Rumex crispus aka Curled Dock

Taxonomy

Rumex crispus, also known as curly dock, curled dock, or yellow dock, is a perennial flowering plant in the Polygonaceae family. It is native to Europe and Western Asia. This vigorous plant has a taproot and features pointed, wavy-edged leaves. It produces tall, stiff flowering stems that support a narrow column of small, reddish green flowers. During autumn, the stem and seeds turn a rich brown color and persist through winter. The genus Rumex, to which Rumex crispus belongs, consists of herbaceous plants with rounded, light green leaves resembling those of spinach. The fruit of Rumex crispus is a recognizable achene with three membranous wings, grouped in clusters. This plant prefers heavy and clay soils, neutral to acidic pH levels, and humus-rich conditions. It can be grown in pots on windowsills or in open soil, both in ornamental and vegetable gardens. Providing a semi-shaded spot is ideal. Seeds can be sown in nurseries from March to June or in the garden after the last frosts, with a 1 cm layer of potting soil covering the seeds. Regular watering is necessary to keep the soil moist for the seedlings.

How to care for Curled Dock

Difficulty

Curled Dock is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Curled Dock should be watered regularly, allowing the soil to dry out between waterings.

Soil

Curled Dock loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Curled Dock prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Curled Dock to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Toxicity

Curled Dock is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Fertilizer

The Curled Dock should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Growth-pattern

New growth will sprout from the top of the plant as it grows upwards.

Region of origin

Curled Dock’s native range is Most of Europe, including Britain, to N. Africa.
