Succulents are a popular group of indoor houseplants due to their easy care requirements and interesting shapes. Some of the strangest plants are in the succulent family, and they can be quite a conversation piece.

They come across as being almost artificial due to how slowly they grow. Find out more, including just how fast these slow-poke plants can grow.

How Fast Do Succulents Grow (And How to Grow Them Faster)

What are Succulents?

Before we can start talking about how fast succulents grow, you need to understand exactly what type of plants you find in this group. Generally, succulents are dry-climate plants that have very fleshy leaves, spears or rounded bodies.

As I mentioned in this article about succulents vs. cacti, people often mistakenly consider succulents and cacti to be the same thing.

Succulents are a much larger group of plants that does include the spiky cactus family, but also includes things like the jade plants and aloe vera, which are definitely not cacti.

How Fast Do Succulents Grow?

Since this is a pretty big group of different plant species, they don’t all grow at precisely the same rate. To be technical, all succulents grow fairly slowly when compared to other plants.

You also have to take the season into account. Most succulents will have a dormant period in the winter months when growth slows down quite a bit. In fact, it often seems like they stop completely until the longer days and warmer temperatures perk them back up again.

Whether you want a fast-growing plant to keep things more interesting, or a slow-growing one (let me show you how to keep them small) because there is less change to deal with, there is a variety out there to suit.

First, let’s take a look at a list of fast growing succulents. These would be plants that you can usually see some growth over the course of a month or less. There will be significant size increase in 4 months.

  • Irish rose (Aeonium arboreum)
  • Hen and chicks (Echeveria sp.)
  • Jelly bean plant (Sedum rubrotinctum)
  • Jade plant (Crassula sp.)
  • Haworthia (Haworthia sp.)
  • String of buttons (Crassula perforata)
  • Lavender scallops (Kalanchoe fedtschenkoi)
  • Aloe vera (Aloe vera)
  • Christmas cactus (Schlumbergera sp.)

And for those who prefer even more sedate houseplants, there are the slow growing succulents that often give the impression that they are not growing at all.

  • Living stones (Lithops sp.)
  • Air plants (Tillandsia sp.)
  • Crinkle leaf plant (Adromischus cristatus)
  • Barrel cactus (Ferocactus sp.)

Lithops

Now these are just both ends of the spectrum. There is a large variety of succulents that fit in the middle and that grow very well as houseplants.

Other varieties of Sedum and Kalanchoe besides what we’ve already mentioned are great, as are Euphorbia species.

How Big Do Succulents Get?

This is a bit of a tough question to answer since we’re talking about such a large group of plants. Some will stay small enough to stay perched on a window sill, and some will get to be several feet high. In the extreme, you can find saguaro cactus that reach 40 feet or more.

Not all issues with size are about height though. Many succulents reproduce by sprouting little buds, that would normally break or fall off when out in the wild. They put down roots and a new plant begins.

In a house plant, they tend to stay clustered at the base of your succulent, adding to its girth or width as it grows. You can keep this under control be cutting away the new buds, and either potting them on their own for new plants or just disposing of them if you don’t have the space.

I teach you how to propagate your own succulents in this guide.

Succulent Care

As I cover in my indoor succulent care guide, if you want your succulent plant to grow well, you need to provide it with the best care you can. That means understanding how these plants grow and what they need. Though considered easy to care for, that doesn’t mean they don’t have some specific needs.

The biggest requirement that these plants have is lots of bright sunlight. If you don’t have a window that will supply at least 6 full hours of direct light, you won’t have a lot of success with succulents unless you add an electric lamp or two.

With too little light, succulent plants will start to stretch out and get taller as well as thinner. It’s a key sign that they need more sun (see why in my article about what happens to plants without sunlight).

Kalanchoe Succulent

Because succulents like dry conditions, people tend to neglect their watering chores. Just because they like dry soil, doesn’t mean they don’t need water. All that water they hold in their fleshy leaves has to come from somewhere.

When the soil has completely dried out, give them a thorough soak. Leave the plant alone for a few days, then give it another heavy watering. The soil should be very well-draining so the roots aren’t sitting in water.

Now you can leave it until the next watering. On average, it can be a week or more between watering, or even as little as once a month during the dormant stage of winter.

Using unglazed ceramic or terra cotta pots is best for succulents because they allow water to evaporate out of the soil a little quicker. That helps to create the dry environment they need, and protect against water-logged roots.

