Selecting high-quality seeds when growing hazelnuts from seed. Choosing between wild and cultivated hazelnuts can impact growth. Cultivated varieties often yield more predictable results in size and nut production. Wild hazelnuts contribute to genetic diversity.
You should source seeds from a reputable supplier. Ensures they are untreated and suitable for germination. Alternatively, foraging seeds from native plants nearby. You can grow trees naturally adapted to local conditions. This increases their chances of success.
Examine each seed’s firmness and appearance to check seed viability. Healthy seeds are typically full without visible damage or cracks.
A simple float test can also help: place seeds in water, discarding any that float. Because they may be hollow or damaged. Choosing strong, viable seeds is a foundational step to cultivating thriving hazelnut trees from seed.
Hazelnut seeds have a natural dormancy. They won’t germinate without specific conditions mimicking winter. To break this dormancy, hazelnut seeds require a cold stratification period. This replicates winter’s chill and triggers germination.
Put the seeds in a damp paper towel. Seal them in a plastic bag. Place this setup in the refrigerator. Keep the temperature 33°F-41°F. This simulates natural winter conditions.
Check periodically to ensure the seeds remain slightly damp. This process typically takes 3-6 months. The seed will have adequate time to prepare for growth.
Hazelnuts prefer well-draining soil with compost. Waterlogging soil can lead to root rot. It also provides the necessary nutrients for robust tree development. Make sure the soil pH is 6-7.
Hazelnut trees require full sun for the best yields. Ample sunlight encourages flowering and nut development. They should receive six hours of direct sunlight each day.
These trees can grow quite large. They can reach 10-20 feet in height and wide. Space trees 15-20 feet apart. This spacing promotes good air circulation and reduces disease. Each tree can thrive without competition for resources.
These seeds can take several months to sprout. Begin by choosing nursery plastic pots with good drainage. Filling them with a suitable soil mix. A loamy soil with peat works well. It retains moisture while allowing excess water to drain. This can prevent root rot and provide a nourishing base for hazelnut seedlings. Alternatively, mix equal parts of garden soil, peat and sand. This creates a blend that promotes strong root development.
Plant each hazelnut seed 1-2 inches deep. Place one seed per pot when growing hazelnut trees from seed. This can avoid overcrowding. Space them 6 inches apart if planting multiple seeds in a garden bed. You will need to transplant them to a larger area once they grow.
Maintaining consistent moisture is key for germination. Water the pots carefully. Hazelnut seeds need steady hydration during the germination period. So check the soil regularly and water as needed.
Hazelnut seeds are slow to germinate. Generally, they require a period of 6 to 12 months to sprout, especially after the cold stratification process. Place the 25 gallon tree pot in a warm, bright location to encourage germination. You should avoid direct, harsh sunlight. It can dry out the soil too quickly.
Thin out weaker sprouts once the seedlings emerge. This can give stronger ones room to grow. These young plants are delicate at first. So continue providing consistent care until transplant.
Move them to a permanent location when seedlings are 6-12 inches tall. This is typically after 6-12 months of germination. Timing the transplanting process is essential. Late spring to early summer is ideal. The seedlings can acclimate before summer.
Place the seedlings outside for a few hours each day. Gradually increasing their exposure to sunlight for 1-2 weeks. This method helps reduce transplant shock. The seedlings will suit their new environment soon.
Choose a sunny location when transplant. Dig a hole twice as wide as the root ball. But make sure it is just as deep. The top of the root ball should be level with the soil.
Carefully remove the seedling from its pot. Take care not to damage the roots. Place it in the prepared hole. Fill in with soil, gently patting down to remove air pockets. Then, water thoroughly.
Regular maintenance to promote healthy growth. Water the seedlings consistently, especially in dry conditions.
Add mulch around the base of the trees. This can retain moisture and suppress weeds. It can also regulate soil temperature. A layer of organic mulch is ideal. For example, wood chips or straw.
You should approach fertilization cautiously. It’s best to wait until the seedlings are established. This is typically after their first year. Applying a balanced fertilizer in early spring. This promotes healthy growth without overwhelming the young plants.
During the first few years, focus on removing any dead and damaged branches. Shaping the tree to encourage a strong structure. Selective pruning as the trees mature. This can help improve airflow and sunlight penetration. Pruning can also reduce disease and enhance nut production.
Aphids are small insects. They feed on sap. This weakens the tree and potentially spreads viruses. Organic solutions can manage aphids without harming beneficial insects. For example, insecticidal soaps and neem oil.
Caterpillars defoliate branches and impacting growth. Handpicking them off young trees can be effective. Apply a natural insecticide if the infestation is significant. For example, Bacillus thuringiensis.
Eastern filbert blight is a fungal disease. It causes cankers on branches and can severely impact tree health. To manage this, prune and remove any infected branches promptly. Apply a fungicide if necessary. Regularly monitoring trees for early signs can help control its spread.
Regularly inspect trees for any signs. You should maintain good garden hygiene. Remove any fallen debris that could harbor pests or fungi. These proactive steps help maintain the health of hazelnut trees. This ensures a stronger, more resilient yield over time.
Hazelnut trees can take 5-7 years to start producing nuts. They will develop healthy foliage and branches. The formation of catkins are the tree’s flower structures. These will later produce nuts.
As the trees mature, you may notice small green husks forming in late spring and early summer. This indicates that nut development is underway. The husks will turn brown in late summer to early fall. Harvest when the nuts start to drop from the tree.
Gently shake the branches. Then, collect fallen nuts from the ground. You should process the nuts quickly to prevent spoilage. Remove the husks and store them in a cool, dry place.
