Cactus leaves are known as “phylloclades”, which are modified stems. These swollen structures are not true leaves, since the leaves of most plants are flat, thin structures specialized for gaseous exchange and photosynthesis.
Phylloclades do not have the same veins or stomata that true leaves would have, but instead have tough external surfaces and are better suited for absorbing and storing water. These structures are found on some cacti species as well as many other related succulent plants.
Unlike true leaves, phylloclades are typically thick and fleshy, with small spines or hairs. These adaptations are effective for preventing water loss in hot, arid environments.
What are the parts of a Christmas cactus?
The Christmas cactus (Schlumbergera bridgesii) is a popular winter holiday houseplant with a unique and stunning appearance. The species features flat, leaf-like segments known as “phylloclades” that can range in color from deep burgundy to glossy green.
When the plant is in bloom, it produces vibrant pink, purple, or white flowers. The Christmas cactus is low-maintenance and relatively easy to care for, making it a great addition to any home.
The Christmas cactus can be broken down into three main parts: the leaves/phylloclades, the flowers and the stems. The leaves/phylloclades consist of long, flat segments with scalloped or jagged edges.
The bright colors of these segments draw the eye of those who view the plant.
The flowers of the Christmas cactus are what make the plant so unique and beautiful. The showy blooms can be red, purple, pink, or white and often tinged with a hint of yellow near the edges. These flowers can continue to appear sporadically throughout the winter season, appearing in clusters or sprays on the end of stems or clustered near the tips of the phylloclades.
Finally, the stems of the Christmas cactus are thin, wiry and green, typically growing from the tips of the phylloclades. The flowers will usually be found at the tips of these thin stems, but the whole plant may also be made up of shorter stems that branch off the main stem.
These shorter stems can give the Christmas cactus a cascading look that many find very attractive.
All of these parts – the leaves/phylloclades, flowers, and stems – come together to create the distinct and eye-catching appearance of the Christmas cactus. Together, they make this plant a beloved holiday houseplant that can be enjoyed throughout the colder months of the year.
What do Christmas cactus new leaves look like?
Christmas cactus new leaves have an iconic pointed shape and feature a bright, vivid green hue. These foliage have broad segments that taper up to form a point. Their leaves can range in width from 1-4 inches and typically grow 1-4 inches long.
Depending on the variety, the leaves may have light colored fur coating the underside, giving them a soft, fuzzy texture. The texture of the leaves also serves to help protect the plant from prolonged exposure to harsh sunlight and drying winds.
How do I know what kind of Christmas cactus I have?
To identify what type of Christmas cactus you have, look for some key characteristics. The Christmas cactus is a tropical plant that comes in many varieties, but can be divided into two distinct species – Schlumbergera truncatus and Schlumbergera bridgesii.
Schlumbergera truncatus is sometimes referred to as the Thanksgiving cactus and is characterized by a more triangular shape to the leaves, usually with flattened edges. The flowers of the Thanksgiving cactus are more rounded in shape and come in a variety of colors such as red, yellow, white, peach, and purple.
Schlumbergera bridgesii is sometimes referred to as the Christmas cactus and has more curved and scalloped leaves, often with serrated edges. The flowers are generally star-shaped and come in a variety of colors such as red, yellow, white, and pink.
Knowing which species of cactus you have can help you better care for your plant, as each species has different light and watering requirements. If you are still uncertain, you can take a sample of your cactus to a local garden center or nursery and have it identified by a knowledgeable staff member.
Is a Zygo cactus the same as a Christmas cactus?
No, a Zygo cactus is not the same as a Christmas cactus. The Zygo cactus (or Zygocactus truncatus) is a tropical cactus variety that is native to the rainforests of South America, while the Christmas cactus (also known as Schlumbergera truncata or Schlumbergera bridgesii) is native to the mountainous regions of Brazil.
While both feature prolific blooms and succulent green stems, the Zygo cactus is a terrestrial cactus with vibrant magenta blooms, while a Christmas cactus is an epiphytic cactus featuring blooms of red, white, and pink.
Moreover, the Zygo cactus typically blooms towards the end of the summer, whereas the Christmas cactus can begin to flower from late autumn onwards.
