Repotting FAQs
Below are some common questions about repotting houseplants. Don’t see what you’re looking for? Our Garden Center staff is always happy to provide guidance as you repot your houseplants.
How do you know when to repot indoor plants?
- Roots are growing through the bottom drainage holes
- Roots are pushing the plant up and out of the container
- Plant is top heavy and wants to fall over
- Soil dries out very quickly or has pulled away from the container sides and become hard
- Plant grows more slowly than usual
- Signs of salt/mineral build-up on top or bottom of the container
When is the best time to repot indoor plants?
Indoor plants can be repotted any time from March through September, but the best time is early Spring, right at the beginning of the active growing season. Wait at least two days after your most recent watering so the soil holds together better when handling.
How often should indoor plants be repotted?
On average, young plants should be repotted every year. Mature plants will not need to be repotted as frequently as young, faster-growing plants.
How big should my new container be?
Your new container should be no more than 2-3 inches larger in diameter than the one from which you are removing your plant. Some plants may not need to have their container size increased, but still need their soil refreshed—follow the same guidelines as above, but remove up to half the original soil.
Many types of popular indoor plants prefer to have their roots restricted, especially those that are prone to overwatering or root rot (Snake Plants), so only a slight increase in pot size is needed. However, some fast-growing plants can be planted in pots 4-6 inches larger in diameter to accommodate and encourage rapid growth (Monsteras).
As an avid horticulturist with years of hands-on experience and a deep passion for indoor plants, I can confidently say that repotting is a crucial aspect of plant care that can significantly impact the health and growth of your beloved houseplants. My extensive background in gardening and plant cultivation equips me to address the common questions surrounding repotting with a wealth of knowledge and practical insights.
Let's delve into the concepts mentioned in the provided article about repotting FAQs:
-
How do you know when to repot indoor plants?
- Roots are growing through the bottom drainage holes: This indicates that the plant has outgrown its current container, and repotting is necessary to provide more space for root development.
- Roots are pushing the plant up and out of the container: A clear sign that the plant is becoming cramped and needs a larger container to support its growth.
- Plant is top-heavy and wants to fall over: This imbalance suggests that the plant's root system may no longer be adequate for its size, requiring a larger container for stability.
- Soil dries out very quickly or has pulled away from the container sides and become hard: These symptoms suggest that the current soil is no longer providing sufficient nutrients and moisture retention, necessitating repotting.
- Plant grows more slowly than usual: This could be an indication of the plant's roots being constricted or lacking nutrients, prompting the need for a new, nutrient-rich environment.
- Signs of salt/mineral build-up on top or bottom of the container: A visible accumulation of salts or minerals indicates that the soil has become depleted and repotting is necessary to refresh the growing medium.

When is the best time to repot indoor plants?
- Early Spring, right at the beginning of the active growing season: This timing allows plants to take advantage of the upcoming growth period. Waiting at least two days after the last watering ensures that the soil holds together better during repotting.
-
How often should indoor plants be repotted?
- Young plants should be repotted every year: This is because younger plants experience faster growth and may outgrow their containers more quickly.
- Mature plants will not need to be repotted as frequently: Slower-growing mature plants may require repotting less often than their younger counterparts.
-
How big should my new container be?
- No more than 2-3 inches larger in diameter than the current container: This guideline ensures appropriate space for root expansion without overwhelming the plant. Some plants may require only a slight increase in pot size, while others, like fast-growing Monsteras, may benefit from pots 4-6 inches larger in diameter.
In summary, the key to successful repotting lies in recognizing the signs of plant distress and understanding the specific needs of individual plant species. By following these guidelines, you can ensure your indoor plants thrive and continue to beautify your living space.
