Symptoms of low temperature injury of flowers and plants, how to do low temperature injury

When flowers are slightly damaged by low temperature, herbaceous flowers appear discoloration, necrosis and spots on the surface; woody flowers also appear bud withering, broken skin, glue and fallen leaves. When the flowers are seriously injured by low temperature, the leaves of grass flowers become soft in the form of water stains, then fall off, and even the plants die; the young buds of woody flowers turn black, the buds and petals change color and fall off, and even lead to branch death or root injury.

For flowers with mild or moderate low temperature injury, they should be moved to absolute light avoidance, about 100C medium temperature environment, and then slowly heated to gradually restore their growth. Do not immediately move the plant to a place with sufficient light and high temperature, otherwise it will lead to plant death. Because the ability of plant growth and development has been impaired, it needs a process of recovery. Flowers damaged by severe low temperature are generally irreparable.
