The base rhythm for prunus subhirtella 'autumnalis' is water regularly during establishment; mature trees need watering only in prolonged summer drought, 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 (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

How to tell prunus subhirtella 'autumnalis' needs water

A calendar is the worst way to water prunus subhirtella 'autumnalis'. Check the plant and the soil instead — for this species, look for these signals in order:

The top 2-3 cm of soil is dry to the touch.
Leaves or flower stems lose turgor and start to droop.
Buds stall or the pot feels light.

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 prunus subhirtella 'autumnalis' for a day is almost always safer than over-watering it.

Signs you are overwatering

Yellowing leaves, bud drop, and a heavy, constantly wet pot.
Mushy stems or crown rot at soil level.
Fungus gnats and a sour soil smell.

Wilting, bud and flower drop, and crispy leaf edges.
A faded, stressed look and a rootball that has pulled from the pot sides.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For prunus subhirtella 'autumnalis', the levers that matter most are:

A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
Empty the saucer after every water so the roots are never sitting in run-off.

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 prunus subhirtella 'autumnalis'.
