Ep. 222 Monarch Butterfly Conservation: Should You Rear Them Indoors? | #GoodGrowing
Episode 260
In this episode of the Good Growing Podcast, horticulture educator Chris Enroth from University of Illinois Extension explores the adversaries of the monarch butterfly, including the controversial practice of captive rearing.
Although we do not recommend captive rearing, there may be times when it is wanted for educational purposes. Can it be done responsibly? Chris shares best practices for raising monarch caterpillars indoors. Instead of captive rearing, support habitat conservation efforts! Learn how programs like Monarch Waystations and pollinator gardens can help restore critical habitat.
