Yellow restharrow

Also known as: Large yellow restharrow

Yellow restharrow (Ononis natrix), native to Europe and the Mediterranean, produces bright yellow, bonnet-like flowers. The name "restharrow" is given in homage to the plant's tough root system, which if not cleaned from agricultural land, can stall the progress of the harrow, a tool used to break up the earth after plowing.

Water: Yellow restharrow thrives in arid environments, exhibiting high drought tolerance and requiring watering once every 2-3 weeks. Best suited for outdoor cultivation, it flourishes when soil dries out between waterings, adapting effectively to regions with sporadic rainfall.

Fertilize: Fertilize yellow restharrow quarterly with balanced fertilizers, using high-nitrogen types during spring/summer for optimal growth. Apply cautiously to avoid over-fertilization and chemical burns. Adjust application based on plant size and growth stage, ensuring even distribution and following product guidelines for optimal care.

Pruning: Yellow restharrow features bright yellow flowers and thrives in dry, sandy soils. Prune in early spring to remove dead branches and spent blooms, promoting healthy growth and prolonging flowering. Avoid heavy pruning to maintain its bushy form while using sterilized tools to minimize disease risk.

Propagation: Yellow restharrow propagates well through cuttings taken from healthy, semi-woody stems. Applying rooting hormone boosts root growth, while using a moisture-retaining yet well-drained medium prevents overwatering. Keeping cuttings in a warm, indirect light promotes optimal conditions for successful root development.
