Peace Lily, Spider Plant, and Pothos: What 67 Health Checks Found

We found 67 completed AloeThere health checks identified as three familiar houseplants: 25 peace lilies, 20 spider plants, and 22 pothos plants. AloeThere flagged 57 of those 67 checks, or 85.1%, as unhealthy.

One top finding appeared in every group. Among the checks flagged unhealthy, “water excess or uneven watering” led in 20 of 24 peace lily checks, 14 of 18 spider plant checks, and 7 of 15 pothos checks.

These are early species-level patterns, not rankings of which houseplant is healthiest. Each group is only 20 to 25 checks, and people usually scan a plant because they already see a concern.

Across these three species groups, excess or uneven watering was the most frequent leading finding. The strength of that pattern differed by species.

The 67-check comparison

The percentages describe submitted checks, not every peace lily, spider plant, or pothos. A healthy plant sitting on a shelf is less likely to appear in a health-check dataset than a plant with drooping, yellowing, or damaged leaves.

We also should not treat the difference between 96.0% and 68.2% as evidence that peace lilies are inherently less healthy than pothos. Scan selection, growing conditions, image quality, and species-identification error can all affect these small groups.

How we selected the species groups

We reviewed AloeThere health checks completed from July 2 through August 24, 2026. The full sample included 921 checks where AloeThere identified a plant and returned a clear health result. For this comparison, we included only plant types with at least 20 checks. Peace lily, spider plant, and pothos met that threshold.

The plant names and health findings are based on the photos and care details submitted with each check. They are not botanist-confirmed identifications or laboratory diagnoses.

We also repeated the comparison using only checks with a plant-identification confidence score of at least 0.50. The overall pattern remained the same:

That second comparison reduces the spider plant group to 19 checks. It is another reason to treat these as early observations rather than settled species benchmarks.

Peace lily checks showed the strongest watering signal

AloeThere flagged 24 of the 25 peace lily checks as unhealthy. In 20 of those 24 unhealthy checks, or 83.3%, “water excess or uneven watering” was the leading result.

Water deficiency led in 2 of the 24 unhealthy peace lily checks. In other words, the data did not support treating every drooping peace lily as thirsty.

This is especially useful because a dramatic change in leaf posture can tempt an immediate watering. Check the root zone first. If the soil is still wet and the pot remains heavy, adding more water may move the plant in the wrong direction. If the root ball is dry, water thoroughly and let the excess drain.

Spider plant checks showed a similar pattern

AloeThere flagged 18 of 20 spider plant checks as unhealthy. Excess or uneven watering was the leading result in 14 of those 18 checks, or 77.8%.

The remaining four unhealthy spider plant checks each had a different top result: nutrient deficiency, lack of light, mechanical damage, or senescence. Each occurred once, which is far too small for a species-level conclusion.

The useful lesson is not that every spider plant problem comes from water. It is that root-zone moisture deserves an early check, while a mismatch between the moisture and the visible damage should widen the investigation.

Pothos checks were more mixed

AloeThere flagged 15 of 22 pothos checks as unhealthy. Excess or uneven watering led in 7 of those 15 checks, or 46.7%.

Nutrient deficiency appeared as the top result in 3, mechanical damage in 2, an insect-related category in 2, and water deficiency in 1. Only the watering category had enough observations to discuss as a pattern, and even that group is small.

Pothos leaves can yellow, droop, or develop brown areas for several reasons. Our guide to why plant leaves turn yellow explains why soil moisture, roots, light, pests, and nutrition should be checked together.

What the three species have in common

Across the three groups, 41 of the 57 unhealthy checks, or 71.9%, had excess or uneven watering as the leading finding.

That combined number is driven heavily by the peace lily and spider plant groups. It does not mean 71.9% of these species have a watering problem in ordinary homes. It means the watering category dominated this concern-selected set of unhealthy checks.

The common care response is a soil-first inspection:

1. Check moisture below the surface in more than one spot.
2. Compare the pot's weight with its weight after watering.
3. Confirm that excess water can drain completely.
4. Check for water hidden inside a decorative outer pot.
5. Consider whether low light or dense soil is slowing the dry-down.
6. If the soil condition does not match the result, investigate roots, pests, light, and physical damage before acting.

For a full routine, use AloeThere's soil-first indoor watering guide. Our separate analysis of overwatering versus underwatering findings explains why similar-looking leaf stress can call for opposite responses.

What we need before stronger species claims

Twenty to 25 checks can reveal a signal worth watching, but it is not enough for fine-grained claims about cultivars, seasons, indoor versus outdoor growing, or specific symptoms.

We plan to revisit these comparisons as each species reaches a larger sample and more plants receive follow-up checks. That could help us understand not only what appears in an initial health check, but also what changes after care.

A careful way to use plant health analysis

Species context can make a health result more useful, but it does not remove uncertainty. A photo-based check cannot feel the soil or inspect hidden roots on its own.

If your peace lily, spider plant, or pothos looks unwell, AloeThere: Plant Health can analyze photos of the plant and organize the leading possibilities. Use that result with what you can directly observe in the pot and growing space.
