How Often Should You Change the Soil in Houseplants?

By | Updated April 22, 2023

If you’re like most people, you probably don’t think about how often you should change the soil in your houseplants.

Well, it’s time to start thinking about it!

Soil plays a vital role in the health of your plants, and if it isn’t changed often enough, your plants will not thrive.

This article will discuss how often you should change the soil in houseplants and why it is so important.

We will also provide some tips for how to do it effectively!

Why Plants Need New Soil

Plants need new soil because they need the minerals and nutrients in the soil to grow and thrive.

The soil in your plant’s potting container will eventually break down and become depleted of the nutrients that your plant needs to thrive.

With time, the soil structure will also break down, making it more difficult for your plant to take up water and nutrients.

There are a few signs that your plant is telling you it needs new soil, such as:

  • The plant is not growing as quickly as it used to
  • The leaves are yellowing or falling off
  • The plant is wilting
  • The plant is not flowering

If you see any of these signs, it’s time to give your indoor plant a fresh start with some new potting soil.

Healthy soil is essential for healthy houseplants.

When you change the soil in your plant’s potting container, you provide your plant with the new minerals, nutrients, and structure it needs to grow and thrive.

How Often Should You Change the Soil in Houseplants

You should change the soil in houseplants every one to two years.

The frequency with which you change the soil will depend on how often you water your indoor plants, how much light they get, and what type of plant it is.

Cacti and succulents, for example, need less frequent watering than ferns or impatiens.

If you water your plants weekly, they’ll need less frequent soil changes than if you water them daily.

The soil in houseplants also breaks down over time, so it’s essential to replenish it with fresh soil every so often.

When this happens, you’ll notice that the soil doesn’t hold water as well and that your plants may start to wilt more easily. 

Also, if you’ve ever watered your plant and the water seems to run straight through the potting mix without being absorbed, it’s time to change the soil.

Changing the soil in your houseplants is a simple way to keep them healthy and happy. 

By doing it every one to two years, you’ll ensure that they have the nutrients they need to thrive.

How To Know When To Change Plant Soil

The health of your houseplants depends on many factors, including the type of soil you use.

While there is no definitive answer for how often to change plant soil, there are some telltale signs that it might be time for a fresh batch.

Here are a few things to look out for:

Your Plants Seem Unhealthy

When you start to notice that your indoor plants are wilting, yellowing or otherwise looking unhealthy, it might be time to change their soil.

Over time, soil can become compacted and lose nutrients, making it difficult for roots to absorb water and causing the plant above ground to suffer.

If you think your plant’s soil might be the problem, try changing it and see if there is an improvement.

The Soil Is Compacted or Looks Dry and Crumbly

If you notice that the soil in your pot is looking dry and crumbly or is very dense and compacted, it’s probably time for a change.

Both of these conditions can make it difficult for roots to grow and absorb nutrients, so freshening up the soil will give your plant a chance to thrive.

The Water Isn’t Draining Properly

If you find that water is pooling on the soil’s surface or not draining away quickly, it could be a sign that the potting soil is too dense.

This can cause problems for plant roots, as they can rot if they sit in wet conditions for too long.

If you notice this problem, try changing to a lighter soil mix that will drain more easily.

The Water Is Draining Away Too Quickly

On the other hand, if you find that your plant’s soil is drying out too quickly, it might be because the mix is too light.

This can cause the plant to suffer from drought stress, as the roots will not be able to get enough moisture from the soil.

If you think this might be the case, try using a soil mix that is more dense and will hold water better.

There Is an Abundance of Roots Crowding the Pot

Roots need space to grow, so if you notice them crowding the pot or growing out of the drainage holes, it’s time to transplant your plant into a larger container with fresh soil.

This will allow the roots to spread out and absorb the nutrients they need.

It Has Been a Few Years Since You Last Changed the Soil

Even if your plant seems to be doing well, it’s a good idea to change the soil every few years.

This will ensure that it stays nutrient-rich and doesn’t become compacted over time.

Plus, it’s an excellent opportunity to give your plant a fresh start in a new pot.

Your Plant Is Rootbound

If you notice that your plant is becoming pot-bound, meaning the roots are growing in a tight circle around the edge of the pot, it’s time to repot and change the soil.

This can cause the plant to become stunted and prevent it from absorbing nutrients properly.

Repotting houseplants into fresh soil will give the roots room to grow and allow the potted plant to thrive.

There is no hard and fast rule when it comes to changing plant soil.

