Spring is plenty soon enough to aerate a new pond. If started in early spring when surface water temps are 48F-52F you will not need to use the gradual or slow start up procedure to begin aerating because a new pond has not had enough time from winter to summer and accumulate high amounts of dead organics (usu years) to develop a strong thermocline with associated anoxic water in the deep zone. When the water gets from 64F-70F that is a different story and aeration start up should be more gradual.
