Cylindropuntia imbricata, the cane cholla (or walking stick cholla, tree cholla, chainlink cactus, etc.), is a cactus found in the Southwestern United States and northern Mexico, including some cooler regions in comparison to many other cacti. It occurs primarily in the arid regions of the Southwestern United States in the states of Kansas, Oklahoma, Texas, New Mexico, Arizona, Colorado, and Nevada. It is often conspicuous because of its shrubby or even tree-like size, its silhouette, and its long-lasting yellowish fruits.
Tree cholla shows strong resistance to diseases and generally copes well under typical care without becoming ill easily. That said, it can be vulnerable to mealybugs; these pests may cause some harm but are usually not a major danger. Regarding care, Tree cholla is tolerant of drought and does not need frequent watering. It can endure extended stretches without water and requires minimal fertilization. However, if it receives poor light and is watered too much, it becomes very prone to root rot. In summary, Tree cholla is a good choice for people who prefer low-maintenance plants, though it’s important to meet its basic needs. It is especially appropriate for those who are away for long periods and might forget to water regularly.
How to keep Cylindropuntia Imbricata.
Light
The tree cholla thrives beneath an unobstructed clear sky, receiving abundant light. It tolerates partial shade and can withstand diffused sunlight. Still, plentiful light encourages healthy, vigorous growth, particularly during important growth stages. Native to sunny habitats, the tree cholla can be harmed by insufficient light or by too much light, which may lead to sunscorch.
Water
Tree cholla is native to arid regions, where it thrives with minimal water and low humidity. It should be watered every four weeks. This plant usually grows outdoors in full sun and well-draining soil, demonstrating its ability to withstand drought and adapt to dry climates.
Humidity
This plant prefers dry conditions, so don't mist it. However, watering it less often can also thrive in higher humidity.
Temperature
Tree cholla prospers in areas similar to its native habitat, needing temperatures between 59 and 100 °F (15 and 38 °C). In cooler seasons it can tolerate brief cold spells but should be protected from prolonged cold.
Fertilizer
For Tree cholla, small amounts of fertilizer applied one to two times a year during the growing season are sufficient. Avoid fertilizing in winter and in summer when the plant is dormant. Reduce fertilizer for repotted plants and wait a couple of months after repotting before fertilizing. Fertilizing supports healthy growth and encourages blooms.
Pruning
Tree cholla requires minimal pruning. Simply remove dead flowers and branches to help the plant direct nutrients toward healthy growth.
Pot & Repot
Tree cholla is a sturdy cactus that can grow up to 15 feet (4.6 meters) tall. It's best to rehome it every 2-3 years. Repot the cactus in late spring, choosing a container that is slightly larger than the root ball and offers good drainage. After repotting, wait a week before watering, and then continue with a light watering schedule.

Reader questions.
What's the best way to water my Tree cholla?
- Water the plant from the bottom to ensure proper absorption of water by the roots and circulation of nutrients from the soil throughout the plant's body. Avoid spilling water on the top part, as this can lead to diseases and fungi. - If you have irrigation systems, use small sprinklers for watering Tree cholla in your garden. Opt for revolving sprinklers that allow you to adjust the water delivery patterns as needed. Avoid using sprinklers on windy days. - Regardless of whether the Tree cholla is in a pot or in your garden, it is best to use the soak and dry method for watering. This method evenly distributes moisture across the root systems, promoting healthier growth. - Some owners may consider installing a built-in drainage system for their succulents. This involves placing layers of porous materials such as recycled glass or hydro stones beneath the soil. These materials serve as reservoirs for excess water, so it's important not to overwater and flood these built-in systems.
Why do I have to put fertilizer on my Tree cholla?
Fertilizing Tree cholla is important for adding nutrients to the growing medium. While it already stores water and nutrients, applying plant food during the growing season aids in supporting healthy growth. Additionally, fertilizing can stimulate mature Tree cholla to produce blooms in the growing season.
What are the sunlight requirements for Tree Cholla?
Tree Cholla requires full sun exposure of above 6 hours of sunlight daily to thrive effectively. It can also tolerate partial sun, with about 3-6 hours of sunlight. It's crucial to observe the movement of sunlight through your garden to find spots offering the perfect balance of light and shade for your plants, ensuring their well-being. The optimal light environment stimulates healthy growth, especially during critical growth stages, as Tree Cholla originates from sun-abundant habitats. However, insufficient light or excessive exposure can cause issues like inadequate growth or potential sunscorch.
What are the ideal growing conditions for Tree Cholla?
Tree cholla thrives in warm environments and requires higher temperatures during its growing season to foster growth and metabolism. This plant loves to bathe in ample sunlight, benefits from appropriate moisture levels, and needs good ventilation to thrive. It is, however, vulnerable to damage from excessively low temperatures and overwatering. Therefore, maintaining a balance is crucial; avoid overly high temperatures and excessively dry conditions. Additionally, tree cholla is a heat-loving plant that enters a dormant state in winter. When temperatures drop below -10°C, it's advisable to move it indoors and place it near a south-facing window to ensure it receives as much sunlight as possible. Supplemental lighting may be necessary if natural light is insufficient. Below 15°C, the plant's growth slows, and watering should be reduced or ceased to avoid root rot. Outdoor tree cholla should not be watered during cold temperatures, and if possible, consider using a temporary greenhouse for insulation or wrapping the plant with plastic film or fabric to protect it from the cold.
