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.

Mature size: Tops reach 20-30 cm tall; roots harvested young at 4-6 cm diameter, around golf-ball to small-tennis-ball size.

Watch for — Flea beetle damage: Flea beetles pepper the seedling leaves with tiny holes, checking growth. Cover with fine insect mesh from sowing and keep plants vigorously watered to grow through damage.

Indoor size vs how big it gets in the wild

Turnip 'Market Express' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect tops reach 20-30 cm tall. In the ground with no restriction it is a completely different plant — roots harvested young at 4-6 cm diameter, around golf-ball to small-tennis-ball size. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.
