Your Prickly Companions | A Beginner's Guide to Growing Happy Cacti
Hello friends, I hope there are some cactus lovers on STEEMIT, because today's article will focus specifically on cacti.
As someone who has kept various cactus varieties as houseplants for years, I have learned a lot about these resilient desert succulents through hands-on experience. In this post, I will cover the basics of cactus care by outlining the considerations for proper watering, lighting, soil, and other maintenance needs. With their low water requirements and hardy nature, cacti make wonderful plants for beginners or anyone wanting to add a touch of the tropics or desert to their home. Let's get started!
Introduction to Growing Cacti
Cacti come in an amazing variety of shapes, sizes, and appearances and can add unique texture and visual interest to any indoor or outdoor garden space. Known for their ability to thrive in hot, dry conditions with little water, cacti are some of the easiest and most low maintenance houseplants you can care for. Whether you want a collection of quirky mini cactus plants or a larger specimen to anchor a room corner, there is a cactus for every environment and gardening interest.
While some may think of cacti as nothing more than prickly plants meant for very hot, arid zones, many varieties do beautifully if given the proper care inside the home. My favorite types for indoor growing includeaste specimens for a burst of vibrant color all year long. Now let's dive into the specifics of selection, care and maintenance.
Selecting the Right Cactus
When starting your cactus collection, it's important to understand the different varieties so you can choose plants suited to your growing conditions and preferences. Broadly speaking, cacti fall into two main types - desert or jungle species. Desert cacti like barrel cacti and prickly pears typically need very warm, dry conditions while jungle cacti including Christmas and Easter cacti tolerate more humidity and occasional rainfall.
It's also crucial to consider if the cactus will be grown indoors or outside. Many small cactus varieties with slender stems like rat tail cacti are well-suited to windowsills and desks. Larger types meant for landscapes include san pedros, agaves and hedgehogs. Regardless of variety, assess factors like mature plant size, sunlight and temperature needs before deciding what works best for your space. Proper planning results in happy, healthy cacti!
Choosing the Right Soil
Now that you’ve selected your cactus varieties, it’s time to prepare the right soil mix. Unlike typical houseplants, cacti thrive in very well-draining soil that dries out rapidly between waterings. My go-to recipe includes 2 parts inorganic minerals like pumice or perlite to 1 part organic potting mix. This allows for moisture and oxygen circulation around the roots while providing structure. Using the wrong, moisture-retentive potting soil is a leading cause of root rot.
For containers, choose terracotta or plastic pots with large drainage holes. Avoid glazed ceramic that retains too much moisture. Larger pots give roots room to grow but don't go up in size too fast as cacti appreciate being slightly rootbound. Follow these soil fundamentals and your spiky companions will feel right at home!
Watering Techniques
With their desert roots, cacti are designed to go long periods without water and their number one killer is overwatering. As a general rule, wait until the soil is dry 1-2 inches deep before watering again, which may be every 2-4 weeks depending on conditions. Growing cacti indoors where light levels and temperatures fluctuate less means watering even less frequently in winter.
I recommend checking the soil moisture with your finger before watering and giving thorough soakings when you do water until it runs out the drainage holes. Avoid misting which leads to rot. For established plants, watering once monthly may suffice. During their slower growing season over winter, cut back water even more. Learning a cactus' individual water needs with experience helps you keep them comfortably on the dry side.
Providing Adequate Light
Light is key for healthy cactus growth and determining where to position your plants. Those grown outside from spring to fall will appreciate full, direct sun for at least 6 hours daily. But Texas Lady and Easter cacti tend to scorch in too much summer sun and benefit from morning light dappled through trees.
For indoor conditions, place plants in a south or west-facing window if possible. Supplement with grow lights in low-light areas to keep spines and new segments developing properly. Some stretchiness is normal without optimal light but too little and plants lose their characteristic cactus shape over time. Rotate pots occasionally so all sides receive evenly bright illumination.
Temperature and Humidity Considerations
Most cacti and succulents thrive in warm conditions between 65°F to 80°F ideal. They can take limited dips below freezing for short periods if completely dry. During active growing seasons, slightly higher temps spur faster growth. Humidity levels below 50% are preferable though jungle cacti like thanksgiving and Easter cacti handle moderate humidity of 50-60% with proper drainage and airflow.
For colder zones, move containerized plants to a sunny, sheltered patio or inside before first frosts. Or create a mini greenhouse using plastic sheeting held a few inches above plants with PVC hoops. Proper hardening off is required before moving tender varieties in and out of lower humidity, indoor conditions.
Feeding and Fertilizing
While they can survive for long stretches without, cacti also do appreciate an occasional nutrient boost to encourage healthy spines, segments and vibrant coloration. A dilute, balanced liquid fertilizer designed for succulents or orchids works well and can safely be applied during the growing seasons of spring through fall.
I favor a diluted formula of around 1⁄4 the strength listed on the label and only every 4-6 weeks when the soil is dry and plants are actively growing. Excess fertilizer risks burning roots. It's easy to overlook feeding with their slow growth, but a little TLC goes a long way towards building strong, long-lived specimens.
Propagation and Maintenance
In addition to their easy care habits, cacti make terrific plants to propagate yourself and expand your collection at no cost. Remove offsets or pads with a clean, sharp knife and allow cuts 3-7 days to callous before planting. Gently lay cuttings on well-draining soil and keep warm and dry until roots emerge, usually several weeks.
Pruning may be needed occasionally to shape and remove dead or broken sections. Use clean shears and let cuts heal before watering recently pruned areas. Common pests include mealybugs, scale and spider mites. Isolate and wipe affected areas with isopropyl alcohol or insecticidal soap. Rare fungal or bacterial crown issues may arise—avoid overhead water and use a fungicide if needed.
With just a bit of understanding and customized care, you'll be growing your own collection of happy, healthy cacti in no time! I hope these basics help give you the confidence to nurture these resilient plants indoors or out. Let me know if you have any other questions!
