How to Begin Cactus Raising

Cacti appeal to many gardeners in arid and semiarid climates around the world, both for their resistance to drought conditions, and the great diversity of unusual and ornamental forms they take. Like most succulents, cacti grow easily from cuttings and are among the easiest plants to raise, making them a suitable starter plant for novice gardeners. The basic steps for growing cactus are the same regardless of the species, and although it takes few tools or materials to accomplish, the cacti must be provided with constant warmth and strong light during the rooting process.

Instructions

- 1
  Take a cutting from a healthy, mature cactus in early summer. Select a cutting based on the type of cactus it is. Choose a 4- to 6-inch-long portion from a column-type cactus such as saguaro or golden column cactus, and one whole paddle from a pad-type cactus such as opuntia.
- 2
  Sever the cutting using a utility knife. Make the cut straight across. For paddle-type cactus, sever the cutting at the joint between the pads.
- 3
  Store the cactus cutting in a warm, dry place with good air circulation and bright light for one to two weeks, or until the severed end of the cutting has dried out and is beginning to form roots.
- 4
  Choose a plastic nursery container large enough to provide 1 inch of space around all sides of the cutting. Fill the plastic nursery container with a mix of 4 parts sharp river sand, 1 part compost and 1 part perlite. Moisten the growing mix with 1/2 cup of water.
- 5
  Nestle the cactus cutting in the pot of growing medium. Bury the cactus cutting to half its height. For paddle-type cacti, mound growing medium on both sides of the cutting to hold it upright.
- 6
  Place the potted cactus cutting near a source of very strong, bright light. Keep the potted cactus cutting on a warming mat set to 80 degrees Fahrenheit. Pour 3 or 4 tbsp. water around the cutting every four days.
- 7
  Check for root growth in three to four weeks by gently grasping the cutting with a pair of tongs and tugging on it. Repot the cactus cutting once it grows roots and shows significant plumping in the flesh or bright green coloration near the tip.
