Whether radishes, as a common vegetable, can withstand the effects of low temperatures during the cold winter months has always been a concern for many vegetable farmers and gardening enthusiasts. Radish is a semi-cold-tolerant vegetable with a certain ability to withstand cold, but its tolerance to low temperatures is limited.
First of all, the fleshy roots of radishes have a certain hardiness. According to the data, the freezing point of the fleshy root of radish is about minus 11 or so, as long as the soil temperature does not fall below this temperature, the radish will not be frozen. This means that radishes can still grow safely in the soil under light frost conditions. However, when the temperature drops further, especially when it is close to or below freezing, turnips are at risk of frost damage.
The growth of radishes has certain requirements for temperature. Radish seeds can start growing at 4 to 6 years old, and the optimum temperature for growing is between 20 and 25 years. When the temperature is below 6, the growth rate of radish slows down significantly. Therefore, during the cold season, especially during the frost-prone period, the growth of radishes can be seriously affected.
The management strategy of turnips under frost conditions is crucial. For radishes that have already ripened, they should be harvested in time before the arrival of low temperature and cold snaps to avoid frost damage. For the growing radish, appropriate protective measures should be taken, such as building a simple arch canopy, spraying antifreeze, etc., to improve the resistance of the radish to low temperatures.
It is worth noting that after the radish is frosted, its flavor changes. In some places, the proverb even says "frosted radish race ginseng", because frost makes the radish less spicy and sweeter in taste. However, this change does not mean that the quality of radishes will not be damaged after frost. In fact, frozen radishes will become soft, lose their crisp and tender texture, reduce their nutritional value, and may develop an unpleasant taste.
To sum up, radish does have a certain tolerance to low temperatures, but this ability is limited. During the cold winter months, especially in frost conditions, vegetable farmers and gardening enthusiasts need to take appropriate measures to protect their radishes from frost damage. At the same time, the storage of radishes also requires attention to temperature control to maintain their quality and nutritional value. Therefore, although radish has a certain cold tolerance, it still needs our careful care in extreme low temperature conditions.
