Every year, when the last snow of winter has molten and the trees start showing the first fresh green of spring, my wife gets very, very busy.
Dozens of pots are hauled up from the basement, several hundreds of liters of new dirt are bought, and the gardening shops are visited frequently.
After a couple of month the whole terrace has transformed to a different place with hundreds of flowers.
Good thing we have already installed a watering system :)
