About Turnip 'Tokyo Cross'
Brassica rapa var. rapa 'Tokyo Cross' · also called Tokyo Cross turnip, Japanese turnip · edible
'Tokyo Cross' is an F1 Japanese turnip producing uniform, smooth white globes very fast, often in just 35-40 days. Mild, sweet and tender, it can be eaten raw and rarely turns woody if harvested young. Bolt-resistant and reliable, it suits successional sowing through the season. Sow direct in full sun in cool conditions.
Preferred mix: Fertile, light, free-draining loam
Watch for — Splitting: Because growth is so rapid, leaving roots in the ground too long or heavy rain after dry spells splits them; harvest promptly at golf-ball size.
Why turnip 'tokyo cross' needs this mix
Turnip 'Tokyo Cross' is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Turnip 'Tokyo Cross' grows fast and has a big crop to fill, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons turnip 'tokyo cross' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves turnip 'tokyo cross' — growth stalls, leaves pale, and yields collapse.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Turnip 'Tokyo Cross' needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for turnip 'tokyo cross'?
Turnip 'Tokyo Cross' does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
