Oatroot

This description was machine-translated.

Description

The oatroot is an ancient cultivated plant with pale, fleshy roots whose flavor some liken to oysters. It is closely related to the blackroot but milder and somewhat easier to use in cooking, as its skin does not stain as strongly.

Care instructions

Sow in April and May directly in the ground in deep, loose soil, as the taproot does not tolerate transplanting. Keep the bed moist and weed-free until the plants emerge, and harvest from October as needed, the roots remain frost-hardy in the soil throughout winter.
