If there is really no manure, use manure or manure, which belongs to farm manure. Please believe me, just watering is not enough. I majored in biology. Although I am only a high school student, I have learned these knowledge.

Hope to adopt

Remember: persevere.

It doesn't matter if you don't give me points. Time will tell.
