Growing Guide

Warrigal Greens are best planted in spring (September to November) when soil temperatures warm above 15°C, though gardeners in subtropical and warm temperate zones can also sow in autumn (March to May) for a winter crop. In cool temperate regions, wait until after the last frost before planting out seedlings or direct sowing.

Soil Preparation: Warrigal Greens tolerate poor soils remarkably well but perform best in free-draining sandy or loamy soil with a pH of 6.0–7.5. Incorporate a light application of compost before planting and ensure excellent drainage, as waterlogging is the primary cause of failure.

Watering: Once established, this plant is exceptionally drought hardy. Water deeply once or twice per week during the first month, then reduce to fortnightly watering or rely on rainfall in temperate zones. In arid climates, a weekly deep water during summer is sufficient.

Feeding: Apply a balanced slow-release fertiliser at planting and a light liquid feed of seaweed solution every four to six weeks during the growing season to encourage lush leaf production.

Harvesting: Begin harvesting young shoot tips and leaves from eight to ten weeks after planting. Regular picking every one to two weeks actively stimulates bushy new growth and prevents the plant from becoming woody. Always blanch leaves in boiling water for two minutes before eating to neutralise oxalic acid, then rinse in cold water before use.

🤝 Good Companions

Warrigal Greens pair excellently with tomatoes zucchini beans and sweet corn acting as a living mulch that retains soil moisture suppresses weeds and keeps root zones cool during hot Australian summers. Their spreading habit fills gaps between taller crops without competing aggressively for nutrients creating a productive layered garden system.

❌ Avoid Planting With

Avoid planting Warrigal Greens alongside other sprawling groundcovers such as pumpkin or cucumber as the competing vigorous vines will tangle and create pest-harbouring dense masses that restrict airflow and increase disease risk. Root vegetables like carrots and beetroot can also be crowded out by the plant's spreading stems.

🐛 Pests & Diseases

Warrigal Greens are remarkably pest-resistant, though slugs and snails may target young seedlings in moist conditions — control these with iron-based organic baits or crushed eggshell barriers around plants. In humid subtropical gardens, powdery mildew can occasionally appear on older foliage; improve airflow by thinning crowded stems and apply a diluted milk spray or neem oil solution as an organic preventative measure.

🌱 Fertilising

At planting, work a handful of balanced slow-release organic fertiliser such as pelletised chook manure or a native-appropriate low-phosphorus blend into the soil. During the growing season, apply a liquid seaweed and fish emulsion fertiliser every four to six weeks to promote vigorous, tender leaf growth without encouraging excessive soft sappy stems.

✂️ Pruning & Training

Trim back long sprawling stems by one-third every six to eight weeks to encourage a bushier, more productive plant and prevent it from smothering neighbouring crops. After flowering or if plants become woody and straggly in late summer, cut back hard to within 15 centimetres of the base and water well to promote fresh productive regrowth.

🔬 Propagation

Warrigal Greens are most easily propagated from seed sown directly into the garden bed or into small pots, noting that soaking seeds in warm water for 24 hours before sowing significantly improves germination rates, with seedlings typically emerging within 10 to 21 days. Stems also strike readily as cuttings — simply press a healthy 15-centimetre tip cutting into moist sandy potting mix, keep it shaded and consistently moist, and roots will develop within two to three weeks.
