When to Sow Warrigal greens Seeds

Although it is frost tender, Warrigal greens can be grown year-round in most climates. Avoid planting in extremely hot or cold weather which can affect germination and growth. Use the table below to identify the best time of year to sow Warrigal greens in your climate.



Warrigal greens plants are best grown in full sun or part shade. Choose a location that will receive at least 3 hours of full sun each day.

Warrigal greens plants need a well drained soil enriched with plenty of organic matter. Prepare soil by weeding it thoroughly, digging it over to loosen it and adding aged animal manure or compost. Keep the area free of weeds until planting. Learn more about preparing soil for planting here.

Warrigal greens plants can be grown in containers. If possible choose a variety that’s recommended for container growing. Use a good quality potting mix and make sure your container is large enough for mature plants; a minimum of 20 litres is recommended for Warrigal greens. During the growing season, keep in mind that container grown plants may need additional fertiliser to encourage healthy growth.

How to Sow Warrigal greens Seeds

Warrigal greens seeds do not require any treatment (eg soaking, stratification) before sowing.

Warrigal greens seeds can be sown directly into the garden OR seedlings can be raised in trays or other containers and transplanted to the garden once established.

Sow Direct

  1. Sow seeds directly in the garden 10mm deep and 50cm apart, with rows 50cm apart.
  2. Keep soil moist but never wet or dry.
  3. Seeds should germinate in around 7-12 days at a soil temperature of 25-30°C.
  4. Young seedlings will need protection from pests, pets and weather until they are established.

Raise Seedlings

  1. Fill trays, punnets or jiffy pots with a good quality seed-raising mix, or use soil starter pellets.
  2. Sow seeds 10mm deep.
  3. Keep soil moist but never wet or dry.
  4. Seeds should germinate in around 7-12 days at a soil temperature of 25-30°C.
  5. Transplant seedlings to the garden once they have their first true leaves and are large enough to handle (usually 5-10cm tall).
  6. Plant out, spacing plants 50cm apart, with rows 50cm apart.

Warrigal greens is a tender crop that’s sensitive to frost. Do not transplant seedlings or sow seeds outside until all danger of frost has passed.

How to Grow Warrigal greens

Warrigal greens plants may need watering during the growing season. Water when the soil is dry about 5cm below the surface (test this by scratching away a little soil with your finger). Water deeply in the early morning or late afternoon. Avoid watering the leaves of plants to avoid fungal diseases. Learn more about watering here.

If soil was well prepared no extra fertiliser should be necessary. In poor soil or to give your plants an extra boost, application of a high-nitrogen fertiliser or one formulated for leafy greens or herbs can be beneficial:

  • Apply slow release fertiliser at the recommended rate when transplanting or when seedlings are 5-10cm tall.
  • Apply liquid fertiliser at the recommended rate and frequency during the growing season.

How to Harvest Warrigal greens

Warrigal greens should be ready to harvest in approximately 50 days.

Warrigal greens leaves are ready to harvest when they are large enough to eat, and can be harvested as needed. Harvest leaves and stems by cutting them with snips, leaving some on the plant for future growth. Warrigal greens leaves contain oxalates and should be soaked on cold water for 30 minutes or blanched before eating. Leaves can be stored short term in a perforated plastic bag in the fridge. For longer term storage Warrigal greens can be blanched and then frozen.
