Introducing the stunning White Ghost Cactus, also known as Euphorbia lactea variegata, a vibrant cultivar of Euphorbia lactea. While Euphorbia lactea White Ghost is commonly referred to as the "White Ghost Cactus," it's actually not a true cactus. It's a succulent shrub or a small tree from the Euphorbiaceae family. The name "White Ghost" is given to it because of its pale white color and ghostly appearance. So, even though it's not a cactus, it's still called a "cactus" because of its cactus-like shape and the way it's often grouped with other succulent cacti. 

With the thick, fleshy triangular stems of the white ghost cacti, Euphorbia grow upright and branch out as they mature. The stems are variegated with shades of white, green, and sometimes even pink or yellow. Instead of leaves, it has small, spiky thorns or spines along the edges of its stems. These thorns are not only decorative but also serve as a defense mechanism against predators. 

Native to the tropical regions of Africa and Asia, with a slow growth rate, the Euphorbia lactea White Ghost cactus can grow up to 6 feet tall in its natural habitat. However, when grown as a houseplant, it tends to stay smaller, usually reaching heights of about 1 to 3 feet. Its size can also be controlled through pruning and proper care. 

The flowers of the white ghost cacti bloom in the spring season with yellow-white or greenish-yellow hues. These flowers may not be as showy as those of other plants, but they have their own charm. The blooms are surrounded by colorful bracts, which are modified leaves that often have a variegated pattern of white, green, and sometimes pink. Together, the flowers and braces create an interesting and eye-catching display. 

Additionally, the Euphorbia lactea 'White Ghost' is mildly toxic to both humans and pets with poisonous sap and should be kept away from children and pets because of its potential skin or eye irritation. 

Watering Needs 

Like other succulents, the White Ghost Euphorbia lactea has specific watering requirements. It is adapted to survive in arid conditions, so it prefers infrequent watering. To keep your White Ghost cacti happy and healthy, it's best to water it sparingly. In between waterings, let the soil dry out completely. This means waiting until the soil is dry to the touch before giving it a good drink. Overwatering can be detrimental to your Euphorbia lactea White ghost, as it is prone to root rot. 

During the growing season, which is typically in the spring and summer, Euphorbia lactea variegata needs watering once every 2-3 weeks. The soak-and-dry method is the best technique to develop this plant. However, it's important to adjust the watering frequency based on the environmental conditions and the moisture level of the soil. In hot and dry climates, you may need to water it more often, while in cooler and more humid conditions, less frequent watering may be required. 

During the winter months, when the cactus is in its dormant period, you should reduce the watering even further. It's best to water sparingly, only when the soil is completely dry. This helps prevent the risk of overwatering and allows the cactus to rest during its dormant phase.

Remember, it's always better to underwater than to overwater the White Ghost. This resilient succulent plant can tolerate periods of drought, but it does not tolerate excessive moisture well. So, be sure to observe the soil moisture and adjust your watering schedule accordingly. 

 Light Requirements

When it comes to growing the White Ghost Cactus indoors, it thrives in bright, indirect light. Place this potted plant near a window that receives plenty of sunlight throughout the day. However, be cautious of placing it in direct sunlight, especially during the intense afternoon sun, as it can scorch the delicate succulent. If you notice your white ghost succulent stretching or becoming pale, it may be an indication that it needs more light. In that case, you can consider supplementing its light with a grow light to ensure it gets the necessary brightness.

If you are growing the White Ghost plant outdoors, this Euphorbia lactea variegata needs full to partial sun, which helps the plant grow properly. It can tolerate and even enjoy direct sunlight for several hours a day. Find a location in your garden or on your patio that gets at least 6 hours of direct sunlight.  Just make sure to acclimate your Euphorbia white ghost gradually to the outdoor conditions if it has been indoors for an extended period. Start by placing your Euphorbia ghost cacti in a partially shaded area and gradually expose it to more sunlight over a few weeks. 

Remember, whether indoors or outdoors, the White Ghost appreciates bright light, but it's crucial to protect it from scorching sun rays. By providing the right amount of light, you'll help your White Ghost Euphorbia thrive and showcase its stunning ghostly appearance. 

Optimal Soil & Fertilizer Needs 

When it comes to the soil, the White Ghost plants need well-drained soil. You can create a suitable soil mix by combining equal parts of succulent potting mix, perlite, and coarse sand. This blend allows excess water to drain away, preventing the roots from sitting in soggy soil, which can lead to rot. Planet Desert specializes in succulents and has specialized succulent potting soil that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system to help your white ghost Euphorbia succulents thrive. As an okay alternative, you can create your own potting mix by combining equal portions of perlite, coarse sand, and good natural potting soil.

As for fertilizing, the white ghost cacti Euphorbia lactea variegata doesn’t require frequent feeding. During the growing season, which is typically in spring, you can fertilize your ghost cactus once a year. Choose a balanced (5-10-5), water-soluble NPK fertilizer specifically formulated for succulents. Follow the instructions for dilution and apply the fertilizer to damp soil to avoid any potential root burn. During the dormant period in winter, it's best to avoid fertilizing altogether. 

Hardiness Zone & More

If you are growing your white ghost cactus indoors, it thrives in temperatures ranging from 60°F to 80°F. It's important to keep your Euphorbia lactea variegata away from drafts or sudden temperature fluctuations, as it prefers a stable and consistent climate. So, find a cozy spot in your home where the temperature remains within this range, and your white ghost will be happy. 

If you're growing the White Ghost plant outdoors, it is typically suited for USDA zones 9 to 11. These zones generally have milder climates with frost-free winters and warm summers. If you live in a region with colder temperatures, it's best to keep the succulent indoors or provide protection during winter months to prevent any damage from freezing temperatures. 

In terms of humidity, the White Ghost cactus can tolerate a wide range of humidity levels. It can adapt to both dry and slightly more humid conditions. However, it's important to avoid excessive humidity, as it can increase the risk of fungal diseases. Aim for a moderate humidity level, around 40% to 60%, to create a comfortable environment for your ghost cacti.

Propagating White Ghost Cactus 

To propagate the White Ghost Cactus, you can do it by stem cuttings. Select a healthy, mature stem from the parent plant, cut it just below a node, and allow it to dry and callus for a few days. Prepare a well-draining potting mix, either formulated for cacti and succulents or a combination of regular potting soil and perlite. Insert the cut end into the hole, burying the node in the soil. 

Place the container in a warm, bright location, but avoid direct sunlight. Keep the soil lightly moist but not overly wet to prevent rot. After a few weeks, roots should form from the buried node, and the new plant should be treated as a mature White Ghost Euphorbia lactea variegata. The best season to propagate this variety of Euphorbia is the spring season.  

White Ghost Cactus can also be propagated by collecting seeds from mature plants and sowing them in a well-draining soil mix. Proper moisture and light conditions are crucial for germination, and patience is essential as it may take weeks or months. 

Propagation is a rewarding way to expand your Euphorbia lactea White Ghost collection, but patience and proper conditions are essential.
