If you will install sod now, it will take root and just hibernate when it snows in winter.
Next spring, as soon as the snow will clear, your sod will already be well planted. You will not have to wait for the sod harvest season to begin. The sod in your lawn will be ready and waiting to grow back to the lush green lawn you always want on your property.
So don’t wait for next spring/ summer. Now is the best time to buy sod for your lawn.
