Timing

Timing
Mustards are cool season plants that grow quickly and then bolt. Direct sow with frost protection as early as late winter or without protection from early to late spring. Sowing short rows every 3 weeks allows for a continuous harvest of both baby leaves and full sized plants. Sow again in late summer for late fall and winter harvests. Optimal soil temperature: 21°C (70°F). Seeds should sprout in 5-10 days.

Starting

Starting
If growing to full size, sow 3-4 seeds in each spot you want a plant to grow. Sow 5mm-1cm (¼-½”) deep and thin to the strongest plant, spaced 10-15cm (4-6″) in the row. All mustards can be grown in containers for baby salad greens. Sow these as you would mesclun mixes, with seeds spaced as near as possible to 1cm (½”) apart.

Days to Maturity

Days to Maturity: From direct sowing.

Growing

Growing
Ideal pH: 6.0-6.5. One cup of complete organic fertilizer will provide nutrition for 3m (10′) of row. Water regularly. Expect mustards to bolt in hot weather. Provide protection in winter by using a cloche or heavy row cover. At all other times, plan on growing fast and harvesting fast, like spinach. Planting short rows every two weeks works best for the home garden for a constant harvest.

Harvest

Harvest
Cut individual leaves, or the whole plant at whatever stage of maturity you desire. Young leaves tend to be more tender and less powerfully flavoured as mature leaves. Some varieties will develop a slight bitterness in fully mature leaves. The leaves can be blanched (or run through a food processor) and then frozen, or even dried and flaked for soup mixes. But the plants are so cold hardy, fresh leaves should be available to the determined gardener 12 months of the year. Whole plants can also be pickled for long term storage.

Seed Info

Seed Info
In optimal conditions at least 70% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 400 seeds, per acre: 174M seeds.

Diseases & Pests

Diseases & Pests
Slugs and woodlice (sow bugs) may nibble young seedlings, but overall, these plants are trouble free. Keep the garden free from debris and excess water, where both of these pests like to go during the day. If leaves show lots of tiny holes, flea beetles are the problem. Prevent early spring infestations by using lightweight row cover.

How to Grow Pac Choi and Choi Sum

Step 1

Timing

All are cool season plants that grow quickly and then bolt. Direct sow with frost protection (a cloche or heavy row cover) as early as late winter, or without protection from four weeks before the last frost date to eight weeks after. Sowing short rows every 2-3 weeks allows for a fairly constant harvest time. Sow again in late summer, and provide frost protection as the first frost date approaches.

Step 2

Starting

Sow 3-4 seeds 5mm-1cm (¼-½”) deep in each spot you want a plant to grow. Thin to the strongest plant at a spacing of 15-20cm (6-6″) between plants in rows 30-45cm (12-18″) apart.

Step 3

Growing

Ideal pH: 6.0-6.8.

1 cup of complete organic fertilizer will provide sufficient nutrition to 3m (10′) of row. Choi Sum is harvested just before it flowers, so keep a close watch on each row. Pac Choi can be harvested at any stage, but if you want full-sized plants, watch for signs of bolting. Flower buds will appear at the centre of each plant, and a stem will form quickly as the plant turns from urn-shaped into a tall cone. Harvest as quickly as possible once flower buds are visible. Keep plants well-watered throughout their growth.

Step 4

Germination

Days to maturity: From direct sowing.

In optimal conditions at least 70% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 260 seeds, per acre: 114M seeds.

Step 5

Harvest

Use a sharp knife to cut the plants at ground level when they are ready to harvest. They will not grow back like some other crops, so plant several short rows every couple of weeks for a longer harvest.
