My balcony boxes turned out to be lovely. It’s not a full garden, and it by no means could support me, but it’s lush and green which is pretty much all I could expect from 2 square meters. The top boxes are mainly a flower mix, which look like random meadow flowers such as can be found in Poland. I also have some wild strawberries, garlic and lamb’s lettuce in the top boxes, both of which are thriving (the first strawberry was eaten today).