What should I do if I give my Tree cholla plant too much or too little water?
If you notice that the Tree cholla is turning yellow, it could be due to either underwatering or overwatering. Overwatering can lead to fungal infections, so it's important to let everything dry out and avoid overwatering. Similarly, if your plant is browning and dropping, this suggests that it's getting too much water. On the other hand, if there's not enough water, you may see yellow tips forming on the stems and branches. When purchasing a Tree cholla, it's a good idea to ask about the soil drainage. If the topsoil doesn't drain properly, the plant may not receive enough water in the future. Additionally, excessive watering and too much rain can cause the Tree cholla to die. For watering, it's best to use rainwater or distilled water as the plants don't tolerate minerals well. If you observe squishy stems, drooping growth, or discolored parts, these are all signs of excessive moisture. Give the plant time to recover by allowing the pot to dry out. If it's planted outside, you can transfer it to a pot, especially during winter, to aid in its recovery and prevent root rot.
When should I fertilize my Tree cholla plant?
Tree cholla, like other plants, benefits from nutrients, but it only requires a small amount of fertilizer during the growing season. It is recommended to fertilize the Tree cholla 1-2 times a year, specifically in the spring and autumn, avoiding the dormant periods in winter and summer. When repotting the plant, be cautious and reduce the amount of fertilizer used. It is also advisable to wait a couple of months after repotting before beginning to apply fertilizer.
How does artificial lighting benefit Tree Cholla?
Artificial lighting is beneficial for indoor Tree Cholla plants, especially when natural sunlight is limited, such as during winter or in less sunny indoor spaces. It promotes faster, healthier growth by providing adequate lighting, crucial for optimal plant development. Selecting the right type of artificial light, such as LED lights, is important because they can be tailored to provide specific wavelengths needed by your plants. Full-sun plants require 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants require 10-20W/sq ft. The light source should be placed 12-36 inches above the plant to mimic natural sunlight, and the duration should match the natural daylight hours, generally 8-12 hours per day.
How does Tree Cholla respond to low temperature and what are the solutions?
Tree cholla is best suited to high temperatures and does not tolerate low temperatures well. It grows optimally when the temperature is above 15°C and should be kept above -10°C during winter. Exposure to temperatures below -15°C may result in the plant becoming weak, wilting, and being prone to root rot. Mild frost damage might not show immediate symptoms, but the plant will gradually wither within a week. To address frost damage, trim the frostbitten areas, focusing on whether there's root rot. In cases where the roots have rotted, they should be cut off, and the plant can be propagated through cuttings. It's crucial to move the plant indoors to a warm environment promptly and place it near a south-facing window to ensure it receives ample sunlight. If natural light is insufficient, supplemental lighting can help.
How frequently should I water my Tree cholla?
Watering frequency for succulents can vary depending on the season. In the summer and spring, you typically only need to water them once every two to three weeks. However, during the winter and fall, it's best to reduce or avoid watering altogether since these plants become dormant. It's important to let the soil dry completely before watering again. It's better to slightly underwater than to overwater. When potted, deep watering at intervals promotes healthier soil growth. When planted outdoors, avoid watering lightly as this encourages shallow root growth. Instead, wait a few weeks and only water when the surrounding soil is too dry.
When is the best time to not fertilize my Tree cholla?
Tree cholla, like other plants, goes through a dormancy period. During this time, it's best to avoid applying fertilizer. The plant stops growing in both summer and winter, so it's recommended to refrain from fertilizing during these seasons. Additionally, it's advisable to hold off on fertilizing for the first few months after repotting in the spring.
What are symptoms of improper lighting in Tree Cholla?
Tree Cholla may exhibit various symptoms under suboptimal lighting conditions, including smaller new leaves, leggy or sparse growth, faster leaf drop, slower or halted growth, lighter-colored new leaves, chlorosis, sunscald, leaf curling, wilting, and leaf scorching. These symptoms range from growth deficiencies, such as stretched-out appearance and early shedding of leaves due to conservation of resources, to physical damage caused by excessive sunlight, like sunscald and leaf scorching. Monitoring for these symptoms is critical to maintaining the health and development of Tree Cholla.
What should be done if Tree Cholla is exposed to temperatures above its tolerance?
Tree cholla should ideally be kept under 38°C during summer. When the temperature goes above 43°C, the plant's growth halts, experiences water loss, wilting, and becomes more prone to sunburn. In cases of sunburn or root rot, remove the affected parts. Protect the plant from the intense afternoon sun until it recovers and resumes growth. For plants suffering from root rot, cease watering until new roots start to grow, indicating recovery.
