Scaevola

Scaevola aemula

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 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 Scaevola 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 Scaevola 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.

Scaevola watering FAQ

How often should I water my Scaevola?

Water your Scaevola 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 Scaevola 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 Scaevola 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 Scaevola 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 Scaevola?

Yes. Terracotta breathes and dries faster, so a Scaevola 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 Scaevola 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.
