To revive frost-damaged plants in your greenhouse, start by assessing the extent of the damage. If only the outer leaves or stems are affected, trim them off to prevent any rot and allow the plant to focus its energy on healthy growth. Move the plant to a warmer, more sheltered part of the greenhouse to help it recover.
Ensure the greenhouse is properly insulated and heated to prevent further exposure to cold. If the soil is frozen, water the plant with lukewarm water to help thaw the roots, but avoid overwatering, as this can stress the plant further. Monitor the humidity and airflow to prevent mold or fungal growth. For some plants, cutting back on watering temporarily can reduce stress. Providing additional light with grow lights can also help promote recovery, especially if natural light is limited.
