Watering at a glance

Base rhythm	Keep soil consistently moist, watering whenever the surface starts to dry, often 2-3 times weekly
Spring / summer	Main season: aim for the equivalent of 2-3 cm of water per week as one or two deep soaks at the base, more in heat or during fruiting/sizing.
Autumn	Tail end of the season: ease back as temperatures drop and the plant winds down or ripens its last crop.
Winter	Off-season: most do not overwinter outdoors — store, mulch, or grow undercover; container plants need only occasional water if dormant.
Light	Direct sun (at least 4-6 hours)

'Market Express' is a fast, refined Japanese-type salad turnip producing smooth, pure-white roots in about 35-40 days.

The watering schedule, season by season

The base rhythm for turnip 'market express' is keep soil consistently moist, watering whenever the surface starts to dry, often 2-3 times weekly, 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): Main season: aim for the equivalent of 2-3 cm of water per week as one or two deep soaks at the base, more in heat or during fruiting/sizing.
Autumn (slowing down): Tail end of the season: ease back as temperatures drop and the plant winds down or ripens its last crop.
Winter (rest / dormancy): Off-season: most do not overwinter outdoors — store, mulch, or grow undercover; container plants need only occasional water if dormant.

How to tell turnip 'market express' needs water

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

Leaves wilt in the midday heat and do not fully recover by evening.
The soil surface is cracked or pulling away from the bed/pot edge.

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 turnip 'market express' for a day is almost always safer than over-watering it.

Overwatering vs underwatering turnip 'market express'

Signs you are overwatering

Yellowing lower leaves and waterlogged, airless soil.
Root rot and wilting despite wet soil; fungal leaf spots from constantly wet foliage.
Split or cracked fruit/roots from a sudden glut after drought.

Signs you are underwatering

Persistent wilting, small or bitter produce, premature bolting.
Blossom-end rot on tomatoes/peppers/squash from erratic moisture.
Tough, woody or cracked roots in root crops.

Shallow, frequent watering grows shallow roots and leaves turnip 'market express' prone to drought stress — cracked or woody roots, bitterness and premature bolting. Water deep and at the base, not little-and-often over the leaves.
