Occasionally, mature cactus plants have to be moved. Moving cacti in the landscape, especially large specimens, can be a challenge. This process poses more danger to you than the plant due to the spines, thorns and other dangerous armor most of these plants possess. Transplanting a cactus can be done at any time of the year, but the best time is in cool weather. Some tips on how to transplant a cactus without harm to you or the plant will follow.
Before Moving Cacti in the Landscape
Mature cactus plants can get quite large and require professional assistance to minimize plant damage. If you are determined to take on the process yourself, consider site preparation, have several extra hands available and prepare the plant carefully to avoid harming pads, limbs and causing yourself and your helpers any pain.
Only transplant healthy specimens that will have the best chance of re-establishing. A word of caution: wild cactus cannot be harvested legally in most areas, so this information applies to cultivated cacti in the landscape only.
Preparation is crucial when moving a cactus plant. Mark the plant so you can situate it in the same orientation in which it is growing. Plants with large pads should be swaddled in an old blanket or something that will cushion the limbs while giving you protection from the spines.
How to Transplant a Cactus
Begin by digging a trench around the plant 1 to 2 feet away and about 18 inches deep. Then start prying around the plant gently. Cactus roots are usually near the surface but are delicate, so be careful during this process. Once you have excavated the roots, use the shovel to pry out the plant. Wrap a large garden hose around the plant and lift it out of the hole. If the plant is large, you may need more than two people, or even a vehicle for pulling.
Successfully transplanting a cactus requires careful new site preparation. The cactus roots should air dry for a few days before installing the plant in its new location. During this time, assess the soil and amend as needed. In sandy locations, add 25% compost. In areas with rich or clay soil, add pumice to help assist with drainage.
Dig a shallow, wide hole that is the same size as the original planting site. Orient the cactus at the same exposure it experienced in the old planting location. This is one of the more crucial details because it will prevent or minimize sunburn. Carefully lift the plant and settle it in the correct orientation in the prepared hole. Backfill around the roots and tamp down. Water the plant deeply to settle the soil.
Some special care is required for several months after moving a cactus plant. Water the plant twice per week for a month unless nighttime temperatures drop below 60 degrees Fahrenheit (16 C.). In this case, do not water unless up to 4 months have gone by without precipitation.
If transplant takes place in spring or summer, cover the plant with shade cloth to prevent burning. Keep the cloth in place for 3 to 4 weeks as the plant re-establishes and adapts to its new conditions.
Large plants over 5 feet in height will benefit from staking. After a month, diminish watering frequency to every 2 to 3 weeks in summer and 2 to 3 times during winter. Watch for signs of stress and address each symptom individually. Within a few months, your plant should be well established and on its way to recovery from the moving process.
