What To Know
- This involves a process called scarification, which weakens the seed coat and helps the seed germinate.
- You can scarify the seeds by nicking the seed coat with a sharp knife or using sandpaper to gently rub the surface.
- Apply a balanced fertilizer to the tree in spring and summer, following the instructions on the fertilizer packaging.
The Burdekin plum, also known as the “native plum” or “wild plum,” is a unique and delicious fruit native to Australia. Its sweet, juicy flesh and vibrant purple color make it a popular choice for jams, chutneys, and even wine. If you’re looking to add this exotic fruit to your garden, you might be wondering – how to grow burdekin plum from seed?
This comprehensive guide will walk you through the process of growing Burdekin plums from seed, from preparing the seed to nurturing the young tree. We’ll cover everything from seed collection to planting, ensuring you have all the information you need to cultivate your own Burdekin plum orchard.
Seed Collection and Preparation
The first step in growing Burdekin plum from seed is collecting the seeds. This is best done after the fruit has ripened, usually in late summer or early autumn. Here’s how to do it:
1. Select Ripe Fruit: Choose ripe, healthy Burdekin plums with vibrant purple skin and a slightly soft texture.
2. Extract the Seeds: Carefully cut the fruit open and remove the seeds. Each fruit contains one to three seeds.
3. Clean the Seeds: Wash the seeds thoroughly to remove any remaining pulp. Let them dry completely.
Now that you have your seeds, you need to prepare them for planting. This involves a process called scarification, which weakens the seed coat and helps the seed germinate:
1. Scarification: You can scarify the seeds by nicking the seed coat with a sharp knife or using sandpaper to gently rub the surface.
2. Soaking: After scarification, soak the seeds in warm water for 24 hours. This will further soften the seed coat and promote germination.
Sowing the Seeds
Once the seeds have been scarified and soaked, it’s time to sow them. Here’s what you need to do:
1. Choose a Pot: Select a pot with good drainage and a depth of at least 10 cm (4 inches).
2. Fill with Seed-Starting Mix: Use a well-draining seed-starting mix or a blend of potting soil and perlite.
3. Sow the Seeds: Sow the seeds about 1 cm (0.5 inches) deep and space them 5 cm (2 inches) apart.
4. Water Gently: Water the seeds thoroughly but gently, ensuring the soil is moist but not waterlogged.
5. Place in a Sunny Spot: Place the pot in a sunny location, preferably outdoors.
Germination and Early Care
Burdekin plum seeds typically take 4 to 6 weeks to germinate. During this time, it’s important to maintain optimal conditions for the seedlings:
1. Keep the Soil Moist: Water the seedlings regularly, ensuring the soil remains moist but not soggy.
2. Protect from Frost: If you live in a region with frost, protect the seedlings from cold temperatures.
3. Thin Out Seedlings: Once the seedlings have a few true leaves, thin them out, leaving the strongest seedling in each pot.
Transplanting the Seedlings
Once the seedlings have reached a height of 15-20 cm (6-8 inches) and have developed a strong root system, they can be transplanted outdoors.
1. Choose a Sunny Location: Select a sunny spot in your garden with well-drained soil.
2. Prepare the Planting Hole: Dig a planting hole twice the width and depth of the seedling’s root ball.
3. Plant the Seedling: Gently remove the seedling from its pot and place it in the planting hole. Backfill the hole with soil, ensuring the root ball is level with the ground.
4. Water Thoroughly: Water the newly planted seedling deeply.
Ongoing Care and Maintenance
Once your Burdekin plum tree is established, it requires regular care and maintenance to thrive. Here’s what you need to do:
1. Watering: Water the tree deeply during dry periods, especially during the first year after planting.
2. Fertilizing: Apply a balanced fertilizer to the tree in spring and summer, following the instructions on the fertilizer packaging.
3. Pruning: Prune the tree in late winter or early spring to remove any dead, diseased, or crossing branches.
4. Pest and Disease Control: Monitor the tree for pests and diseases, and take appropriate action if necessary.
Harvesting Your Burdekin Plums
Your Burdekin plum tree will start producing fruit after 3 to 5 years. The fruit will ripen in late summer or early autumn. You’ll know the plums are ready to harvest when they are soft to the touch and have a deep purple color.
1. Harvesting: Pick the plums by hand, gently twisting them off the branch.
2. Storage: Store the harvested plums in the refrigerator for up to a week.
