Potting Up Zinnia Seedlings In Vertical Garden - July 2025

The flats of Zinnias that I planted from seed have been hanging around on our patio for weeks.  Ready to pot-up into their final destination.   I grew three varieties this year - Envy, State Fair and Cut-and-Come-Again in eight-cell recycled containers that I scavenged from some annuals.  I was waiting for the Zinnias to put on multiple sets of 'real leaves' before transplanting them, but then I got busy and probably waited to long. 

Here are some photos of the process - from cells to Greenstalk vertical garden.  This is a tiny example of "Flower Farming" in a small space with vertical gardening beds. Last year, I grew a number of Zinnias in this Greenstalk successfully.  This year, I'm leaning into it way more.  They started to bloom in late August last year - after being direct sown.  

This post is going up in July, but this process happened at the end of June.  This is about two weeks ago.  

I added in some new potting soil to each of the Greenstalk trays.  And then tucked in a tiny seedling into each one.  With six openings per level, I filled five levels = 30 Zinnias.  Will all of them make it?  Not sure.  But, if they do, we'll be LOADED with Zinnia flowers later this Fall.

Here's a look at one of the levels of the Greenstalk:

Here, below, is a peek at the Seedlings all potted-up.  I'll have to continue to rotate this vertical garden (and water it), so everything grows evenly and doesn't get neglected.
