Myths about cactus care: facts and fictions


Cacti are popular houseplants due to their unusual shapes and the little care they require. However, many people mistakenly think that cacti are extremely undemanding and require almost no care. In this article, we will explore some of the myths and facts about caring for cacti to help you keep your cacti healthy and happy. We will look at issues such as watering, soil, and fertilizing cacti, and give you practical tips on how to take care of your cacti in the best possible way.

Myth: Cacti rarely need water

Cacti are known for not needing a lot of water. However, this is only partially true and can lead to a myth that makes them difficult to maintain. It's important to understand that cacti have different needs and that there's no one-size-fits-all rule about how often they should be watered. Some species of cacti actually rarely need water, while others need regular watering. Some factors that can affect watering needs include the size of the pot in which the cactus grows, the type of soil, and humidity. To find out whether your cactus needs water or not, you should check the bottom in the pot. When it's dry, it's time to water. If it is still wet, you can postpone watering for a few more days. It's also important to note that, as a general rule, cacti are better watered thoroughly rather than watering superficially. This means that you should water the cactus thoroughly so that the water reaches the bottom of the pot. By following these tips and taking into account your cactus's individual needs, you can give it the right amount of water and ensure it stays healthy.

Myth: Cacti can live in any pot

Myth: Cacti can live in any pot. This is a common myth that often leads to cacti being planted in unsuitable pots. However, the truth is that cacti have special requirements for their pot. A pot that is too large can cause the roots to rot, as excess water cannot drain properly. It is important to choose a pot with adequate drainage to avoid waterlogging. A good tip is to choose a pot with a diameter that is only slightly larger than that of the cactus. This way, the plant will have enough space for its root system, but the excess water will still be able to drain away. It is also important to choose a pot made of a porous material such as clay or ceramic, as this will help absorb excess moisture and protect the roots from rot. Keep in mind that the right pot for your cactus is vital to provide it with optimal growing conditions and maintain its health.

Myth: Cacti need a lot of sunlight

Myth: Cacti need a lot of sunlight

It is a common myth that cacti need a lot of sunlight. In fact, cacti are plants that can live in different environments, including shaded areas. However, it is important to note that the amount of sunlight that a species of cactus requires can vary from species to species.

Some types of cacti thrive best in full sun and can actually be harmed if they don't get enough sunlight. However, other species prefer a shadier location and may burn in direct sunlight.

It's important to understand what kind of cactus you have and what kind of environment it needs. If you are unsure, you can always do your research or ask an expert for advice.

Another important factor is the duration of sun exposure. Some species of cacti can survive in direct sunlight for long periods of time, while others only need a short time. Some species also require a certain amount of shade to be protected from the hot midday sun.

In conclusion, the myth that all cacti need a lot of sunlight is false. Each species has different requirements for light and shadow. It is important to understand the needs of your own cactus and provide it with a suitable environment.

Myth: Cacti don't need fertilizers

Myth: Cacti don't need fertilizers

There is a common myth that cacti do not need fertilizers. But that's actually not entirely true. Although cacti are hardy plants and are able to survive in extreme environments, they still need nutrients to grow and thrive optimally.

Cacti have special requirements for their nutrient supply. It is important to choose a fertilizer that is specifically designed for cacti. These fertilizers contain the right mixtures of nutrients that cacti need, such as nitrogen, phosphorus, and potassium.

The addition of fertilizers helps the cacti to strengthen their resistance to diseases and pests. It also promotes the growth and development of healthy roots. A well-fertilized cactus will have stronger stems and better flower formation.

However, it is important to follow the correct dosage. Over-fertilization can cause burns to the roots and damage the cactus. It is recommended to strictly follow the instructions on the packaging of the fertilizer and adjust the dosage accordingly.

In conclusion, the myth that cacti do not need fertilizers is not correct. The addition of special cactus fertilizer in appropriate doses is important to promote the growth and health of the plants. By taking care of the needs of our cacti, we can ensure that they provide pleasure for a long time.

