This guide will walk you through the journey of how to grow kakadu plum, from seed to harvest, empowering you to cultivate this unique and rewarding fruit.
Understanding the Kakadu Plum
The Kakadu plum, scientifically known as *Terminalia ferdinandiana*, is a small, deciduous tree native to northern Australia. It thrives in hot, arid conditions and is known for its resilience. The fruit, which ripens between June and August, is a powerhouse of nutrients, boasting the highest natural vitamin C content of any fruit in the world.
Choosing the Right Location
The first step in your kakadu plum journey is selecting the perfect spot in your garden. Remember, this tree loves the sun! Aim for a location that receives at least six hours of direct sunlight daily.
Consider these factors:
- Soil Type: Kakadu plums prefer well-drained, sandy soil with a slightly acidic pH (between 5.5 and 6.5).
- Drainage: Good drainage is crucial to prevent root rot. Avoid planting in areas prone to waterlogging.
- Shelter: While the tree is drought-tolerant, it benefits from some protection from strong winds.
Planting Your Kakadu Plum
Once you’ve chosen your ideal spot, it’s time to plant your kakadu plum. You can start with seeds, cuttings, or purchase a young sapling from a reputable nursery.
From Seed:
- Scarification: Kakadu plum seeds have a hard outer coat that needs to be scarified to aid germination. This can be done by soaking the seeds in hot water (around 80°C) for 24 hours or by rubbing them with sandpaper.
- Sowing: Sow the seeds in a well-draining seed-raising mix, keeping them moist but not waterlogged.
- Germination: Germination can take several weeks, so be patient.
From Cuttings:
- Take cuttings: Cuttings should be taken from healthy, mature branches in late winter or early spring.
- Preparation: Dip the cut ends in rooting hormone and plant them in a well-draining potting mix.
- Rooting: Keep the cuttings in a warm, humid environment and ensure they receive indirect sunlight. Rooting can take several weeks.
From Sapling:
- Preparation: Dig a hole twice the width and depth of the sapling’s root ball.
- Planting: Place the sapling in the hole, ensuring the root ball is at ground level. Backfill with soil, gently firming it around the roots.
- Water: Water the sapling thoroughly after planting.
Providing Essential Care
Once your kakadu plum is established, consistent care will help it thrive.
- Watering: Water your tree regularly, especially during dry periods. However, avoid overwatering, as this can lead to root rot.
- Fertilizing: Apply a balanced fertilizer, such as a slow-release granular fertilizer, twice a year, once in spring and once in autumn.
- Mulching: Mulch around the base of the tree with organic matter like bark chips or compost to retain moisture and suppress weeds.
- Pruning: Prune your kakadu plum in late winter or early spring to remove any dead, diseased, or crossing branches.
