6 Reasons for Christmas Cactus Leaves Curling

#1. Inadequate Watering

People often assume that a Christmas cactus cannot be underwatered simply because it’s succulent.

However, it’s possible for this aesthetically attractive succulent to be underwatered, which may cause its leaves to curl and shrivel.

There are a number of factors that determine how often a Christmas Cactus should be watered. These factors include:

  • The Season: During spring and summer, Christmas cacti need more water since they exponentially grow and are more active than during the winter.
  • Planting Location of Christmas Cactus: Christmas cacti are grown in small-sized containers that need to be watered more often than those grown in large containers. Also, Christmas cacti grown directly on the ground in the outdoor space must be watered more often than those grown in containers and indoor spaces.
  • Humidity: The humidity of the environment in which these succulents are grown in. Christmas Cacti grown in regions with high humidity should be watered less frequently than those grown in an area with low humidity.

Below are some of the other telltale signs that your Christmas cactus leaves are curling due to being underwatered:

  • Its leaves may become brown (this happens when a Christmas cactus is chronically underwatered)
  • Its leaves become thinner
  • Its leaves feel spongy to touch instead of feeling firm

#2. Root rot

Fungal infection, inadequate oxygen supply in the soil, and overwatering are some of the main causes of root rot in a Christmas cactus.

Christmas cactuses with root rot have their leaves shriveled or curled up.

#3. Temperature and Stress

Temperature stress may cause Christmas Cactus leaves to curl. This succulent may be subjected to either high, chilling, or freezing temperature stresses.

When this plant is unable to cope or respond favorably to any of these temperature changes, it automatically curls its leaves and shrivels.

#4. Pest infestation

Despite the Christmas cactus is relatively pest resistant, it may sometimes become pest infested, which may cause its leaves to curl up and shrivel.

Spider mites, Mealybugs, Fungus gnats, and Scale insects are some of the most common pests known to infest the Christmas cactus.

Spider mites are almost impossible to spot. However, their fine sheet-like webs, which they build between the cactus’s spine, give away these extremely hazardous minute red pests when they infest a plant.

#5. Inadequate Lighting

For a Christmas cactus to thrive, it requires plenty of sunlight. Thus, by not providing it with enough lighting, a Christmas cactus will curl or shrivel.