Fact: How to water cacti correctly

Fact: Proper watering of cacti is crucial for their growth and survival. Although it's a common myth that cacti rarely need water, it's important to note that they need to be watered regularly, but in moderation. Excessive watering can lead to root rot, while too little water will cause the plant to dry out.

To properly water cacti, one should use the "dry and water" method. This means that you let the cactus dry out completely before watering it again. This may vary depending on the environment and time of year. In general, cacti should be watered about once a week in spring and summer, while they need to be watered less often in the fall and winter.

It's also important to use the right kind of water. tap water with a high lime content can harm the cacti, so it is better to use either rainwater or stale tap water.

When watering, you should make sure that the water can drain well. Excess water in the pot can cause waterlogging and damage the roots. Therefore, use pots with drainage holes and make sure that excess water can drain away.

Proper watering is crucial for the well-being of the cacti. By following these simple steps, you can ensure that your plants get enough moisture without causing them any harm.

Fact: The Importance of the Right Soil Mix for Cacti

Fact: The Importance of Proper Soil Mixing for Cacti

The right soil mix plays a crucial role in the healthy growth and development of cacti. Unlike other plants, cacti require a special substrate that meets their specific needs. A good soil mix should be both permeable and water-resistant to allow the cacti to grow their roots optimally.

When choosing the right soil mix, it is important to pay attention to a balanced combination of ingredients. A suitable mixture usually consists of mineral material such as sand or gravel to ensure good drainage. This prevents waterlogging and prevents root rot. At the same time, organic components such as compost or peat should be added to provide nutrients and improve the soil's water-holding capacity.

It is also advisable to keep an eye on the pH of the soil. Cacti usually prefer a slightly acidic to neutral pH. A pH between 6 and 7 is ideal to ensure that plants can absorb nutrients efficiently.

It is important to note that different types of cacti may have different soil mixing requirements. For example, some species prefer a sandier soil, while others require a greater amount of organic matter. Therefore, it is advisable to find out about the specific requirements of each type of cactus before repotting or replanting.

By using the right soil mix, cacti can thrive optimally and stay healthy. Good drainage, adequate nutrient supply and adjusted pH are crucial for the well-being of these fascinating plants. With a little attention and care when choosing the substrate, you can ensure that the cacti will give pleasure for a long time.

Fact: How to properly fertilize cacti


To properly fertilize cacti, it is important to follow a few steps. First of all, it should be known that cacti generally do not need much fertilizer because they are able to extract nutrients from their soil. However, if you notice that the plant is not growing properly or is losing its color, it may be necessary to fertilize it. In this case, you should use a special cactus fertilizer, which is available in any garden center. It is advisable to apply the fertilizer only during the growing season, that is, from spring to summer. The best time to apply is at the end of winter or early spring when the plants begin to grow. To apply the fertilizer correctly, you should dilute it with water and then pour it on the soil around the plant. It is important not to water directly on the plant or spray on the leaves, as this can cause burns. You should also be careful not to overapply the fertilizer, as this could damage the plant. To sum up, fertilizing cacti is all about choosing the right time and fertilizer and applying it with caution and care.

Now that we've dealt with some myths and facts about caring for cacti, we can now better understand how to properly treat these plants. We've learned that not only do cacti rarely need water, but they also need a special soil mix to thrive. We also learned that cacti can live in any pot as long as it is well drained. It is also important that cacti get enough sunlight and need to be fertilized occasionally. So, proper care of cacti can be a bit complicated, but it's definitely worth it.

However, it is important to emphasize that every cactus is different and has different needs. There are many different types of cacti and each has its own requirements for water, light and soil. So, when buying a new cactus, you should always research the specific requirements. This is the only way to ensure that your cactus stays healthy and lives a long time.

Overall, cacti are fascinating plants that require special care. However, with the right knowledge and tools, you can ensure that your cacti are happy and healthy. So, why not buy a new cactus and test your green thumb skills?
