It’s possible to propagate Calathea Warscewiczii but they’re not as easy to propagate as other plants as you can’t simply take a cutting. Instead the way to propagate this plant is through root division.
(If you find this useful then take a look at our Super Quick Care Guide For Calathea Warscewiczii.)
Wait until new shoots of your Calathea have started to come out of the soil where you can clearly see their separation from the original plant. Then take the plant out of it’s pot careful to work the roots out rather than just pulling the plant by the stem. You can use your fingers to gently knead away the soil. Once the roots are exposed and the plant is out of the pot gently work at separating the root systems while being careful not to break any of the larger roots. You may snap a few small roots and this is fine, just try and keep the damage to a minimum.
Repot the original pot back into it’s old pot with enough extra soil to fill in for the missing part of the plant. Then take your new section of Calathea Warscewiczii and plant it in a smaller pot. Make sure you water the soil thoroughly and place the plant in dappled light. Remember that your new plant will need humidity just like your old plant so be sure to mist it or provide it with enough humidity.
Important note! Not all cuttings or roots divisions will work and you may lose your plant. With this in mind it’s always better until you have enough growth to take several sections and that way you have a greater chance of success. If you rely on one new section of plant then you have a greater chance of losing your new cutting.
