WARM SEASON GREEN MANURES

As a general guide sow in spring after all danger of frost has passed, usually mid-September; sow summer whenever good rainfall is expected; in tropical areas seeds can be sown right through the year whenever moisture is available. More specific sowing times are listed as part of the seed description.

Our standard postage is $9.50  for all orders which includes Bulk Seed Packs. The $5.50 postage fee for up to 100 standard packets of seed, only includes the smaller 10m²packets not the 1000m² or 4500m² seed packs or kits.

Due to high postage fees there is a higher cost for bulk seed in some Australian States.

Buckwheat         Organically certified

Fagopyrum esculentum

Buckwheat is an ancient food plant  that has been in use for over 9,000 years; it gives a whole new meaning to the word 'heirloom'. It is an annual warm season crop to 50 cm high. It has some drought tolerance and is frost tender. It germinates in 3 - 4 days, with a soil temperature of 20°C. Sow it 2.5 - 3.5 cm deep. The soil should be moist before sowing but do not over-water, buckwheat doesn't tolerate being waterlogged at any stage of growth. It will grow in a wide range of soils, including infertile ones, with a preferred pH range of 6 - 7.

It has a wide range of uses including:

• It makes a useful, fast growing, warm season, green manure that accumulates phosphorus and builds organic matter quickly. Use it as a fill-in between other crops. 

• The young sprouts can be harvested for salad.

• The high protein leaves can be used like spinach.

• The seeds are ground for a high-protein, gluten-free flour.

• The white flowers attract beneficial insects including hoverflies, lacewings and bees.

Growing as a grain crop:

A buckwheat grain crop requires a temperature during the growing season of between 13°C - 26°C. It takes 8 - 12 weeks from sowing to finished grain. Suitable areas are the cool highlands during summer and autumn to winter in southern Qld.

Growing as a green manure:

Flowering begins 4 weeks from sowing; dig the green manure whilst still flowering. If allowed to set seed it will often self-sow readily. Buckwheat used as a green manure has much wider sowing times than grain crops. In temperate areas sow September - February. In subtropical areas sow any time avoiding frost periods. In tropical areas other green manures are a better choice.
