"How often should you water houseplants? A decision tree, not a schedule"

Ask five plant people "how often should I water my plants?" and you'll get five different answers — because the right answer depends on the plant, the pot, the light, and the season. A fixed calendar schedule is exactly how most houseplants die.

Here's the decision tree I actually use, and it works for every plant in the house.

1. Check the soil, not the date. Stick a finger about one knuckle deep. Water when that depth is dry. For most tropical houseplants (monstera, pothos, philodendron, peace lily) that's the whole rule — about once a week in summer, less in winter.

2. Succulents and cacti wait longer. They store water in their leaves and roots rot fast. Let the soil dry out completely — sometimes for two or three weeks — then give a thorough soak. A jade plant, snake plant, or aloe wants neglect, not attention.

3. Deep-water, then drain. When you do water, water until it runs out the drainage holes, then tip away the excess after 15 minutes. Small frequent sips keep the topsoil wet and the rootball dry, which is the classic recipe for yellow leaves.

4. Watch the leaves. Drooping that perks up within a few hours of watering = underwatered. Drooping that stays soft and yellow after watering = overwatered, the harder one to fix. Crispy brown edges are usually low humidity, not thirst.

5. Adjust for environment. More light and warmth = faster drying = water more often. Winter, AC, or low light = the opposite. A plant that needed water every 6 days in July can go 12+ days in January.

Each plant species has slightly different quirks though. I keep a per-plant reference at https://everleaf.vercel.app — you pick a plant (snake plant, pothos, monstera, fiddle leaf fig, peace lily, calathea, and 45 more) and it gives watering, light, humidity, and soil guidance specific to that species.

The shortest summary: check the soil, water deeply, let it drain, and read the leaves. Skip the calendar and the plant will forgive almost everything else.
