How many seeds do you need to grow a full grown cotton bush?

You only need one seed to grow a full-grown cotton bush.

Cotton plants are grown from seed, just like most other plants. Each seed has the potential to develop into a single plant.

However, the number of seeds you might need to get a full-grown cotton field is much higher, as cotton plants are usually spaced out for optimal growth. The exact number depends on the size of the field and the planting density desired by the farmer.
