Flowering Season in Australia
The Zygocactus floral fiesta starts as the days grow shorter and the air turns cooler! These delightful blooms make their grand entrance from late autumn to winter. In Australia, you can expect these beauties to bloom between April and July during which the cooler temperatures and those shorter daylight hours create the perfect condition for flowering.
Nurturing Zygocactus Blooms
The allure of Zygocactus plants lies in their dazzling blooms, so here are some tips on how to coax out those vibrant flowers:
Bud Development
- Expose Zygocactus to cooler temperatures at night during the bud development stage to stimulate blooming. Ideal blooming temperatures typically range from 10℃ to 15℃.
- These plants thrive on stability, so avoid any sudden changes in light exposure or temperature.
Prolonging Blooming Periods
- Give Zygocactus a makeover by gently pinching off old flowers at the base of the stem. This also encourages fresh buds.
- Once the plant is blooming, make sure it is regularly watered, but do not fertilise as it is not actively growing during winter.
Post-Bloom Care
- Just because the blooms have taken their final bow for the season doesn’t mean the care stops there. Maintain good growing conditions all year-round to ensure those blooms return!
Essential Care Tips
While Zygocactus plants are undeniably tough and low maintenance, they do have their preferences when it comes to growing conditions. These nurturing tips can result in a healthy plant that can even live for 50 years!
Lighting
- Zygocactus thrive in bright, indirect light to promote healthy growth and blooming. Avoid placing them in direct sunlight, especially during the peak heat of the day. Too much sun exposure can lead to leaf burn or browning.
Watering
Temperature
- Maintain moderate temperatures between 15°C to 21°C during the day. Slightly cooler temperatures at night, especially during the bud development stage, can work wonders in coaxing out those breathtaking blooms. Think of it as a bedtime ritual for your plant – cooler nights, brighter blooms!
Soil
- Plant Zygocactus in a well-draining potting mix containing perlite, sand and coir peat to create the perfect balance for optimal drainage. Remember, good drainage is key to keeping your Zygocactus happy and healthy, and the right foundation is essential!
Fertilisation
- While Zygocactus are not heavy feeders, a little boost during their growing season can work wonders. Opt for a gentle fertiliser specifically formulated for flowering plants to give them the nutrients they need to thrive. Remember, moderation is key and avoid over-fertilising.
Humidity and Air Circulation
- Good air circulation is also important and these plants prefer some breathing room to thrive. If the environment tends to be on the dry side, boost humidity levels with a humidity tray or a sprinkle of mist now and then.
Planting and Potting
Getting the planting and potting just right is crucial for Zygocactus to thrive. When it comes to choosing the right container, opt for a pot with drainage holes at the bottom. This ensures excess water can make a swift exit, preventing soggy soil and dreaded root rot. Pot size also matters! Choose a pot that is a little larger than your plant’s root ball. Those roots prefer some room to stretch and grow, but not too much that they’re swimming in excess moisture.
Potting New Zygocactus
- Laying the Foundation: Start by adding a layer of potting mix to the bottom of your chosen pot.
- Centre Stage: Gently place the plant in the centre of the pot, making sure to spread out those roots evenly.
- Fill ‘er Up: Fill in the gaps around the roots with more potting mix and press down lightly to secure the plant in place.
- Hydration Station: After all that potting action, give the pot a good soak with some water to settle the soil and help those roots make friends with the potting mix.
Repotting Zygocactus
These plants will need to be re-potted every 2-3 years or when they outgrow their current pot. Look out for roots sneaking out of the drainage holes, roots that seem too crowded, or if growth has hit a snag, this means it’s time for a change!
- Timing is Key: When it comes to repotting, timing is everything. Aim for spring or early summer when Zygocactus is in its growth phase. This gives it the best shot at bouncing back from the repotting process.
- Handle with Care: Treat the plant gently when coaxing it out of its current pot, making sure not to damage the roots and stems. If the roots are snug, give them a gentle massage to encourage new growth.
- Give it Some Space: Repot the plant in a slightly larger pot filled with fresh potting mix. Keep the soil level consistent with its previous digs and give it a light pat-down around the roots for stability.
- Quench the Thirst: After repotting, give the plant a gentle but good soak to help settle the soil and kickstart those roots on their journey to establishment.
Propagation Techniques
You can easily propagate Zygocactus plants using two simple methods, using stem cuttings or simply division.
Stem Cuttings
- Select with Care: Choose a healthy, mature stem from the parent plant, making sure it is free from any signs of disease or damage.
