Cacti (Cactaceae) are considered to be the house plants par excellence and can be found in almost every apartment. No wonder, after all, the exotic guests have all sorts of advantages to offer. Especially its robust nature and the fact that the plant can cope with a bit of neglect over a long period of time make it a popular, easy care houseplantthat is just as appreciated by beginners as it is by gardening professionals. But their appearance also makes the cacti so popular, because their spherical and prickly growth has meanwhile achieved cult status. Every now and then, however, you should do something good for the robust houseplants - for example by repotting them. In this video we reveal how this works and what you have to pay attention to.

With their frugal nature and their high robustness, cacti are ideal plants for anyone who does not have a pronounced green thumb. Every now and then, however, the easy-care houseplants also need attention and should be repotted - this is the only way to keep them beautiful for years.

When and how often do you have to repot cacti?

In fact, cacti (depending on the species) only need to be repotted every two to five years. The perfect time for this is from late January to March, when the new growing season for the cacti begins. But even after flowering into September, the cacti can be repotted without any problems.

The plant clearly shows whether it is time for a new pot: If it becomes too big for its old pot and grows Going beyond the brink or looking for new paths through the holes in the pot with your roots, it's time for a change of scenery. The soil also provides information about whether the cactus needs to be repotted again - if it is compacted or depleted, you should think about a new container. You should also buy freshly bought cacti in their new home a new pot. There are several reasons for this: On the one hand, it is difficult to estimate how old the earth is with which the cactus was acquired. On the other hand, one repeatedly encounters inferior substrate or pests that can damage the cactus in the long term. In order to give the new houseplant the best possible start in its life, it is therefore advisable to repot it after buying it.

This is how you repot cacti

Repotting cacti can be a prickly business if you don't know how to do it. But in order for the prickly houseplants to thrive even after years, such a change of scenery is inevitable - we will tell you the best way to go about it.

That’s what you need

It doesn't take much to replant cacti - in fact, most items can be found in every household. You need:

• cactus
• Bigger pot
• Inner pot with holes
• Planting clay
• Cactus soil
• shovel
• gloves

The right soil for cacti

Although cacti are considered particularly robust, they are rather petty when it comes to choosing their soil. In fact, they can rarely be cultivated well in normal potting soil - this rarely meets the requirements of the exotic houseplants and thanks to its high concentration of nutrients it ensures a stout growth. You should pay special attention to the structure of the earth: only well-ventilated and crumbly Substrates allow the cactus to develop its roots and provide enough nutrients and water to record. At the same time, however, the soil must also be structurally stable and offer the plant enough support so that it does not tip over. In addition, the earth should be able to absorb and store water, even if it was completely dried out. Finally, the buffering capacity and the pH value are also important for the optimal growth of the cacti - most species prefer a slightly acidic soil.

In order to meet all of these requirements, it is worthwhile to use special cactus soil from specialist retailers. These are mostly geared particularly well to the needs of the houseplants and also have a particularly good concentration of nutrients, which almost all of them Cactus species is well received. One can You can also mix the cactus soil yourself. This offers the great advantage that the substrate can be precisely adapted to the needs of a certain species and thus individually tailored to the individual cacti.

The perfect vessel for cacti

Clay or plastic pot? In the case of cacti, this question can unfortunately not only be decided by personal taste, because the different pot materials can have a major impact on the cultivation of the plant. Plastic pots have the great advantage that water is distributed particularly evenly in them Excess moisture can escape through the drainage holes in the floor, so that there is no waterlogging comes. Clay, on the other hand, is breathable, but also absorbs water and allows it to evaporate through its pores. This phenomenon can be of advantage for particularly moisture-sensitive species, but it also means that cacti in the clay pot have to be watered significantly more often. If you also use a planter, you should make sure that no excess water collects - otherwise there is a risk of root rot.

But not only the material, but also the size and shape of the pot are important for cacti: columnar If possible, cacti should be given a heavy, sturdy pot to prevent them from tipping over. As a rule of thumb, one can assume that the diameter of the pot should be around a third of the height of the plant. Spherical cacti do not need such a firm stand, but should be at least a finger width There is a gap between the plant and the edge of the pot to leave enough space for the plant to grow. Shallow-rooted species such as the agaves (agave) are better off in a planting bowl, as the earth dries faster here - cacti with beet roots - like the Schnapskopf (Lophophora williamsii) - on the other hand, need a particularly narrow and deep pot.

Procedure for repotting cacti

Even if cacti usually don't get a lot of attention, it's important to give them a little time every few years and repot them in a larger container. Before you start work, however, you should pay attention to suitable protective clothing: Protection against thorn-proof gloves made of leather or rubber the hands in front of the pointed spines and prevent painful stings, which can easily catch fire when working with the cactus soil can. For cactus species with particularly long or pointed thorns, it is also recommended to use a Pliers or a grip made of paper or styrofoam work to reduce the risk of injury minimize.

Now you can prepare the new pot: Ideally, you work with an inner pot with drainage holes, because this prevents waterlogging. This drainage effect is supported by planting clay, with which you fill a little less than a quarter of the pot. In addition to its structural effect, the plant clay has the additional advantage that it binds water particularly well and can release it back into the surrounding soil if necessary. Now you can fill the inner pot with some cactus soil.

Now you should begin to carefully detach the cactus from its old pot and remove the soil. Particular sensitivity is required here, as none of the fine roots of the cactus should be damaged if possible. The soil loosens particularly well if you don't water the cactus about a week before repotting - the dried out soil loosens much more easily from the fine root tissue. Then you can put the cactus in its new pot. You should not press the plant with force, but put it on a few times - this promotes a good connection between the cacti and the new substrate without compacting the soil too much. Once the plant is in place, the substrate is loosely filled around the plant. Make sure that the cactus is just as deep in the ground as in its old pot. Otherwise, cacti in particular will begin to rot at the root neck. Finally, you only have to carefully press the earth around the cactus before it can be returned to its original place.

Summary - repotting cacti:

• 1. Put on thorn-proof gloves
• 2. Fill the inner pot a little less than a quarter with planting clay
• 3. Fill the cactus soil in the inner pot
• 4. Carefully remove the cactus from the old pot
• 5. Carefully remove old soil from the root ball
• 6. Put the cactus in the new pot and press it gently
• 7. Fill the pot with cactus soil
• 8. Gently press the earth

Care for the cactus after repotting

Repotting is a lot of stress even for a tough plant like the cactus. For this reason, it is especially important to give it proper care after transplanting. However, unlike many other plants, you shouldn't treat cacti with a large amount of water after repotting - in fact, it is ideal not to water at all for about a week after repotting to allow the plant to get used to its new home can. In addition, you should avoid locations with direct sunlight (especially with scorching midday sun) for the first three to four weeks. Only when good new roots have taken place are the plants able to deal with extreme heat and solar radiation again.

The perfect location for cacti

Originally, cacti mostly come from particularly dry regions with high levels of solar radiation in America. Your demands on a location in the apartment are accordingly: Bright rooms with lots of light are ideal for the prickly exotic species. The cacti do not mind dry heating air either - however, the indoor plants cannot tolerate high humidity, such as that found in the bathroom. On the other hand, the fact that cacti like it particularly hot is just a widespread misconception. In fact, many get by with mild temperatures and some Species of cacti are even so hardythat they are not only suitable as a houseplant, but also for free-range husbandry.
