About Portulaca grandiflora 'Sundial Mango'

Portulaca grandiflora 'Sundial Mango' · also called Sundial Mango Portulaca, Mango Moss Rose · flowering

'Sundial Mango' is a moss rose bred from the Sundial series, with double, rose-like blooms in warm mango-orange over succulent, needle-like foliage. Exceptionally heat- and drought-tolerant, this low, spreading annual thrives in baking sun and poor, gritty soil. The Sundial selection opens its flowers earlier and in duller weather than older strains.

Ideal humidity: 30-50%

Watch for — Stem and root rot: Caused by overwatering or heavy, wet soil. Plant in gritty, fast-draining mix and water only when thoroughly dry.

The watering schedule, season by season

Portulaca grandiflora 'Sundial Mango' stores water in its thick leaves and stems, so when in doubt, wait — it survives drought far better than soggy soil. The base rhythm for portulaca grandiflora 'sundial mango' is when the soil is dry several centimetres down, roughly every 7-10 days; less in cool spells, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 7-10 days.
Autumn (slowing down): Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
Winter (rest / dormancy): Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.

A succulent that stores water in its leaves and stems, it tolerates drought well. Water sparingly and let the soil dry thoroughly between drinks. Overwatering is the main killer.

How to tell portulaca grandiflora 'sundial mango' needs water

A calendar is the worst way to water portulaca grandiflora 'sundial mango'. Check the plant and the soil instead — for this species, look for these signals in order:

The lower or oldest leaves feel slightly soft or look a touch wrinkled.
The pot is noticeably light when lifted.
Soil is dry several centimetres down, not just at the surface.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering portulaca grandiflora 'sundial mango' for a day is almost always safer than over-watering it.

Overwatering vs underwatering portulaca grandiflora 'sundial mango'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For portulaca grandiflora 'sundial mango' specifically:

Signs you are overwatering

Leaves turn translucent, yellow, soft and mushy — classic overwatering.
Lower stem darkens or goes squishy at soil level.
Whole rosettes or sections drop at the lightest touch.

Signs you are underwatering

Leaves pucker, wrinkle or curl inward — a harmless thirst signal that reverses fast after a soak.
Older leaves dry crisp from the tips first.

Overwatering is the number-one killer of portulaca grandiflora 'sundial mango'. The thick leaves are a water tank — a slightly thirsty plant recovers in a day; a waterlogged one rots from the roots up.

Water quality notes

Tap water is generally fine for portulaca grandiflora 'sundial mango'; the soak-and-dry rhythm matters far more than water type.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For portulaca grandiflora 'sundial mango', the levers that matter most are:

A gritty, free-draining mix is essential — ordinary potting soil holds too much water for this plant.
Terracotta dries faster and is more forgiving than plastic or glazed ceramic.
More light and warmth speed drying, so the interval shortens in peak summer — always check, never assume.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of portulaca grandiflora 'sundial mango'.
