Soil preparation is the most crucial step in success with annuals. Roots of annuals have to penetrate soils quickly, anchor plants, and absorb water and nutrients in one season, often under adverse conditions. Most Mississippi soils can be improved with cultivation and the addition of other ingredients.
Cultivating wet soils may cause lumping and shallow "pans," which resist air, water, and root penetration. Soil that is ready for cultivation holds its shape when squeezed, but crumbles easily. Power tillers are useful for preparing large areas, but may create a compacted zone in the soil directly under the tilled area. Use a digging fork to help avoid soil compaction.
The first step in preparing a bed for annual plants is to remove any unwanted plants with a hoe and rake or with a nonselective contact herbicide. After weeds have been removed or killed, dig the soil a shovel's depth; deeper soil preparation is normally not necessary. To prevent resprouting, remove grass and weed roots while turning the soil. Break clods and lumps into smaller pieces.
Add 3 to 4 inches of organic material, such as composted leaf and yard litter, pine bark, peat moss, or composted manure. Then add an inch or two of sharp sand if the soil is heavy. Also, if the soil test indicates a need for lime or fertilizer supplements, spread them at the recommended rate over the top at this time. Mix amendments together, blending the organic matter, sand, and fertilizers. Rake the prepared bed smooth when finished.

This weekend while driving in my hometown of Ocean Springs, I looked at the crape myrtles planted in the median all along Highway 90. I noticed that most of the trees had a dark cast to them, even on a bright, sunny morning.
About 10 years ago while attending a meeting in Miami, I had the opportunity to tour around south Florida, sightseeing and enjoying the horticulture.
You’ve spent all summer planting and maintaining your garden or mowing your lawn and are ready for a break. But before you put your landscape to bed for a long winter’s nap, consider applying lime.
