Did You Know?
1. The Christmas cactus (Schlumbergera) can turn purple due to a phenomenon called “anthocyanin pigmentation.” This is when the plant produces pigments called anthocyanins, which can give the cactus a purple or reddish hue.
2. Contrary to its name, the Christmas cactus is not actually a cactus but belongs to the family Cactaceae. It is native to the cloud forests of Brazil, where it grows as an epiphytic plant, attaching itself to trees and rocks.
3. The Christmas cactus has the unique ability to rebloom using photoperiodism. This means the plant requires specific periods of light and dark to initiate bud formation. In nature, this typically occurs during the shorter days of late autumn, but indoor conditions can be manipulated to encourage blooming at different times of the year.
4. While purple is a common color for the Christmas cactus, it can also bloom in a wide range of colors such as white, pink, red, orange, and even bi-colored varieties. The intensity of colors can vary based on environmental factors and the specific cultivar.
5. The Christmas cactus is often considered a symbol of resilience and adaptability. It can survive in low-light conditions and is known for being a relatively low-maintenance houseplant. With proper care, it can live for several decades and bring joy with its beautiful blooms during the holiday season.
Nutritional Issues: Lack Of Fertilization Or Magnesium
When your Christmas cactus starts displaying purplish leaves, it is a clear indication of a potential issue related to nutritional deficiencies, such as a lack of fertilization or magnesium. These vital elements are crucial for the healthy growth and development of plants, and their absence can result in changes in foliage color.
To address this problem, it is important to provide your Christmas cactus with the necessary nutrients. Regular fertilization is key, and using a general-purpose indoor plant fertilizer specifically formulated for cacti can help replenish the missing nutrients. Additionally, supplementing with Epsom salts, which contain magnesium, can also be beneficial. You can dissolve Epsom salts in water and use it as a feeding solution to restore the magnesium levels in the plant, ultimately aiding in the correction of the purplish hue of the leaves.

Fertilization And Epsom Salt Feeding
To ensure the health and vitality of your Christmas cactus, providing adequate fertilization is crucial. This perennial plant benefits from regular feeding, especially during its active growing period. By employing a general-purpose indoor plant fertilizer, you can provide the essential nutrients required for optimal growth. Remember to follow the recommended dosage instructions on the fertilizer package to avoid overfeeding, which could result in further complications.
In addition to fertilization, supplemental feeding with Epsom salts dissolved in water can have a positive impact on the coloration of the cactus leaves. Epsom salts contain magnesium, a vital element that aids in chlorophyll synthesis. By incorporating this feeding regimen into your plant care routine, you can help counteract the purplish tinge on the leaves and promote healthier and greener foliage.

Rootbound Plants And Purple Leaves
Another factor that may contribute to the Christmas cactus acquiring a purple hue is rootbound growth. Being rootbound means the plant’s roots have outgrown their current container, inhibiting their ability to absorb nutrients effectively. This can lead to various signs of distress, including purplish discoloration of the leaves.
It is important to note that Christmas cacti thrive when their roots are slightly crowded. Therefore, repotting should only be considered if the plant has been in the same container for an extended period, typically 2-3 years. If you suspect that the purplish leaves are a result of rootbound growth, it is advisable to repot the plant in the spring using a well-drained potting mix. Transferring the Christmas cactus to a slightly larger container will provide the necessary space for the roots to spread, thus facilitating optimal nutrient uptake and potentially alleviating the purple discoloration.
Repotting For Rootbound Christmas Cacti
When a Christmas cactus becomes rootbound, it is essential to take appropriate action to rectify the situation. Repotting offers an opportunity to rejuvenate the plant and ensure its continued health and vibrancy.
To repot a rootbound Christmas cactus, begin by selecting a slightly larger container with good drainage. Spring is the ideal time to undertake this task, as the plant is beginning its growth phase. Carefully remove the cactus from its current container, gently separating the roots if necessary. Ensure that any dead or decaying roots are trimmed before placing the plant in the new container with fresh, well-drained potting mix. Be cautious not to bury the stem too deep, as this can cause moisture retention and promote rotting.
By repotting your rootbound Christmas cactus in the appropriate manner, you provide it with the necessary conditions for healthy growth. The improved nutrient absorption and root development should gradually eliminate the purplish coloration, restoring the plant’s natural beauty.
Excessive Direct Light And Purple Edges
While Christmas cacti thrive in bright indirect light, excessive direct sunlight can cause damage, leading to purple edges on the leaves. This is a sign of sunburn, which occurs when the plant is exposed to intense sunlight for extended periods.
To avoid this issue, it is essential to select an appropriate location for your Christmas cactus. Ensure that it is placed away from open doors, drafty windows, and hot, dry areas. Find a spot with bright, indirect light, such as an east or west-facing window. If necessary, consider using a sheer curtain or indoor shade cloth to filter the sunlight and protect the plant from harmful UV rays.
By providing optimal lighting conditions, you can prevent the purpling of the leaf edges and promote the overall health and vitality of your Christmas cactus.
a Christmas cactus turning purple is a clear indication of an issue that requires attention. Nutritional deficiencies, such as a lack of fertilization or magnesium, rootbound growth, excessive direct light, or a combination of these factors, can contribute to the purplish discoloration of the leaves. By addressing these issues through regular fertilization, Epsom salt feeding, repotting when necessary, and providing appropriate lighting conditions, you can restore your Christmas cactus to its vibrant glory.
