How to Repot Houseplants: A Step-by-Step Guide for Plant Parents

Any plant enthusiast should know how to repot their houseplants. Plants often outgrow their containers and start requiring more space and fresh soil to thrive. We’ll walk you through how to rehome your plants, from recognizing when it’s time to make the change to expertly caring for plants in their new space.

When to Repot Your Houseplants

We recommend repotting your plants in late winter or early spring as they enter a robust growth phase. Determine which plants need repotting on a case-by-case basis—many tropical plants prefer to be slightly root-bound and won’t benefit from frequent repotting. Others need to be relocated once a year or more.

Signs Your Plant Needs Repotting

Plants have ways to communicate their needs. Look for these indicators:

• Stunted growth or pale, straggly appearance: A plant might be unable to flourish in its current container due to malnourishment from soil degradation.
• Water runs straight through the pot without being absorbed: Soil loses its ability to retain moisture as it becomes more compacted or root-bound.
• Top-heavy plants that frequently topple over: Plants become unstable when the upper portion outpaces root growth.
• Roots poking out of drainage holes or soil surface: Protruding roots indicate that your plant is far too cramped and that you should repot it as soon as possible.
• Tightly coiled roots visible when gently removed from the pot: Bound roots don’t absorb nutrients as effectively.
• Pots lacking proper drainage holes: Poor drainage invites numerous issues, such as root rot and pest infestations.

Supplies Needed for Repotting

Preparation is key to successful repotting. Before you get your hands dirty, make sure you have all the right tools and materials.

Use high quality potting mix.

Essential Tools and Materials

Gather the following:

• Trowel: An essential tool for scooping soil and managing plant roots.
• Gardening gloves: To maintain hygiene and prevent irritation.
• Sharp, clean scissors or pruning shears: For precise cuts on roots and foliage.
• Clean, sharp knife: Useful for making gentle incisions to untangle girdled roots.
• High-quality potting mix tailored to plant type: Each plant species has unique soil requirements based on water and nutrient needs.
• New pots with drainage holes: Select pots 1-2 inches larger in diameter than the current one to allow room for growth.
• Newspaper or plastic sheeting: These help protect work surfaces from potential messes.

Step-by-Step Guide to Repotting Houseplants

Take a strategic and caring approach when repotting your houseplants. Follow these steps to minimize plant stress and encourage growth.

Step 1: Water the Plant

Lightly water the plant a day before repotting. Moistening the soil helps with easing out the root ball and softens compacted areas, reducing shock to the plant. 

Step 2: Remove the Plant from Its Current Pot

Position the pot on its side, and, with one hand supporting the main stem, delicately withdraw the pot with the other hand. If you encounter resistance, gently tap the pot’s sides to loosen the soil. Use a knife for added leverage if necessary, but avoid tugging on the stem.

Step 3: Inspect and Prune the Roots

Once you have the plant free, examine the root system. If everything looks good, continue to the next step. Otherwise, sheer off any bound roots to promote lateral development. Trim out dead or excessively large roots to invigorate the plant.

Step 4: Clean the New Pot

If you’re reusing a pot, sanitize it with hot, soapy water to get rid of any lurking pathogens or invasive pests. Make sure it’s dry before you put in the new plant.

Step 5: Add Fresh Soil

Add a gentle mound of fresh potting mix into the new pot. Use this base to support the new plant and make sure the upper root ball sits at least half an inch below the pot’s rim. This gives you adequate watering space.

Step 6: Position the Plant

Center the plant in its new pot, making sure it stands upright. Check from different angles to make sure it’s stable and looks nice.

Step 7: Fill in with Soil

Add additional layers of potting mix, gently pushing downward to eliminate air gaps. Avoid burying the plant deeper than it was in its previous pot—this can obstruct natural growth.

Step 8: Water Thoroughly

Generously water the newly established plant until you start to see water flow out the drainage holes. This helps with soil settlement and root growth in the new pot.

Step 9: Final Adjustments

Take a look at the plant after watering. If the soil is uneven or the plant is leaning, add more soil in the needed spots.

Step 10: Prune and Clean

Trim away unhealthy foliage and wipe the plant to eliminate dust or lingering soil. This step helps your plant photosynthesize better as it’s adjusting to the new pot.

Caring for Newly Repotted Plants

The post-repotting adaptation phase is crucial for making sure your plant continues to thrive. Follow these care recommendations:

• Water management: Water the plant as usual, but avoid overwatering to minimize the risk of root rot.
• Fertilization caution: Wait three to four weeks before fertilizing to give your plant time to adjust to its new environment.
• Lighting conditions: Avoid direct sun exposure immediately after planting. Too much sun can exacerbate the plant’s stress response from the repotting.
• Stress monitoring: Watch for signs of stress—such as color changes, wilting, or leaf curling—and adjust your care schedule as needed.

Common Mistakes to Avoid When Repotting

Even seasoned plant parents can make mistakes during repotting. Try to avoid these common pitfalls:

• Using a pot that’s too big, which increases the risk of overwatering.
• Choosing decorative pots that don’t have drainage.
• Over-compacting the soil, restricting natural root expansion.
• Repotting at the wrong time and causing undue shock.
• Using garden soil that invites pests and disease.

Repotting Specific Types of Houseplants

Certain plants have specific repotting needs. Here’s a short guide for some common houseplants:

• Succulents and Cacti: Use porous cactus mix in a terra cotta container for the best results conditions.
• Orchids: Repot orchids every other year. Use a special orchid blend soil and a pot with extensive drainage.
• Ficus Trees: Repot in the spring, moving the tree to a pot that’s only slightly larger than its current one.
• African Violets: Choose shallow pots filled with special violet mix. Only repot once the plant becomes root-bound.
