We have milkweed on our bluff to the lake. We allow them to grow during the season for the benefit of the Monarks. We don't want them to completely take over the bluff but, want to manage them to a reasonable number. When can I cut some of them down before they spread the seed or do you have a suggestion on how to manage them. Thanks. Bob
Monarchs in northern states lay their eggs in July and August, so we're almost done with that for this year. I suggest that you pull out any plants that you don't want in mid-September - that's the best way to control the population.
Here is some information that you might find interesting, and thanks for helping the monarchs! https://monarchlab.org/biology-and-research/biology-and-natural-history/breeding-life-cycle/annual-l...
