To prepare the plant, remove plastic pot and stone wool. Shorten the roots and divide into smaller plants using your fingers or sharp scissors. Plant portions into the substrate placed a few centimetres apart to help the plants grow together quickly. Ensure plants are positioned in good lighting without shading from other plants. Add liquid fertiliser - start carefully and with a dose smaller than the recommended. Increase the dose gradually according to the plants' reaction to the fertiliser. A good rule of thumb is that leaves or plants become lighter/transparent when they lack fertiliser.
