What To Know
- Gently rub the seeds with sandpaper or a nail file to create small scratches on the seed coat.
- If you live in a climate suitable for Davidson plums, you can sow the seeds directly into the ground.
- If you are sowing multiple seeds in a pot, thin out the seedlings to leave only the strongest one.
The Davidson plum, a unique and flavorful fruit native to Australia, is gaining popularity worldwide. Its tart, tangy flavor and versatility in culinary applications have made it a sought-after ingredient. But did you know that you can grow this exotic fruit from seed? This comprehensive guide will walk you through the process of how to grow Davidson plum from seed, from seed selection to harvesting your own delicious fruits.
Understanding the Davidson Plum
Before we delve into the specifics of propagation, let’s get acquainted with the Davidson plum itself. This small, evergreen tree, scientifically known as *Davidsonia pruriens*, is renowned for its vibrant purple fruit, resembling a miniature plum. The fruit’s skin is thin and waxy, with a flesh that is both tart and sweet, making it perfect for jams, jellies, sauces, and even desserts.
Choosing the Right Seeds
The journey to growing your own Davidson plum starts with selecting the right seeds.
- Freshness is Key: Opt for seeds from ripe, freshly harvested Davidson plums. The fresher the seeds, the higher their viability.
- Seed Extraction: Carefully remove the seeds from the fruit, making sure to keep them intact.
- Cleaning: Gently wash the seeds under running water to remove any remaining pulp or debris.
Preparing the Seeds for Germination
Once you have your seeds, it’s time to prepare them for germination. This involves a process called scarification, which weakens the seed coat and allows water to penetrate more easily.
- Mechanical Scarification: Gently rub the seeds with sandpaper or a nail file to create small scratches on the seed coat.
- Hot Water Treatment: Immerse the seeds in boiling water for 1-2 minutes, followed by an immediate transfer to cold water. This rapid temperature change helps to soften the seed coat.
- Acid Treatment: Soak the seeds in diluted sulfuric acid for 24 hours. This method is particularly effective but requires caution due to the corrosive nature of the acid.
Sowing the Davidson Plum Seeds
After scarification, your seeds are ready for sowing. You can choose to sow them directly into the ground or in pots.
- Direct Sowing: If you live in a climate suitable for Davidson plums, you can sow the seeds directly into the ground. Choose a well-drained spot with full sun to partial shade. Sow the seeds about 1cm deep and cover them with soil.
- Potting: For a controlled environment, sow the seeds in pots filled with a well-draining potting mix. Place the pots in a warm, sunny location and maintain consistent moisture.
Germination and Early Growth
Germination typically takes 4-8 weeks, but it can vary depending on the environmental conditions. Keep the soil consistently moist but not waterlogged. Once the seedlings emerge, provide them with adequate sunlight and nutrients.
- Thinning: If you are sowing multiple seeds in a pot, thin out the seedlings to leave only the strongest one.
- Watering: Water the seedlings regularly, ensuring the soil remains moist but not waterlogged.
- Fertilizing: Feed the seedlings with a balanced fertilizer once they have established a strong root system.
Transplanting the Davidson Plum Seedlings
Once the seedlings have grown to a manageable size, typically around 6-12 months old, they can be transplanted to their permanent location.
- Choosing the Right Spot: Select a sunny spot with well-drained soil. Davidson plums prefer a pH range of 6.0-7.0.
- Digging the Hole: Dig a hole twice the width and depth of the seedling’s root ball.
- Backfilling: Gently place the seedling in the hole, ensuring the root ball is level with the ground. Backfill the hole with soil, taking care not to damage the roots.
- Watering: Water the newly transplanted seedling thoroughly to settle the soil around the roots.
Caring for Your Davidson Plum Tree
Once your Davidson plum tree is established, it requires minimal maintenance.
- Watering: Water your tree regularly, especially during dry periods.
- Fertilizing: Apply a balanced fertilizer once or twice a year to provide essential nutrients.
- Pruning: Prune your tree annually to remove any dead or diseased branches and to maintain its shape.
- Pest and Disease Control: Davidson plums are relatively resistant to pests and diseases, but keep an eye out for potential issues.
Harvesting Your Davidson Plums
After 3-5 years, your Davidson plum tree will start to bear fruit. The fruit ripens in late summer or early autumn, depending on your climate.
- Ripe Fruit: Look for deep purple, almost black, fruits with a slightly soft texture.
- Harvesting: Gently pick the ripe fruits by hand, avoiding any damage to the tree.
The Bottom Line: Embark on Your Davidson Plum Journey
Growing Davidson plum from seed is a rewarding experience. It allows you to witness the magic of nature as a tiny seed transforms into a beautiful tree bearing delicious fruit. With patience, care, and the right techniques, you can enjoy the unique flavors and benefits of this exotic fruit right in your own backyard.
