How Often To Water Christmas Cactus: Watering Frequency And Technique

How Often To Water Christmas Cactus

Christmas cacti (Schlumbergera spp.) need proper watering to keep the plants healthy and thriving. So, as cactus enthusiast and garden grower, you must know how often to water Christmas cactus to help it thrive.

You should water Christmas cactus once in every 1-2 week during the wet seasons. However, during the drier time, you should water it in every 4 to 5 days.

To determine if the Christmas cactus need water or not, you can check its topsoil, leaf appearance and its growth.

How to Know When To Water Christmas Cactus – Details

Properly gauging when your Christmas cactus needs water is essential. It will prevent both overwatering and underwatering. Look out for these signs:

Signs of Water Requirement Explanation
Dry TopsoilIf the top inch of soil feels dry to the touch, it’s time to water. Avoid overwatering if soil is damp.
Leaf AppearanceWilting or drooping leaves signal water deficiency and stress.
Leaf TextureLeaves become flat and slightly wrinkled when the plant is thirsty.
Leaf ColorIntense green leaves indicate proper hydration, while dull or slightly yellow leaves suggest water stress.
Slow GrowthInsufficient water can lead to slower growth compared to usual rates.

Lets know in detail –

Dry Topsoil

The top inch of the soil should be your main indicator of the plant’s moisture level. Stick your finger gently into the soil. If it feels dry to the touch, it’s a sign that the plant’s root zone is becoming parched and it’s time to water. Avoid watering if the topsoil feels damp, as overwatering can lead to root rot.

Leaf Appearance

One of the most evident signs of a thirsty Christmas cactus is the drooping or wilting of its leaves. If the leaves look limp and are sagging downwards, it indicates that the plant is stressed. This is a clear visual cue to provide hydration promptly.

Leaf Texture

The texture of the leaves can give you insights into the plant’s watering. When a Christmas cactus need water, its leaves might appear slightly shriveled and flattened. They may lose usual turgidity and feel a bit soft to the touch.

Leaf Color

Pay attention to the color of the leaves. A well-hydrated Christmas cactus exhibits vibrant and intense green leaves. Conversely, if the leaves start to appear dull, or if you notice a slight yellowish tinge, it indicates that the plant requires watering.

Slow Growth

Insufficient water can directly impact the growth rate of your Christmas cactus. If you notice that the plant isn’t growing as quickly as it usually does, inadequate water could be one of the contributing factors.

How to Water Christmas Cactus: Step by Step Guideline

Watering your Christmas cactus correctly can make a significant difference in its overall health and well-being. Here’s a step-by-step guide:

  1. Choose the Right Pot: Ensure your pot has drainage holes to prevent water from accumulating at the bottom.
  2. Watering Technique: Thoroughly water the plant until you see water draining from the bottom.
  3. Drain Excess Water: Allow the pot to drain completely, ensuring no standing water in the saucer.
  4. Avoid Standing Water: Empty the saucer if excess water collects there after watering.

Signs of Overwatering and Underwatering Christmas Cactus

Both overwatering and underwatering can harm your Christmas cactus. Look out for these signs:

Signs of Overwatering Christmas Cactus

  • Yellowing Leaves: If the leaves of Christmas cactus are turning yellow, especially at the base, it indicates overwatering. The excess moisture can lead to root stress and hinder nutrient uptake, causing the leaves to lose their vibrant green color.
  • Translucent Leaves: Overwatering can cause the leaves to become translucent or see-through. This is because the plant’s cells are filling with water and becoming overly saturated. It gives the leaves a waterlogged appearance.
  • Mushy Stems: When the stems of Christmas cactus feel soft and mushy, it’s a sign that they are rotting due to excessive water. Healthy stems should feel firm and plump.
  • Moldy Soil: Overwatering creates a damp and humid environment for mold and mildew growth on the surface. For overwatering, you might notice fuzzy white or green patches on the soil.
  • Root Rot: Over time, persistent overwatering can cause root rot. It is a serious condition where the roots become decayed and brown. If you gently remove the plant from its pot and notice dark, foul-smelling roots, root rot is likely the culprit.

Signs of Underwatering Christmas Cactus

  • Wilting Leaves: The leaves of underwater Christmas cactus will start to wilt and droop. This is the plant’s way of conserving water and minimizing moisture loss through transpiration.
  • Shriveled Leaves: Underwatering causes the leaves to lose their turgidity, making them appear limp. They might feel thin and papery to the touch.
  • Slow Growth: A lack of water can slow down the plant’s metabolic processes, leading to sluggish growth. If you notice that Christmas cactus isn’t producing new segments or growing as it should, it could be a sign of underwatering.
  • Dry Appearance: The appearance of the plant will be dry and lackluster. The leaves might curl slightly at the edges, and the plant could appear stressed.
  • Stress and Discoloration: Underwatering leads to stress, causing it to develop a reddish or purplish hue. This is especially noticeable along the edges of the segments.

What Type of Water To Use For Christmas Cactus?

Different water sources contain varying levels of minerals, chemicals, and additives that can influence the well-being of your plant. Here’s a closer look at the options –

Tap Water

Tap water is a readily available water source for most households. However, it often contains chlorine and fluoride, which can be harmful to your Christmas cactus.

Before using tap water, let it sit in an open container for about 24 hours. This allows the chlorine and fluoride to evaporate, reducing their potential negative effects on your plant.


  • Convenient and easily accessible
  • Chlorine and fluoride can dissipate with time


  • Minerals in tap water can lead to mineral buildup over time.
  • Some tap water can have a high pH, which might not be suitable for the plant.

Filtered Water

Using filtered water, such as water from a water purifier or a filtration pitcher, can be beneficial for your Christmas cactus.

Filters can remove some of the minerals and chlorine present in tap water, reducing the risk of mineral buildup in the soil.


  • Reduced mineral content and chlorine exposure.
  • Provides a more consistent and controlled water quality.


  • Filtered water might not be as readily available as tap water.
  • The effectiveness of filtration methods can vary.


Rainwater is a natural and chemical-free option for watering your Christmas cactus.

It’s free from the additives and minerals present in tap water, making it an excellent choice for plants that are sensitive to such elements.


  • Chemical and mineral-free, making it gentle on plants.
  • Provides a more natural water source for your cactus.


  • Collecting rainwater requires a proper collection system.
  • Availability depends on weather conditions.

Distilled Water

Distilled water is essentially pure water, devoid of minerals and impurities.

While it might seem like an ideal choice, prolonged use of distilled water can lead to nutrient deficiencies in Christmas cactus.


  • Free from minerals and chemicals.
  • Eliminates the risk of mineral buildup in the soil.


  • Lacks essential minerals that plants need for healthy growth.
  • Long-term use can lead to nutrient imbalances.

Frequently Asked Questions

1. Can I mist my Christmas cactus to increase humidity?

Yes, misting can help increase humidity, which these plants appreciate, but avoid misting during flowering as it can damage the blooms.

2. How do I repot my Christmas cactus?

Repot every 2-3 years or when the plant outgrows its pot. Choose a slightly larger pot with good drainage, and use a well-draining potting mix.

3. Is it normal for my Christmas cactus to drop some buds?

Dropping buds can occur due to environmental changes, such as temperature fluctuations or sudden shifts in light. Maintain consistent conditions to prevent bud drop.

Final Words

As you pay attention to your plant’s cues, use the right watering technique, and select the appropriate water type, you can provide Christmas cactus with the ideal watering.

These conditions will help Christmas Cactus to thrive and brighten up your home with its stunning display of flowers.
