Repotting Houseplants: Signs It’s Time and How to Do It

An indoor environment featuring a variety of houseplants with lush green leaves in different stages of repotting. One plant is in its original pot, roots growing out of the drainage holes, indicating it's time for a bigger pot. Another plant is out of its pot, exposing the compacted root ball. The third plant is being repotted: it's set in a new, larger pot, with fresh soil being added. Potting tools such as a trowel, gloves, and bag of soil are neatly arranged nearby. There are no people or text present.

Understanding the Basics of Houseplant Care

Before diving into the process of repotting, it’s essential to grasp the basic care requirements for houseplants. Each species has unique needs, but there are general parameters you can follow to ensure their health and growth.

  • Pet Friendly: Many houseplants are safe for pets, but some can be toxic. Always ensure the plants you choose are non-toxic to cats and dogs if you have furry friends around.
  • Light Requirements: Light is crucial for photosynthesis. Plants like the snake plant tolerate low light, but others such as the fiddle leaf fig thrive in bright, indirect sunlight.
  • Watering: Overwatering is a common cause of plant death. It’s vital to water according to the plant’s needs and ensure proper drainage to prevent root rot.
  • Humidity: Tropical plants usually require higher humidity levels. You can increase humidity by misting the leaves, placing a tray of water near the plants, or using a humidifier.
  • Temperature: Most houseplants prefer temperatures between 65°F and 75°F (18°C – 24°C). Avoid placing your plants near drafty windows or heating vents.
  • Difficulty: Some plants are more forgiving and perfect for beginners, like the spider plant, while others, such as the orchid, require more attention and finesse.

Signs Your Houseplant Needs Repotting

If you’re wondering whether your green companion is ready for a new home, look out for these telltale signs:

  • Roots are Growing Through Drainage Holes: This is a clear indicator that the plant has outgrown its current pot.
  • Roots are Circling the Soil: If upon checking you find the roots are tightly wound in a circle, it’s time to give your plant more space.
  • Plant is Top-Heavy and Falls Over: A disproportionate pot size can cause the plant to tip over because of the weight of the foliage.
  • Water Runs Straight Through the Pot: This suggests there isn’t enough soil to hold water for the roots to absorb.
  • Slow Growth or No Growth: A lack of space can limit a plant’s growth. Repotting may give it the necessary room to expand.
  • Visible Salt and Mineral Buildup: White, crusty buildup on the soil surface or outside of the pot suggests it might be time to change your potting mix.

The Right Time to Repot

Timing is everything when it comes to repotting. The best time to repot most plants is during their active growing period, commonly in the spring or early summer. This allows the plants to recover and root more efficiently in their new pots.

Choosing the Right Pot

Selecting a suitable pot is crucial for the wellbeing of your plant. A pot that’s too large can lead to water logging, whereas one that’s too small can restrict growth. Typically, you should aim for a pot that is about one to two inches wider in diameter than the current one.

Best Potting Mix for Your Plants

The right potting mix can make a significant difference to your plant’s health. A well-draining, nutrient-rich mix is ideal. For example, Miracle-Gro Indoor Potting Mix is favored for its ability to support a range of houseplants, providing the right balance of airiness and moisture retention. Reviewers often mention that it promotes robust root development and plant growth.


  • Contains no compost or bark, which are known to shelter gnats
  • Feeds plants for up to 6 months
  • Designed for a wide variety of indoor plants


  • Some users reported a need to water more frequently due to the mix’s excellent drainage

Step-by-Step Guide to Repotting Your Houseplant

Now that you know when and why to repot your plants, let’s walk through the steps to ensure you do it successfully:

  1. Gather Your Supplies: You’ll need the new pot, fresh potting mix, a trowel or spoon for scooping, and scissors or pruning shears.
  2. Remove the Plant Gently: Ease the plant out of its pot by holding the base and tipping the pot. If the plant doesn’t come out easily, tap the pot’s sides or run a knife around the edge. Remember to be gentle to avoid damaging the roots.
  3. Prune the Roots (if necessary): If the roots are extremely coiled or there are any dead roots, lightly prune them to encourage new growth.
  4. Add Fresh Potting Mix: Fill the new pot with a base layer of fresh potting mix. Ensure it’s enough so that the plant sits at the same depth it was before.
  5. Reposition Your Plant: Set your plant in the center of the new pot and fill around with more potting mix. Tap the pot gently to settle the soil without compacting it too much.
  6. Water Thoroughly: Water your plant generously to help settle the soil and hydrate the roots. Let the excess water drain away completely.

Post-Repotting Care

After repotting, place your plants in a location where they can adapt comfortably to their new environment. Avoid direct sunlight for a few days and keep an eye on the soil moisture. It’s normal for plants to take some time to adjust, so minimal watering and patience are key during this period.

When to Fertilize After Repotting

Resist the temptation to fertilize immediately after repotting, as the fresh soil often contains enough nutrients. Wait for four to six weeks before introducing any fertilizer, then proceed based on the plant’s specific needs. Opt for quality fertilizers like Osmocote Smart-Release Plant Food, which is widely recommended for its controlled release of nutrients, ensuring that plants get what they need over time.


