Plantico"How often should I water my plants?" is the single most-asked houseplant question — and the honest answer is it depends on the plant, the pot, the light, and the season. That's not a cop-out; it's why fixed rules like "every Sunday" kill so many plants. Here's how to water without guesswork.
The rule that actually works
Check the soil, not the calendar. Push a finger 5 cm (2 inches) into the soil. Dry at that depth → water thoroughly until it drains from the bottom. Still moist → wait and check again in a few days. Overwatering — watering on schedule regardless of need — is the #1 houseplant killer.
Typical watering frequencies by plant type
- Succulents & cacti: every 2–4 weeks; soil should dry completely
- Snake plants & ZZ plants: every 2–3 weeks; err on the dry side
- Monstera, pothos, philodendron: every 1–2 weeks when the top 5 cm dries
- Ferns & calatheas: every 3–7 days; keep lightly, consistently moist
- Orchids: roughly weekly, when roots turn silvery
These shift with conditions: more light, warmth, and smaller/terracotta pots mean more often; winter dormancy means much less.
Signs you're getting it wrong
- Overwatering: yellowing lower leaves, soil wet for days, soft stems, fungus gnats
- Underwatering: drooping that perks up after watering, crispy edges, lightweight pot
Let each plant set its own schedule
The real problem isn't knowing the theory — it's tracking it across eight plants with different needs. Plantico handles this: identify each plant by photo, save it to your collection, and the app builds a per-plant care plan with watering, misting and fertilizing reminders tuned to the species. When something's due, you get a nudge; when a plant looks off anyway, scan it and the disease diagnosis tells you whether water is the culprit.
Watering technique in 20 seconds
- Water slowly over the whole soil surface, not one spot.
- Stop when water runs from the drainage holes.
- Empty the saucer after 15 minutes — roots sitting in water rot.
