My Gladiola has 56.5kg on Saturday and Mott will be back aboard as the 50.5kg in the Newmarket was well below his weight scale.
After Saturday's outing, McArdle is planning an attack on the Group 1 Robert Sangster Stakes (1200m) at Morphettville on April 25.
A Group 1 victory is one thing missing from My Gladiola's CV having run second to Tentyris on two occasions down the Flemington straight at the highest level.
"The Sangster should be a good race," McArdle said.
"She'll get in with 54-½ (kilos), and Jamie can ride her in both races," McArdle said.
"He knows her well and hopefully it will work out better than what her last run did.
"It's four weeks after Saturday to the Sangster. She'll have a trial in between and she should be good to go."
McArdle said it was unlikely My Gladiola would back-up two weeks after the Sangster into the Group 1 The Goodwood (1200m) at Morphettville on May 9.
"She hasn't had a good record of backing up in two weeks, but we'll decide that after she runs in the Sangster," McArdle said.
"If she runs well, she'll probably get put away to get ready for the spring."
