The system needed to be overhauled so that entire neighborhoods could be certified, not just buildings. Thatâs why NRDC teamed up with the Congress for the New Urbanism and the U.S. Green Building Council to launch LEED for Neighborhood Development, or LEED-ND, in 2010.
Young newly sprouted plants are called seedlings. They are what  grows directly after germination takes place. These plants then  grow into the adult plants.
The pre-sprout phase is most critical. You must maintain a strong commitment to watering new grass seed. The germination time for grass seed ranges from 10 to 15 days depending on the variety. This is how long it will take to actually see the grass growing. It can be even longer in cooler temperatures. Until this point, the seed, or the soil, must stay moist.
