Even though you can enjoy a quality lawn in Orlando either with seed or sod and the site preparation for either of them is quite similar, there are some differences in buying, storing and maintaining them.
Sod for soil stabilization eliminates both the seeding and mulching operations and it has its advantages regarding adequate cover and sediment control. However, compared to seed, sod is more difficult to obtain, transport, and store.
Probably the most important factor is the money. Take into consideration that the price of sod varies between $0.50-$1.00 per square foot, with installation running between $150 and $300 per pallet.
Grass seed costs about $0.01-$0.02 per sq ft, while installation prices differ according to the method used. Installation can be made by spreading the seeds with rotary spreaders or it can be blown out of a hose. Either way, the professional installation is cheaper for seed than sod, as there are not so many materials involved and the work itself is easier. Also, a homeowner can prepare and plant grass seed on his own lawn, but it is better to hire a professional to lay sod, which has to be installed the same day it was cut for it to be healthy.
Probably one of the best things about sod is that it will take less time to get you perfect beautiful lawn and that you don't have to worry with weeds, as it is an instant lawn. In about two weeks you can walk on it and use your new lawn at maximum. With seed, it will take some weeks or even months before your lawn looks ok and can be walked on. If money is not a problem, go with sod.
Other reasons to consider seed include the wider array of grass varieties to choose from, and the ability to cover hard-to-reach sites such as steep slopes. And it might also be important that you won't import any potentially troublesome non-native soil either.
Seeded lawns are preferred for the north, where there are hot summers and cold winters. Bluegrass and rye are good types of grass seed for lawns. In the south, where St.Augustine grass, Zoysiagrass and Bermuda are popular turf, is better to use sod for establishment. If you seed your lawn and it rains, the germination pattern can end up being quite irregular, and you may need to seed again several times.
