Growth Process

Udo plants grow from rhizomes, which are underground stems that store nutrients and produce new shoots. Here is a step-by-step description of udo’s growth process:

Planting: Udo rhizomes are typically planted in early spring or fall. Dig a hole deep enough to accommodate the rhizome and place it horizontally, covering it with soil.

Shoot Emergence: After planting, udo shoots emerge from the soil within a few weeks. These shoots are pale yellow-green and have a distinctive appearance.

Leaf Development: As the shoots grow, they develop large, heart-shaped leaves with serrated edges. The leaves are dark green and provide an attractive foliage display.

Stem Elongation: Udo stems elongate rapidly, reaching heights of up to 6 feet (1.8 meters). The stems are hollow and become more rigid as they mature.

Harvesting: Udo shoots are typically harvested in late spring or early summer when they are still tender and have not yet fully unfurled. Harvesting should be done carefully to avoid damaging the plant.
