Calathea plants generally do not like to be overcrowded, as this can lead to issues with root health and overall plant growth. It is best to provide enough space for the roots to grow and expand without becoming restricted. Therefore, it is recommended to keep one calathea plant per pot.
When it comes to repotting calathea, it is important to do so every few years to prevent the roots from becoming overcrowded. This is typically done by transferring the plant to a slightly larger pot, with a diameter that is 1 to 2 inches larger than the current pot. Repotting allows the plant to have more room for root growth and can help promote healthier and more vigorous growth.
During the repotting process, it is also a good opportunity to refresh the potting mix. Calathea plants prefer well-draining soil that retains some moisture but does not become waterlogged. A mix of peat moss, perlite, and/or vermiculite can provide a suitable growing medium for calathea.
To repot a calathea, start by carefully removing the plant from its current pot. Gently loosen the root ball to separate any tangled or circling roots. It is important to handle the roots with care to avoid damaging them. Inspect the roots for any signs of rot or disease and trim off any damaged or dead roots.
Place a layer of fresh potting mix at the bottom of the new pot, then position the calathea in the center. Add more potting mix around the sides, ensuring that the plant is at the same depth as it was in the previous pot. Gently press down the soil to secure the plant in place.
After repotting, thoroughly water the calathea to help settle the soil and hydrate the roots. It is also a good practice to mist the leaves regularly to provide some humidity, as calathea plants appreciate higher humidity levels.
Calathea plants do not like to be crowded, and it is best to keep one plant per pot to allow for healthy root growth. Repotting every few years in a slightly larger pot can help prevent overcrowding and promote optimal growth for your calathea. Remember to use a well-draining potting mix and provide adequate moisture and humidity for these beautiful plants.
