Can I Graft A Moon Cacti Onto A Christmas Cactus?
You’ve nurtured your Christmas cactus for years, admiring its holiday blooms. But its plain green stems seem drab compared to the vibrant colors and fun shapes of moon cacti. What if you could fuse them together for a totally unique plant?
The good news is – you can! Grafting allows joining your Christmas cactus as the hardy rootstock with a moon cactus scion on top. This produces an amazing succulent that combines the best features of both plants. While grafting cacti takes focus and care, the final product is well worth it.
This guide will walk through every step needed to graft a stunning moon cactus onto a Christmas cactus, from picking the perfect plants to providing follow-up care. Let’s get started!

How Do You Choose the Right Moon Cactus for Grafting?
Before starting the process, you must choose a suitable moon cactus. Now it’s time to pick the perfect moon cactus scion to complete your grafted creation! Consider these factors when selecting:
Color
Moon cacti come in a rainbow of hues:
- Red – Rich crimson tones for high contrast
- Yellow – Cheery and bright against green
- Orange – Vibrant citrus color is on trend
- Pink – From pale blush to fuchsia pops
- Purple – Deep eggplant makes a statement
Go with your favorite, or mix multiple!
Shape
Beyond round spheres, explore unique shapes:
- Crested – Ruffled vertical ridges
- Torch – Tall and tapering spines
- Brain – Wrinkled globular form
- Clumping – Clustered balls
- Columnar – Upright cylindrical stems
Shapes impact the silhouette of your finished plant.
Size
Pick a moon cactus in scale with your rootstock:
- 1-2 inches – Best for smaller Christmas cacti
- 2-4 inches – Ideal size range for most grafts
- 5+ inches – For large, mature rootstock plants
Oversized moons stress delicate grafts. Undersized looks unbalanced.
With moon cacti, you’re spoiled for choice. Evaluate graft goals, artistic vision, and plant specs to select your perfect match. Then get ready to create a showstopper fusion!
Steps for Grafting Moon and Christmas Cacti
Grafting a moon cactus onto a Christmas cactus may sound complex, but follow these steps, and you’ll have a unique plant to enjoy for years.
Selecting the Right Plants
Choosing compatible cacti is key to grafting success.
Christmas cactus: Pick a mature, healthy rootstock plant with stems 2 inches or longer. Smaller, younger Christmas cacti don’t have enough vascular tissue to support a graft.
Moon cactus: As mentioned above, opt for a scion that’s disease and pest-free, with its iconic crest shape. Match the moon cactus size to the rootstock – a 2-inch stem can support a 2-inch diameter moon cactus.
Make sure both plants are turgid, not thirsty. Dehydration impedes the grafting process.
Gather Your Materials
These basic supplies make grafting smooth sailing:
- Sharp knife or razor: Sterilize with isopropyl alcohol to prevent disease transmission. A new, unused, single-edge razor works great.
- Cutting surface: Like a smooth ceramic tile or sanitized tray. Avoid wood, which can harbor bacteria.
- Grafting tape: Select breathable, stretchy tape like Parafilm or grafting clip.
- Q-tips, cotton balls: For applying alcohol during sterilization.
- Spray bottle: Misting helps keep cacti turgid.
- Tweezers or tongs (optional): Useful for handling moon cactus.
Preparing the Cacti
Get your plants graft-ready with these tips:
- Wash your hands, tools, and work surface before beginning.
- Mist cacti with water to maximize turgidity.
- Trim any overlapping Christmas cactus segments, leaving 2 inches of bare stem.
- Remove the moon cactus from the soil, handling it gently to avoid bruising.
Now comes the fun part – it’s time to make your cuts!
Cutting the Rootstock
Let’s start with the Christmas cactus:
- Sterilize your cutting tool with an alcohol-soaked cotton ball or Q-tip.
- With a sharp knife, make a 1.5-2 inch inverted V-shaped cut into the stem.
- Angle the knife 45-60° to maximize exposed vascular tissue.
- Keep the cut smooth and clean by slicing in one continuous motion.
Cutting the Scion
- Moving on to the moon cactus:
- Sterilize your cutting tool again.
- Turn the moon cactus upside down in your hand.
- With the knife, make a V-shaped cut into the bottom, matching the rootstock’s cut size.
- Repeat the angled 45-60° slice in one smooth motion.
