Introduction: why repotting is essential
Repotting is one of the most important actions for the health of your indoor plants. Yet, it is also one of the most feared by beginners! Rest assured: with the right advice and a little practice, repotting becomes a simple gesture that will transform your plants.
In this comprehensive guide, you will discover when to repot, how to do it step by step, and especially how to choose the right pot and the right substrate for each type of plant.
5 signs that a plant needs to be repotted
How to know if your plant needs a new pot? Here are the warning signs:
- Roots come out through the drainage holes — The clearest sign that it lacks space
- Growth slows down or stops — Even with good care, it stagnates
- Water no longer drains properly — The substrate is too compact or the roots occupy all the space
- The plant dries out very quickly — The roots have absorbed all the available water
- The pot deforms or cracks — The root pressure is too strong
💡 Good to know: some plants (like Sansevieria or Pothos) like to be cramped and can stay several years in the same pot.
When to repot your indoor plants?
The best period: spring
The ideal time to repot is in spring (March to May), when plants come out of their winter dormancy and enter an active growth phase. They then recover much more easily from repotting stress.
You can also repot at the beginning of summer (June), but absolutely avoid autumn and winter, except in emergencies (rot, pot breakage, etc.).
Repotting frequency according to the plant's age
- Young plants (1-3 years): every year
- Adult plants: every 2-3 years
- Large plants or slow growth: every 3-5 years, or simple surface renewal (replacement of the top layer of soil)
How to repot a plant: step-by-step guide
Necessary materials
- A new pot (2-3 cm larger in diameter than the old one)
- Soil suitable for your plant
- Clay balls or gravel for drainage
- A knife or spatula
- Gloves (optional, but recommended for irritating plants)
- A watering can
The steps of repotting
1. Prepare the new pot
Place a layer of clay balls at the bottom (2-3 cm) to ensure good drainage, then add a first layer of fresh soil.
2. Gently remove the plant from its pot
Turn the pot over while holding the base of the plant, tap the bottom and sides to loosen the root ball. If the roots are very compact, feel free to gently untangle them with your fingers.
3. Inspect the roots
Take the opportunity to check the condition of the roots. Cut those that are dead (brown, soft) or damaged with a clean tool.
4. Set the plant in its new pot
Center the root ball and add soil all around, pressing down lightly. The collar (base of the stem) should remain at the same level as before.
5. Water generously
A good watering after repotting helps the soil settle and the roots to establish well. Let the excess drain.
6. Place the plant in the shade for a few days
Avoid direct sunlight for 3-5 days to limit post-repotting stress.
Choosing the right pot: size, material, and drainage
Pot size
Golden rule: increase by 2 to 3 cm maximum in diameter. A pot that is too large retains too much moisture and promotes root rot.
The material
- Terracotta: breathable, ideal for plants sensitive to excess water (succulents, cacti)
- Glazed ceramic: aesthetic, retains moisture better
- Plastic: lightweight, economical, perfect for hanging pots
- Decorative pot: decorative, but be careful to empty stagnant water

Drainage: essential!
Make sure the pot has at least one drainage hole. Without it, water stagnates and roots rot. If you use a decorative pot without a hole, place the plant in an inner pot with drainage.
Which potting soil to choose for repotting?
Not all plants have the same needs:
- Tropical plants (Monstera, Pothos, Philodendron): universal potting soil + perlite or bark for aeration
- Succulents and cacti: special cactus soil, very draining
- Orchids: bark-based substrate, never regular potting soil
- Ferns and shade plants: soil rich in organic matter, which retains moisture
💡 Tip: always add 20-30% perlite or vermiculite to your potting soil to improve drainage and aeration.
Repotting calendar by popular species
| Plants | Frequency | Best period | Particularities |
|---|---|---|---|
| Monstera | Every 2 years | March-April | Likes a slightly tight pot |
| Pothos | Every 2-3 years | April-May | Very tolerant, easy to repot |
| Ficus | Every 3-4 years | March-April | Avoid disturbing the roots |
| Sansevieria | Every 3-5 years | Spring | Prefers to be cramped |
| Calathea | Every 2 years | April-May | Rich and moist soil |
| Succulents | Every 2-3 years | March-April | Highly draining soil mandatory |
After repotting: the right actions
Post-repotting watering
Water generously right after repotting, then wait for the soil to dry before the next watering. The roots need time to settle and absorb water efficiently.
Managing post-repotting stress
It is normal for your plant to show signs of stress for 1-2 weeks:
- Leaves slightly falling
- Slowed growth
- Slightly tired appearance
To help it recover:
- Place it in shade or partial shade for a few days
- Avoid fertilizer for 4-6 weeks (the new soil already contains nutrients)
- Maintain stable ambient humidity
- Do not move the plant for 2 weeks

Mistakes to absolutely avoid
- Repotting in winter — The plant is resting and recovers poorly
- Choosing a pot that is way too big — Risk of root rot
- Forgetting drainage — Stagnant water = rotten roots
- Pressing the soil too hard — Roots need air
- Overwatering after repotting — Allow the soil time to dry between waterings
- Repotting a sick plant — Treat the problem first (pests, rot) before repotting

FAQ: your questions about repotting
Can you repot a flowering plant?
It is better to avoid it, as repotting can cause flowers to drop. Wait until the end of flowering, unless it is an absolute emergency.
Should you water before or after repotting?
Water after repotting to help the soil settle and the roots establish well. Before repotting, the soil can be slightly moist to facilitate removing the plant from its pot.
What to do if the roots are very tangled?
Gently untangle them with your fingers or a clean tool. If they form a very compact knot, you can make a few vertical cuts (1-2 cm) to stimulate the growth of new roots.
Can you repot into a pot of the same size?
Yes, if you want to limit the plant's growth. In this case, slightly trim the roots (10-15%) and replace all the soil.
How long after purchase should you repot?
If the plant seems healthy and the roots are not coming out of the pot, wait at least 2-3 weeks for it to acclimate to its new environment. If it is clearly cramped, you can repot sooner.
Conclusion: repotting, an essential act of care
Repotting is not a chore; it is a true act of care that allows your plants to thrive and grow healthily. By respecting the right timing (spring!), choosing the right pot and soil, and following the steps in this guide, you offer your plants the best conditions to prosper.
And don't forget: every plant is unique. Observe it, listen to its needs, and adjust your actions accordingly. With a little practice, repotting will become a moment of connection with your plants!
