How Do Beanstalks Grow?

As the bean absorbs water, it expands until the protective skin splits. Oxygen reaches the plant, which helps it use the food packed inside to grow. After the skin splits, look for the roots to emerge. They will grow downward to help anchor the plant in the soil (or in this case, the cotton balls).

How tall can beanstalks grow?

Water well in dry weather, this means every day, or every other day, even on dull days and especially if it's windy. Your plant will grow to 1-3 metres tall. By now it will have grown a huge yellow sunflower at the top of the stalk. Tie it to a strong, tall cane or fence to help it stay upright.