  • Nutrients are released slowly over six months
  • Suitable for indoor and outdoor plants
  • Easy to apply


  • The granules can be too prominent for very small pots

Caring for Your Repotted Houseplants

Once you’ve successfully repotted your houseplant, you should understand the steps to maintain its health. This involves recognizing signs that your plant is adapting well to its new container and knowing how to care for it going forward.

  • Monitor Plant Health: Watch for new growth and sustained vibrancy in the leaves as positive signs. Any wilting, yellowing, or dropping leaves could indicate that the plant is under stress and may require attention.
  • Regular Watering: New soil can dry out more quickly. Make sure to check the soil moisture regularly. Water the plant when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot.
  • Adequate Sunlight: Ensure your plant is getting the right amount of light according to its specific needs. Move it to a brighter spot or provide shade as necessary.
  • Maintain Humidity: If your houseplant thrives in high humidity, you might want to continue using a pebble tray or humidifier to maintain these conditions, especially in dry climates or during winter months.
  • Be Patient: It’s normal for plants to take a few weeks to settle into their new pots. They may not show immediate growth as they are putting energy into establishing their roots in the new soil.

Preventing Common Repotting Mistakes

Repotting your plants offers many benefits, but it can also introduce risks if not done correctly. Here are some common repotting mistakes and how to avoid them:

  • Using the Wrong Size Pot: A pot that’s too large can lead to overwatering issues. Conversely, a pot that’s too small can constrict a plant’s root system. Aim for a pot that is 1 to 2 inches larger in diameter than the current one.
  • Choosing the Wrong Soil: Not all potting mixes are created equal. Make sure to select a mix suitable for your specific type of plant. A cactus mix, for instance, is best for succulents and cacti because it offers superior drainage and aeration.
  • Over or Under Watering: Check the moisture level of the soil before watering. And always ensure that there are drainage holes at the bottom of the pot to prevent water from pooling.
  • Ignoring the Plant’s Stress Signals: After repotting, keep an eye out for signs of stress like discoloration or drooping leaves. The quicker you can address these issues, the better chance your plant will recover.
  • Tampering Too Much: Some plants take a while to adjust. Unless you see signs of distress, it’s best to give your plant some space to adapt.
  • Forgetting to Clean the Tools: Always clean your repotting tools before you begin. This helps prevent the spread of diseases from one plant to another.

FAQs on Repotting Houseplants

Likely, you have questions about repotting your houseplants. Here’s some expert advice on common concerns:

  • How often should I repot my plants?: Most plants need to be repotted every 12 to 18 months. But this can vary depending on the plant’s growth rate and the container size.
  • Can I repot a plant during the winter?: It’s best to repot in the spring or early summer when plants are in their active growth phase. However, if a plant is extremely root-bound or showing signs of distress, it should be repotted regardless of the season.
  • Should I water my plants right after repotting?: Yes, watering right after repotting helps to settle the soil and ensure that the roots are making contact with the new potting mix.
  • What if the leaves start turning yellow?: Yellowing leaves could be a sign of stress from the repotting process but also from too much water, not enough light, or a nutrient deficiency. Assess all care aspects to determine the cause.
  • How can I tell if I’ve packed the soil too tightly?: The soil should be firm enough to support the plant but not so compact that water doesn’t drain properly or the roots can’t grow freely.

Choosing Decorative Pots and Accessories

While the functionality of a pot is your primary concern, aesthetic value also plays a role, especially for plants in living areas. You might want to choose a decorative pot that compliments your home décor. Ceramic pots come in various colors and patterns and are popular for their classic look.

When selecting a decorative pot, it’s essential to consider if it has drainage holes. If not, you may opt to use it as a cache pot—placing a smaller, functional pot inside. Be wary, though, as double potting can make it difficult to check the moisture level of the interior pot’s soil. You’ll need to remove the inner pot during watering to allow the water to drain away.

Additionally, consider accessories like potting mats, which make the repotting process cleaner and more manageable. These are usually made from waterproof materials and can be easily wiped down and stored away. Similarly, soil scoops are handy for neatly transferring potting mix into your new pot.

Understanding Root Health and Pruning

The roots of your plants are just as important as the part you see above the soil. When repotting, it’s a chance to examine the root health and make necessary adjustments. Look for firm, white roots – these are signs of a healthy plant. If you encounter any black, mushy, or excessively dry roots, these should be pruned away to encourage new growth and prevent disease.

When you prune roots, use a pair of sharp, clean scissors or pruning shears. Trim off any dead or rotting roots, but avoid over-pruning as this can stress the plant. After pruning, ensure your plant is repositioned in its new pot with ample room for the roots to spread out.

Understanding the Benefits of Repotting

Repotting isn’t just about managing an overgrown plant. It’s also a way to refresh the soil and boost your plant’s health. Over time, soil can become compacted and depleted of nutrients. Additionally, repotting gives you the chance to check the overall health of your plant and address any issues you might not see above the soil, like root problems.

By providing fresh soil and a roomy environment, you’re giving your plant the best chance for continued growth and vitality. This care leads to more robust plants that can better resist pests and diseases.

One product that comes highly recommended for repotting is the Fiskars Micro-Tip Pruning Snips. These small, sharp shears are perfect for precise root pruning and snipping away dead foliage. Users praise the snips for their comfort, precision, and the fact that they stand up well to repeated use.
