<Also, the samples I took were not right near the roses where I have amended, so maybe that threw the test off?> So do another soil test.

You won't see any changes from lime additions until 6 months or so - so next growing season.

Who did those soil tests? The University of Georgia does soil testing and they will include a report with the test results about what needs to be done to correct any problems. Plus the people that work in the county offices are available to you to answer any questions you may have.

If you apply the proper amount of lime (that should be spelled out in the soil test) you need not be concerned about applying too much lime, but you cannot guess about that amount either. While it can take as much as 6 months for soil pH changes to be complete you will see changes during that time. If soil pH changes did not begin to take place sooner than 6 months you should not plant anything during that time and we all do, but this is one of the reasons why adjusting for soil pH is best done in the fall.

How much organic matter is in that soil?

How well does that soil drain? How well does that soil retain moisture?

What does the soil smell like?

What kind of life is in that soil?

How is the workability (tilth) of that soil?

odds are, you're fine. most plants prefer a pH slightly acidic, from 5.5 to about 6.5 specific plants may like different somewhat different readings, but there's not enough information to be able to provide any direction.

ask three people what to do with the results of a soil test, you'll have four answers. Did you do this just because, or do you have specific issues you'd like to address?

Low pH levels are the result of excess hydrogen. Adding carbonate will lower pH as the carbonate chemically reacts with hydrogen to create CO2 and water. There are only two sources of carbonate for soils: calcitic lime or dolomitic lime. Calcitic will add Ca, dolomitic will add calcium and magnesium (about 50% Ca to 40% Mg). It is what it is if you want to raise soil pH.

Most all plants have evolved over eons growing in soils with a pH near neutral, 6.0 to 7.0, where most all plant nutrients are most readily available. Some plant species evolved growing in soils with different soil pH levels. Getting the soil pH near what the plants grow best in is important so those plants can grow strong and healthy. There is ample information available about why plants should be grown in soils with the right pH to provide proper direction for the grower.
