They came from tropical regions. If I left them in the ground in cold winter in Niigata, they would be rotten simply because of cold. So I had to dig them before winter come.
I got rid of other weeds around the Taro beforehand. Perhaps you may think about cutting the stems at this stage. But please do NOT cut them before digging out. Because if you cut the stem first, you will lose the grip to pull and lift up the Taro from the ground.
During summer, I should have added fertilizer and mounded soil up around the roots of Taro. But I had been too busy to do those things because of preparation for the online classes of the fall semester. So the harvest of Taro was a little disappointing this year.
I also dug sweet potato in the same day. The sweet potato I planted was improved one having more sweetness than conventional potato. That simply resulted in much damage on surface of the potato. Larvae of scarab beetle in the ground ate the potato and made a lot of holes and dents. Before I got them, I had thought that I would give my sweet potato to my neighbors. But my sweet potato was so dirty and ugly, I gave up my idea to share my sweet potato with people living around me. Instead, I sent one carton box of sweet potato to my sister who lives near Tokyo.
That grotesque shapes of sweet potato means that I should have cultivate the soil with my hand hoe well.
Although they look ugly on the surface, the taste is really sweet. I am happy with them.
