When Does Korean Radish Mature? Harvest Guide

Korean radish, also known as mu, is a type of radish that is commonly used in Korean cuisine. It is a cool-season crop that is typically planted in the early spring or late summer/early fall. The maturity of Korean radish depends on several factors, including the specific variety, weather conditions, and growing methods. Generally, Korean radish takes around 60 to 70 days to mature after sowing, but this can vary depending on the conditions.
Understanding Korean Radish Varieties

There are several varieties of Korean radish, each with its own unique characteristics and maturity dates. Some popular varieties include ‘Chungyang’ and ‘Danver’s Half-Long’, which are known for their fast growth and early maturity. Other varieties, such as ‘Korean Red’ and ‘Japanese White’, may take longer to mature and have a slightly sweeter flavor. Understanding the specific variety of Korean radish you are growing is crucial in determining the optimal harvest time.
Factors Affecting Maturity
Several factors can affect the maturity of Korean radish, including temperature, moisture, and light. Korean radish prefers cooler temperatures, typically between 60°F and 75°F (15°C and 24°C), and consistent moisture levels. It can be grown in a variety of light conditions, but full sun to partial shade is recommended. Weather conditions, such as extreme heat or cold, can impact the growth and maturity of Korean radish, and may require adjustments to the harvest schedule.
Variety | Maturity Days | Temperature Preference |
---|---|---|
Chungyang | 60-65 days | 65°F-75°F (18°C-24°C) |
Danver's Half-Long | 65-70 days | 60°F-70°F (15°C-21°C) |
Korean Red | 70-75 days | 65°F-75°F (18°C-24°C) |
Japanese White | 75-80 days | 60°F-70°F (15°C-21°C) |

Harvesting Korean Radish

Korean radish is typically ready to harvest when the roots are between 1 and 3 inches (2.5 and 7.6 cm) in diameter. The exact harvest time may vary depending on the variety and growing conditions. To check for readiness, gently dig around the plant with a fork, being careful not to damage the roots. If the radish is ready, it should be firm and crunchy, with a sweet and slightly spicy flavor.
Harvesting Techniques
There are several techniques for harvesting Korean radish, including pulling, digging, and cutting. Pulling is a simple method that involves grasping the leaves and gently pulling the radish out of the ground. Digging is a more common method, which involves using a fork to carefully loosen the soil around the radish before lifting it out. Cutting is another technique, which involves using a sharp knife or pruning tool to cut the radish from the crown, leaving a small portion of the stem and leaves intact.
The following are some key considerations when harvesting Korean radish:
- Harvest in the morning, when the plants are at their highest water content.
- Use a sharp tool to minimize damage to the roots.
- Handle the radish gently to avoid bruising or scratching the skin.
- Store the harvested radish in a cool, dry place to maintain freshness.
