ZZ Plant

How your pot, light and size change it

Every 16 days is the starting point. Here’s how each part of your setup moves it on its own — the free schedule tool combines all of them for your plant.

How much water to give

Roughly 150–250 ml for a small pot, 250–500 ml for a medium one and 500–750 ml for a large plant. Pour slowly until a little runs out of the drainage hole, then tip away whatever collects in the saucer — a ZZ Plant sitting in water is the quickest way to rot its roots.

Watering ZZ Plant through the seasons

In spring and summer, growth picks up and warm days pull moisture from the pot faster. In a hot, dry spell our schedule tightens to about every 11 days. In autumn and winter the plant slows down and the soil stays damp for longer, so in cool, damp weather the schedule stretches to about every 22 days. Whatever the season, check the soil before you pour — the date is a reminder, the soil has the final say.

Signs of overwatering and underwatering

Because a ZZ Plant likes to dry out between drinks, too much water is the more common problem. Signs of overwatering: yellowing lower leaves, soft or mushy stems, soil that never seems to dry and a musty smell from the pot. Signs of underwatering: drooping or curling leaves, crispy edges and soil pulling away from the side of the pot. If you’re unsure, wait a day — a slightly thirsty plant recovers far more easily than a waterlogged one.

ZZ Plant watering FAQ

How often should I water my ZZ Plant?

Water your ZZ Plant about every 16 days. Let the soil dry out between waterings. Terracotta pots, bright light and small plants dry out faster; glazed pots, low light and larger plants hold water for longer.

Should ZZ Plant dry out between waterings?

Yes. Let the soil dry out between waterings. Push a finger right down into the pot before you pour, past the top couple of inches. Dry on top means very little on a plant like this — it would far rather be too dry than too wet. Lifting the pot works too: if it still has some weight to it, there’s water down there.

How much water does a ZZ Plant need?

Roughly 150–250 ml for a small pot, 250–500 ml for a medium one and 500–750 ml for a large plant. Pour slowly until a little runs out of the drainage hole, then tip away whatever collects in the saucer — a ZZ Plant sitting in water is the quickest way to rot its roots.

Should I water my ZZ Plant less in winter?

Usually, yes. Growth slows and the soil stays damp for longer, so in cool, damp weather the interval stretches to about every 22 days. Check the soil rather than sticking rigidly to the calendar.

Does a terracotta pot change how often I water a ZZ Plant?

Yes. Terracotta breathes and dries faster, so a ZZ Plant in terracotta needs water about every 14 days, compared with every 16 days in plastic and every 18 days in a glazed pot.

How do I know when my ZZ Plant needs water?

Push a finger right down into the pot before you pour, past the top couple of inches. Dry on top means very little on a plant like this — it would far rather be too dry than too wet. Lifting the pot works too: if it still has some weight to it, there’s water down there.
