 It’s
more fun to show off pretty flowers or share tasty vegetables. But
creating a healthy soil foundation will increase your growing
success which means more beautiful flowers, larger harvests, and a
healthier landscape to enjoy.
When creating a new lawn, landscape, or garden bed, begin with a
soil test. Use soil testing to evaluate your fertilization practices
and diagnose problems in existing lawns and gardens. Prioritize and
spread out the cost by starting with new and struggling gardens or
lawn areas. Then implement an ongoing testing schedule that tests
one or two existing gardens each year. Testing lawns and gardens
every few years can help improve their health while helping you
avoid improper and overfertilization that can negatively impact your
landscape and the environment.
A soil test report tells you what if any fertilizer
is needed and what fertilizer is best to use for the plants you are
growing. It also evaluates the soil pH, acidity, and alkalinity,
advising you of any needed adjustments. Testing this before
fertilizing or adjusting the soil pH can help avoid years of
problems caused by applying too much or the wrong fertilizer, lime,
sulfur, or other products.
You can take a soil sample for testing whenever the soil is not
frozen, and you have not recently applied fertilizer. Fall is an
excellent time as it allows you to implement the soil test results
before the next growing season.
Contact your local or state University Extension Service to locate a
qualified soil testing lab near you. Many have a state lab that
provides this service for a fee while others provide lists of
soil-testing labs in your area.

Take separate samples for each type of planting,
garden bed, and if needed, lawn area. As you may have discovered,
the soil can vary greatly from one place to another. Fill may have
been added when the house was built, topsoil used to create planting
beds, and other soil amendments incorporated that can impact your
growing success. Taking a sample from individual planting beds,
mixed borders, and the lawn provides better information on the
existing conditions and what is needed for growing those types of
plants.
Use a clean trowel and bucket to gather the soil sample. If needed,
slide away mulch and remove a narrow slice of soil, four to six
inches deep, where many plant roots grow.
Take several samples from the garden or lawn area you want to test.
Collect samples from each edge and several throughout the middle of
the bed or lawn area. Mix the samples together, place about a cup in
a plastic bag, and send it to the soil testing lab. Allow several
weeks for the test to be completed and the results returned.
Consider adding soil testing to your garden preparation and ongoing
care. This investment will help you grow healthier, more productive,
and more beautiful gardens and landscapes.
