Aston Villa are currently 10 points away from safety after making an awful start to the season.
Although the French boss understands why there is an air of frustration around Villa Park at the moment, he has called for unity from the supporters.
Garde wants Villa fans to support their team, as he feels their backing could be crucial for the club to get out of trouble in the second half of the campaign.
“With our fans, I totally understand their frustration because we are bottom of the league and we don't win games,” he said.
"But without this support it's more difficult for the players, the club and all the team.
"During the game you never know - even if you are one goal down, maybe you can score two at the end of the game before the final whistle.
"We need to be altogether - the fans, the players - because the situation requires that. You cannot afford to behave differently."
Villa Park is understandably not a happy place at the moment, given their side’s struggles since the summer.
The Villans have failed to win any of their last 15 Premier League matches, and they are currently 10 points away from safety with many of the sides above them showing signs of improvement.
Villa’s performances have been well short of the standard required, and they lost 2-0 to Arsenal in their last outing in front of their own fans without posing much of a threat to Arsene Wenger’s men.
Villa’s next home match comes against West Ham United on Boxing Day, before they take on Norwich City at Carrow Road on 28 December in a match they really need to win to get some confidence heading into 2016.
