All About Cacti:
Exploring the Fascinating World of Over 2000 Cactus Species
With over 2000 unique species, cacti are fascinating and resilient plants, that have captured the imagination of plant enthusiasts worldwide. These unique succulents are known for their ability to survive in arid and desert-like conditions, making them symbols of endurance and adaptability. With their striking shapes, from tall, columnar, and hanging cactus plants to round and globular, cacti add a touch of natural beauty to any space.
- The most remarkable characteristic of cacti is their ability to store water in their thick, fleshy stems and leaves. This adaptation allows them to withstand long periods of drought, making them low-maintenance and perfect for busy plant lovers.
- Cacti have spines instead of traditional leaves, which help reduce water loss and protect them from herbivores.
- Some cacti produce stunning flowers in vibrant colors like the Easter lily cactus, while others have interesting textures and patterns on their surface.
- They can range in size from mini cactus plants, that fit in the palm of your hand as Thimble cactus, to tall cactus plants that reach several feet in height as Saguaro cactus.

Factors to Consider When Choosing a Type of Cactus for Your Home or Garden
- Consider the size of the plant. Cactus desert plants come in all different sizes, from small varieties that can fit on your desk to large ones that will take up half of your room. Choose a size that's appropriate for the space you have available. For example, if you're making a rock garden, you should place the larger plants toward the back.

Cacti need at least four to six hours of sunlight and the right amount of water for blooming. Dormancy is important for blooms because it reduces sunlight and water, allowing some cacti to thrive.
But we do not stop there! We also want to ensure that you have all the information you need to care for these wonderful plants. Below, we have covered some essential tips on how to care for these cacti, including sunlight requirements, watering guidelines, and general maintenance. With our selection and care tips, you'll be well-equipped to nurture and enjoy your cacti collection.
Cactus are Easy to Care for & Hard to Kill
Cacti are like the superheroes of the plant world when it comes to low maintenance. They're incredibly easy to care for and are known for their resilience. With their ability to store water, they can tolerate dry conditions and don't require frequent watering. Just give them some sunlight, well-draining soil, and a little love every now and then, and they'll thrive! Plus, their unique and diverse shapes make them a stylish addition to any space. Below, you will learn in detail about the tips and tricks to grow them.
How to Water Your Cactus – Seasonal Care
One of the most important aspects of cactus care is watering.Cacti are the only true drought-tolerant plants. Cacti are succulents, storing water in their leaves and stems.
As a result, they don't require watering as often as other plants. You should generally only water your cactus weekly or biweekly.
When you water your cactus, ensure you're using room-temperature water. Don't use cold water because it can shock the plant and cause the roots to rot. Let the water seep slowly into the potting mix until it's evenly moistened; then empty any excess water from the saucer.
Another thing you have to note is not to use chlorine water. Chlorine should be avoided when it comes to gardening because it can wipe out helpful microorganisms found in the soil, as well as harm the roots of your plants
Treated water usually contains chlorine, which is why some may worry about the effect on their garden. Fortunately, most tap water has harmless levels of chlorine - if you can smell it though, that means there is a higher concentration than average.
Tepid rainwater or filtered water should be used for watering, rather than tap water. This is because the minerals in tap water build up in the soil and can cause deposits on the leaves. Minerals also disrupt the flow of essential nutrients to the plant.
Spring
- Water every 1-2 weeks, allowing the soil to dry out between waterings.
- Increase watering frequency if the weather is particularly warm or if the cactus is actively growing.
- Ensure thorough watering, allowing water to soak into the soil and drain out of the pot.
- Avoid overwatering, as it can lead to root rot.
Summer
- Water every 1-2 weeks, as cacti are actively growing during this season
- Adjust the watering frequency based on the specific needs of your cactus and the temperature.
- Provide adequate drainage to prevent waterlogged soil.
- Consider misting the cactus or providing some shade during hot summer days.
Autumn
- Reduce watering frequency to every 3-4 weeks as cacti enter dormancy.
- Allow the soil to dry out completely between waterings.
- Be cautious not to overwater, as cacti require less moisture during this period.
- Adjust watering based on the specific needs of your cactus and the surrounding environment.
Winter
- Water sparingly, only when the soil is completely dry.
- Water every 4-6 weeks or longer, as cacti are in a rest period during winter.
- Protect cacti from cold drafts and ensure they receive adequate sunlight.
- Avoid watering if the cactus is in a cold environment or if there is a risk of frost.
Remember, the watering frequency of forest or jungle cacti like Dancing Bones cactus is higher than that of desert ones like Joseph's Coat Cactus or Opuntia Rufida Minima, as forest cacti prefer moist roots, unlike desert cacti.