What is the difference between false Christmas cactus and Christmas cactus?
The Christmas cactus (also known as a Thanksgiving cactus, or a Crab cactus) is a species of plant native to Brazil, and is most commonly associated with the holiday season. The Christmas cactus typically blooms with vibrant pink or red flowers at the same time of year that Christmas celebrations take place.
The false Christmas cactus, also known as the crab cactus or Thanksgiving cactus, is a closely related species but is native to the Central and South American tropics. Both species of cacti have the same flattened, segmented stems, but they differ in the shape of their pads and their flowers.
The Christmas cactus has longer, more pointed pads and flowers that hang down more. The false Christmas cactus has more rounded pads and more upright flowers. The flowers of the false Christmas cactus also tend to be more varied in colour, while the flowers of the Christmas cactus are usually bright pink or red.
While both species of cactus will make your home brighter during the holiday season, it’s easy to tell the difference once you know what you’re looking for.
How do you fix a limp cactus?
Fixing a limp cactus can be a tricky endeavor, but it is definitely possible with a little bit of know-how and some patience. First, you can start by gently shaking and rotating the cactus to check for damage or weak joints.
If they are too weak and bendy, then the plant might need to be propped up properly so the stem can gain its full strength. You can do this either by using a stake, a pencil, a chopstick, or another similar item to prop it up.
When using stakes, make sure to add enough support for the cactus to stay upright. If the limbs are damaged, consider lightly wiring them together to hold them in place.
If this does not work, there are some products sold at garden stores that help rebuild the strength of the cactus by allowing for water absorption. If the limp cactus is a result of over watering, reduce the amount you water it and let the soil dry out, as cacti can be particularly sensitive to moisture and are prone to root rot.
If your cactus is receiving too much direct sunlight, consider moving it to a shadier spot, as that could be drying it out too quickly. Finally, make sure to provide your cactus with the right type of fertilizer and proper soil, as these are key factors to ensuring your cactus grows into a healthy, vibrant plant.
How often should you water a Christmas cactus?
Christmas cacti require very little water and should be watered only when the soil is completely dry. Generally, this is about once a week during the summer months and once every two to three weeks during the winter months.
Make sure to check the soil to ensure it’s dry before adding any additional water. Overwatering can cause root rot, which will damage the plant and could eventually lead to its death. Christmas cactus is also very susceptible to soggy soil, so if you notice the soil becoming overly moist, wait a few days before watering again to ensure the water has time to fully absorb into the soil.
Why has my cactus gone floppy?
Depending on the type of cactus, it may be a sign that it needs more water or fertilizer. Where you have placed the cactus may also be a factor – if it is in a place that is too damp, too sunny or too cold, it might lead to the cactus becoming floppy or wilted.
Other reasons may include your cactus being root-bound in its pot, i. e. it has outgrown its root space, or it may be infested with pests or disease, or it even may have been recently repotted.
It’s best to check the soil moisture level and investigate the environment your cactus is in. Make sure it is in an area with bright, indirect sunlight and the temperature is between 10-30°C. If you have recently repotted, you may need to water more frequently until it has settled in.
If necessary, you can fertilize it with a tiny amount of diluted cactus food. Lastly, make sure there are no signs of pests or disease, such as aphids or mealybugs, and that the cactus is not being over-watered.
How can you tell if a Christmas cactus is overwatered?
You can tell if a Christmas cactus is overwatered by looking for some certain signs. The first and most obvious sign is that the leaves of the cactus will begin to wilt and droop. The soil will also become wet and soggy, and left standing water may be present.
Other signs of overwatering include the leaves turning yellow or brown, and there may be white or dark spots on the leaves. If the Christmas cactus is severely overwatered, the roots will begin to rot and a sour, unpleasant smell may also be present.
To avoid overwatering, make sure to water the Christmas cactus only when the top inch of soil is dry and avoid using a heavy pot that does not have drainage holes in the bottom.
Will an overwatered cactus recover?
In most cases, yes, an overwatered cactus can recover. However, if the plant has been overly saturated with water, it may be too late to save it. To tell if a cactus is overwatered, check the end of its leaves; if they are soft, black, and mushy then it is likely in too much water.
