A vibrant hybrid tickseed bearing rich ruby-red, semi-double daisy flowers through summer and into autumn. Forms a tidy, low mound of fine-textured foliage. Heat and drought tolerant once established. A long-blooming perennial that attracts butterflies and bees. Not listed as toxic by the ASPCA.

The watering schedule, season by season

Coreopsis 'Ruby Sunset' flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for coreopsis 'ruby sunset' is when the top 3-5 cm of soil is dry, roughly every 7-10 days, 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 every 7-10 days.
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.

Drought-tolerant once established. Overwatering or poor drainage is the primary cause of failure; allow soil to dry between waterings. Mulch to conserve moisture during establishment.

How to tell coreopsis 'ruby sunset' needs water

A calendar is the worst way to water coreopsis 'ruby sunset'. 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 coreopsis 'ruby sunset' for a day is almost always safer than over-watering it.

Overwatering vs underwatering coreopsis 'ruby sunset'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For coreopsis 'ruby sunset' 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.

Erratic watering — bone dry then flooded — makes coreopsis 'ruby sunset' drop its buds and flowers. Consistency through the budding period is what protects the display.

Water quality notes

Tap water is generally fine for coreopsis 'ruby sunset' unless your water is very hard; rainwater is a safe default if leaf tips brown.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For coreopsis 'ruby sunset', 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 coreopsis 'ruby sunset'.
