How to Move a Barrel Cactus

Mark one side of the barrel cactus by tying a string around and making a bow on the side that faces the afternoon sun. This will help you orient the cactus in the same position in its new location.

Dig carefully 6 to 12 inches out from the plant to loosen and remove as many roots as possible. Take care not to damage the roots, as cactus roots are fragile, and most are close to the surface. Work your shovel under the plant and carefully pry it out of the ground.

Wrap a garden hose around the plant, slightly below the middle, and lift the cactus out of the hole. This may take two people.

Lay the plant on its side carefully and cut off any damaged roots to avoid pathogens entering the plant. Do not cut off healthy roots.

Place the cactus in the shade or cover it with shade cloth and allow the roots to dry for at least three days.

Pad a hand truck with a thick piece of foam rubber or blankets. Carefully place the barrel cactus on the hand truck, taking care not to damage the ribs or spines. Move the plant to its desired location.

Dig a shallow hole wide enough for the cactus roots. Add 25 percent compost to sandy soil. Add 25 percent perlite to clay soil to ensure good drainage.

Place the barrel cactus in the hole and use the garden hose to align it to its original position. This is essential to keep the cactus from being sunburned.

Backfill the hole and use the shovel handle to tamp the soil in around the roots to eliminate air pockets. Water the cactus thoroughly.

Cover your barrel cactus with shade cloth until growth resumes. Shade cloth is not needed if the cactus is transplanted in early spring or late fall.

Water the barrel cactus twice a week while it is getting established, but only if the nighttime temperatures are above 60 degrees F. Do not water cactus at temperatures under 60 F unless there is no rain for two to four weeks.
