My 4th plant, sowed last summer, was transplanted to the larger pot. Because of my living environment, I could not get enough sun light to the plant for a couple of months in this summer. Also, long rainy days in July, the plant has lost all of the leaves grown since last year, and only with the new ones from this spring.
I used the ordinary planting soil from nursery section of home center (DIY store) and mid size clay based soil for better drainage, also some compost and my home made organic fertilizer mainly consisting from rice bran.
At the end of transplanting, I covered the soil with bark chips to prevent over dry as well as packing the soil by watering.
