Cactus care 101: How to grow and maintain desert plants

Cactus is a fascinating plant belonging to the family Cactaceae, which boasts over 2,000 unique species. It is originally from the America, particularly in arid and desert regions, where it has adapted to life in some of the most inhospitable areas on Earth. This makes it exceptional because, compared to other plants, it can survive with very little water and under a lot of sunshine.

The most important feature of Cactus is their succulence. Unlike usual plants, Cactus has fat, fleshy stems that store water, while others do not. This enables these plants to reserve water for long periods, enabling them to last through lengthy dry spells. These stems are often ribbed or segmented, allowing the Cactus to expand or contract according to how much water they have absorbed.

Cactus has evolved ways of reducing water loss. Most species either lack leaves or possess very small leaflets. In place of true leaves, however, it possesses spines that serve multiple functions, such as protecting them against herbivores and providing shade by limiting airflow across the plant’s surface, thus reducing transpiration losses.

Besides being a hardy vegetation type, Cactus produces bright, beautiful flowers. Although blooms may only appear for short periods, they are often striking and brightly colored. Some Cactus species also produce fruits that are important to desert ecosystems since various animals can use them as food.

Cactus plants make great additions to any garden or home, as they always remind people about desert landscapes and everything else associated with such scenery. Tools and supplies are essential for growing and caring for these plants. Growcycle offers a range of products, from specialized cactus soil to pots, to help ensure that these desert plants thrive in any environment.

Essential Care Tips to Thrive Cactus

Here are some basic care tips to help keep a Cactus healthy and thriving. Following these simple steps will make it easier to ensure the cactus stays strong and vibrant.

• Light

Cactus is a sun-loving plant in the desert. They do not thrive in low-light conditions and require plenty of natural light to grow strong and healthy. To maximize daylight exposure for indoor Cactus, place them towards south—or west-facing windows where they can receive sunlight for much of the day.

If such a window is absent, an eastward one will adequately meet the needs of the Cactus. Such a location allows for some low-light direct morning sunshine, which is less intense but not worthless. Breathing areas with little or no lighting should be avoided, as this would weaken, elongate, or whiten Cactus due to a lack of enough sunlight.

Most Cactus species need at least six hours of direct, bright sunlight daily. Ensuring that enough sunlight is available will keep the plant in good health and maintain its attractive appearance.

• Watering 

Cactus plants are known for tolerating drought, so they do not require frequent watering. The right amount of water without over-watering will make this plant thrive; hence, ‘soak and dry’ is a must-follow rule for Cactus cultivation. Before watering, they should be allowed to dry out completely before thoroughly soaking the soil. As a result, moisture does not accumulate in this plant, avoiding root rot that might arise due to its overabundance.

During summer and spring growing, one may have to water it often. For instance, if it’s contained in a small pot, like 3 inches in diameter or less, frequent watering may be necessary, such as once per week, since small pots are usually quick to dry up. But if the pot contains a large cactus plant, then watering every 2 or 3 weeks would be enough. As the seasons change and the Cactus enters its dormant phase in the winter, reducing watering significantly is important, as it needs far less water during this period.

A moisture meter can be a helpful tool for avoiding overwatering. This device allows gardeners to check the soil's moisture level and ensures they water their cactus only when the soil is truly dry.

• Humidity 

Cactus is a desert plant that can grow with low humidity. Therefore, it is crucial to ensure that the air around Cactus is dry to keep them in a good state of health. Too high humidity can result in problems such as fungal growth or soaked soil that may lead to root rot.

Thus, it would be more appropriate to avoid placing Cactus in areas like the bathroom and kitchen, as these rooms are typically more humid than others. These spaces usually trap moisture inside, creating an unfavorable environment for cactus plants. Instead, choose rooms with proper airflow and low humidity to resemble a desert condition where Cactus thrives well. Keeping this plant dry will help avoid common issues and promote its healthy growth.

• Temperature 

Warm conditions are perfect for growing Cactus plants, with optimal temperatures being between 60 and 80 degrees Fahrenheit (16-27°C). These factors are similar to those of the desert habitats in which they grow naturally, thereby necessitating indoor provision of such warmth to the plants.