How Much Sunlight Does a Cactus Need?
When growing cacti indoors, they generally need bright, indirect sunlight. Place them near a window where they can receive about 6-8 hours of sunlight per day. If you don't have a sunny spot, you can use artificial grow lights to provide the necessary light.
If your cactus is placed in a spot that doesn't get enough light, it will stretch and become leggy. This is known as "etiolation." To avoid etiolation, place your cactus near a south- or west-facing window. If you don't have a spot like this in your home, you can also use grow lights to provide the plant with the light it needs.
When growing cactus plants outdoors, they typically thrive in full sunlight. They need at least 6 hours of direct sunlight each day to grow and maintain their health. Make sure to choose a sunny spot in your garden or patio where they can soak up the sun.
Remember, cacti are adapted to arid environments, so they can tolerate intense sunlight. However, be cautious of extreme heat during the hottest part of the day, as it can cause sunburn or heat stress. Providing some shade during the hottest hours can help protect your outdoor cacti.
The Right Kind of Cactus Soil Is Highly Important for Optimal Growth
Make sure you are aware of the different types of cactus species and the kinds of conditions they require to grow before you decide to buy one. You should purchase a potting mix suitable for cactus. The majority of garden centers offer the right kinds of cactus mix. You may either purchase a specialized cactus potting mix locally or create your own mixture by adding some sand and grit to the compost portion of the soil to make it grainy and less tightly compacted.
Cacti thrive in aerated, well-draining, light soil. The ideal cactus soil mixture will retain exactly the right amount of moisture to feed the plant without overdoing it.
The ideal potting soil combination is one that dries up rapidly after watering. The soil's moisture content is quickly absorbed by cacti.
Therefore, any excess moisture will start to result in dampness issues and produce mildew, fungus, or rot.
Planet Desert offers specially formulated cactus soil, which has been tested for years.
Our blend includes an organic substrate with mycorrhizae to help develop the root system.
We also added the number of inorganic media needed to help with adequate drainage and ventilation. Additionally, our cactus soil also has a nutrient-rich mineral system perfect for enriching desert plants.
When it comes to fertilizing cacti, it's important to take a gentle and cautious approach. Cacti don't require a lot of fertilizer, so it's best to use less. Once a year, in the actively growing season, during the spring, you can fertilize your cacti with balanced (5-10-5) NPK fertilizers. Dilute the fertilizer to half or quarter strength and apply it to moist soil.
Remember to follow the instructions on the fertilizer package and avoid overfertilizing, as it can harm your cactus. In the dormant season, typically autumn and winter, it's best to avoid fertilizing altogether. Cacti are pretty resilient, so a light touch with fertilizing will help keep them healthy and happy!
Benefits of Cactus Soil:
- Dries out more frequently than general-purpose, peat-based mixes.
- Well, suited for low-light growing conditions & high humidity.
- Less challenging to overwater crops.
- Reduces incidence of water-related problems (root diseases, algae, and fungus gnats)

Finding the Ideal Spot: Temperature Tips for Thriving Cacti
For indoor plants, the temperature hardiness zone is less of a concern since they are protected from extreme weather conditions. Most common houseplants can thrive in a temperature range of 60-75°F. However, it's important to avoid placing them near drafts or heating/cooling vents, as sudden temperature changes can stress the plants. As for humidity, many indoor plants appreciate higher humidity levels. You can increase humidity by placing a tray of water near the plants or using a humidifier.
When growing outdoors, temperature hardiness zones become more important. Hardiness zones are determined by the average minimum winter temperatures in a specific region. They help you choose plants that can withstand the cold temperatures in your area. For example, if you live in zone 5, you'll want to select plants that are hardy to zone 5 or lower. This ensures that they can survive the winter without damage. To make things easier for you, we at Planet Desert described all of our cacti and succulents with accurate temperature and hardiness zones.
In terms of humidity, outdoor plants have varying preferences. Some plants, like tropical species, thrive in higher humidity environments. Others, such as desert plants, prefer drier conditions. It's essential to research the specific humidity requirements of the plants you choose to ensure their optimal growth.
How to Repot Your Flowering Cactus Plants
If your cactus is starting to outgrow its pot, you'll need to repot it into a larger container. Use a pot that's only 2-3 inches wider than the current one; any bigger and the roots won't have enough space to spread out.
- To repot your cactus, remove it from its current pot to place it in the new one. Gently remove it by grabbing around the base of the plant and pulling the pot down.
- Then, backfill the pot with fresh soil mix. Planet Desert creates a potting mix specially formulated for the health of cactus plants, with
- Place your cactus in the new pot and fill it with more cactus mix, making sure not to compact the roots. You will “build up” the roots by holding the plant in place and placing soil around the roots without crushing them.
- Water your cactus, and then allow the soil to dry completely before watering it again.

