Remi Cake and skipper Jake Daniels were also on the right track, as Harvest kept the silverware they won in the 2018/19 season, known as the Hampshire Intermediate Cup.
The two clubs were Mid-Solent League rivals last season when they both reached the final.
But since then Harvest has progressed to the Hampshire Premier League and there was a clear quality gap between the finalists.
It was by no means one-way traffic, but Harvest was the stronger of the two teams and had the extra quality going forward.
Harvest has won all of its 21 games completed in 2019/20 before the season cutoff.
They started the campaign by beating Strawberry 1-0 to lift the Billy Hill Cup.
Newer was the goalscorer that day, and it only took six minutes to put Harvest in the lead.
Craig Ralph did well to seize the opportunity, and Newer hit his shot confidently with the outside of his foot past goaltender Kevin Dixey and into the far corner.
Strawberry – beaten three times by Harvest in 2019/20 – could have equalized in one minute, but Billy Cobb shot out from a good position.
Daniels was put in by Ralph in the 18th minute, but Dixey came out quickly to block with his legs at the edge of the penalty area.
The keeper, however, was at fault when Harvest doubled their lead in the 39th minute.
He failed to hold back Daniels’ 35-yard free kick and Newer reacted quickly to shoot the rebound at close range.
Dixey remained the busiest goaltender in the second half, with Strawberry rarely seriously testing Tom Roxborough in the Harvest goal.
Dixey left his line to deny Charlie Deluchi while Luke Steere made a half volley from close range.
The match actually ended in the 68th minute when Cake took off from a corner at the far post.
A great pass ended with Daniels scoring a fourth goal in the finals.
Strawberry had the last laugh, however, when Roxborough beat a fierce effort from Connor Mansfield and skipper Brett Lloyd headed from inside the six-yard box.
Overall, however, Strawberry might have few complaints about the margin of victory.
Daniels, Deluchi and Newer were a constant threat, while Steve Morris and Lee Caldwell were strong at the center of Harvest’s defense.
Harvest boss Ray Ogilvie was able to add a Hampshire Cup on Saturday to the Sunday he won with Co-op Dragons in 2016/17.
He wasn’t the only one doing it – Newer, Ralph, Steere, Deluchi, and Mitchell Cowan were also on that Dragons squad.
Harvest: Roxborough, Cowan, Caldwell, Morris, Griffin, Steere, Deluchi (Martin), Daniels, Ralph (Byrne), Cake, Newer (Davies).
Strawberry: Dixey, Hoare, Backhouse, Lloyd, Maddison, Holt (Fidler), Barnes, Saville, Sergeant (Shrubsall), Mansfield, Cobb (Nowell).