This plant can withstand low temperatures during winter but should not be exposed to cold drafts or sudden temperature changes. A sudden drop in temperature could shock the plant and may lead to damage. For example, putting a Cactus next to a drafty window or an air conditioner vent during colder months would expose it to cold air, which is not good.

Consistent temperature keeps this plant healthy. If the house's temperatures fluctuate, it will be important to maintain a consistent environment for the cactus by shielding it from any sources of cold wind or heat spikes.

• Soil 

Cactus require specific soil conditions to thrive, one of the most important factors being well draining soil. These plants are vulnerable to root decay when they hold too much moisture; thus, employing the right soil is vital. A basic Cactus potting mix that releases water fast and has less moisture content tends to be the best option for planting Cactus.

Unlike regular potting soil or garden soil, the Cactus mix contains fewer nutrients and does not retain water around roots. The typical potting soils usually have higher moisture retention capabilities and more nutrients than this plant requires, leading to too much watering and root rot problems.

When selecting a medium, it is important to choose one specifically meant for Cactus plants rather than just succulents. This will help the Cactus grow healthy without soggy roots promoting mold growth.

• Fertilizer 

When fertilizing Cactus or succulents, always use a fertilizer specially made for them. Such fertilizers typically contain low nitrogen but high phosphorous and potassium, sufficient for healthy growth without overloading the plant.

Watering the Cactus before applying the fertilizer is important. This ensures that the roots do not burn; distributing manure on dry soil is dangerous. After dampening the soil, the diluted fertilizer can then be applied as directed by its label.

This plant does not require regular feeding, so applying fertilizer once in spring and again in summer is sufficient. Over-fertilizing isn’t needed, and it is even harmful because these plants from deserts aren’t heavy feeders.

Techniques To Grow Cactus Fast

Here are some effective techniques to help Cactus grow quickly. These practices will ensure the plant stays healthy and thrives.

Pruning

Cactus generally do not require pruning, as their growth is slow and precious, and they develop over many months. Pruning is only necessary to remove damaged or infected parts of the cactus. To avoid injuries and disease infections while pruning, wearing thick gloves and using sharp, sterilized cutting tools is important.

Propagation

The presence of offshoots or pups on a cactus means that it can be propagated. Though it can be challenging to propagate a Cactus, it remains rewarding as well. By eliminating these offshoots or pups, the mother plant’s resources are relieved by reducing the competition for water and nutrients.

The best time to propagate is in spring, so the new cuttings have a better chance of taking root. For this purpose, one will need a good pair of thick gloves, sterilized cutting tools, Cactus potting mix, and small pots. Using the rooting hormone may improve the success rate, but it isn’t essential.

• Growers start propagation by making clean cuts just below each pup or offshoot from the parent plant to avoid spreading infection into them.
• To prevent rotting, allow them to dry out until they harden or callus over for about one week in a bright, dry location.
• The cuttings should be planted into small pots filled with soilless potting medium specifically designed for succulents such as Cactus.
• If a rooting hormone is used, the end of each cutting should be dipped into it before being inserted into the moist but not overly wet soil.
• The soil should be misted regularly, keeping it slightly damp.
• After about six weeks, the roots should be fully developed, and the cuttings can then be moved into larger pots to allow further growth.

Repotting 

Cactus plants require repotting when the roots have outgrown the container, which is an important part of their care. Repotting can be a little difficult, but it will ensure that these plants remain healthy and develop well. On average, it should be repotted every 2 to 4 years, although this time can sometimes be extended by regular feeding during the growth season.

• Cactus plants have sharp spines, so it is advisable to wrap them with newspaper or cardboard to prevent accidental prickes.
• Terracotta pots are suitable for growing cactus plants as they enhance air circulation around the roots and help absorb excess water, reducing the risk of root rot.
• Check the root system before repotting; eliminate any dead or injured ones. Allowing the plant’s roots to dry for two or three days before moving it to its new pot helps identify and remove unhealthy roots more easily, reducing the risk of infection.
• Spring is the perfect season for replanting Cactus because they start doing new things as temperatures increase and daylight hours become longer.
• First, about one-third of a bag of Cactus potting mix is put into the new pot. Carefully position the ball of roots at the center of the pot.
• Add more soil around this root ball while pressing it gently until the Cactus is firmly held in place using soil compression.
• After transplanting, it is best to wait a few days before watering deeply into the pots containing the repotted Cactus. This waiting period allows the plant to establish itself in its new pot without interference.
• Over the next few weeks, monitor the Cactus, but once it has settled into its new home, return to the normal watering and feeding routine.

