Propagation is the most common in seed form, as it is a natural process by which the cactus flowers seeds and roots. However, among growers at home, propagating by stem cuttings is probably the most popular decision.

You can propagate your cactus successfully from the plants that you already have. You simply remove the cactus at a crook or individual segment point. You take off the growth piece and gently place it into the soil.

Once the segment roots itself, you’re going to start watching new growths form from the segment.

You don’t have to cover it up with soil, but just make sure that the base of the cutting is connected to the ground. With adequate watering and care, you should start to see new routing within the first few weeks.

They just simply serve as a straw source to suck up the nutrients and water into the trunk itself where it is stored. The water is then evenly distributed throughout the growth nodes to distribute the nutrients.

Root systems can look very different depending on the cactus species you’re looking at. Some root systems may be fleshy and thick, while others are shallow, thin, and corklike. All roots have absorbent hairs on the outside that shed much like our body cells, regenerating with new and healthy growth.
