Almost every “is my plant okay” question in the first few weeks after an aroid arrives comes down to telling these three things apart. They can look similar at a glance — droopy leaves, a yellowing spot, something that seems “off” — but they call for completely different responses. Watering more because you assumed shipping stress when it’s actually root rot makes things worse. Isolating and treating for pests when it’s really just transit stress wastes energy but at least doesn’t harm the plant — which is part of why, when in doubt, the safer guess is usually stress, not catastrophe.
The Short Version
- Shipping stress shows up fast, mostly in the leaves, and gets better on its own within one to two weeks.
- Root rot is often invisible until you actually check the roots — the leaves lag behind what’s happening underground.
- Pests announce themselves with the pests themselves (or their residue), not just symptoms — if you can’t find webbing, stippling, or actual insects, it probably isn’t pests yet.
What to Look At, in Order
- Leaves first — general appearance, which leaves are affected (oldest vs. newest), and whether the change is spreading or holding steady.
- Stem and crown next — where the leaves meet the base of the plant. This is where rot shows up early and clearly, before it’s obvious anywhere else.
- Roots and medium last — this requires gently unpotting, so it’s the last check, not the first, and usually only necessary if the first two steps don’t explain what you’re seeing.
Shipping Stress — What It Actually Looks Like
Timing: appears within the first few days of arrival, generally improves on its own by the one to two week mark.
Leaves: general droop across the plant, maybe one older leaf yellowing or curling. Rarely more than one or two leaves affected at once.
Stem/crown: firm, no discoloration, no soft spots.
Roots: look and feel normal when checked — firm, light in color.
Smell: none.
What to do: nothing, beyond keeping conditions stable. This resolves with time, not intervention.
Root Rot — What It Actually Looks Like
Timing: often not obvious until the roots are checked directly — by the time leaves clearly show it, the rot has usually been developing for a while.
Leaves: yellowing that spreads rather than staying isolated to one leaf, sometimes starting at the base of the plant and working upward. In advanced cases, leaves may go from yellow to mushy rather than crisping and dropping the way a naturally aging leaf does.
Stem/crown: soft, discolored, sometimes dark or black near the soil line — this is often the clearest early tell, faster to spot than the roots themselves.
Roots: dark, mushy, hollow-feeling, falling apart when handled rather than resisting gentle pressure.
Smell: a sour, rotten smell is common in more advanced cases — absence of smell doesn’t rule out early rot.
What to do: trim affected tissue with clean, sharp scissors, let cuts air-dry briefly, repot into fresh, well-draining medium, and reduce watering while the plant recovers.
A genus-specific note on how much damage is survivable: how much root loss a plant can recover from varies a lot by genus. Alocasia in particular store significant energy and water reserves in their corm — the thick, bulb-like base — which means an Alocasia can often survive root damage that would be much more serious for a Philodendron or Monstera, which don’t have that same reserve to fall back on. When in doubt on a non-Alocasia genus, treat root loss more conservatively.
Pests — What It Actually Looks Like
Timing: can appear at any point, not just right after shipping — an infestation that arrived as eggs or juveniles can take a couple of weeks to become visible.
Leaves: stippling (tiny pale dots), sticky residue (honeydew), fine webbing, or distorted new growth. Unlike shipping stress or rot, the leaf symptoms alone are often a strong clue, especially webbing.
Stem/crown: usually unaffected unless the infestation is severe or has been present for a long time.
Roots: usually normal, with the exception of a few soil-dwelling pests (fungus gnats, root mealybugs) that live in the medium rather than on the plant itself.
Smell: none, unless a severe infestation has caused enough damage to invite secondary rot.
What to do: isolate the plant immediately from anything else you own, identify what you’re dealing with before treating (different pests need different treatments), and don’t assume one treatment covers everything. Our own plants are cleaned and treated before they ship to us. Once a plant is in a home environment, mealybugs are one of the most common indoor houseplant pests generally, and especially pervasive in Southern California — what’s most common will vary depending on where you live, so treat this as a starting point rather than an exhaustive list.
When More Than One Thing Is Happening at Once
These three aren’t always separate events. A plant that’s stressed from shipping is also a plant with lowered resistance, which is exactly when a marginal pest population already on board can become a visible problem. Root rot can develop quietly during the same window that the leaves are showing ordinary transit stress, so a plant that “seems fine, just droopy” can still be worth a root check by week two if the droop hasn’t started improving. Don’t treat these as mutually exclusive — if something doesn’t resolve on the shipping-stress timeline, that’s the signal to look closer, not to keep waiting.
What Commonly Gets Misdiagnosed
- Assuming any yellow leaf means rot. Losing one older leaf during normal acclimation is common and not a warning sign on its own.
- Waiting on a plant that’s actually rotting because the leaves still look mostly fine. Leaves are a lagging indicator for root problems — by the time they show it clearly, act quickly rather than waiting further.
- Treating for pests you can’t actually find. If you’re not seeing insects, webbing, or residue, look harder or wait for a clearer sign before treating — unnecessary treatment stresses a plant that may not need it.
When to Reach Out
If something looks wrong right at unboxing — the kind of visible damage described earlier in this guide — that’s covered by our standard DOA policy: contact us within 3 hours of opening the box, with photos or video required.
A root or pest issue that shows up later, during a day 8–14 check, is a different situation — it’s a care question, not a return/claim window, since that window has already passed by then. If you find rot or pests at that stage, the trimming and treatment steps above are the actual next move; there’s no separate claim process for something discovered this far into acclimation.