However, if you notice any of the above signs, it’s a good indication that it might be time for a fresh batch.

If you’re not sure how often to change plant soil, a good rule of thumb is to do it every one to two years.

This will ensure that your potted plants have the fresh, nutrient-rich soil they need to thrive.

When Is the Best Time To Change Plant Soil?

The best time to change plant soil is in the spring, when plants are just starting to grow.

Your plant will be actively growing and will be able to take advantage of the fresh, nutrient-rich soil.

This will give your plant a chance to adjust to its new environment and get a head start on the growing season.

With fresh soil, your plant will develop a strong root system that will support it throughout the year.

If you wait until later in the season, your plant may suffer from transplant shock as it tries to adjust to the new conditions.

However, if you can’t change the soil in the spring, don’t worry.

You can still do it later in the season, but be sure to give your plant plenty of time to adjust before the winter sets in.

Do You Need To Use a New Pot or Just Change the Soil?

If you’re not sure whether you need to change the pot or just the soil, there are two things to consider.

Take a Look at the Pot Itself

If it’s cracked, chipped, or otherwise damaged, it’s probably time for a new one.

On the other hand, if the plant pot is in good condition, but the soil is looking tired, you can probably get away with just changing the soil.

Consider the Size of the Pot

If your plant has outgrown its current home, you’ll need to transplant it into a larger pot.

However, if the pot is the right size but the soil needs refreshing, you can change the soil without needing to upgrade to a new pot.

When in doubt, it’s always best to err on the side of caution and go for a fresh pot and soil.

This will give your plant the best chance to thrive.

How To Change the Soil in Houseplants

Now that you know how often to change the soil in houseplants, it’s time to learn how to do it.

The process is quite simple and only takes a few minutes.

You can change the soil in your houseplants by following these simple steps:

1. Remove the Plant From Its Current Pot

To do this, simply turn the pot upside down and tap it gently until the plant slides out.

If the roots are tightly bound, you may need to use a sharp knife to loosen them before removing the plant.

Once the plant is out of its pot, shake off any excess soil clinging to the roots.

Make sure to remove as much of the old potting soil as possible so that the roots can easily absorb the nutrients from the new soil.

2. Prepare the Pot Where the Plant Will Go

If you’re changing the pot and the old soil, make sure to clean it before adding fresh potting soil.

You can do this by scrubbing it with warm, soapy water or using a diluted bleach solution.

Rinse the pot thoroughly and allow it to dry completely before adding new soil.

If you’re only changing the soil, rinse out the old pot and allow it to dry before adding fresh soil.

Adding new soil to a dirty pot can lead to root rot, so it’s important to ensure the pot is clean before proceeding.

3. Choose the Right Type of Soil

When choosing the right soil for your indoor plant, there are a few things to keep in mind.

First, make sure to choose a potting mix appropriate for the type of plant you’re growing.

For example, cactus and succulents need a well-draining mix, whereas most other plants prefer a more moisture-retentive mix.

Once you’ve chosen the right potting mix, it’s time to add it to the pot.

4. Add Fresh Soil to the Pot

Fill the pot about two-thirds of the way full with fresh soil, and then gently place your plant in the center.

Backfill the pot with more soil, being sure to leave enough room at the top for watering.

Make sure the roots are covered with soil, but the plant’s crown is not.

Once the pot is filled with soil, give it a good pat down to settle everything in place.

5. Water the Plant

After you’ve changed the soil in your houseplant, it’s important to water it thoroughly.

This will help the roots settle into their new home and absorb nutrients from the fresh soil.

When watering, be sure to use room-temperature water and avoid getting the leaves wet.

Water the plant until the soil is moist but not soggy, and then allow it to drain fully before putting it back in its spot.

6. Monitor the Plant

After you’ve changed the soil and watered your plant, it’s important to monitor it closely for the next week or so.

Make sure to keep an eye on the leaves and stems for any signs of stress, such as wilting or yellowing.

If you notice any problems, be sure to address them right away.

With a bit of care and attention, your plant will soon adjust to its new soil and be back to looking its best.

Final Thoughts

How often should you change the soil in houseplants? The answer may vary depending on the type of plant, but a good rule of thumb is to change the soil every one to two years.

Doing this will ensure that your indoor plants are getting the nutrients they need and that they are not being overwatered or underwatered.

If you notice that your plant is struggling, don’t wait to change the old soil – it could be just the thing your plant needs to thrive!

A healthy houseplant is a happy houseplant, so make sure to give your plants the love and care they deserve.
