I was strolling through the nursery alleys this afternoon when I saw a well hidden Acer Negundo Flamingo about 1 m. high. Looked for something wrong, a crack or something but found nothing. Bought it finally for 14.90 euros ( 21 US dollars ) I pruned the roots and repotted it for a test in 2/3 vermicompost and the rest sand, vermiculite, small pine, in an Air Pot. Wait and see...
