How To Care For Rhipsalis
Taking care of Rhipsalis cacti is super easy and doesn’t require any magic tricks. The key is to find the right balance when it comes to watering. These cacti don’t want to be too wet or too dry. Along with watering, the plant substrate and the right location are important factors to consider. Rhipsalis plants are like rainforest dwellers—they prefer bright but indirect sunlight, seeking shade under large trees. It’s important to note that they don’t like direct, bright sun. Also, avoid fertilizing them in winter; wait until the flowers bloom. And the best part is, you don’t have to worry much about trimming these cacti unless there are damaged or excessively long parts that need removal.
Rhipsalis doesn’t hibernate and can tolerate warm and bright conditions while needing only a little watering. If you want to expand your Rhipsalis family, you can propagate them through cuttings. Simply select healthy shoots, let the cuts dry for a few days, and then plant them in a suitable container. Disease occurrence is rare if you care for them properly. However, pests like mealybugs can be a nuisance, especially during winter. Keep an eye out for these fluffy white pests and take action as soon as you spot them.
Finding the right spot for your Rhipsalis is essential. They enjoy a bright location, but be careful not to expose them to direct sunlight. While they can handle morning and evening sun, direct afternoon sun can be a bit too harsh for their delicate nature. So, a partially shaded location is perfect, allowing them to thrive without getting sunburned.
Rhipsalis loves the indoors and can stay in a normal living room all year round. However, during the summer, they can be safely placed outdoors, as long as they are protected from intense sunlight, wind, and rain. These plants appreciate slightly higher humidity, so if you can provide that, they’ll be even happier.
Soil and Planting
When it comes to the soil, Rhipsalis has its preferences. Normal potting soil doesn’t suit them well. You can use commercially available cactus soil, but it’s more economical and better to mix it yourself. Don’t worry; it’s not complicated. You can follow a simple recipe to make the perfect soil mix for your Rhipsalis.
When planting or repotting your Rhipsalis, handle the delicate roots with care. It’s best to do this in spring, although it’s possible to plant or repot before autumn too. After removing the cacti from their substrate, clean the vessel, fill it with fresh soil, and place the cactus back in. Remember that Rhipsalis roots are usually small, so larger vessels are rarely necessary.
To encourage overhanging growth and even development, make sure the plant has space on all sides. You can rotate the vessel regularly, whether it’s a hanging basket or a regular pot. This way, all sides receive enough light for continuous growth and uniform appearance.
Watering Rhipsalis requires a gentle touch, considering the season and the cactus’s needs. It’s crucial to avoid letting them completely dry out, but at the same time, excessive watering should also be avoided. Always allow the surface to dry thoroughly before watering, especially during the main growing season in spring and summer. In autumn, reduce the amount of water significantly. In winter, water very moderately. Rhipsalis cacti are sensitive to lime, so it’s recommended to use very soft water, preferably rainwater. Don’t forget to ensure sufficient humidity, especially by using an evaporation container nearby.
To encourage buds to form, fertilize your Rhipsalis every 14 days until some of the buds have opened. Fertilizing during the blooming season can provide extra nourishment to promote healthy growth and beautiful flowers.
Usually, Rhipsalis doesn’t require much pruning. However, if your plant becomes too big or you notice damaged or excessively long parts, you can trim them without any problems. These cut-off shoots can even be used for propagation. When trimming, choose the cuts strategically to ensure aesthetics, making them less visible or ending them where a joint naturally occurs. Even shoots with spots or damage can easily be trimmed using clean and preferably disinfected cutting tools to prevent the introduction of pathogens.
Unlike many other cacti, Rhipsalis doesn’t hibernate. However, it’s important to note that they are not hardy and cannot survive in outdoor conditions. During winter, you can place water-filled bowls near radiators to maintain sufficient humidity. Regularly check for pests, especially when humidity levels are low. It’s best to water your Rhipsalis a little, ensuring it doesn’t dry out completely. Avoid fertilizing or repotting during this period, allowing the plant to rest and conserve energy for the upcoming growing season.
Diseases and Pests
When you provide proper care conditions, Rhipsalis rarely experiences diseases. However, overwatering can cause root rot. On the other hand, pests can be a nuisance, particularly during winter. Mealybugs are the main culprits that bother Rhipsalis. These pests can be identified by fine, white webs and small, cotton-like structures on the plant. They suck out the sap and can cause significant damage.
If you spot mealybugs, it’s important to isolate the infected plant to prevent them from spreading. Systemic agents that are absorbed by the plants work best for controlling mealybugs. However, keep in mind that Rhipsalis may not tolerate these treatments well, so use them with caution.
How to Propagate Rhipsalis Cacti
Rhipsalis can be propagated through cuttings and seeds. Here are the steps for each method:
Propagation by Cuttings
- Select healthy shoots that are around 3 to 6 inches long.
- Allow the cuts to dry for a few days.
- Plant the cuttings in a suitable medium, about 1.5 inches deep.
- Place them in a bright location, but avoid direct sunlight.
- Maintain temperatures between 68 and 77 degrees Fahrenheit.
- Keep the medium slightly damp, and cover the container with a transparent plastic bag to maintain high humidity.
- Ventilate the container daily to prevent mold growth.
- After 3 to 4 weeks, roots should have formed, and the young plants can be treated as usual.
Propagation by Seeds
- Extract the seeds from ripe and soft fruits by mashing and separating them from the pulp.
- Alternatively, open the fruit and let it dry in sand. Roughly free the seeds from the pulp before rubbing the sand to separate them.
- The best time for seed propagation is from June to mid-August.
- Use a mixture of herb soil and fine pumice gravel as a medium.
- Place the seeds on the surface and lightly press them without covering with soil.
- Keep them in a partially shaded area.
- Maintain temperatures between 68 and 82 degrees Fahrenheit.
- Keep the medium evenly moist.
- Germination can occur throughout the year in a well-lit and heated greenhouse.
Remember to be patient as seed propagation can be more challenging than using cuttings.
Frequently Asked Questions
Are Rhipsalis toxic to cats and dogs?
When it comes to Rhipsalis cacti, their toxicity to cats and dogs is still uncertain. It’s best to err on the side of caution if you’re unsure about their effects on your furry friends.
The tricky part is that Rhipsalis cacti are often mistaken for Euphorbia, which is also known as the spurge. Some types of Rhipsalis closely resemble these plants. However, the key difference is that Rhipsalis cacti don’t release the white sap that’s characteristic of spurge plants when they’re cut. This makes them less likely to cause skin irritation.
While not all spurge plants are toxic, their sap can irritate the skin of many people and may cause discomfort, stomach cramps, and vomiting if ingested.