Common Types of Cactus

Cactus has a wide variety of shapes and sizes, each with unique characteristics. Here are a few notable types:

• Barrel Cactus

The Barrel Cactus, a member of the ferocactus genus, is known for its distinctive round shape. It is named so because of its thorny barrel-like stem, which is covered in hard, dense prickles. The remarkable flowers of the barrel Cactus are usually observed when they mature.

• Blue Candle Cactus

Blue Candle Cactus is an eye-catching species found in Mexico. Its bright, pale blue stems are typical for candle flames. This plant’s stems grow outwards freely, resembling a candelabrum, and therefore, it’s characterized by uniqueness and a very attractive appearance.

This cactus is popular due to its striking coloration and branchy construction. Blue Candle Cactus does well when exposed to direct, intense sunlight and requires little water, thereby sounding like most other common types of succulent plants that grow in arid regions.

• Mammillaria Cactus

Mexico’s Mammillaria Cactus is a lovely variety from the central parts of the country. Its stalks feature dark green spikes with attractive bronze orange hues. This drought tolerant type can form numerous offsets or side shoots, which can easily be separated to create new plants.

Benefits of Cactus Plants

Cactus and succulents are visually striking houseplants and offer several practical benefits that make them a great addition to any home. Here’s how having a Cactus can enhance the living space:

• Air Purification

Like the rest of the plants, Cactus convert carbon dioxide into oxygen, so they play a role in purifying indoor air. They can also remove pollutants from the air and thus contribute to its purification. To ensure that the air in the house is thoroughly clean, it is recommended that one Cactus be kept for every two individuals in the house.

• Stress and Anxiety Reduction

Cactus can reduce stress and anxiety by lowering carbon dioxide levels, which cause irritability. Due to its calming effects, people who suffer from stress can find it an essential part of their homes or offices. Its soothing effect can support relaxation and even aid in quicker patient recovery.

• Noise Reduction

Cactus plants are also valuable indoors because they help reduce noise levels. Their surface area helps to absorb sound, making them very useful when placed close to windows, doorways, or work areas. Thus, they create more peaceful, quieter environments.

• Healing Properties

Cactus also has a range of potential health benefits. It is known for its antiviral properties and can provide safety for neurons. Additionally, it is rich in antioxidants and can help manage blood sugar levels, treat prostatic enlargement, and potentially lower cholesterol levels. It also increases indoor humidity, alleviating dry skin and itching issues.

Common Issues and Solutions

Following are some common issues that can affect Cactus plant. Recognizing these problems will help in managing them effectively and ensuring the cactus remains healthy:

• Pests

Though Cactus and succulents are generally easy to care for plants, they can sometimes suffer from pest problems. The most common insects that can attack are mealybugs and root mealies. These tiny creatures can cause many problems, especially when the cactus is not in good condition.

Keep this plant in a dry spot with plenty of sun and air to prevent pest infestation. Use fast-draining soil to help avoid excess moisture, which creates a breeding ground for pests.

• Cochineal Scale Bugs

Cochineal scale bugs are particularly concerning for Cactus, especially the Opuntia genus, such as Angel Wing or Rufida Minima Cinnamon Cactus. They suck sap from leaves which may lead to weaken or kill the plant.

Cochineal scale treatment begins by spraying water on the affected areas to expose and weaken the bugs. Then, treat the Cactus with insecticidal soap or a mixture containing 2.5 milliliters of dish soap per gallon of water. In cases where the infestation persists, it may be necessary to prune off the most affected pads and dispose of them to limit the spread.

• Severe Infestations

For serious infestations, a combination of insecticides, dormant oil sprays, and insecticidal soaps may be needed. Malathion and triazide combined with Neem oil or Volck dormant oil spray are effective treatments. However, these treatments should not be applied on hot, sunny days, as the dormant oil can burn the cactus. If the weather is too hot, use a pesticide with dish soap.
