How Often Do You Need To Water A Cactus?

How To Water A Cactus

Cacti are drought-tolerant plants, and their watering needs depend on their environment, size, and season. Here’s a guide to help you water a cactus effectively:

General Watering Guidelines

During Active Growth (Spring and Summer):
- Water every 7–14 days.
- Allow the soil to dry completely between waterings.
During Dormancy (Fall and Winter):
- Water every 3–4 weeks or less.
- Cacti need significantly less water during this period.
Indoor vs. Outdoor Cacti:
- Indoor Cacti: Tend to dry out more slowly and may require less frequent watering.
- Outdoor Cacti: May need more water in hot, sunny conditions, especially during growth seasons.

Factors That Affect Watering Frequency

Soil Type:
- Use well-draining cactus or succulent soil to prevent root rot.
Pot Type and Size:
- Terra cotta pots dry out faster than plastic or ceramic pots.
- Larger pots retain moisture longer than smaller ones.
Climate:
- In hot, dry climates, cacti may need more frequent watering.
- In humid climates, reduce watering frequency.
Cactus Species:
- Some species, like desert cacti, are more drought-tolerant than jungle cacti.

How to Know When to Water

Check the Soil:
- Insert your finger or a soil moisture meter 1–2 inches deep. If it’s dry, it’s time to water.
Look for Signs of Underwatering:
- Wrinkled or shriveled skin, especially at the base.
Watch for Overwatering:
- Mushy or discolored stems, or roots that smell rotten, indicate overwatering.

Tips for Watering Cacti

Soak and Drain: Water thoroughly until it drains from the bottom of the pot, but never let the cactus sit in standing water.
Morning Watering: Water in the morning so the soil dries out by night, preventing root rot.
Adapt with Seasons: Always adjust watering frequency based on seasonal changes and the cactus’s growth stage.

By observing your cactus and adjusting based on these factors, you can keep it healthy and thriving.

Do Cactus Need Watering?

How To Water A Cactus

Yes, cacti do need watering, but their watering needs are much less frequent compared to most other plants due to their ability to store water in their thick, fleshy tissues. Proper watering is essential to keep cacti healthy. Here are some guidelines on how to water cacti effectively:

Watering Guidelines for Cacti:

Frequency:
- Growing Season: During the active growing season (usually spring and summer), water your cactus more frequently, typically every 2-3 weeks. The exact frequency depends on the size of the cactus, the pot, and the environmental conditions.
- Dormant Season: During the dormant period (usually fall and winter), reduce watering significantly, often to once a month or even less, depending on the humidity and temperature of the environment.
Soil:
- Use a well-draining cactus or succulent mix. This type of soil helps prevent water from sitting at the roots, which can lead to root rot.
Watering Method:
- Deep Watering: When you water, do so thoroughly until water runs out of the drainage holes at the bottom of the pot. This ensures that the roots receive adequate moisture.
- Dry Out Between Waterings: Allow the soil to dry out completely between waterings. You can check by sticking your finger into the soil about an inch deep; if it feels dry, it’s time to water.
Potting:
- Use pots with drainage holes to prevent water from accumulating at the bottom, which can cause root rot.
- Avoid pots that are too large for the cactus, as excess soil can hold too much moisture.
Environmental Factors:
- Temperature and Humidity: Cacti require less water in cooler temperatures and higher humidity. In hot, dry conditions, they may need more frequent watering.
- Light: Cacti in bright, direct sunlight may dry out faster and require more frequent watering compared to those in indirect light.

Signs of Overwatering and Underwatering:

Overwatering: The cactus may appear mushy, the base may become discolored, or the roots might rot. Overwatering is the most common cause of cactus problems.
Underwatering: The cactus may shrink, wrinkle, or develop dry, brown spots. While cacti are drought-tolerant, they still need periodic watering to stay healthy.

Special Considerations:

Indoor vs. Outdoor: Indoor cacti generally need less frequent watering than outdoor cacti because they are less exposed to intense sunlight and heat.
Type of Cactus: Different species of cacti have slightly different watering needs. For example, desert cacti generally need less water than tropical cacti like the Christmas cactus.

By following these guidelines, you can ensure that your cactus receives the right amount of water to stay healthy and thrive.

How To Water A Cactus

Follow our guide below if you are wondering how to properly water your cactus.

Water In Pots

Cacti planted in pots should be watered twice for the best results. Water the pots starting in four-foot sections. Make sure the water fills the pot at its maximum height. After everything is settled, go back and water the pot a second time to ensure a deep and even watering for the soil.

Water Deep And Slow

Watering the cactus deeply and slowly is a technique that works well when the plant is in the ground. Referred to as “deep soaking”, this technique involves a steady and slow dripping from a garden hose. The duration of the watering depends on the plant size, but it typically takes anywhere from 2-6 hours long.

Plant Sizes Count

A cacti that is larger in size and more established will not require watering as often as a smaller plant. The bigger the cactus is, the bigger its storage tank, where water is stored until needed. This means a plant with a larger tank can go quite a bit longer between watering. A larger Saguaro, for instance, can last a much longer time without water compared to a 1-gallon Gold Barrel cactus.

Temperatures Can Impact Watering

You will need to water a cactus more often when in a warmer climate. A cactus in a cooler climate will not require as much water.

Don’t Water Newly Planted Cactus

Plant any new cactus dry, while waiting on any watering. The proper time to water will be based on temperature. For instance, the cooler the climate, the longer you should wait on watering. It’s recommended to wait at least a week to give succulent roots enough time to heal before exposing them to water. All future watering should be done only when the soil becomes dry at the roots.
