Introduction: Curly dock, also known as yellow dock (Rumex crispus), is a versatile and resilient perennial plant that belongs to the Polygonaceae family. Widely distributed across North America, Europe, and parts of Asia, this hardy herbaceous plant is known for its distinctive curly leaves, which give it its common name. Cultivating curly dock can be a rewarding experience for gardeners and herbal enthusiasts alike. In this article, we will explore the cultivation process, requirements, and the various uses of curly dock.
Cultivation Requirements:
Climate and Soil:

Propagation:

- Start seeds indoors in late winter or early spring, and transplant seedlings outdoors once the danger of frost has passed.
Planting:
