How to grow Cactus from cuttings – propagating cactus – roots and planting

Propagating cacti is very easy.  First gather the cactus cuttings from the parent plants.    Make sure your knife is clean and sharp before cutting your cactus.  For paddle cacti a single pad makes a good cutting.

For branching cacti, be sure the cutting is taken from a joint on the mother plant. Cutting on a diagonal angle is beneficial to the mother cactus so water doesn’t pool on the healed cut.  Never handle a cactus with your hands.

To grow a successful cactus you MUST let the fresh cutting callus over and heal.  Place them in a dry, warm place for up to 2 weeks.  The larger the cut surface is, the longer it needs to dry.  This may sound extreme but remember cactus are drought tolerant.  If you choose to use a rooting hormone make sure it is powder!  Do not let your cactus cuttings get moist or wet.

It is easiest for your cactus cuttings to root during warm weather.  According to the University of Arizona, the best time to propagate your cacti is during August & September when the soil temperatures are warm and conducive to rooting.  Some shade is best for rooting and will prevent your cactus cuttings from sunburn.

Pick a good container with drainage holes for your callused cactus cutting.

When planting your cactus use a well drained soil mixture designed specifically for cacti. Plant the cutting about 2 inches deep and pack the soil around the cactus.  I also use small rocks to help keep the cuttings from falling over.  Wait about 2 weeks to water; then soak the cactus well and let it dry out another 2 weeks.   The biggest problem for growing cactus is over-watering.   Too much water causes the roots to rot.

Cactus are dormant during winter.  Do not water a cactus during cold weather unless it looks shriveled.

Giant Saguaro desert cactus – facts and photos

Within Arizona’s Tucson Basin is The Saguaro National Park.  This park provides the ideal conditions for sustaining dense stands of the famous saguaro cactus.

**The most important factors for growth are water and temperature. If the elevation is too high, the cold weather and frost can kill the saguaro. Although the Sonoran Desert experiences both winter and summer rains, studies show that the Saguaro cactus obtains most of its moisture during the summer monsoon season.

There are dozens of varieties of cacti;  short, tall, stout, delicate but none quite as magnificent as the Giant Saguaro cactus.

Quick Saguaro Facts:

  1. Saguaros have one deep tap-root but most of this cactus’ roots are 4-6 inches deep and span out as far as the desert plant is tall.
  2. The saguaro is the largest cactus in the US.
  3. After the saguaro dies its woody ribs can be used to build roofs, fences, and parts of furniture.
  4. The Giant Saguaro can live to be 200 years old.

In the Sonoran desert the saguaro cactus has a boundless variety of towering and many armed shapes.

Water makes up 75 to 95 percent of the saguaro cactus’ weight.  During periods of drought the pleats of the saguaro cactus contract.  During Arizona rains the saguaro expands as it soaks up moisture.

Saguaros, like many desert cacti, grow excruciatingly slow.  Arizona cactus experts estimate that a forty-foot tall saguaro is about 150 years old.  Arm buds begin to appear when the saguaro is 75 years old.

Many saguaros now standing in cactus forests germinated in the mid-1800s.

To survive their early years, saguaro seedlings must be sheltered from the elements, whether it be under the canopy of other plants or in the crevices of rocky outcrops. Saguaro seeds can be deposited in droppings of birds roosting on branches of shrubs and trees.

Lightning, powerful winds, harsh winter freezes and the rotting of dead tissue kill saguaros.  The saguaro’s woody ribs stay on the desert floor until they are consumed by termites or decay and return to the soil.

The saguaro is not currently listed as threatened or endangered. Arizona has strict regulations about the harvesting, collection or destruction of the saguaro cactus.

Saguaro cactus can be found in southern Arizona and western Sonora, Mexico.
