It is freezing cold this week and hard to believe that we are already talking about “What to Plant” and “What to Do” to get started early. In North Florida there are cool-season annuals that can be planted now. The list includes pansies, violas, petunias, and snapdragons. As we are coming to the end of January it is time to plant crinum, agapanthus and gloriosa lily bulbs.  Make sure to mulch these areas after planting to protect them from the cold temperatures. This is also the month to plant camellias, which these come in many colors and forms that your local nurseries will carry this time of year. If you haven’t planted all your cool season crops there is still time to do that now such as broccoli, kale, carrots, and lettuce. Irish potatoes can be planted now as well.

Now you might be asking “What can I do?”. January is a great time to prune non-spring flowering shrubs and trees to improve their form. This is a good time to plant deciduous fruit trees, this will give their roots time to develop before the warmer spring temperatures. Since existing trees are dormant, it is a good time to prune and fertilize them. When the temperatures are near freezing many of the tender plants will need to be covered to minimize damage.  It’s a good time to plant a tree.  Hurricane-resistant trees include live oaks, bald cypress, cabbage palms, and southern magnolias.  It’s time to remove those dead spent seed pods on your crape myrtles and removing any crossing branches and twiggy growth will improve the appearance and the form of the plant.

As we go into February it will soon be time to apply a preemergence weed killer to your lawns to prevent warm-season weeds. Temperatures must rise to 65°F for 4 to 5 consecutive days before you do a preemergence application and make sure you are not using a weed and feed fertilizer.  Citrus and other fruit trees can be fertilized at this time. The amount and frequency will depend on the age and type of fruit tree you are growing.  Avoid pruning Citrus until spring to avoid any injury since cold temperatures are still possible.  It is time to prune those roses this month to remove damaged canes and improve the overall form.  After the pruning is complete you can fertilize and apply a fresh layer of mulch.  They should begin blooming within 8 to 9 weeks after being pruned.

Dianthus, pansies, violas, and dusty millers are annuals that can take a chill and should be planted in February.  You can continue to plant crinum and agapanthus this month and add on amaryllis and rain lily bulbs as well.  If it has been dry make sure to provide plenty of water for the bulbs to establish and continue to protect them from the cold by adding mulch. Trees and shrubs will begin to bloom this month including red maples and star magnolias. Continue planting potatoes throughout the month and towards the end of February warm-season crops like tomatoes and pepper can be planted but be prepared to protect them from any late frosts.

What Does a Vegetable Garden Cost?

It’s never too early to start thinking about your spring vegetable garden.  Have you ever wondered how much it costs to grow your own vegetables?  Does it cost less to grow your own vegetables or buy them from the grocery store or farmers market?  A number of factors are involved with answering these questions and budgeting for your home garden.

Materials

The materials used are specific to your own vegetable garden.  If you do everything by hand you may need a hoe, rake, and spade along with a number of other tools you can use from year to year.  When budgeting for you garden you would need to think about the life expectancy of these tools.  Let’s say a $20 rake lasts for 10 years.  In that case, you would budget $2/year ($20 ÷ 10 years = $2/year) for the rake.  This might also be the case with a bag of fertilizer.  You may buy a 50 pound bag of fertilizer and use half the bag in year one and the other half in year two, so the cost of the fertilizer would be cut in half for your yearly budget.  Other materials may be purchased for just one growing season such as pine straw for weed suppression or you may buy only enough seeds for the season.

Labor

A lot of work goes into growing your own vegetables.  If you have the time and enjoy gardening then you may choose to charge yourself nothing for your work.  However, from a cost analysis perspective you may want to put a value on your work.  This will give you a better comparison to buying vegetables.

Budgets

Of course you could create your own budget based on all the costs that go into gardening.  But why do that, when it’s already been done for you.  The UF/IFAS Costs and Benefits of Vegetable Gardening publication includes a Microsoft Excel Cost Workbook to help answer some of these cost questions.  This budget template is customizable, so it’s important that you consider all the costs for your vegetable garden.  If you are looking for more detailed crop budgets, there are a lot of North Florida Enterprise Budgets available from UF/IFAS.

Should Pepper Seeds Be Saved?

Should Pepper Seeds Be Saved?

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.

  1. Isolate plants from pollinizer insects by growing them indoors or in a greenhouse.
  2. Cover individual plants with insect exclusion netting.
  3. Separate different varieties by at least 400 feet.
  4. 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.

Tomato Pruning Tips

Tomato Pruning Tips

With the traditional planting date of Good Friday behind us, the home tomato gardening season in the Panhandle is in full swing.  While tomatoes are the most persnickety veggie we grow, there are several practices you can adopt to help you succeed: selecting an adapted variety; regularly scouting for insects and disease; and watering and fertilizing appropriately.  However, the most overlooked practice for success gardeners can adopt is proper pruning.

Correct pruning does a couple of positive things for tomatoes.  First, it reduces the incidence of disease by preventing leaf contact with the soil, opening the interior of the plant, and allowing better airflow.  This is important as many plant pathogens reside in the soil and only need a splash of water to travel onto plant leaves.  Also, densely foliaged plants trap warm, moist air in their canopies, creating a perfect environment for disease to flourish.  Letting the plant canopy “breathe” through pruning prevents that negative environment from forming!  Second, correct pruning of “suckers” (extra growth points that can develop into shoots) helps tomato plants develop optimum yield and fruit quality.  By removing suckers, more water, nutrients, airflow, and light are directed to the main stems, where the majority of tomato fruit production occurs.  Failing to remove suckers (especially on indeterminate varieties) can result in reduced yields, increased disease, and generally messy plants!

