I’d like to ask you all about cutting pigweed and so on. Thank you.

Ordinary green grass will do, it can be found beside villages and ponds. It is not recommended for children to mow the grass alone. Just mow the grass near your home, preferably before breakfast. Not too hot. You can go home after breakfast. If you are more than ten years old, you can carry a slightly larger basket, and one basket can feed the pigs for a day. In hot weather, pigs cannot just eat grass. They also need to be fed some pig food or something, mixed with food. It’s hot in summer, so they don’t eat much, so they have to get some water for a long time to shower and feed them. It should be better in the mountains. If you don’t know what kind of grass the pig eats, you can mow a few more types of grass the first time to see what kind of grass it likes to eat. Next time, cut off what it likes to eat, and it won't eat what it doesn't like.
