In 2006-2008 my plants grew as usually, but I thought the mother tuber was growing too slowly.
In 2009 I made an experiment, I cultivated a part of the tubers in garden, a part on a balcony and a part at home.
They were exposed to direct sunlight and the soil often got dry in the pot. |
They began to put leaves the earliest, the first photo was taken on 23rd May. | |