With the reasons for pruning tomatoes established, the next step is learning exactly what to prune and how to do it in a sanitary matter.

  • Get rid of any foliage that could encounter the soil, generally all leaves occurring on the lower 12-16″ of the plant.  All kinds of nasty tomato destroying diseases, like Early Blight and Bacterial Leaf Spot, reside in the soil and are just waiting to be splashed onto your plants – don’t let that happen.
  • Determine how many primary shoots you want your plant to have.  Leave enough lower suckers to achieve that number (generally just one, two, or three as more than 3 primary stems gets hard to manage), and prune or pinch out all the rest.  To prevent stress from pruning, be diligent in removing suckers when they are still small, 2” or less.
  • Always clean and disinfect your pruners before making a cut on a tomato plant.  This is best accomplished by rinsing the blades with warm soapy water, drying, and following with by a quick alcohol spray.  A 10% bleach solution will also work, but if not thoroughly rinsed after, bleach can corrode pruner blades and other working parts.  If you make cuts on a plant that appears diseased, repeat the sanitizing process before you begin pruning another plant as “dirty” pruners are an easy way to spread pathogens in the garden.

While tomatoes are indeed a difficult vegetable to grow, learning to prune them correctly will greatly help to make this a successful season.  If you just keep leaves off the ground, suckers pinched, and pruners cleaned, you’ll be well on your way to less disease, prettier plants, and more tomatoes to pick.  For more information on growing tomatoes and any other horticultural topic, please contact your local UF/IFAS County Extension office.  Happy Gardening!

Colorful Carrots for the Home Garden

Colorful Carrots for the Home Garden

Carrots are synonymous with a few things: Bugs Bunny, old wives’ tales about improving eyesight, and the color orange.  For centuries, orange colored carrot varieties have been the industry standard and still dominate store shelves.  These days though, choices for consumers are ever expanding and thankfully home garden carrot variety selection has participated in this phenomenon!  With a little searching, gardeners can now source and plant any color and/or type of carrot they desire.  For instance, this winter, I planted carrots of various types in various shades of orange, purple, and red. Through this experience, I also found that not all colored carrots look, cook, or perform the same.  The following is a quick primer on carrot types followed by my review of the four varieties ‘Bolero’, ‘Red Sun’, ‘Deep Purple’, and ‘Malbec’ after a season of growing.

Carrot varieties (left to right): ‘Bolero’, ‘Red Sun’, ‘Deep Purple’, ‘Malbec’.

There are three main types of carrots regardless of color:  Imperator, Nantes, and Chantenay.  Imperator types are the extra-long, durable, sweet tasting carrots most often found in stores and are suited best to deep, loose soils.  Nantes type carrots are medium length and cylindrically shaped, often with a blunt tip.  Sometimes called “storage” carrots, Nantes types are easy to grow and tend to store well for long periods of time after harvest and retain their flavor well.  Finally, Chantenay type carrots are excellent performers in shallower beds or soils as they are a bit shorter, possessing a conical shape with roots wider at the top and tapering to the tip, making a deep soil bed a bit less critical.  I primarily grow Imperator and Nantes types as I find they give you a little more bang for the buck if you have a deeper (>6”) raised bed.  Now, on to the variety reviews.

‘Bolero’ – I always have this carrot in my garden.  An extremely versatile Nantes type carrot that has been a consistently high yielder for me whether I grow it in pots or in a traditional raised bed.  Typical for a Nantes type, ‘Bolero’ stores very well in the refrigerator and will change your culinary life if you’ve only ever eaten carrots purchased from a store.  They are excellent either fresh or cooked, with a complex, sweet taste.  If I could only grow one carrot, it would be this one.

‘Malbec’ – Colored carrots have a poor reputation as far as flavor is concerned.  ‘Malbec’ is the first non-orange carrot that changed my mind.  This Imperator type is as flavorful as they come, deep red throughout, and is easy to grow.  For some reason, ‘Malbec’ has been hard to come by the last two years, but if you spot seeds in a catalogue, online, or on a store shelf, it is well worth a purchase!

‘Red Sun’ – Winter 2020 was my first experience with ‘Red Sun’, a brand-new Nantes type carrot from Bejo Seeds.  I only planted this variety because I initially could not source ‘Malbec’.   Having said that, I was very pleased with ‘Red Sun’.  The carrots were extremely vigorous, had excellent top and root growth and mostly held their own with ‘Malbec’ flavor-wise in the kitchen also.  I would purchase ‘Red Sun’ again!

‘Deep Purple’ – Wow, they weren’t kidding when they named this variety!  Most purple carrots are colored on the exterior but fade to a “normal” orange at their core.  Not ‘Deep Purple’!  This Imperator type is strikingly dark purple, almost black.  Even the tops have a purple hue to them!  Cooking them was also an interesting experience.  Most colored veggies, peppers, carrots, and others lose their hue when cooked.  Not this variety.  Not only did ‘Deep Purple’ retain its color after cooking, my hands and cutting board turned a shade of indigo when preparing and, once put in a pan to sautee with other veggies, the juice from ‘Deep Purple’ dyed all the other veggies a deep violet!  While I wouldn’t grow ‘Deep Purple’ as my main crop carrot, it definitely has a place in the garden as a tasty novelty.

Carrots are among the easiest to grow, most rewarding vegetables in the winter garden.  Next fall, plant a variety of carrots in your home garden and enjoy the many types, colors and flavors that this tasty veggie has to offer!  For more information on the above mentioned varieties, home carrot gardening in general, or any other horticultural topic, contact your local UF/IFAS County Extension office.  Happy Gardening!
