Although a cactus prefers slightly cramped growing conditions in a container, it may outgrow its pot and need a larger one. When its roots reach the edge of the container, you must repot the cactus. Then, with attention to detail and following the recommendations, you can give your large cactus fresh soil in a larger container to help it continue to thrive.
Instructions
Choose a container that is only 1 to 2 inches (2.5 to 5 cm) larger than the current container to ensure you don't place the cactus in a too-large pot. A cactus in a too-large container may begin to decay because the soil stays too wet. Fill the container approximately halfway with a cactus potting mix.
Wear leather gloves and long sleeves to protect your hands and arms from the cactus. Loosen the cactus from the container by inserting the trowel gently around the perimeter of the container. Wrap the cactus with newspaper so you can grasp it and gently work it loose from the container.
Transfer the cactus from the old container to the new container. Set the cactus in the container so that the plant is at the same depth as it was in the old container. Fill in additional soil around the roots and gently firm the soil to complete the repotting.
Place the repotted cactus in its regular growing location, where it will receive direct sunlight. Do not water it for two to three days after repotting.
Tips and Warnings
Repot your cactus in the spring before it begins growing actively again.
Install a stake in the new container when you repot if your large cactus requires support. Choose a stake as tall as the cactus and place it in the container at the same time you put the cactus in. Fill soil around the cactus roots and the stake, then tie the stake to the cactus with stretchy plant ties.
