How to tell hyacinthus orientalis 'city of haarlem' needs water

A calendar is the worst way to water hyacinthus orientalis 'city of haarlem'. 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.

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

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 hyacinthus orientalis 'city of haarlem', 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 hyacinthus orientalis 'city of haarlem'.
