There is a big difference between “throwing down some sod” and proper replacement of sod grass, or correctly doing installation of Zoysia sod, Bermuda sod or St. Augustine sod grass. And quite frankly you don’t even need to contact any sod replacement company if you just want to throw some sod on the dirt under your tree. You can go to Home Depot and buy sod for $3.00 a piece and be done with tossing it down in less than an hour. If you want proper sod replacement installation done then here is the process we use:
#1 Test the soil.
#2 See if the original Bermuda grass the builder put down died due to lack of sunlight (which is the case 90% of the time). If so, use a quality tree trimming service company to thin upper branches from the canopy and remove lower branches to the desired height.
#3 Spray the existing weeds and soil with a non-selective herbicide killer.
#4 Use a sod cutter to strip out the top layer of dead grass (or even bare soil).
#5 Spread missing nutrients, fertilizer, and sulphur (to lower our high PHs) along with compost and sand to loosen the black clay; then work it in.
#6 Install and level the new sod grass.
As indicated in this list, shade from overgrown trees is the biggest issue we see. And if you don't cure the root cause of the problem (whatever it is, if not this) then your new bermuda, zoysia or St. Augustine sod will be thin, or dead within a year of installation.
