Cactus growing too tall for its pot. Afraid it will tip over.

Question

My cactus is fairly skinny, but appears to be healthy. It is now over 2 feet tall in a 6 inch pot. I am always afraid the roots will pull out and it will tip.

Answer 1

The cactus has outgrown its pot and needs to be repotted into a larger container with good drainage. In addition to a more stable base, the increased soil volume will provide better water and nutrient holding capacity. Use a cactus/succulent potting soil. And you may need to support the plant with a stake to prevent toppling.