Overwintering cacti is an important consideration, especially if you live in a region with cold winters. Cacti are typically native to arid and desert environments, so they are not naturally adapted to withstand freezing temperatures. Here are a few tips for overwintering your cactus:
- Bring them indoors: If you have potted cacti, it's best to bring them indoors before the first frost. Find a bright and cool location, such as a south-facing window or a room with plenty of natural light. Keep in mind that cacti still need some dormant period during winter, so avoid placing them in a warm and constantly heated room.
- Reduce watering: During winter, cacti enter a period of dormancy and require less water. Reduce the frequency of watering and only water when the soil is completely dry. Overwatering during winter can lead to root rot, so it's crucial to be cautious.
- Provide proper lighting: Cacti still need adequate light even during winter. Make sure they receive at least 4-6 hours of bright, indirect sunlight per day. If natural light is limited, you can supplement with a grow light to ensure they get the necessary light energy.
Remember, cacti have different temperature and humidity preferences depending on their species. It's essential to research the specific requirements of your cactus to provide the best care during the winter months.
Growing Your Own Desert Beauties: The Art of Cactus Propagation
If your cactus produces offshoots (or pups), they can be used to propagate other plants. Pups typically form at the base of the plant, sharing nutrients and water from the mother plant, while others form along the stem or pads. Harvesting and propagating pups improves the mother plant's health while also allowing you to replicate it.
- Identify the pups: Look for small offsets or baby cacti growing at the base of the parent plant.
- Prepare the tools: Get a clean, sharp knife or shears for separating the pups.
- Separate the pups: Carefully cut or gently twist the pup away from the parent plant, ensuring it has some roots attached.
- Allow the pups to callus: Place the separated pups in a dry, shaded area for a few days until the cut ends form calluses.
- Prepare the potting mix: Use a well-draining cactus or succulent soil mix.
- Plant the pups: Gently place the callused ends of the pups into the soil, ensuring they stand upright.
- Provide proper care: Place the newly planted pups in a bright, indirect light location and water sparingly, allowing the soil to dry out between waterings.
- Monitor growth: Keep an eye on the pups and make sure they are establishing roots and growing.
- Gradually increase sunlight: Once the pups have rooted and started growing, gradually expose them to more sunlight.
- Enjoy your new cacti: Once the pups have grown into healthy plants, you can proudly display them in your home or garden!
How to Keep Your Cactus Away from Pests
- You can opt to use neem oil to control pests such as aphids, mealybugs, and scale insects. These solutions should be applied every 7-10 days until the problem is under control.
- Neem oil solution can be applied to the cactus either for prevention or treatment by using three methods: direct spraying, soil drenching, and deep soaking.
- Always test a small portion of the cacti before using the solution on the whole plant to check if it can cause damage.
- The mixture should only contain 0.5 to 1% of crude neem oil to prevent the burning effect on the plant caused by too much azadirachtin.
- However, if you use a refined neem oil (lesser azadirachtin content), you can mix up to a 2% solution (6 tbsp neem oil) to get the same effect.
- Another helpful tip to prevent pests is, it's essential to quarantine new plants before you add them to your collection. This will help prevent the spread of pests and diseases. Place new plants in a separate room or area for at least 2-3 weeks before giving them the all-clear.
Avoiding Common Problems: Caring for Your Cacti
- Overwatering: Cacti are adapted to dry conditions, so it's important to avoid overwatering. Allow the soil to dry out completely between watering and be cautious during the dormant season.
- Poor Drainage: Cacti need well-drained soil to prevent root rot. Make sure to use a mix specifically formulated for cacti or add perlite or sand to improve drainage.
- Lack of Sunlight: Cacti love sunlight! Make sure they receive enough bright, indirect, or direct sunlight depending on the species. Insufficient light can cause them to become weak and leggy.
- Incorrect Pot Size: Choosing the right pot size is important. Cacti prefer snug pots with good drainage. A pot that is too large can retain excess moisture, leading to root rot.
- Overfertilizing: Cacti don't require a lot of fertilizer. Avoid overfertilizing, as it can cause damage. Stick to a specialized cactus or succulent fertilizer and follow the instructions.

What makes a cactus unique from other plants?
Cacti are unique from other plants in several ways! Here are a few key characteristics that make cacti stand out:
- Succulent Adaptations: Cacti have thick, fleshy stems that store water, allowing them to survive in arid environments with limited rainfall. This adaptation helps them withstand long periods of drought.
- Spines instead of Leaves: Unlike most plants, cacti have modified leaves called spines. These spines serve multiple purposes, including reducing water loss by providing shade and protecting the cactus from herbivores.
- Unique Shapes and Sizes: Cacti come in a wide variety of shapes, sizes, and textures. Some have tall, columnar forms, while others have low, sprawling growth habits. These unique shapes help them maximize water storage and minimize exposure to the intense desert sun.
- Aeroles: Cacti have areoles, cushion-like structures with trichomes, which are clusters of small bumps that allow for the growth of spines, flowers, branches, and leaves.
Overall, cacti have evolved remarkable adaptations to survive in harsh desert environments, making them truly unique and fascinating plants!
