With the holidays in the rear-view mirror, the list of tasks has returned to the norm. While recovering from the parties and gift giving expenses, the home landscape now appears on the long list of New Year’s resolutions for most homeowners.
The shorter daylight hours and the cooler thermometer readings have slowed, but not stopped the rate of growth and development for most ornamental horticulture used in the panhandle. Still, some chores completed now will deliver big payoffs when the growing season returns.
The first and most efficient action is to have a soil test done. Any number of actions and environmental factors can increase the likelihood of change to the soil’s nutritional profile.
This test report will determine the available nutrients and identify any deficiencies in the home landscape. Given the amount of time and resources invested in home landscapes, the soil test is an excellent investment to achieve success.
No matter if using a shovel or a soil test probe, the information on a soil test is critical to achieving maximum performance from turfgrass while assuring the responsible application of fertilizer.
The process is simple, easy and inexpensive. Sampling kits are available at UF/IFAS local County Extension Offices, and tips on effective sampling techniques are available upon request from the horticulture staff and Master Gardener volunteers.
There are also commercial soil testing labs which can be located on the internet. They offer a variety of testing services beyond soil testing.
Kits for testing at home are not recommended. Their accuracy is dubious and can be swayed by a variety of factors which render the results useless.
There are several characteristics common to panhandle Florida soils, but they are not universal. Testing will assure the homeowner can apply amendments in the correct amounts.
PH, the measure of acidity or alkalinity, is a critical component of the soil test report. Many soils in coastal counties are in the alkaline range which affects the nutrient absorbing ability of commonly used turfgrasses, shrubs and vegetable plants.
There are ways to mitigate or overcome soil pH problems with the correct application of micro-nutrients or, in the cases of growing beds, mulches. These are all well within the abilities of homeowners to accomplish with readily available inputs.
Another common trait of Florida soils is naturally occurring high amounts of phosphorus. This element is mined in the central region of the state and shipped nationwide in commercial blend fertilizers.
The middle number on a fertilizer analysis tag reflects the percentage of phosphorus available in the bagged product. For example, a 50-pound bag of 5-10-15 would have five pounds of phosphorus.
If, as is commonly the case, the soil test report indicates phosphorus is present, application is not needed. Excesses of this nutrient tend to leach into the aquifer and surface water bodies, potentially causing an assortment of long-term problems for everyone.
This information contributes to economically and environmentally sound decisions which will be carried out in spring. It will also help if selecting a grass species which can be planted or over-seeded in patchy spots in late winter.
As with bagged fertilizers, there are many choices to consider. Read the seed tag carefully if considering a blended product.
Some generic mixed products will include grass seed which will not flourish in north Florida. Examples of grasses which do not grow well locally include fescue, bluegrass, and orchard grass.
So, when taking a break from football playoffs and paying bills, escape to the yard and pull a soil sample for testing. It will be the best thing next to a Super Bowl party with great friends.
