquainted with traditional Mustard greens and their preparation (more than a little bacon and salt) but may not be aware of newer Mustard cultivars that give the species a bit of refinement and make it a salad celebrity! This winter, I’m growing a cultivar of Mustard called ‘Scarlet Frills’ (aptly named with finely serrated burgundy-red leaves) and really enjoy its peppery horseradish taste as a foil to the mildly sweet taste of traditional salad greens like lettuce and spinach. Mustards are extremely cold tolerant and slow to bolt, making it a mainstay in the salad garden all winter long; you really get your money’s worth from a few Mustard plants! However, even if this leafy green wasn’t delicious, it would be worth growing. The “fancier” Mustard cultivars are highly ornamental and deserve a spot in any cool season container garden.

Finally, the one that turns up the most noses when I mention growing and eating it, Italian Dandelion (Cichorium intybus)! I’m not advocating foraging in your turfgrass to find dinner, in fact, Italian Dandelion is not a true dandelion (it’s actually a chicory). However, it does share a number of features with its weedy cousin, including leaves that are similar in appearance and a vigorous taproot. That’s where the comparisons stop though, as Italian dandelion is a superior garden plant, more upright growing, much larger, and deeper green (some varieties including the one I grow ‘Italiko Red’ have red veined leaves) than its wild cousin. Unlike Mizuna and some of the milder mustards, Italian Dandelion is a bit of an acquired taste. It imparts a strong bitter flavor that may be cut with milder greens in a salad or cooked down to reduce bitterness. Either way you try it, put Italian Dandelion on your cool season garden next year!
Mizuna, Frilly Mustard, and Italian Dandelion all require similar growing conditions. In Florida, leafy greens are cool season vegetables, growing through the fall, winter and spring months. Seeds should be sown in late September and can be stagger-sown (plantings every couple of weeks) to ensure a steady supply through spring. As a rule, they prefer rich, well-drained soil high in organic matter. These soil conditions are achievable with either quality commercial potting mixes or homemade concoctions of compost and pine bark. The beds or containers you fill with the aforementioned soil should be sited near a good water source (plants that aren’t convenient to water get neglected, trust me) in an area that gets 6-8 hours of full sunlight. I like to topdress at planting (if using transplants) or after germination (if using seed) with a good general purpose, slow-release fertilizer, many formulations and brands that work are widely available for purchase. Finally, be sure to purchase seed from a quality source. Online purveyors Johnny’s Selected Seeds, Baker Creek Heirloom Seeds, and Sow True Seeds are good places to start, though the options are nearly endless!
Next year, when planning your cool season garden, remember to add a little spice with these three leafy greens, Mizuna, Frilly Mustard, and Italian Dandelion! For more information about cool season gardening and other topics, consult your local UF/IFAS Extension Office.

Fatsia japonica, common name Japanese aralia, provides tropical texture to your landscape. That coarse texture is attributed to its large (nearly a foot wide) leaves that are deeply lobed (maple leaf shaped). This shade-loving plant performs well in moist (not soggy) locations. Upright stems originate near ground level usually near the base of older stems. The stems grow to about eight feet tall before bending toward the ground under their own weight.
Even though the foliage of this species is enough to make you want it in your own garden, you will absolutely fall in love with its blooms. Upright clusters of showy, creamy white flowers begin to appear in fall. These little snowballs provide wonderful color to your garden. The shiny, black fruits appear in winter and are prominent for several weeks. The fruit are know to attract birds to the landscape.

Fatsia japonica thrives in the shade in slightly acidic, nutrient-rich, moist soil. Older stems become leggy and can be cut back to encourage branching. In the right place, Fatsia japonica is low-maintenance and not typically bothered by pests. It is also known to perform well in coastal landscapes. It fits well in entryways, in containers, or in mass plantings spaced three feet apart.
