Summer Heat Returns + First Migration Monarch Emerges
Happy Sunday Good GROWer,
summer has returned to the bold north with 80ās, heat, and humidity. š
This is perfect weather for migration-generation monarchs looking to fuel up before making the long migration south š¦ š²š½ā¦but has the migration already passed us by in ā25? š¤
As Iāve mentioned before, we are shutting down our raising supplies shop. At this point, Iāve finished moving over necessary content from the shopify store to the wordpress blog. This means we now have a shop shut down date coming up next weekā¦
September SHOP Farewell š
Our shop is permanently shutting down on Wednesday, September 17th, 2025.
As you might have noticed, most of the supplies are sold out but you can still buy these supplies while the shop is still up ands running. We pay shipping on all shop orders $50+
Little hole lids ā¬ ļø only buy these IF you already own our āfat catā floral tubes ⬠ļø, which are almost sold out. These alternative lids are for thin-stemmed cuttings to prevent baby caterpillar drownings
Garden for Life Pollinator Garden Flags ā¬ ļø (20% OFF and a good gift idea for the upcoming holidays!)
Raising Butterfly and Milkweed Quickstart Guides ā¬ ļø (instant PDF downloads: save an extra 15% when you bundle with lids or flag)
Thank you for all your support over the past decade. š Donāt worry, Iām not giving up on supporting monarchs and other beneficial pollinators and will still publish a newsletter and the monarch butterfly garden blog to help you achieve these goals.

Raising Report
We currently still have 9 caterpillars and 5 chrysalides, and one newly emerged female monarch this morning!
I brought in one instar 2 this week, but not sure how the count jumped from 13 to 15 totalā¦for the first time in raise the migration history, I messed up the initial count or unknowingly brought in an extra catā š I donāt normally count caterpillars brought in (during Raise The Migration) because they can be parasitized outdoors...since this last caterpillar was pretty small, hopefully it went undetected by tachinid flies.

Last Minnesota Monarch 2025
The worrisome emails have already begun as we approach mid-Septemberā¦.is it too late for monarchs to migrate?
NOT Too Late to Migrate
Let me calm some frazzled nerves with these late-season facts:
In Minnesota, weāve released monarchs through the first week of OCTOBER without issue
In Minnesota, Iāve seen monarchs still fluttering south (in Minnesota) during the last week of OCTOBER š
There have been reports of monarchs entering the sanctuaries in Mexico as late as DECEMBER
Monarchs can fly hundreds of miles a day ā¬ ļø (if necessary)
Monarchs can fly in temps as low as 40ās, if thereās sunā¦I have witnessed this with my own eyes! š
So, at this point in time, thereās absolutely no reason to worry about whether monarchs can still migrate from your region. If it does get to cold, monarchs can serve the ecosystem in other ways as food for predators. If they all survived, you would not have a healthy ecosystem to support them.
If youāre raising migratory monarchs, make sure you give them the best chance to successfully join their monarch mates down south:
šæ Garden PLANT Report šŗ
My plan was to show more late pollinators in video-form this week, but itās still been relatively quiet here with a max of 5 monarchs in the garden at one timeā¦this is the lowest number for āpeak migrationā I can recall seeing in our garden, but Iāve heard a few reports that there are more monarchs north of us. Hereās our glorious stand of Mexican sunflowers, going largely unused this migration season:
My gut is telling me weāve been bypassed because of the early cool spell this year, but Iām still holding out a little hope we could see a few more migrators this coming weekā¦
I hope you are seeing more monarch activity in your region!
Besides Mexican sunflowers, purple giant hyssop, verbena bonariensis, and zinnias are still in prime condition to support late-season pollinators and new england asters are starting to unfold their late-season brilliance.
Past peak: goldenrod, liatris
Coming Up Next?
We will discuss fall planting to see which perennials you can add now, to start improving upon your 2025 garden. š§āš¾šŖ“š©āš¾
Until next time,
