Caring for Cacti
When it comes to repotting cacti are plants that can sometimes be hard to judge. By their nature the roots of cacti tend to be quite small in proportion to the size of the plant. A cactus should only be repotted into a larger pot when it has completely filled its old pot with roots, no more than about once every three years. When repotting it usually a good idea to invest in compost specially mixed for growing cacti, as this will be well drained and have the right nutrient levels to keep your plants healthy. One of the main problems faced by cacti growers is the fact that they are notoriously hard to repot because of their spines. This handling problem can be over come however by either winding a collar of rolled up newspaper around the plant and using this as an improvised handle or by using fire side tongs to help maneuver the plant. To repot simply lift the plant out of its pot using your makeshift handle, break away any loose soil around the top and sides of the root ball that might have become caked and stagnant.
