How to Repot a Cactus Plant (An Easy Step-by-Step Guide)

By

Do you have a cactus that’s starting to look a little too big for its pot? Or maybe the soil is starting to dry out, and your cactus is looking a bit sad.

It’s time to repot your cactus!

Repotting a cactus is an easy process that can be done in just a few simple steps.

In this article, we will walk you through the process of how to repot a cactus safely and effectively.

How To Know When to Repot a Cactus?

Most cactus plants will only need to be repotted every two to five years.

However, there are a few things you can look for to help determine when your cactus needs a new pot.

If you see any of the following, it’s time to repot your cactus:

The Pot Is Too Small

When a cactus plant is root-bound, the roots have nowhere to grow and begin to crowd the bottom of the pot.

If you see roots coming out of the drainage holes or winding their way around the outside of the pot, it’s time for a larger pot.

The Soil Is Drying Out Quickly

When a cactus is pot-bound, the soil will become dry very quickly. This is because the roots take up all the moisture in the pot.

If you find yourself watering your cactus more than once a week, it’s probably time to repot.

The Plant Is Tilting or Leaning

A healthy cactus should be standing tall and proud in its pot.

If your cactus is leaning to one side or the other, it indicates that the pot is too small and the roots are crowded.

The Plant Is Outgrowing Its Pot

As your cactus grows, it will eventually become too large for its pot.

You’ll need to repot your cactus into a larger pot when this happens.

You can also divide your cactus into multiple smaller plants and pot each one separately.

The Pot Is Starting to Crack or Break.

If your pot starts to crack or break, it’s time for a new one.

The same goes for pots that are chipped or have any other kind of damage.

The Cactus Is Top-heavy and Might Fall Over

A cactus that is top-heavy is at risk of falling over.

If your cactus has a large, heavy top and a small, lightweight bottom, it’s time to repot into a heavier pot.

The Cactus Is Wilting or Looking Overall Unhealthy

If your cactus is wilting, has yellow or brown leaves, or is otherwise looking unhealthy, it might be a sign that it’s not getting enough light, water, or nutrients.

Before you repot your cactus, make sure to check its lighting, watering, and fertilizing requirements.

But if you’re unsure of what’s causing the problem, repotting your cactus into fresh soil might be just what it needs to get back to good health.

When Is the Best Time to Repot a Cactus?

The best time to repot a cactus is during the growing season, typically in the spring or summer.

This is because the plant will be actively growing and will be able to recover from the repotting process more quickly.

However, you can repot your cactus at any time of year as long as it’s not during its dormant period.

During the dormant period, the cactus is not growing and will not be able to recover from the repotting process.

How Often Should You Repot a Cactus?

Growing cactus plants can be a fun and rewarding hobby.

But like all plants, they need the right amount of care to stay healthy.

One important part of caring for a cactus is knowing when and how to repot it.

So, how often should you repot a cactus? Generally, you should repot your cactus every two to three years.

However, you may need to do it more or less frequently, depending on the size and type of cactus plant you have.

Repotting succulents and cacti is a great way to give them a fresh start and encourage new growth.

If your plant is looking etiolated (leggy), has stopped growing, or is starting to look cramped in its pot, it’s probably time for a repot.

On the other hand, if your cactus is small and isn’t showing any of these signs, you can probably wait a few more years before repotting.

In general, it’s better to err on the side of repotting too often rather than not enough. That way, your plant will always have fresh soil and room to grow.

How to Repot a Cactus Plant Step-by-Step

It’s easy to forget about your cactus plant until you notice it’s looking a little wilted.

Don’t be discouraged when you see that your beloved plant needs a new pot!

Repotting a cactus is easy and only takes a few simple steps.

Follow these easy steps to repot your cactus successfully:

Step One: Gather Supplies

Before you get started, make sure you have all the supplies you need.

You’ll need a new pot (one size larger than the current pot), a potting soil mix, a small shovel, and a knife or scissors.

As cactus spines can be pretty sharp, it’s also a good idea to have some gardening gloves and newspaper or a towel to protect your hands and surfaces.

Step Two: Prepare the New Pot

If you’re using a new pot, start by giving it a good wash with soap and water.

Make sure the new pot has drainage holes in the bottom, so your plant doesn’t become waterlogged.

Rinse it well, and then let it dry completely. Once the pot is dry, add an inch or two of the potting soil mix to the bottom.

Cacti need a soil that drains well, so don’t use regular potting soil or garden soil.

The best type of potting mix to use is a cactus soil mix, or you can make your own by mixing one part potting soil, one part coarse sand, and one part perlite.

Step Three: Remove the Cactus from the Current Pot

Carefully remove the cactus from its current pot. Remove any old soil that’s clinging to the roots, and then use a small shovel to help loosen any large clumps of soil.

If the potting mix is really stuck to the roots, you can use a knife or scissors to cut it away.

Be careful not to damage the cactus’ roots in the process.

If the plant is rootbound (meaning the roots are growing in a tight circle), gently loosen them with your fingers before removing the plant.

Once the plant is out of the pot, check for any damaged or rotting roots and trim them away with a sharp knife or scissors.

The remaining roots should be white or light-colored.

The plant will be more susceptible to root rot if the damaged roots are not removed.

Step Four: Put the Cactus in the New Pot

Once you’ve trimmed the roots, place the cactus in the new pot.

Make sure it’s sitting at the same depth as it was in the old pot and that the plant is centered in the pot.

If it’s not, the plant may lean to one side or topple over when it gets too big.

Fill in around the roots with more of the potting mix, using your fingers to pack it in place lightly.

Don’t pack it too tightly, though, as this can damage the roots.

Cacti don’t need a lot of water, so only add enough potting mix to cover the roots.

Step Five: Place the New Pot in a Bright Location

After you’ve repotted the cactus, find a sunny location for it to live.

Cacti need at least six hours of sunlight each day, so a south- or west-facing window is ideal.

However, if you live in a hot climate, your cactus may prefer some shade during the hottest parts of the day.

Step Six: Don’t Water for a Week

Once you’ve repotted your cactus, resist the urge to water it right away.

It’s best to wait a week before watering so the roots can adjust to their new home and start growing.

After a week, start watering your cactus only when the soil is dry to the touch.

Cacti are susceptible to root rot, so it’s important not to overwater them.

Water your cactus less in the winter months as they typically go dormant during this time and don’t need as much water.

How to Care For Newly Repotted Cactus

Now that you know how to repot a cactus, it’s essential to understand how to care for it in the weeks and months following.

As your cactus adjusts to its new container and grows, it will be more susceptible to root rot and other problems.

Here are a few tips for caring for newly repotted cactus:

  • Do not water the cactus for at least one week after repotting it.
  • Once you do start watering it again, be very careful not to overdo it; give the cactus only a small amount of water at a time and wait until the soil is dry before watering again.
  • Make sure the pot has good drainage so that the cactus can’t sit in water and rot its roots.
  • Place the cactus in a sunny spot where it gets at least six hours of direct sunlight per day.
  • Keep an eye on the cactus for any signs of problems (e.g., wilting, shriveling, discoloration) and address them as soon as possible.

By following these tips, you can help your cactus make a smooth transition to its new pot and thrive for many years to come.

Final Thoughts

Growing cactus plants can be very rewarding, but they require some special care.

One of the most important things you can do for your cactus is to repot it every one to two years or whenever it becomes rootbound.

Repotting a cactus is not difficult, but it’s important to do it carefully not to damage the plant.

By following the steps outlined in this article, you can repot your cactus with ease and help it thrive for years to come.
