"To see what's happened here, nobody would have ever thought this could have happened", Trump said as he visited Paradise, a small community in the Sierra foothills, 175 miles north of San Francisco, where authorities say the remains of at least 71 people have been recovered.
Hundreds of Finns posted under the Twitter hashtag #rakefinlandgreatagain, many posting pictures of themselves in the forest or their gardens with rakes.
Tweeters didn't hold back with his famous "Make America Great Again" red cap sporting the words, "Rake America Great Again" instead. One user joked they cook sausages on an outdoor grill with theirs and another posed with hers claiming she was "off to perform my civic duty".
Veli Pekka Kilimaki, a Finnish defence researcher, tweeted: "I perhaps wouldn't compare Finland and California climate-wise. We don't exactly manicure all of it".
If not from Finland, where did Mr Trump get the idea from?
"We're going to have to work quickly".
"Let's hope he gets us some help", said Couch, who voted for Trump and whose house was among those burned down last week.
"I think that California's been really frightful to him and the fights".
The president initially blamed state officials for poor forest management in exacerbating the fires and threatened to cut off federal funding.
He walked side by side with Paradise Mayor Jody Jones and surveyed the devastation of the once lively-town in person. He remembered telling Trump "We take care of our forests" but doesn't remember speaking to him about raking.
"I mentioned [to] him that Finland is a land covered by forests and we also have a good monitoring system and network", he said. "Remedy now, or no more Fed payments!"
Brown noted Sunday that the fires surrounding the now-destroyed town of Paradise, California, is surrounded by federal, rather than state, forests. This fire in Paradise and Northern California was the worst in the history of California.
"The fire was right over there and they were raking trees, little trees like this, nut trees, little bushes that you could see were totally dry, weeds".
Even before those comments, Trump received a slew of criticism for a tone-deaf response to a state hurting badly from the human and economic impact of its most deadly wildfire in history, and where nearly 1300 people are listed as missing.
