Your Guide to Repotting Indoor Plants
As the days get longer, we experience a welcome increase in sunlight. This signals our plants to wake up and start growing. Now is a great time to think about re-potting indoor plants!
Plants will let you know when it is time to repot
- The soil is delpleted of nutrients; plants will look pale in color.
- The plant is root bound; there are more roots than soil in the pot.
- The height of the plant in greater than 3x the height of the pot its planted in. Exceptions would be floor plants and certain design aesthetics.
- Roots are pushing out the bottom of the pot or encircling the stem.
- Plant growth has slowed or ceased, and it is not due to winter dormancy.
- The soil has lost water holding capacity requiring more frequent watering; water runs right out the drainage hole each time you water.
- The plant is top heavy or is unstable.
How to choose a container
When repotting plants for the purpose of increasing the root zone, we recommend bumping your plant up one size. Grower pots are generally sized in even numbered inches: 4", 6", 8", 10 etc.
Always choose a pot with drainage. Grower or Nursery pots as they are often referred to are great place to start. These can be easily inserted or "dropped into" decorative containers that do not contain drainage. Simply take you plant to the sink to water, let it drain, then return it to its decorative container.
If you like to plant directly into decorative container, that's just fine. Terra cotta pots almost always have a drain hole and corresponding saucer. Also, when you purchase a pot at Tonkadale we are happy to drill a hole for you - just ask at check-out!

How to choose a potting soil.
Potting soil is the foundation of plant success. A proper potting mix ensures that your plant has everything it needs including micro and macro nutrients, aeration (oxygen), and water retention. All-purpose potting soil will work great for most repotting projects but do take a minute to consider a specialty soil if you are growing orchids, African violets, bonsai plants, cactus, succulents. We reccommend Espoma's All Purpose Potting Soil for basic planting needs and we love Sol Soils' Cactus Gritty Mix for our succulent and cactus friends!
If you want to dig deeper into potting soil, there is always the opportunity to mix your own. We have several custom soil mix recipes on the blog for fine tuning your media including an arid mix, aroid/epiphyte mix, terrestrial mix, maranta mix, and a carnivorous mix.
Check out step by step instructions to create an aroid mix in this video!
Time to Repot
When it's time to repot, it's nice to have a plan in place. Use a long and low Rubbermaid (or other) bin to catch the mess. Don't be afraid to get in there and get a little rough, plants can handle it!
- Gently pull the plant out of the old pot. You can loosen the pot from the plant by squeezing or pressing on the pot.
- Break up the root ball to "wake up" the roots.
- Add a few inches of soil to new pot.
- Place your plant in the new pot.
- Back fill in soil around the plant.
- Lightly tamp down soil
- Water in well - until the soil drains out the bottom of the pot.
- Nice work!
Repotting Videos for Visual Learners!
We have several repotting videos available on our YouTube page. The two selected below are particularily good because they show more advanced repotting projects. In the Repotting a Monstera video, we highlight how to use a moss pole, and in the Fiddle Leaf Fig video, you will learn how to transplant a larger specimen. Take a look!