While they do work very well as houseplants, most succulents will grow faster if they are kept outdoors due to their need for so much sunlight. But since most require very warm and dry conditions (usually zone 9 or above), not everyone has the right local climate.

One little trick to remember is that the succulents that are green will do best inside. Any varieties that come in orange, purple or red really should be kept outside to thrive well.

Long-Term Commitment

As with most slow-growing plants, succulents have a tendency to live for a very long time (see my post that explains what you can expect). While you’re not committing to the same level of responsibility as getting a new puppy, you should know that some cactus species can easily survive for decades, if not to over a 100 years.

Sometimes their appearance changes so slowly, you can’t even tell anything is going on. How can you tell when your succulent has finally reached its final size?

Well, most species of succulent will keep on growing for most of its life, which is why some of the long-lived ones can get so huge. Chances are, if its still living then it is still growing.

  1. Will a succulent left outdoors grow quicker than one indoors?

    • Good question! Generally, a succulent will grow more quickly, and do better in general, outdoors since this is its natural habitat. It really depends on the environment where you live, but generally speaking, an outdoor plant will receive more sunlight and airflow than an indoor one, leading to better growth and overall health.

    what month should i put my succulant outside? I live in NC

    • Good question! It depends on the type of succulent, but most can handle low temps of 30s to 40s F. Here in Michigan, we still have some potential freezing nights ahead of us, but you might be okay in April in North Carolina. Wait until May if you prefer to play it safe.

    Hi there, I just bought some succulents today and I was so excited to repot them. I barely soiled them out (because I didn’t read the directions) and transferred them to a new pot with other succulents as well. Should I pull them out tomorrow and soiled them out and plant again? Thank you

    • Hi Rexxie!

      Great question. When you replant succulents, it really is best to get as much soil out as possible without damaging the roots. The soil that is used for succulents when you first purchase them is dense and tends to hold a lot of water, which can damage the roots. If you don’t feel like you got very much out when you did it before, you may want to repeat the action. Just be careful with them, as transplanting is always a shock. Good luck! I hope the little fellas grow nice and strong for you!

    hi I have bought some succulent seeds for my hanging terrarium in my hot tub summer house I intend on a ceiling of succulents and was wondering what is the best month to start sowing the seeds please I live in the uk but have a conservatory which in intend on using as a growing room its warm and very bright any advice would be a great help

    • Hi, Lolly-pops!

      A ceiling of succulents sounds amazing! At this point (late June), you should be able to sow the seeds at any time. A bit of temperature fluctuation and the bright light within the conservatory should be more than enough to help them germinate. Give it a try, and good luck!

    thank you very much for your help I forgot to ask when they have grown enough to transplant into bigger pots what mix or growing medium would you suggest please as you can tell I’m a novice at this but trying to get there

    • Of course! When you transplant them to larger pots, you can use a mix specifically for cacti and succulents, or make your own by using a well-draining potting soil, some coarse, builder-grade sand, and some perlite (3 parts/2 parts/1 part). You could use Turface or poultry grit instead of sand, and you could use pumice or crushed granite instead of perlite.

      You’re doing great! Everyone is a beginner at some point. Good luck!

  6. Hello, I am wondering how shallow, or deep, a pot needs to be for the 2-2&1/2 inch succulents to live in? I just bought a great rectangular shaped one, but it seems too shallow as it is less than 2 inches deep. I’m trying to find out more information so I can buy another planter or use this one. Thank you

    • Hi, Terri!

      Succulents do best in a pot that is approximately 10% wider than the width and 10% deeper than the height of the plant. In this case, a pot that is around 2-3/4″ in depth and width (unless you’re planting multiple succulents together) would be best.

  7. Hi! Thank for this very informative article. I have a question. I just started this succulent addiction and I’m wondering if I put a grow light on for long period of time, will that make succulents grow faster? I also live in Michigan and I know very well I can’t put them outside.

    • Hi, Ella!

      Using a grow light will help your succulents continue growing at a faster rate than they would with the limited sunlight we have during the winter here. I suggest having the light on for 10-14 hours a day and make sure to check the information that comes with the light to find the distance that the light should hang over the succulents. If they start looking a bit stretched, then move the light a little closer, just make sure that the light isn’t too warm so it doesn’t burn the plants.

      Good luck!

  8. Hi Lisa,

    Recently acquired a quite large cluster of saucer plants tangled together and almost overgrowing. Have you have much experience and/or success pruning succulents? Turned a large portion into smaller trimmings to be planted elsewhere. But, was curious how often generally pruning and shaping is done.

    Great article. Take care.
