K. Koch ex Matsum. & Hayata 1906
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.
|I chose a few tubers 3-4 cm in diameter. They started to grow in the second week of June.|
|They received a lot of sunlight, water and fertilizer, but they didn't grow much.|
|I took similar size tubers, planted them in a pot and they grew on my balcony.|
|They took off a week later than those in the garden and grew the poorest.|
They were exposed to direct sunlight and the soil often got dry in the pot.
|I chose the 3 largest tubers to let them grow at home on the southern window.|
They began to put leaves the earliest, the first photo was taken on 23rd May.
|The tallest plant reached 56 cm of height, the petiole was 36 cm and the leaf span 46 cm.|
|The top view of the 3 largest leaves||A comparison - plants grown on the balcony and at home.|
|After the season the tuber got as an offset in 2001 was 6 cm in diameter. Didn't it take too long as for 8 years of cultivation?|
|In 2010 I took care only about the largest tuber. It began to grow on the first days of June and it also grew at home.|
|The leaf was 71 cm tall, 65 cm wide, on a petiole 40 cm, so it was much larger than a year ago (56/46/36).|
|After the season the tuber was 60x47 mm and weighed 78g, so it hasn't increased much its size since the previous year.|
