How often to water a cactus — gardening pros spill hydration tips

If you're wondering how often to water a cactus, rest assured this isn't going to be the thirstiest in your plant collection.

This prickly pal is used to thriving in the desert, plus it stores water in its stems, so it does not require frequent sips of H20. It's a rather self-sufficient succulent, but you still want to make sure you know how best to meet its watering needs.

We spoke to an expert about how to care for this specific indoor plant, and when you should reach for the watering can.

Here's how often to water a cactus, according to a pro

When gardening in an apartment and debating how often to water a cactus, we'll tell you this: don't overdo it.

"Cacti thrive on a watering schedule that's less frequent than most plants, typically once every two to three weeks during their active growth periods in spring and summer, and even less during their dormant periods in fall and winter," says Gene Caballero, co-founder of GreenPal.

Caring for houseplants means being adaptable, and in a cactus' case, you'll want to avoid moisture, as it's not really a big fan.

"The key is to let the soil fully dry out between waterings to avoid root rot, a common issue caused by overwatering," Gene adds.

Speaking of soil, you'll want to consider using the best soil for succulents, as a cactus requires a particular type of environment to grow well.

Cacti soil typically includes ingredients such as coarse sand, perlite, and crushed granite, to name a few. The Sill's Organic Cacti Mix is a well-draining selection that is used for indoor cacti. Additionally, Miracle-Gro Cactus Palm Citrus Potting Soil available at Target, caters to the plant's specific needs.

It's not just about how often to water a cactus — it's about where to place it, what to keep it in, and how to check for signs it needs a little TLC, such as yellow leaves, indicating it's been overwatered.

Make sure your indoor cacti are placed in bright, indirect light and warm temperatures. "Remember, the right balance of light, water, and temperature is crucial for maintaining a healthy cactus," Gene adds.

Yes, it's been coined as an easy houseplant, but why not set up your green baby for success with just the right tools? After all, plant parents want the best for their flora.
