One who gathers fresh grasses [may use them] until the moisture has dried up; and one who gathers the dry [ones may use them] until the second rains fall. Leaves of reeds and leaves of grapevines [may be used] until they fall from their branches; but one who gathers the dry [ones may use them] until the second rains fall. R’ Akiva says: All of them [may be used] until the second rains fall.
