Dear Lykkers! Cacti are the epitome of low-maintenance plants, making them a favorite among people who might not have the greenest of thumbs.

But just because they’re hardy desert dwellers doesn’t mean they can survive without some care—especially when it comes to watering. So, how often should you water a cactus?

The Desert Trick: Less is More

Cacti come from some of the world’s driest regions, where rain is scarce. In their natural habitat, these plants have evolved to store water in their thick, fleshy stems. The key to cactus care is understanding that they need much less water than your typical houseplant. In fact, overwatering is the number one killer of cacti. So, if in doubt, water less!

How Often Should You Water Your Cactus?

The watering frequency for cacti varies depending on the season, their environment, and their specific type. However, a general guideline is to water them about once every two to four weeks during their active growing season (spring and summer) and much less frequently in the winter.

In winter, many cacti go into a dormant period, where they need even less water—sometimes only once every 6-8 weeks!

Factors That Influence Watering Frequency

Before you set a strict watering schedule, it’s important to consider the following factors that can affect how often you should water your cactus:

1. Type of Cactus

Some cacti require a bit more water, especially when they're flowering. Meanwhile, desert cacti like the Saguaro are much more drought-resistant. Know your cactus species to determine their specific needs.

2. Soil and Pot Type

Cacti should always be planted in well-draining soil that mimics their natural desert conditions. If your pot doesn’t have proper drainage, the water can sit at the bottom and cause root rot. Make sure to use pots with drainage holes and cactus-friendly soil to keep things dry.

3. Size of the Cactus

Smaller cacti may dry out more quickly than larger ones, so they might need watering slightly more often. However, always err on the side of caution—let the soil dry out completely before giving your cactus a drink.

4. Climate and Humidity

Cacti in a hot, dry climate will need more frequent watering compared to those in humid environments. Keep in mind that indoor air can be drier in winter, so adjust your watering schedule if needed.

How to Tell When Your Cactus Needs Water

The best way to know if your cactus needs water is by checking the soil. Stick your finger about an inch deep into the soil, and if it feels completely dry, it’s time to water. If there’s still moisture, wait a few more days before checking again.

Another indicator? Look at the cactus itself! If the cactus starts to look wrinkled or shriveled, it might be thirsty. But be careful—don’t confuse natural ridges on the cactus for shriveling, as some cacti have textured skin.

The Watering Technique: Slow and Steady

When it’s finally time to water your cactus, it’s essential to do it right. Instead of drenching it all at once, water it slowly and thoroughly until you see water draining out of the bottom of the pot. This ensures that the roots have soaked up the moisture they need. After watering, make sure to empty the saucer under the pot to avoid root rot.

How to Water Cacti in Winter

As mentioned earlier, winter is a dormant season for most cacti, so they require significantly less water. In colder months, you may only need to water your cactus once every 6 to 8 weeks. Keep them in a cool spot away from direct heat sources, and avoid watering unless the soil is completely dry.

When it comes to watering a cactus, less is definitely more. By understanding your plant’s needs, checking the soil regularly, and adjusting for climate and season, you can keep your cactus happy and healthy for years. Remember: it's always better to underwater than to overwater. After all, these prickly plants are designed to survive droughts, and a bit of dry soil won't bother them!
