Eastern Promise: Growing Asian Greens

, written by Benedict Vanheems gb flag

Asian greens make the perfect fall crop

With the second half of summer well underway it’s tempting to let the kitchen garden coast towards the lengthening shadows of autumn. With so much coming off the productive plot it is hard to imagine things slowing down, but slow down they will. Unless, that is, you take advantage of the many vegetables that can still be sown at this time of year. These second-wind crops follow seamlessly on from recently excavated vegetables to give a harvest either before the end of the growing season or, with a little shelter from the elements, right through the fall and on into winter.

Asian Greens

One family of vegetables that can be started off from now is the Asian greens. While for many crops it’s a matter of ‘squeezing them in’ in what remains of the growing season, these quick-growing and hardy leaves positively thrive from late summer in a way that’s simply not possible earlier on in the year.

Asian greens include the likes of bok choy, mizuna and the mustards. I’ve long been a fan of these spicy fellows; their piquant notes and colorful, textured leaves are real charmers on the plot and dinner plate. Cut into the finest ribbons with the sharpest knife they’ll pep up any salad, while their thick midribs give a satisfying crunch if shown the wok for the briefest of moments.

The Perfect Fall Crop

There are compelling reasons for sowing these Eastern delights as the nights begin to draw in. Asian greens put on leafy growth in response to shortening day length, which means none of the bolting – or running to seed – problems that so frustrate attempts to grow them in spring. I could never work out why my diligently sown rows of stir-fry leaves almost immediately stretched to flower. Having switched my sowing dates to late summer I can carry on cutting leaves through the winter before they eventually rise up to seed in spring. In this way I’ll achieve a steady six months’ of leaves, rather than having to fine-time the fleeting two to three-week harvest window of early summer.

Growing these lush leaves as the weather cools off also means there’s far less in the way of pests to intimidate. Along with the usual slugs, the flea beetle is the biggest antagonist. Though by no means disastrous, these tiny pinging insects will nibble literally hundreds of equally tiny holes into the leaves, rendering them tough and certainly lacking in the looks department. After midsummer flea beetle activity settles down, giving cleaner cuts of leaves befitting of any self-respecting dinner table.

So let’s meet some of the family members that make up the Asian greens. Here are some of my personal favorites (there are plenty more!)

  • Mizuna: Their feathery leaves give no hint of the pleasingly peppery tang to come. Cut individual leaves from the outside of the plants as they reach maturity, or lift complete plants.
  • Mustards: Available in all manner of shapes, sizes and colors, mustards are the most varied of the Asian greens. Look out for the exceptionally hardy ‘Green in the Snow’ or for a milder, almost sweet-tasting alternative plumb for impressively frilly twins of ‘Golden Streaks’ or ‘Ruby Streaks’. When harvesting, cut horizontally right across the plants to leave the smallest leaves at the centre of the plant to grow on for the next cut.
  • Bok Choy: This stir-fry staple has an irresistibly crunchy midrib and clean, refreshing taste. While it can cope with light frosts, it is best grown under some protection – a cold frame or unheated greenhouse would be ideal. I favour the hardier-than-average F1-hybrid variety ‘Joi Choi’.
  • Tatsoi: Smaller leaves than bok choy but considerably more weather proof, holding its own in temperatures down to -10°C (14°F). The glossy leaves form a ground-hugging rosette that’s undisturbed by winter winds.
  • Chinese Cabbage: If you can offer a moist, rich soil then the pale-leaved Chinese cabbage will thrive. Offer it a little protection when the weather begins to cool off and you could be enjoying hearty heads of tightly packed leaves in as little as 10 weeks. Enjoy a bonus crop by cleanly cutting the heads away to leave a stump in the ground; a secondary cut of smaller leafy shoots will follow within a few weeks.

All of these eastern delights are straightforward to grow and share similar cultural requirements. Don’t let slugs get the upper hand; if they are a particular nuisance on your plot then start seedlings off in modules before planting them out to give a bit of a head start. Allow plenty of space between plants – at least 20cm (8in) in each direction would be advisable and gives the slimy mollusks fewer opportunities to lurk in the undergrowth. Always pick off older, yellowing leaves and weed meticulously to ensure plenty of light and air around plants during this often wetter time of year. Regular harvesting will keep plants productive and healthy – and you stocked with handsome leaves.

"I find Real Seeds fabulous for their range of seed suited to the UK climate and the quality of their seed. Their range of oriental greens is amazing. http://www.realseeds.co.uk/"

"Can you be more specific about where the seeds can be found. I live in SE part of Texas. What are the better varieties for this area"
Susan on Sunday 7 August 2011
"like the idea of keeping the garden growing."

"can you grow these greens in zone 9 this month August?"
irene on Sunday 7 August 2011
"Irene in Zone 9 you can use Labor Day (first weekend of September) as your starting point for fast-growing fall greens. Use the GrowVeg planner with the split season option turned on for specific dates, but traditionally early September is the start of the greens season where summers are hot."
