What to expect in the box
You will receive the exact Stenocereus griseus cutting pictured, unrooted and callused, shipped without soil or a pot. After arrival: unbox with thick gloves, the spines are long and sharp. The cut end is already callused. Stand it upright in dry, fast-draining cactus mix (bury the bottom 3-4 inches and stake it if needed) in bright shade. Do not water for 2-3 weeks, then water lightly and let it dry fully between waterings. Move it into full sun once it resists a gentle tug, usually within 6-10 weeks in warm weather. Some scuffing of spines in transit is normal and does not harm the plant.

Cacti can look slightly dull after a few days in a dark box. Color returns within a week or two of bright light. If your area drops below 40F, we recommend adding a heat pack to your order, as one is not automatically included.

How to root your cutting

1. Let it callous. Keep the cutting upright in a dry, shaded spot for 2 to 3 weeks so the base fully hardens. Do not water it during this time.

2. Plant it. Set the calloused end 1 to 2 inches deep in dry, well-draining cactus soil. A terracotta pot with a drainage hole works best.

3. Wait, then water lightly. Hold off on water for about a week after planting, then water sparingly until roots take hold. Start it in bright, indirect light and move to full sun over a few weeks.

This is the exact plant you will receive. A one of a kind Stenocereus griseus cutting, the Pitayo de Mayo, a straight single column about 36 inches tall and 4 inches across, taken from a mature plant with a corky trunk. Rounded ribs carry evenly spaced white areoles, each with a neat star of silver spines, over fresh bright green skin. The cut end is callused and ready to root.

Pitayo de Mayo is a fruit cactus from Mexico, Colombia and Venezuela that grows into a tall candelabra tree and is farmed for its sweet pitaya fruit. It is fast for a columnar cactus, and a cutting this size roots into a big plant quickly.

Stand it in dry, fast-draining mix in bright shade, hold off on water for two to three weeks, then move it into full sun once it has taken hold.

  • Light: Full sun once rooted
  • Water: Low. None until rooted, then soak and dry, minimal in winter
  • Hardiness: USDA zones 9 to 11, protect from hard freezes
  • Growth: Fast columnar tree, branching with age

Please note: This is an unrooted, callused cutting shipped without soil or a pot. You will receive the exact cutting pictured.

Cold Weather Warning

If your area drops below 40°F during the colder months, we highly recommend adding a heat pack to your order, as we don’t automatically include one. This helps keep your plants safe in transit. 🌡️❄️

Product Details

Cactus Care

Stenocereus griseus is a sun-loving fruit cactus from Mexico and northern South America. Root the cutting first, then treat it like an organ pipe: heat, light and sharp drainage.

  • Light: Bright shade while rooting, then full sun. At least six hours of direct sun keeps the column tight.
  • Water: Nothing for the first 2-3 weeks. Once rooted, soak and dry: water deeply, then let the soil dry completely. Nearly dry in winter.
  • Soil: Sandy, fast-draining cactus mix or a gravelly, well-drained landscape bed.
  • Temperature: Hardy in USDA zones 9 to 11. Tolerates brief light frost when dry; protect below about 25 F.
  • Feeding: None until rooted. Then a diluted cactus fertilizer once or twice in spring and summer is plenty.