- Optionally, trim any excess crest material to reduce stress on the graft.
Now, just connect the V’s
Joining the Cuts
This tender join needs protection to fuse correctly:
- Fit the moon cactus’s cut precisely onto the rootstock’s cut.
- The cambium layers should be touched to enable vascular fusion.
- Wrap grafting tape fully around the join, spanning 1 inch above and below.
- Seal the tape against air exposure.
- Tighten and smooth the tape to stabilize the join.
- Mist lightly to moisten the tape and cuts.
Success! Now, it’s time to nurture your creation.
Caring for the Graft
Help your graft thrive with attentive aftercare:
- Move the grafted cactus to a warm, shaded area around 70-80°F.
- Avoid direct sunlight, which can overheat.
- Mist 1-2 times per day to keep the tape and cuts moist.
- Check daily that the tape remains sealed. Reapply if needed.
- After 2-3 weeks, the cuts should fuse, and the tape can be removed!
- Slowly introduce partial sunlight, keeping the soil slightly dry.
Tips for Grafting Success
You’ve prepped your plants and made the delicate graft cuts. Now it’s time to set your new creation up for bonding success. Follow these handy tips:
Optimize Healing Conditions
The right environment helps tender grafts recover:
- As mentioned earlier, Keep temps 70-80°F – growth slows in cool weather.
- High humidity prevents drying. Mist graft 1-2x daily.
- Bright shade avoids sun scorching.
- Air circulation via a fan ward off fungal issues.
- Monitor for pests like mealybugs who attack weakened plants.
Choose the Best Time
Graft in the seasons when cacti are most active:
- Spring is ideal as temperatures rise and light levels increase.
- Fall works, too, before cacti enter winter dormancy.
- Avoid grafting in winter or summer when growth stalls.
- Plan 1-2 weeks of undisturbed healing before seasonal changes hit.
Be Patient!
Grafting takes time and care. Don’t get discouraged by:
- Slow growth – the grafted plant pauses to heal.
- Leaf drop – some die-off is normal post-grafting.
- Shape changes – compressed crest? Give it time to adjust.
- Color loss – hues often return after several months.
With attentive care and optimism, you’ll be rewarded with a stunning grafted cactus!
Long-Term Care of Grafted Cacti
Congrats, your grafted cactus is established and thriving! But don’t neglect those specialized care needs as your plant matures. Here’s how to keep it healthy long-term:
Yearly Maintenance
Perform annual grooming:
- Inspect for pests like mealybugs that can attack in crevices.
- Trim any dead or damaged stems back to healthy tissue.
- Pinch off excess growth to maintain the graft union.
- Check that the graft remains sturdy.
- Clean accumulated dust on leaves for maximum sun absorption.
Smart Repotting
Re-pot every 2-3 years:
- Choose a pot 1-2 inches larger than the current one.
- Use cactus soil mixed with 50% inorganic grit like perlite or pumice.
- Don’t disturb the sensitive grafted roots.
- • Position so the graft stays above the soil line.
Tailored Care
Tweak conditions for grafted needs:
- Let the soil dry between waterings, but don’t let it get bone dry.
- Humidify with pebble trays to prevent shriveled leaves.
- Rotate plants to distribute light and encourage even growth.
- Fertilize monthly during growth seasons with half-strength cactus feed.
Treat your creation with care, and you’ll enjoy its unique fusion for years to come!

Frequently Asked Questions
Do grafting questions? Here are answers to some common queries:
Why Graft Cacti?
Grafting allows combining the best features of two cacti into one plant. Take the hardy roots of a Christmas cactus and fuse them with the colorful crest of a moon cactus for a unique succulent.
What Cacti Can Be Grafted Together?
Many cactus varieties are graft-compatible. Common combinations include moon cactus scions grafted onto dragon fruit, Peruvian apple cactus, or Christmas cactus rootstocks.
How Long Does a Cacti Graft Take to Heal?
Plan on 2-3 weeks for the graft union to fuse. Grafted cacti need another 1-2 months of adjusted care as they fully recover. Monitor the area where the two plants join until you see obvious tissue fusion.
Do Grafted Cacti Live As Long As Ungrafted Plants?
With proper care, grafted cacti can thrive just as long as their ungrafted cousins. Tend to their specialized needs like humidity and light levels, and your creation can last years.