If the cactus is not yet beyond saving, the best course of action is to stop watering it, repot the cactus in well-draining soil, sufficient sunlight, and proper ventilation. Make sure you only give the cactus enough water to saturate the soil without causing an excess or any standing water.
Additionally, adding some compost or fertilizer to the soil can help the roots recover. With consistent, diligent care, it is still possible to revive an overwatered cactus.
Do you water a Christmas cactus from the top or bottom?
When watering a Christmas cactus, it’s best to water it from the bottom. This is done by placing the pot in a shallow container with about an inch of lukewarm water in the bottom and allowing the roots to soak up the water.
Once the soil has taken on a nice dark color and the excess water has drained, the plant can be removed from the tray. This method of bottom watering helps to reduce the likelihood of root rot developing and helps keep the foliage dry and pest-free.
Additionally, watering from the bottom helps to avoid over-watering the plant and only wetting the soil when the roots need it, which can save a bit of water in the long run.
How do you tell if Underwatering vs overwatering?
One way to tell if your plants are being underwatered or overwatered is by examining the soil. Underwatering will cause the soil to be dry and hard, while overwatering will cause the soil to be damp and compacted.
Other signs of underwatering are when the leaves of the plant change color or become brittle and start to drop off, while signs of overwatering are when the leaves become wilted or turn yellow. Additionally, the roots of a plant that is being underwatered can be stunted, while those of an overwatered plant can start to rot.
Lastly, if you have an indoor plant, check the potting mix since underwatered soil will not hold onto moisture while overwatered soil will be waterlogged.
Can a Thanksgiving cactus bloom at Christmas?
Yes, a Thanksgiving cactus can bloom at Christmas. Thanksgiving cacti are tropical plants that bloom during the winter, usually beginning in late autumn and continuing through early spring. Depending on the conditions of their environment, such as the amount of light and water they receive, they may start flowering a bit earlier in autumn or as late as early winter.
While it may not be the traditional Christmas look, the velvety petals of a Thanksgiving cactus can bloom around the holiday season and give any winter gathering a lovely and festive accent.
How do you tell a Christmas Thanksgiving and Easter cactus apart?
Christmas cacti have pointed petals and generally have flat, star-shaped flowers while Thanksgiving cacti have more scalloped-shaped petals. Easter cactus have segmented, pointed petals. The time of year they bloom is also a clue, as they are named for the holiday they bloom near.
Christmas cacti will typically bloom in December, Thanksgiving cacti in November and Easter cacti in March or April. Each cactus has its own care requirements, so it is important to know which type you have so you can provide the proper care and encouragement for them to bloom.
Should I deadhead Thanksgiving cactus?
Yes, you should deadhead Thanksgiving cactus for optimal growth. Deadheading is the process of removing spent blossoms from the plant. This helps the plant to focus its energy on producing more blooms instead of on the spent blossoms.
When the flowers have faded and wilted, use a sharp, clean pair of pruning shears to clip the flower just above the joint where it meets the stem. It’s important to make sure cut is as close to the stem as possible to avoid leaving a stub.
When deadheading, you should also trim any old and damaged stems from the plant. This will encourage it to fill in and develop into a bushier shape. The Thanksgiving cactus should be deadheaded every season, however, it doesn’t need to be done right away – it’s perfectly fine to wait several weeks after the blooms have faded away.
Is there an Easter Cactus like the Christmas cactus?
Yes, there is an Easter cactus, just like the Christmas cactus. The Easter cactus (Rhipsalidopsis gaertneri) is a member of the same family as the Christmas cactus (Schlumbergera), making them closely related despite looking quite different.
The differences in appearance are mainly due to their size. The Easter cactus typically grows much smaller in size than the Christmas cactus. However, the Easter cactus features the same beautiful flowers of various colors, such as yellow, pink, and red.
The Easter cactus should be placed in bright, indirect sunlight and can thrive best in temperatures between 60 and 75 degrees Fahrenheit. Furthermore, the Easter cactus should not be overwatered and should be allowed to dry out before being watered again.
With these tips, you can enjoy the beauty of the Easter cactus in your home.
