Things That You Need for Repotting a Cactus Plant
We’ll tell you how to repot a cactus without getting hurt, but you need to prepare some tools for this process including pot, soil, pebbles, leather gloves, tissue paper sheets, and tape. Below, we’ll tell you how to find the right pot and soil for repotting a cactus.
The Right Pot for Repotting Cactus
If you want to know how to repot a cactus, you need to know how to find a suitable pot as well. Cactuses can grow in almost any container, but we suggest terracotta pots. The porous surface of these pots allows moisture to escape, preventing rot and mold and keeping the soil dry. You can find these pots in any hardware or gardening store.
For terracotta pots or any other, you need to make sure that the container has a good drainage system. Cacti prefer dry soil and their roots will rot if the dirt is too damp. In addition to root rot, damp soil can result in fungus growing in the pot alongside your cactus too.
If you’ve found a nontraditional pot that you really like, but it doesn’t have a drainage hole, make your own drainage system with pebbles. Before filling the container with cactus soil, use larger rocks at the bottom of the container, and then smaller pebbles.
Before following the steps of how to repot a cactus, you also need to determine the perfect size for the container. It is tempting to buy a large pot to give your plant plenty of space to grow, but the right container for repotting a cactus is only a little bit larger than the previous container. Don’t forget that cactus species enjoy a small and cozy pot.
The Right Cactus Soil
The perfect cactus soil is a nutrient-rich soil with moisture control and drainage. There are many brands that offer cactus compost specially designed for desert plants like cacti. All of them are good options as cactus soil and for repotting cactus. While helping your plant to grow well, the fast-draining formula of cactus compost also prevents root rot.
Cactus compost imitates the desert soil for your cactus, so it can grow under the best living conditions. Cactus soil usually consists of sand or grit, soil, and peat moss.

We don’t know what kind of cactus you have, but for most species, we recommend repotting the plant when its roots show through the container drainage holes. Or, when the cactus crown reaches the edge of the container. You will see this occur every 2 to 4 years. Even if your cactus hasn’t outgrown the pot after four years, we recommend repotting it to freshen up the soil.
Repot your cactus during the dry season, usually in late winter or early spring. Roots may break during the process, and moisture can cause those broken roots to rot.

How to Repot a Cactus: Removing
When wrapping your cactus is done, place some pebbles over the pot’s drainage hole. This way, water can run out without moving the cactus soil. Next, put 1 or 2 inches of cactus soil into the container and gently press it down.
Put on the gloves. Gently but firmly, grasp the base cactus (above the root ball) and pull to remove the plant. Tilting the pot and tapping on it can help loosen the soil a bit.
When the cactus is out of the pot, shake some of the cactus compost away. Old cactus soil has not many nutrients left and you need to replace it.

There should be an inch between the cactus soil surface and the pot lip.
