Garden plot preparation

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.  Our information on garden plot preparation was provided by Emeritus vegetable specialist Jim Stephens, of The University of Florida’s Institute of Food and Agricultural Science.

Usually, the most physical part of a vegetable gardening project is getting the soil ready for planting.  But, 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 wood plant material, because 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.  You really should add lime only when a soil test indicates the need for it.  Too much can be as bad as too little.  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.
