Selling plants yesterday was a great success!
I arrived way too late to the "wild" flee market, did not got a good spot and had to park halfway on the country-road and had no space to set up the camping-table, so i left after just one hour, but …
I sold out within less than ten minutes and left a lot of sad people behind asking if i really, really, … really(!) have no more plants.
Sold tomatoes, a few peppers, cucumbers, zucchini, butternut, acorn- and buttercup squashes, even three small Rhubarb plants. I was told that the plants were looking so healthy and fresh, much better than the (larger) stuff being sold in the big stores. - I blamed the dux-gold for that. The dux earned three months of cat-food within these ten minutes.

Everybody i spoke with told me to come back next spring with more plants, even got offers to help me with setting up a green-house. The prices i was asking ($2 for a pot, $4 for a tray with six plants) were called very reasonable and folks started ranting about what they'd paid at stores and even at the official market in Charleston.
Definitely a business opportunity i will explore! The patio needs some upgrades this year, better insulation and more lights.
