Which plants? • Cacti What Cacti only need repotting every three to four years. Only move into a larger pot if the roots have reached the sides. If you are repotting into a more attractive pot, choose one roughly the same size. 1 Choose a pot just slightly larger, with drainage holes in the base. Use John Innes No.2, or general potting compost, with added grit. Wear gloves.
Squeeze the pot to loosen the roots. Wrap folded newspaper or thin card in a loop around the body of the cactus to lift it from its pot. 4 Add a layer of grit around the surface of the compost. This helps stop the base of the cactus from rotting, and looks attractive. 3 Place it into its new pot. Fill around it with more of the compost mixed with grit, firm gently to remove air holes. The top of the rootball should still be at the surface of the compost.
