Dieffenbachia
Dieffenbachia seguine
Water about every 5 days.
Keep the soil evenly moist — don't let it fully dry out. Feel just under the surface before you pour. You’re after barely damp here, not bone dry — and if it’s still properly wet, hold off. Even moisture isn’t the same as constantly soaked.
How your pot, light and size change it
Every 5 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.
| Factor | Setup | Water |
|---|---|---|
| Pot | Terracotta | every 4 days |
| Plastic | every 5 days | |
| Glazed ceramic | every 6 days | |
| Light | Bright | every 4 days |
| Medium | every 5 days | |
| Low | every 6 days | |
| Plant size | Small | every 5 days |
| Medium | every 5 days | |
| Large | every 6 days |
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 — the aim is moist soil, not a waterlogged pot.
Watering Dieffenbachia 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 4 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 7 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
A Dieffenbachia prefers steady moisture, so letting it dry out completely is the easier mistake to make. Signs of underwatering: drooping, curling or crispy leaves and soil pulling away from the side of the pot. Signs of overwatering: yellowing leaves, soft stems and soil that stays soggy for days. Aim for soil that feels like a wrung-out sponge.
Dieffenbachia care guide
Large tropical plant with bold patterned cream and green leaves. Prefers bright, indirect light. Water when top inch of soil feels dry. Prefers 65-75°F and moderate humidity. Use peat-based soil. Grows 3-6 feet tall. Prune to control height. Toxic if ingested; keep from children and pets. Generally pest-resistant.
Dieffenbachia watering FAQ
How often should I water my Dieffenbachia?
Water your Dieffenbachia about every 5 days. Keep the soil evenly moist — don't let it fully dry out. Terracotta pots, bright light and small plants dry out faster; glazed pots, low light and larger plants hold water for longer.
Should Dieffenbachia dry out between waterings?
No — keep the soil evenly moist and don't let it dry out completely. Feel just under the surface before you pour. You’re after barely damp here, not bone dry — and if it’s still properly wet, hold off. Even moisture isn’t the same as constantly soaked.
How much water does a Dieffenbachia 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 — the aim is moist soil, not a waterlogged pot.
Should I water my Dieffenbachia 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 7 days. Check the soil rather than sticking rigidly to the calendar.
Does a terracotta pot change how often I water a Dieffenbachia?
Yes. Terracotta breathes and dries faster, so a Dieffenbachia in terracotta needs water about every 4 days, compared with every 5 days in plastic and every 6 days in a glazed pot.
How do I know when my Dieffenbachia needs water?
Feel just under the surface before you pour. You’re after barely damp here, not bone dry — and if it’s still properly wet, hold off. Even moisture isn’t the same as constantly soaked.
