More details about Tadorna Organic

Tadorna Organic leek seeds are CERTIFIED ORGANIC! Very reliable, vigorous leeks with dark blue-green leaves and medium length, blanched shanks. Harvest October to December from this very hardy, naturally uniform leek. Tadorna will overwinter in mild seasons. The 18-20cm (7-8") long shanks are easy to clean and bright white, with strong, sweet flavour. Harvest after frost and taste the difference - the flavour is really enhanced. Leeks are a great crop to dedicate space to as they can be harvested over a long period. This cold hardy leek is a superb choice for harvesting in the fall and winter when many other vegetables have given up the ghost.

Timing

Timing
Start summer/fall harvest leeks 6-8 weeks before the last frost date, in flats indoors. Start winter harvest leeks indoors from March to mid-June. In mild winter areas, start them in a humus-rich nursery bed outside, and then transplant. Optimal soil temperature: 10-25°C (50-75°F). Seeds should sprout in 10-16 days.

Starting

Starting
In flats: Sow seeds 5mm (¼”) deep, about 1cm (½”) apart. Transplant when 20cm (8″) tall. Space 20cm (8″) apart in rows 45cm (18″) apart. Rows can be as narrow as 20cm (8") if planting in raised beds or other situation where weeding will be simple.

Growing

Growing
Ideal pH: 5.-6.5. Leeks have short roots, so the benefit from fertile soil with lots of compost and ½ cup balanced organic fertilizer worked in beneath each 2m (6′) of row. Traditional garden wisdom recommends using a dibber to make holes 15cm (6″) deep. Transplants are then set at the bottom of the hole and the hole is left unfilled – rain will fill it in as the leek grows. To blanch further up the stem, hill soil up around the stem as the leek grows, or mulch with straw.

However, the wise and much loved garden writer Linda Gilkeson asserts that there is no need to plant leeks into holes or trenches. She recommends transplanting the seedlings only at the depth of the soil plug they grow in. They will still produce nice, tall, blanched shanks, with no soil grains between the leaves.

In late fall, mulch around leeks as high up the stems as possible. If the forecast is for weather below -10° (14°Ï‚ cover them with a blanket or tarp.

Days to maturity: From transplant date.

Harvest

Harvest
Dig at any size, as needed. If winter harvest leeks freeze solid, wait until they thaw out during a warm spell to harvest.
