How to deal with the cold of evergreen

After being taken out of the house in early spring, the evergreen should be placed in a shaded shed or under the eaves or in the shade of the balcony, and be careful to prevent it from getting wet in the rain. In addition to keeping the soil moist in the summer, watering should not be too frequent in spring and autumn, and watering should be controlled in winter. Dieffenbachia has fleshy roots, so it is most afraid of waterlogging. If it is watered too much, the roots will easily rot. However, the air must be kept moist. If the air is dry, undesirable phenomena such as dry leaf tips may easily occur.

When the temperature is below 5 ℃ in winter, Dieffenbachia is very susceptible to cold damage, and will die if not managed in time. So what measures should be taken when suffering from cold damage?

Slight cold damage

The leaves lose their luster and droop as if they have lost water. At this time, the Dieffenbachia should be moved to a place with higher temperature so that it can gradually return to normal. Be careful not to let the temperature rise suddenly after the plant is damaged, to prevent the leaves from wilting.

Mild cold damage

In addition to drooping, the leaves of Dieffenbachia will also develop cold damage spots that resemble scalds from boiling water. When dealing with it, cut off the cold spots on the leaves and move the flowers to a warm place.

Moderate cold damage

Cold spots appear on most of the leaves of Dieffenbachia, and water-soaked patches appear on the petioles and the leaves lose their green color. At this time, the leaves and petioles should be cut off, and the wound should be smeared with wood ash or coal ash. Then put it in a warm place and control the watering appropriately to allow it to slowly return to normal.

Severe cold damage

The new leaves on the tender branches lose their green color and appear as water-soaked patches, while the underground roots are affected by the cold and rot.

Remedies

Dig up the plants in time, remove the underground parts, cut off the affected branches and stems, smear the wounds with wood ash, store them in moist sand, and do cuttings in spring. If severe cold damage occurs and spots appear all over the plant, there is little hope of saving it and you should consider replacing the flowers.
