How Often to Water Christmas Cactus: A Comprehensive Guide

Welcome to our guide on how often to water your Christmas cactus! This popular houseplant, also known as the Thanksgiving cactus or holiday cactus, is a favorite during the festive season. But, despite its beauty, many new plant owners often have trouble caring for it. Overwatering or underwatering the Christmas cactus can lead to wilting, dropping of leaves, and even death. Therefore, it is crucial to understand the watering needs of this plant.

The Importance of Watering for Christmas Cactus

Before we dive into how often to water a Christmas cactus, let’s take a look at why watering is so important for this plant. The Christmas cactus, like other cacti, stores water in its stem, which helps it survive in low-water environments. However, it needs a consistent and balanced amount of water to thrive.

Watering helps to keep the plant hydrated, which in turn affects the health of its leaves and flowers. Overwatering can cause the roots to rot, leading to fungal diseases. On the other hand, underwatering can cause the leaves to wither and drop off. Therefore, it is essential to find the right balance and know how often to water your Christmas cactus.

How Often to Water Christmas Cactus: Factors to Consider

The frequency of watering your Christmas cactus will depend on several factors, including:

Factors How It Affects Watering Frequency
Temperature The warmer the temperature, the more often you need to water your Christmas cactus.
Humidity High humidity can mean less frequent watering.
Type of soil A well-draining soil mix will need more frequent watering.
Size of pot A larger pot means less frequent watering.

The Right Time to Water Christmas Cactus

Before watering your Christmas cactus, ensure that the soil is dry to the touch. Insert your finger into the soil up to the second knuckle. If it feels moist, wait a few more days before watering. If it feels dry, water the plant.

How Much Water to Use

The amount of water you use will depend on the size of your pot. In general, use enough water to moisten the soil without making it soggy. Avoid letting water stand in the drainage tray, as this can cause root rot.

Watering Frequency for Different Seasons

The watering frequency for your Christmas cactus will vary depending on the season:

Spring and Summer:

During the growing season, which is from spring to summer, the Christmas cactus requires more water. Water the plant once every week. If the temperature is high, increase the frequency to twice a week.


In the fall, reduce the frequency of watering to once every two weeks. This is the time when the plant prepares for blooming.


During the winter, water the Christmas cactus once every three weeks. This will help the plant conserve energy for its next blooming cycle.
