During the spring and summer times we recommend that a pallet not sit on a pallet for more than 24 hours. It is important to lay your new sod as soon as possible so its root system has plenty of time to plant into its new home. During the fall and winter times we still recommend that you lay your sod as soon as you can for a higher survival rate, but if you have to allow your sod to sit on a pallet for a day its survival rate is still very high.
