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.

In this episode of the Good Growing Podcast, hosts Chris Enroth and Emily Swihart are joined by horticulture educator Ryan Pankau to unpack a 2024 study from the Illinois Natural History Survey. The topic? Chemical trespass—how herbicides and other pesticides are drifting into Illinois’ natural areas and impacting native ecosystems, impacting a keystone group of trees - oaks.

10:16:15 What is chemical trespass?
12:58:18 What organizations conducted this study?
16:49:15 What type of data was collected? What species seemed to be most impacted?
19:14:23 What is the ecological impact of pesticide trespass in our forests?
24:30:24 Does this just impact trees on the edges of fields or throughout a forest?
25:20:02 What did the data show in the collection samples?
27:31:09 What was the percentage of chemical trespass observed?
29:56:00 Can we solely rely on visual assessment to determine levels of herbicide trespass?
33:32:06 What they didn't find much of - dicamba and neonics
34:46:00 What does a tree that has been impacted by herbicide drift look like?
40:32:17 The importance of the lab tests in this study.
41:02:16 What do you do when your tree is impacted by herbicide trespass?
48:50:01 Can you prevent this damage or is there a way to protect trees and gardens from being damaged?
56:51:03 While there seemed to be a big focus on herbicide trespass, the study found a lot of fungicide in the later season samples. What is the impact of fungicide?
