I have some plants on the balcony. This lime tree is the first one I put there. For almost 2 years. To save space I had to cut off some branches stretching towards the balcony and curve the other ones out of it for the leaves to enjoy the fresh air and the sunlight. Luckily it survives well even it is hot (heat from the sun and from the conditioners). This spring it blossoms quite a few flowers (many more than last year). I am glad when I can bring some nature to the flat above the ground and somewhere in the sky :-).
