Looks like you have a ways to go before spring comes around there in Lithuania. Same here, my iris are not doing much of anything. Not really growing much for spring. In fact they are mostly sorry looking.
Late last summer, about the end of August, I moved an entire Iris Garden bed from my square raised garden to a section over near my garage near the property fenceline. So I am hoping they look really good there. They did have plenty of time to settle in and grow before winter. I needed that square garden for tomatoes as I decided to grow tomatoes and beans there this year. I know, not anywhere near as pretty but yummy to eat.
