Well, i am Beginner with sowing your own Plants.
I sowed a lot of Iris species last Winter, so Iris kaempferi, setosa, ensata and so on. Well i have a lot of seedlings now in this black 11 Centimeter Pots.
Winter is coming and what would you do with all this small Post. They will freeze trough very fast. I was thinking to build a Plunge Bed. I have no Greenhouse. I used to have Iris in Pots but these where Clay Pots with much bigger diameter and i protected them with a fleece.
I would be very happy to read your solutions. Best wishes, Thomas
