Succulent vs. Cactus: A Quick Guide for Beginners 

Succulent vs. cactus are often grouped, and for good reason. They both thrive in dry environments, have thick, water-storing leaves or stems, and need minimal care. But while all cacti are succulents, not all succulents are cacti. Confused yet? You’re not alone. In this guide, we’ll walk through their similarities and differences, bust some common myths, and help you understand which is which — whether you’re picking a plant, planning soil, or learning how to care for them.

Are Succulents and Cacti the Same?

It’s easy to assume they’re identical, but the answer to “Are succulents and cacti the same?” is no.

Succulents are a broad category of plants that store water in their leaves, stems, or roots. Think aloe, jade, echeveria, and even cactus. Cactus, on the other hand, is a type of succulent with a particular feature: areoles. These are tiny, round bumps where spines, flowers, or branches grow.

So in the succulent vs. cactus debate: all cacti are succulents, but not all succulents are cacti. Knowing this difference is essential for care and safety, especially if you’re planning to harvest sap or touch the plant regularly.

How to Identify Succulent vs. Cactus?

Here are some clues to help you spot the difference:

Feature	Succulent	Cactus
Areoles	Absent	Present (tiny dots or fuzzy bumps)
Spines	Sometimes (varies by species)	Almost always (from areoles)
Leaves	Prominent in many species	Most cacti have no visible leaves
Stem Function	Primarily for support and water storage	Often handles photosynthesis and storage
Flowers	Small or showy, depending on species	Often large, vibrant, and bloom rarely

Succulent and Cactus Soil: Is There a Difference?

One of the most overlooked parts of the succulent vs. cactus topic is the soil. Both types hate wet roots, so drainage is key, but there are subtle differences. Succulent and cactus soil mixes share similar ingredients: coarse sand or perlite, small amounts of compost, and grit or pumice for airflow.

However, cactus soil is usually grittier and contains even less organic material. That’s because cacti are adapted to arid, rocky habitats. If you’re growing both, cactus soil is often the safer base to start with. Choosing the right succulent and cactus soil helps prevent root rot and keeps your plants thriving in the long term.

Succulent vs. Cactus Care Basics 

At first glance, succulents and cacti appear to have similar low-maintenance needs. And it’s true. They’re both drought-tolerant and love sunshine. But if you’re growing them indoors or trying to troubleshoot problems, understanding their subtle differences can make a big difference.

Light Needs

When it comes to light, cacti are sun lovers through and through. They thrive in direct, intense sunlight. Consider south-facing windows or outdoor areas with full exposure. Some species, like the golden barrel cactus, won’t flower unless they get long hours of direct light.

Succulents, on the other hand, vary more. While many enjoy bright light, certain types, such as Haworthia or Gasteria, prefer indirect light and can get sunburned if left in harsh afternoon sun. So if your succulent’s leaves are turning brown or transparent, it might be getting too much sun, something less likely to happen with most cacti.

Watering Schedule

The classic advice — “let the soil dry completely between waterings” — applies to both. However, cacti generally require less water and can go longer between waterings. For example, a potted aloe might be happy with a drink every 10–14 days, while a saguaro cactus might only need water every 3–4 weeks.

Overwatering is the #1 killer for both, but cacti are even more sensitive to it. Their thick, woody stems store water for months, so a little neglect is usually safer than too much love.

Container Choice

Always use pots with drainage holes, regardless of the type of pot. Standing water will rot the roots faster than you think. Terracotta pots are especially ideal. They’re porous, allowing moisture to evaporate and preventing soggy soil. For succulents that prefer slightly more moisture, you can use ceramic pots, but ensure the soil dries out within a few days.

Fertilizer Tips

Both cacti and succulents benefit from feeding, but in moderation. Use a balanced, diluted cactus or succulent fertilizer once a month during their active growing season (usually spring through early fall). Skip the fertilizer in winter when most plants are dormant. Overfeeding leads to leggy growth, soft stems, or salt buildup in the soil. Problems that affect succulents more often than cacti.

Can Succulents and Cacti Be Planted Together?

Yes, they can — but with a few caveats. Since they have similar soil and light requirements, succulents and cacti can be planted together in a pot or shared in a garden bed. However, balance is key. Some succulents grow faster and need more water than their cactus neighbors. To make it work:

• Choose slow-growing succulents like echeveria or haworthia
• Avoid mixing tropical succulents (like jade) with desert cacti
• Monitor for crowding — cacti don’t like being touched!

If you’re unsure what mix works best, apps like Planteyes can help you ID the exact species and offer tailored care tips.

Conclusion

In a nutshell, understanding the difference between succulent vs. cactus is the first step in giving your plants the proper care. While they share drought resistance and similar growing habits, their biology, structure, and needs are distinct enough to be significant.

Whether you’re wondering “are succulents and cacti the same?” or trying to choose the best succulent and cactus soil, being able to tell them apart helps you grow healthier, happier plants.
