Quandong Tree

Quandong (Santalum acuminatum) is one of those uniquely Australian natives that gardeners either dream about growing—or grow with quiet pride. Known for its striking red fruit and blue-grey foliage, this semi-parasitic small tree is a staple in bush tucker traditions and a fascinating plant to grow at home.

It’s not the easiest seedling to raise, but don’t let that put you off. With a bit of planning and patience, you can absolutely grow your own Quandong patch, whether you’re in the arid outback or a dry temperate zone. Let’s dive in!

🥚 Sowing from Seed: Trays vs. Direct

Quandong seeds are large, hard-coated, and a little fussy about germination. They also need a host plant to survive (we’ll come back to this), so that adds a layer of complexity but it’s manageable once you understand the rhythm.

🌱 Starting in Trays (Recommended for Control)

Why it works: You get to monitor moisture levels closely, track early germination, and pair your Quandong seedling with a host in a controlled way.

Steps:

1. Pre-treat your seeds – Scarify the hard outer coat using sandpaper or soak in boiling water (let them cool in the water overnight). This breaks dormancy.
2. Use deep pots or forestry tubes – Quandongs develop a long taproot early on. Shallow trays don’t suit them.
3. Host pairing: Sow a suitable fast-growing native host species—like Acacia acinacea, Rhagodia spinescens, or Myoporum—in the same pot at the same time.
4. Medium: Use a native potting mix with excellent drainage. Avoid heavy composts or fertilisers.
5. Position: Full sun is ideal—even from germination—so don’t coddle them in too much shade.

Germination can take 3–12 months, so this is a waiting game. Water lightly and consistently but don’t overdo it—they hate soggy roots.

🌿 Direct Sowing (Advanced Option)

Direct sowing works best in areas with low weed pressure, excellent drainage, and established host species nearby. It mimics nature, but the conditions have to be spot-on.

• Scarify seeds as above.
• Sow directly into prepared ground, near the base of a young host plant.
• Mark the location—they’ll take their time emerging.
• Protect from grazing animals—young shoots are tender and often targeted by wallabies or rabbits.

This method is less fiddly but harder to control, especially in clay or compacted soils.

🌞 Soil & Position

Quandongs are native to arid and semi-arid zones, so they’re well-suited to:

• Sandy, free-draining soils—avoid clay.
• Full sun—they need warmth and light for healthy growth.
• Low nutrient soils—they prefer poor soils over rich ones.
• Slightly alkaline pH (they’re not fond of acidic conditions).

They’re remarkably drought-tolerant once established but need occasional water early on to get going.

🌿 Care & Maintenance

Once they’re settled in with a host, Quandongs are low-maintenance but do require a bit of attention in the first few years.

• Watering: Light, occasional watering is best. Let the soil dry out between drinks.
• Fertilising: Minimal. You can give the host plant a light feed, but keep fertiliser away from the Quandong.
• Pruning: Trim lightly to encourage branching and airflow.
• Mulching: Use coarse mulch sparingly to suppress weeds without locking in too much moisture.
• Weed control: Essential, especially in the first 1–2 years. Weeds compete with both host and Quandong roots.

🤝 Companion Planting Guide

Remember: Quandong is a root hemiparasite, meaning it partially relies on a host plant for water and nutrients. It’s not a true parasite as it still photosynthesises but it will struggle without a good root connection.

Here are some top hosts and companions:

Host Plant	Why It Works
Acacia acinacea	Fast-growing nitrogen fixer, easy to establish
Myoporum insulare	Hardy coastal shrub, pairs well in sandy soils
Rhagodia spinescens	Low-growing and drought-hardy, common in dry zones
Eremophila spp.	Tough desert natives, ideal for arid climates

Plant your host a few centimetres away, ideally in the same pot if starting in trays. Quandong roots will naturally seek out the host’s roots and graft on.

🍒 Harvesting Quandongs

Quandongs typically fruit 3–5 years after planting. You’ll know they’re ready when the fruit turns a bright, glossy red and starts to soften slightly.

• Timing: Late summer through early autumn
• Method: Twist gently to pick, or let them drop to the ground (they bruise easily, so hand-picking is best)
• Storage: Fruits can be dried, frozen, or used fresh for jams, chutneys, and sauces
• Tip: Harvest with the seed intact if saving for propagation

🐛 Common Issues & Fixes

Here’s a handy table to keep your plants healthy and thriving:

Issue	Symptoms	Fix
No germination	Nothing after 6–12 months	Re-scarify seeds; ensure host is present and viable
Yellowing leaves	Nutrient deficiency or poor host connection	Check host health; add trace minerals to surrounding soil
Root rot	Wilting, black roots	Improve drainage; reduce watering
Pest attack (e.g. aphids)	Sticky residue, curled leaves	Neem spray or soapy water—avoid harsh chemicals
Animal damage	Shoots bitten off	Use tree guards or fencing early on

🌱 Seed Saving Guide

Quandong seeds are as beautiful as the fruit, large, glossy, and full of promise. But saving them takes a little extra effort:

1. Extract seeds from freshly harvested, ripe fruit.
2. Clean thoroughly to remove all pulp. Any leftover fruit can attract mould.
3. Dry naturally in a warm, shady spot for 1–2 weeks.
4. Store in breathable bags or paper envelopes in a cool, dry place.
5. Viability: Seeds remain viable for up to 1 year, but fresher is better.
6. Label with date and known source/parent plant if relevant.

Pro tip: Seeds stored in the fridge (not freezer) can stay viable longer, but humidity control is key.

🌻 Final Thoughts

Quandongs aren’t your average backyard fruit tree but that’s what makes them so special. Growing them is about more than just harvesting bush tucker. It’s about working with nature, understanding plant relationships, and enjoying the challenge of something a little different.

If you’ve ever wanted to grow a fruit that carries the stories of the desert, nourishes wildlife, and looks downright spectacular while doing it then Quandong is your plant.

Start with one. Be patient. Pair it with the right host. And in a few years, you’ll be sharing your own stories of that glossy red fruit that started as a stubborn seed in a tray.
