How to tell chrysanthemum 'emperor of china' needs water

A calendar is the worst way to water chrysanthemum 'emperor of china'. 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.

Overwatering vs underwatering chrysanthemum 'emperor of china'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For chrysanthemum 'emperor of china' specifically:

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.

Signs you are underwatering

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 chrysanthemum 'emperor of china', 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 chrysanthemum 'emperor of china'.
