Final answer:
The Three Sisters is a farming technique that involves planting corn, beans, and squash together to support each other's growth.
Step-by-step explanation:
The "three loving sisters" refers to a farming technique called the Three Sisters, which involves planting corn, beans, and squash together in a small mound. This method was used by Indigenous people in North and Central America and is a form of intercropping, where different plants support each other's growth. The corn provides a structure for the beans to climb, the beans fix nitrogen in the soil for the other plants, and the large squash leaves shade the soil, reducing weeds and conserving moisture.
