Millennials aren’t having kids. In 2018, the Centers for Disease Control and Prevention reported the lowest U.S. birth rate on record since it started keeping track of it in 1909, according to LiveScience.

Instead, millennials are opting for a different, less traditional form of parenthood—houseplants.

A new survey from Article and OnePoll found that 70% of millennials call themselves a “plant parent,” meaning they play the parental role for their plants.

That said, about half of those surveyed (48%) are unsure they will keep those plants alive.

The survey asked 2,000 people from the ages of 25-29 about their relationship with plants. The survey found 19% said they’d rather get a root canal than be responsible for a plant. And 67% of those who do have plants said “plant parenthood” is tougher than they expected it to be.

The survey results are not all bad. The New York Post reports that four out of five participants in the survey said that the pressure of taking care of the plant helped them take better care of themselves. And 81% of those surveyed said that they believe having plants in their living space makes them healthier — both physically and mentally.

Good for the people, but perhaps not for the plants, though. Fox News reports that the average “plant parent” has killed seven of the plants they’ve taken into their home.

The main reasons were that people didn’t know enough about how much sunlight or water the plants needed. “Plant parents” didn’t know about proper pruning practices or whether certain plants were meant to be kept indoors or outdoors.

According to Yahoo! News, 75% of respondents said they thought plant parenting was a good test run to see if they were ready for pet parenting, not traditional parenting. Pet parenthood is also an incredibly common path for millennials, Forbes reports.

Millennials accounted for a quarter of the lawn and garden market’s revenue, even though plants are not making as much money as other decorations, Money magazine reports.
