How Sod Installation Works
Installing sod correctly makes the difference between a lawn that thrives and one that struggles. The process involves more than just rolling out grass—proper soil preparation determines whether your new lawn takes root and flourishes.
Soil Testing
Before anything else, test your soil pH. St. Augustine grass needs pH around 6.5, Zoysia needs 6.5-6.8. If your soil is too acidic, lime treatments bring it into range. This step prevents problems down the road.
Weed Treatment
Apply herbicide to kill existing weeds at least 2 weeks before installation. New sod can't compete with established weeds. Roundup or similar products work—just wait the full two weeks before laying sod.
Soil Preparation
Till the soil 4-6 inches deep. Remove rocks, roots, and debris. Grade the soil so water drains away from structures. Add topsoil if needed to reach proper grade. This is the most labor-intensive step but the most important.
Sod Installation
Sod must be installed the same day it's cut—within hours, not days. Stagger the seams like brickwork. Press edges tight together but don't overlap. Roll the lawn to ensure root contact with soil.
Initial Watering
Water immediately after installation until the soil underneath is wet. For the first 10 days, water 2-3 times daily to keep sod moist. Roots establish during this critical period.
Why Soil Prep Matters
Skipping soil preparation is the number one reason new sod fails. Compacted soil prevents roots from penetrating. Wrong pH starves the grass of nutrients. Poor grading creates drainage problems that drown roots or leave dry spots.
Professional installation includes proper soil prep. That's the difference between sod that takes root in two weeks and sod that dies in two months.
Best Time to Install Sod in Jacksonville
Jacksonville's climate allows sod installation year-round, but timing affects establishment. Spring (March-May) and fall (September-November) are ideal—moderate temperatures reduce stress on new sod. Summer installation works but requires more frequent watering. Winter installation is possible since Jacksonville rarely freezes, but growth will be slower until spring.
How Long Until You Can Use Your New Lawn?
Light foot traffic after 2-3 weeks. Full use after 4-6 weeks. Mowing starts when grass reaches 3-4 inches, typically 2-3 weeks after installation. First fertilizer application should wait at least 60 days to avoid burning new roots.
