Xu Fang did some calculations. Although he only had one mu of land, one mu was equivalent to 666 square meters.
Cultivating the Water Dyed Vine required space for harvesting and periodic watering, so he had to leave clear pathways. By this calculation, only about half the area of the mu would actually be planted.
One ton of Earthworm Manure could cover about three square meters of planting area, so his purchase of 120 tons was definitely more than enough.
To procure Earthworm Manure, he needed to contact an earthworm farm.
Xu Fang searched online, only to find that there were no earthworm farms in Yunhai City. However, the neighboring Tingxi City did have one.
Without hesitation, Xu Fang clicked on the farm's contact number and dialed.
The phone rang a few times before it was answered by a hearty and capable female voice. "Hello, this is Zhang Quanying."
"Is this the Earth Spirit Earthworm Farm?" Xu Fang asked politely.
