It's crazy, right? I was stunned as well. They're also called a Yardlong bean, snake bean, asparagus bean, and Chinese long bean. Haha, so many names. It is true, it could make a whole meal, quite economical. It's common here in the Philippines, it can withstand humid heat. I caught grasshoppers around it thrice.
I was uncomfortable repotting as well, more of being afraid of any squiggly that might be hidden in the soil. I don't usually wear gloves so there's always that jump and shriek element of surprise Lol It's a hit or miss, sometimes plants don't like being transferred, it happens. Hopefully, the fertilizer works out.
