Short-term thinking can create long-term headaches.

In the rush to complete a construction project, details are often sacrificed. Sodding can provide an “instant” lawn, but site preparation is critical to long-term success. Preparing a lawn to be sodded is much the same as it is for seeding. Construction debris should be removed from the area. Construction compaction must be alleviated with cultivation such as roto-tilling followed by grading and leveling. If you choose to amend clayey soils, do not use sand or gravel. The end result may be a tighter soil than the original. Instead, add organic material such as compost or peat and mix as thoroughly as possible. Post-sodding care is important as well. Sod needs light frequent irrigation at first to keep the sod from drying out in the heat of the afternoon. As the sod begins to root into the soil, irrigation should shift to deeper and more infrequent. Many sodded areas can benefit from the addition of spring and fall core aerification once the sodded is well rooted.

Preparing a site for sodding is at least as important as laying the sod itself.
