Signs of Cold Temperatures in Garden cress
Symptoms
Garden cress tolerates cool temperatures moderately well, flourishing optimally when temperatures range from 60℉ to 70℉. In colder months, it needs to stay above 50℉. If temperatures drop below 32℉, foliage might darken. Severe cases can lead to water-soaked necrosis, wilting, drooping, and a gradual browning of leaves.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm spot or construct a temporary greenhouse for protection from cold. When inside, position it near a south-facing window for adequate sunlight. If light is insufficient, consider using additional grow lights.
