Protect Tender Vegetables From Coming Freezing Temperatures

by Eddie Powell | Nov 17, 2014

Northwest Florida homeowners enjoy growing their own vegetables every fall, but are faced with cold weather issues, especially during the first few days of December. For example, most cole crops can be planted until November, but they must be protected from the cold weather or they will need to be replaced. A good variety of cold tolerant plants should be used in order to prevent total devastation of the garden by extremely cold weather.

Below are a few tips to assist the home gardener in growing a successful winter vegetable crop.

For tender plants, site selection should the top priority when preparing for a freeze. Vegetable plants need a site with good air drainage; not in a low area where cold air settles. Arranging tender plants along a barrier to protect them from cold winds improves the plants cold protection, especially from very hard freezes.
Poorly drained soils result in weak and shallow roots which are more susceptible to cold injury.
Plants grown with the correctly applied rate of nutrients will tolerate colder temperatures better and recover from cold injury faster than plants grown with little to no nutrients.
Watering vegetable garden plants before a freeze can help protect plants. A well watered soil will absorb more solar radiation than dry soil and will radiate heat during the night. This may increase cold tolerance by as much as 2°F.
Saturated soil conditions can damage the root systems of most plants over a few days, so make sure the ground is well-drained.
Healthy vegetable plants are more resistant to cold than vegetable plants weakened by disease, insect damage, or nematode damage. Routine inspection for pests and implementation of necessary control measures are essential.
Plastic or cloth coverings can help protect vegetable plants more from frost than from extreme cold. Covers that extend to the ground and are not in contact with the vegetable plants foliage will reduce cold injury. If the vegetable plant foliage is in contact with the cover it is often cold burned or injured because of heat transfer from the foliage to the colder cover. Some examples of excellent plant covers are cloth sheets, quilts or black plastic. If plastic covering is used, it is extremely important to remove the covering during the day to provide for ventilation of trapped heat.
Feel free to contact your local county extension office for information on cold protection, pest identification and recommended control measures.

Thinning Vegetable Seedlings

by Beth Bolles | Sep 30, 2014

Some vegetables and herbs like lettuce, carrots, collards, basil, and radish have very small seeds. It is difficult to plant these seeds so there is space between emerging plants for proper development. These plants will often need thinning after they mature. Thinning allows for adequate space for leaf and root development during the growing season. Crowded vegetables will compete with each other for water, nutrients, and sunlight and never produce quality plants. Here are the tips for thinning seedlings:

When plants are about 1 to 2 inches tall or have two sets of ‘true’ leaves’, it is time to thin out any crowded plants.
Look up the proper spacing between plants and thin out appropriately. Use the chart in the Florida Vegetable Gardening Guide to determine spacing for specific fruits and vegetables.
You may pull out seedlings with your hands or forceps to make space or use small scissors to cut off seedlings at the ground level.

It will initially look like you have lots of room in the garden but realize plants will quickly grow to utilize available space. Some young seedlings like those of radish or lettuce can added to dishes and eaten as sprouts.

Preparing Your Vegetable Garden

by Roy Carter | Sep 23, 2014

Healthful outdoor exercise, a feeling of accomplishment, and potential saving on the family food bill are good reasons why more and more Floridians are turning to home vegetable gardening.

Usually, the most physically challenging part of a vegetable gardening project is to get the soil ready for planting. However, whatever you do, don’t give in to the temptation to cut corners on this phase of the operation. If you do a poor job of preparing the soil, you can expect poor results from your garden, even if you work hard on planting and cultivation. If you’re planning a large garden, you may want to rent a rototiller or even a small tractor and plow, to use in preparing the soil. But, for a small backyard garden, you can do the work with a spade or shovel.

The time to begin soil preparation depends to some extent on what’s growing on your garden site now. If you have heavy weeds, or a cover crop, you intend to turn under; you should start a month to six weeks before planting. This also is the time to add lime, if needed.

If you’ve kept the garden site fallow, or you plan to remove all vegetation and no lime is required, you could prepare the soil and plant within two or three days. However, if you plan to work extra organic matter into the soil before planting, you should start two or three weeks ahead of time.

To prepare the soil, dig down six to eight inches, and turn each shovelful completely over. If you’re turning in weeds, or a cover crop, you should remove all the woody plant material as it won’t decompose very well.

After the soil is turned, break clods and level with a rake. Do this as soon as you can, to prevent excess drying of the soil, and to keep good soil texture. This is important, because a finely pulverized soil surface will make planting easier, give you better seed germination and help insure a more even stand of vegetables. It’s especially important to have fine textured soil when planting small-seeded crops, like carrots.

In some soil, it’s also necessary to add some kind of liming material well before planting at the same time you turn the soil. Lime reduces soil acidity. Without going into a chemistry lesion, lime adds calcium to the soil and makes minor elements move available to plants. The most commonly used form of lime is dolomite. Besides calcium, dolomite provides magnesium another important plant nutrient. [important]You should add lime only when a soil test indicates the need for it. Too much can be as bad as too little. [/important]

If a soil test indicates your soil is too sweet, or alkaline, you may need a special fertilizer program. The best thing to do before liming or adding sulfur to reduce soil pH is consult your local County Extension Office.

To summarize briefly, to have a good garden, you need to prepare the soil properly. Be sure to start far enough ahead of planting to allow organic matter to decompose fairly well. Turn the soil to a depth of six or eight inches. Make sure you have a level, finely textured surface before planting. If a soil test indicates lime is needed to give your garden plot the right acid level, it should be applied when your turn the soil.

Vegetable Crops for Fall Color

by Blake Thaxton | Aug 12, 2014

Color can make a landscape. Color highlights features of the landscape and draws the eye as a focal point itself. Spring color is dominated by lush new green growth, Summer brings on flowers of all kind, and fall brings the spectacular show of foliage.

[important]A new suggestion: use vegetable crops as fall color![/important]

Fall and winter vegetable crops for the panhandle of Florida bring a different hue of colors that can be utilized in the landscape. Let’s walk through a few that you may want to start seed for to brighten up your fall garden.

Swiss Chard

Swiss Chard brings several colors to our finger tips. Reds, Whites, Greens, and Yellows are all available from different varieties of these crops. Not only do they bring great color to the landscape but they also are sometimes referred to as the “Champagne” of greens. They can be directly seeded or transplanted and should be planted 6-12 inches apart.

Broccoli & Cauliflower

Broccoli brings a blue/green foliage and Cauliflower various colored heads. Both can bring great color to the landscape and allow for something delicious to eat in the very near future. Broccoli and Cauliflower transplants should be used for planting. Broccoli and cauliflower should be given plenty of room with approximately 24 inches between plants.
