Overpotten

Overpotten, known in English as repotting into a larger pot, is a horticultural practice in which a plant is moved to a container with more volume to accommodate root growth and to refresh the soil. The aim is to improve root development, nutrient availability, and drainage. It is commonly performed when a plant becomes root-bound, the potting mix has degraded, or growth slows despite adequate light and water.

Indications include roots visible at drainage holes, a dense, circling root ball, soil that dries quickly after watering, or a plant that dries out between waterings despite regular care. The timing is usually during the active growing season in spring or early summer; repotting during dormancy or extreme heat should be avoided. Use a pot only moderately larger than the current one to prevent waterlogging.

Choosing a pot and soil: select a pot with drainage holes and a size that is proportionally larger than the old pot. Use fresh potting mix suited to the plant type: tropical houseplants prefer a looser mix with organic matter, while cacti and succulents require well-draining soil. Ensure proper drainage and use a saucer if needed.

Procedure: water the plant before removing it from its pot. Gently lift and loosen the root ball, prune away dead roots, and tease apart dense sections if possible. Place a layer of fresh soil in the new pot, set the plant at the same depth as before, fill around the roots, and firm the soil. Water to settle the mix.

Risks: using a pot that is too large can lead to persistent moisture and root rot. Not all plants benefit from frequent repotting; many finish to fresh soil every 1–3 years depending on species.