- Snip Away: With clean, sharp scissors or pruning shears, cut a section of stem that’s about 7.5-15 cm long.
- Time to Dry: Let the cutting sit in a warm, dry spot for a few days to allow it to form a callus. This helps prevent rotting down the line.
- Planting Party: Once the cutting has callused, plant it in a well-draining potting mix. Bury about one-third of the stem (2.5 cm deep) in the soil. A rooting hormone is typically not necessary.
- Stay Moist, Stay Bright: Keep the soil lightly moist and place the cutting in a warm, bright spot with indirect sunlight.
- Watch patiently: Within a few weeks to a couple of months, roots should begin to develop, indicating successful propagation.
Division
This is another effective method, especially when the plant has become crowded or outgrown its pot.
- Gentle Separation: Carefully remove the plant from its pot, making sure not to disturb the roots or stems.
- Spot the Segments: Identify natural divisions within the plant where stems are growing together.
- Cutting Time: Using scissors or pruning shears and gently separate these divisions into individual segments, ensuring that each segment has its own roots and stems.
- New Digs: Plant each division in its own pot filled with fresh potting mix. Keep the soil well-draining and position the plant at the same depth as it was in the original pot.
- Settle In: Lightly water the divisions and place the pots in a cozy spot with indirect sunlight.
- Watch patiently: As with the other method, the divisions should establish roots and begin to grow within a few weeks to a couple of months.
Pets
When it comes to furry friends, Zygocactus is generally considered non-toxic to cats and dogs. This means that if your curious companions happen to take a nibble, it is unlikely to result in severe poisoning or harmful effects.
Thanksgiving Cactus vs Christmas Cactus vs Easter Cactus
Now let’s unravels the mystery surrounding the different names attributed to Zygocactus! While Thanksgiving Cactus, Christmas Cactus and Easter Cactus are often used interchangeably, each variety has its own unique characteristics and are named after when they typically start blooming in the Northern Hemisphere. These three varieties may share some similarities, such as their stunning blooms and resilience, but each has its own distinct blooming season and characteristics. Here’s the lowdown:
Schlumbergera Genus
First things first, let’s clear up the confusion. Schlumbergera is the genus name, and Zygocactus is another name for the species Schlumbergera Truncata, or the Thanksgiving Cactus.
Thanksgiving Cactus (Schlumbergera Truncata or “Zygocactus”)
- Blooming Period: In the Northern Hemisphere, these varieties typically bloom around November, coinciding with the American Thanksgiving holiday. However, here in Australia, Zygocactus varieties typically start flowering in April/May.
- Leaf Shape: Zygocactus has flattened stem segments with scalloped edges adorned with pointed teeth.
- Bloom Characteristics: Flowers typically tend to have pointed tips.
- Growing Habit: Thanksgiving cactus has an upright growth habit.
Christmas Cactus (Schlumbergera Bridgesii or Schlumbergera x Buckleyi)
- Blooming Period: The Christmas Cactus typically blooms in late autumn to early winter, or around Christmas time in the Northern Hemisphere. In Australia, you can expect its blooms in April/May.
- Leaf Shape: Christmas Cactus has flattened stem segments with rounded, scalloped edges and fewer pronounced teeth compared to its Thanksgiving counterpart.
- Bloom Characteristics: Flowers are usually more rounded.
- Growing Habit: Christmas Cactus has a trailing or pendulous growth habit, gracefully cascading over the edges of its container.
Easter Cactus (Rhipsalidopsis Gaertneri or Hatiora Gaertneri)
- Blooming Period: The Easter Cactus bursts into bloom during the spring season, coinciding with Easter time in the Northern Hemisphere. In Australia, blooms appear around September.
- Leaf Shape: Easter Cactus has more rounded stem segments with finer teeth along the edges compared to its holiday counterparts.
- Bloom Characteristics: Flowers are often smaller and more delicate compared to Thanksgiving and Christmas Cacti.
- Growing Habit: Easter Cactus has an upright or slightly pendant growth habit.
The takeaway is that while all three holiday cacti have similar care requirements, including bright, indirect light, well-draining soil and regular watering during the growing season, they can be distinguished by their blooming periods, leaf shapes and bloom characteristics.
Troubleshooting Common Zygocactus Problems
Even the toughest plants like Zygocactus can hit a bump in the road sometimes as all living organisms do. We will wrap up our care guide with these tips to help address some common problems:
