In most cases, don't allow your grass pallets to sit for more than 24 hours from picking up to installing, and that's ideal conditions. If possible, choose a cooler, more cloudy day for the lawn installation, as this reduces stress on the lawn. The lawn should be installed as soon as possible after receiving it. Once the grass is harvested, it starts to break down.
The speed at which this occurs is determined by the temperature of the air. The grass ordered in winter will last up to a week on the pallet, but if you install it in the hot summer, it will only last 24 hours or less. Watering the lawn while it's still on the platform won't help. The heat of decay is what will cause the grass to spoil, not the lack of moisture.
How long will grass last on a pallet? On a hot day, freshly mown green grass will begin to yellow very quickly on the pallet due to the heat. After the first day, it will turn pale yellow and turn more intense yellow or brown the longer it stays on the pallet. In the hottest summer months, grass should not be left on the pallet for 2 days. In colder climates, grass will last longer.
Buying grass in rolls makes installation relatively simple; simply unrolling the grass lines placed side by side until your yard is covered. But it's not a good idea to buy grass several days before you intend to install it. During the growing season, especially when the temperature is above 80 degrees Fahrenheit with high humidity, the grass tries to keep growing even after being rolled up. It releases nitrogen, which heats the roll and starts killing the grass as soon as 12 hours after the grass is harvested.
In colder spring and fall weather, you may have three to five days to unwind your lawn before damage occurs. During the cold months, grass can stay rolled for much longer, I have seen 5-7 day old rolls that survived very well in cold climates. On hot days, if the lawn is heating up and starting to break down, unroll it immediately and apply water to release the heat. Hard soil will make it difficult for the grass to grow its roots and provide nutrients and water to the blades of the grass.
If you are installing grass in mid-summer, you should receive your lawn the same day you lay it, if possible. For further assistance with delivering new turf or turf, contact a turf installation company in your local area. If you work with professional lawn farmers like Twinwood Farms, you can be sure that the grass was harvested just before you traveled to your project. Augustine, Bermuda 419, or another variety of turf, you'll need to make sure your land is prepared and ready for turf installation to ensure its survival.
