What to do if Dieffenbachia is damaged by frost

Frost damage of Dieffenbachia

Frost damage is a phenomenon that easily occurs in winter. The suitable maintenance temperature for Dieffenbachia is between 25℃ and 30℃. Its cold resistance is relatively poor. When cultivating it, if the temperature is too low, it is easy to suffer from frost damage.

Generally in winter, when the temperature is below 5℃, Dieffenbachia is prone to freezing and death.

Slight frost damage to Dieffenbachia

This situation means that the variegated dieffenbachia has suffered frost damage, but the degree of damage is relatively light. The leaves will lose their luster, lose water and droop.

When this happens, you can place the Dieffenbachia in a place with relatively high temperature to allow it to recover slowly. Note that the temperature should rise slowly, and not rise too quickly all at once, as this will be detrimental to the growth of the Dieffenbachia.

Slight frost damage to Dieffenbachia

The variegated dieffenbachia is more obviously affected by frost, with its leaves drooping and frostbite spots appearing on the leaf surface. At this time, you can use scissors to cut off the frostbitten parts of the leaves of the Dieffenbachia, and then place it in a warmer place.

Dieffenbachia moderate frost damage

Moderate frost damage is actually very dangerous for Dieffenbachia. At this time, a large number of frostbite spots appear on the leaves of Dieffenbachia, and the affected area will also extend to the petioles.

At this time, you can cut off the variegated evergreen together with the petiole, then smear the wound with wood ash, etc., place it in a warmer place, and control the watering.

Severe frost damage to Dieffenbachia

When the Dieffenbachia has been severely damaged, there is little hope of saving it. At this point, not only is the plant obviously damaged, but even the roots underground may have been frozen. At this time, you can directly take out the entire plant of the Dieffenbachia, cut off the affected branches and roots, disinfect it, store it in moist sand, and then carry out cuttings in the spring. But the whole plant has been severely frozen and may not be able to be saved, so I'll have to buy a new pot.
