How to grow ruby saltbush
Overview
Ruby saltbush (Enchylaena tomentosa) is a low-growing Australian native shrub with fleshy, ruby-red berries that are both ornamental and edible. It is exceptionally drought-tolerant and ideal for dry, low-maintenance gardens. Key requirement: well-drained soil and full sun.
Soil Preparation
Prefers well-drained sandy loam with a neutral to slightly alkaline pH (6.5–8.0). If planting in heavy clay, raise beds or mix in coarse sand and organic matter to improve drainage. Avoid poorly drained soils.
Growing Guide
Plant ruby saltbush in full sun with well-drained sandy or loamy soil. Space plants 1–2 metres apart. Sow seed directly after the last frost at 5 mm depth, or plant cuttings in spring. Water sparingly once established; overwatering leads to root rot. Prune after fruiting to promote compact growth.
Sowing
Sow seed directly in spring or autumn at 5 mm depth, covering lightly. Keep moist until germination (14–21 days). For best results, nick the seed coat or soak seeds overnight. Cuttings taken from semi-hardwood in late spring also root readily.
Care
Feed lightly with a balanced native fertiliser in early spring. Prune after fruiting to remove spent stems and shape the plant. Mulch around the base to suppress weeds and retain moisture, but avoid piling mulch against the stem.
Companion Planting
Pair with other low-growing Australian natives like creeping boobialla (Myoporum parvifolium) and prostrate grevilleas. Avoid planting near heavy feeders like tomatoes or corn, as ruby saltbush prefers lean soils.
Common Pests & Risks
Ruby saltbush is generally pest-free in Australian gardens. Occasional scale or aphids can be treated with horticultural oil. Birds may eat the berries; netting can protect the harvest if needed.
Harvesting
Harvest ripe berries when they turn bright ruby red and slightly soft, typically from late summer to autumn. Pick sparingly to allow the plant to continue producing. Berries are best used fresh or dried.
In the Kitchen
Berries can be eaten fresh, dried, or made into jams and sauces. They have a mildly sweet, earthy flavour. Remove the central seed before using in recipes. Store fresh berries in the refrigerator for up to a week.
Troubleshooting
Yellow leaves: overwatering or poor drainage—reduce watering and improve soil drainage. Leaf drop: cold stress in exposed sites—provide frost protection during extreme events. Poor fruiting: insufficient sunlight—ensure full sun exposure. Leggy growth: too much nitrogen or shade—stop feeding and move to sunnier spot. Berry rot: excessive moisture—pick berries promptly and avoid overhead watering.
