Seven critical comparisons that show you exactly what healthy propagation looks like versus the early warning signs of failure. Learn to read the signs before it's too late.
Move the slider to reveal what healthy propagation looks like versus what happens when things go wrong.
Every aspect of propagation has a tipping point between success and failure. Here's what to look for.
| Aspect | Success | Failure | Why It Fails |
|---|---|---|---|
| 1. The Break | Clean smooth "pop" leaving a concave "U" shape | Ragged tear or leaf snapped in half | If the growth point (meristem) stays on the stem, the leaf cannot produce a pup |
| 2. Callusing | Wound is dry, firm, tan/white like a scab | Wound is black, mushy, translucent, or fuzzy | Rot from high-humidity area or damp soil too soon |
| 3. Light Level | New growth is compact, tightly clustered, natural color | Plant is "leggy" (stretched), pale, leaning | Etiolation - starving for light, burning energy to find it |
| 4. Sun Exposure | Mother leaf stays plump and green/blue for weeks | Mother leaf turns brown, crispy, white "bleach" spots | Scorching - UV too high for a rootless plant |
| 5. Watering | Tiny pink or white "hairy" roots dive downward | Roots turn brown, shrivel, or base becomes black slime | Over-hydration - watered before roots existed |
| 6. Soil Choice | Water disappears instantly, dries in 2–3 days | Water pools on top, pot stays heavy/damp for a week | Suffocation - standard soil lacks oxygen for roots |
| 7. Mother Leaf | Original leaf slowly shrivels into dry husk after baby is 1/2 inch | Original leaf turns yellow, falls off, or rots while baby is tiny | Resource exhaustion from extreme heat or lack of indirect light |
These mistakes are subtle, but they account for the majority of failed propagations. They don't show up in the matrix above because they're about what you do, not what you see.
Misting doesn't encourage roots. Roots grow searching for water. Always-damp soil removes the motivation for deep root development and creates the perfect environment for rot.
A tiny cutting in a giant pot means the soil stays wet too long. Small plants need small containers. The soil in a large pot takes much longer to dry, keeping roots in damp conditions that promote rot.
In Quebec winters and other cold regions, stagnant indoor air lets fungal spores settle on callused wounds. Even healthy callus can rot in a sealed environment.
Now that you know what success and failure look like, learn the biology behind each stage.
