The last #GardenSunday hosted by me on Bluesky was August 31st due to inability to draft posts (please don’t suggest adding another app to make Bluesky work better) and dwindling active accounts from St. Louis area. I appreciate everyone who participated in Garden Sunday for 181 weeks on Twitter and then 40 weeks on Bluesky. We had a good run. It was a lot of fun and I learned much from and was inspired by so many gardeners and nature lovers. St. Louis Area Plant and Seeds Sales and Swaps and This Week in Gardening & Nature will continue on this blog and links posted to Bluesky. Should Bluesky make changes, such as ability to draft posts, would consider bringing back Garden Sunday.
