About Turnip 'Market Express'

Brassica rapa var. rapa 'Market Express' · also called Market Express turnip, quick-maturing turnip · edible

'Market Express' is a fast, refined Japanese-type salad turnip producing smooth, pure-white roots in about 35-40 days. Sweet, crisp, and mild enough to eat raw, it is bred for quick succession sowings and cool-season growing. The tender greens are equally edible. Easy and reliable, it suits both spring and autumn crops and small-space beds.

Growth habit: Fast-growing cool-season annual forming a low rosette of edible leaves above a rounded, swelling white root. Bolts to a yellow-flowered seed stalk if stressed by heat or left past maturity.

What fertiliser turnip 'market express' actually wants — and why

Turnip 'Market Express' stores its crop underground, so the rule is the reverse of leafy plants — go easy on nitrogen, which sends energy into tops at the expense of roots.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for turnip 'market express': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed turnip 'market express', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For turnip 'market express':

A light feeder that crops fast. Rich pre-sowing compost is usually enough; an early dose of balanced fertiliser supports leaf and root growth. Avoid excess nitrogen, which produces lush tops and small, mild-to-the-point-of-bland roots. In practice: prepare the bed with well-rotted compost (not fresh manure), then little or no extra feeding through the season (spring through early autumn); a light potassium feed mid-growth at most.

The dormant-season rule matters more than the exact interval: skip feeding entirely when turnip 'market express' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for turnip 'market express'

Less is more for turnip 'market express'. If you feed at all, keep it light and low-nitrogen — the soil preparation does the work, and over-feeding actively spoils the crop.

Feeding always goes onto already-damp soil, never dry roots — water turnip 'market express' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the turnip 'market express' watering schedule.

Signs you are over-feeding turnip 'market express'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for turnip 'market express':

Large lush leafy tops and small, forked or hairy roots.
Split or cracked roots from a nitrogen-and-water surge.
All foliage and no usable crop at harvest.

Signs you are under-feeding turnip 'market express'

Genuinely uncommon in reasonable soil — these are not hungry plants.
Pale, weak tops and small roots only in very poor, exhausted ground.
Slow growth across the whole bed in long-uncultivated soil.

If the symptoms point at watering, light or roots rather than nutrition, the full turnip 'market express' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flushing is not the issue for turnip 'market express' — the equivalent care is avoiding fresh manure and high-N feeds entirely, and rotating beds so the soil is not over-rich from a previous hungry crop.

Organic vs synthetic feeds for turnip 'market express'

Organic options

Well-rotted compost worked in the season before, or for a previous crop, is ideal — never fresh manure. UK: garden compost, low-N blends; US: Espoma Garden-tone sparingly or finished compost. Lean and well-worked beats rich.

Synthetic / liquid feeds

If anything, a low-nitrogen, potassium-leaning feed only — UK: a high-potash feed mid-season at most, never a general high-N; US: a 5-10-10 sparingly. Most root crops crop best with no synthetic feed at all.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Fertilising turnip 'market express' — frequently asked questions

What fertiliser does turnip 'market express' need?

Low-nitrogen, with modest phosphorus and potassium for root development — ideally compost-improved soil rather than a high-N feed. Excess nitrogen forks the roots and grows lush tops instead of a crop. Turnip 'Market Express' stores its crop underground, so the rule is the reverse of leafy plants — go easy on nitrogen, which sends energy into tops at the expense of roots.

How often should I feed turnip 'market express'?

A light feeder that crops fast. Rich pre-sowing compost is usually enough; an early dose of balanced fertiliser supports leaf and root growth. Avoid excess nitrogen, which produces lush tops and small, mild-to-the-point-of-bland roots. A light feeder that crops fast.
