How to Plant Tree Seeds: Growing Edible Fruit Trees from Seeds
Benefits of Growing Fruit Trees from Seeds
Starting fruit trees from seeds offers several unique advantages. It’s a cost-effective way to start an orchard, as you won’t need to purchase saplings. Growing trees from seeds also gives you the opportunity to try different varieties and even experiment with unique hybrids. Additionally, watching your fruit trees grow from tiny seeds to full-grown trees can be incredibly satisfying, making it a great project for anyone who enjoys gardening.
Choosing the Right Fruit Seeds
Selecting the right fruit seeds is the first and most important step in planting fruit trees. While many fruits contain seeds, not all seeds will produce fruit trees that are similar to the parent plant. Some fruit seeds, especially those from commercial varieties, are from hybrid plants, meaning they may not grow into a tree that produces the same fruit. However, with proper care and a bit of luck, many seeds can yield fruitful results.
Common edible fruit trees you can grow from seeds include:
- Apple Trees: Apple seeds are relatively easy to sprout, and the resulting trees can produce fruit in as little as 6-10 years.
- Peach Trees: Peach pits can be planted to grow peach trees, which typically bear fruit in 3-5 years.
- Cherry Trees: Cherry seeds can grow into lovely fruiting trees, although the seeds need a period of cold stratification.
- Citrus Trees: Seeds from oranges, lemons, and limes can be planted to grow indoor citrus trees, though they may take a while to bear fruit.
- Pawpaw Trees: Native to North America, pawpaw seeds require cold stratification but can produce delicious tropical-like fruits.
Preparing Tree Seeds for Planting
Each type of fruit seed has unique preparation requirements, but most follow a similar process to encourage germination and growth.
Cleaning the Seeds
After collecting seeds from your chosen fruit, remove any remaining fruit pulp or flesh from the seed. Leftover fruit can cause mold growth or inhibit germination. Rinse the seeds in cool water and let them dry on a paper towel.
Cold Stratification
Most fruit tree seeds require a period of cold stratification to simulate winter conditions, which breaks seed dormancy and encourages germination.
- Place the cleaned seeds in a damp paper towel or plastic bag.
- Store them in the refrigerator for 1-3 months, depending on the seed variety. Apples and cherries, for example, require around 60-90 days.
- Check the seeds periodically to ensure they remain moist but not overly wet.
Some seeds, like those from tropical fruits (such as citrus), do not need cold stratification. Research the specific requirements for each type of seed to ensure optimal germination.
Scarification for Hard Seeds
Some seeds, like peaches and cherries, have hard outer shells that can benefit from scarification. Scarification involves lightly nicking or sanding the seed coat to allow water and oxygen to penetrate the seed more easily.
- Use a small file or sandpaper to lightly abrade the seed coat.
- Avoid damaging the inner seed, as this can harm the embryo.
Soaking
For seeds with thick coats, soaking can also help encourage germination. Place the seeds in a bowl of room-temperature water and allow them to soak for 24-48 hours. This step is particularly useful for peach, cherry, and plum seeds.
Planting Tree Seeds
Once the seeds have been cleaned, stratified, and prepared, they’re ready to be planted.
Choosing the Right Container
Start by selecting a container with good drainage holes, as fruit tree seeds need well-draining soil to avoid root rot. For seeds that require deep planting, choose a deeper container or pot. Small pots or seed trays are ideal for starting seeds indoors.
Soil Preparation
Use a high-quality potting mix that drains well, such as a mix with peat, perlite, and a small amount of organic compost. Avoid using heavy garden soil, which can become compacted and hinder root growth.
Planting Depth
Plant the seeds at a depth of about twice their size. For example, apple seeds should be planted about ½ inch deep, while larger seeds like peach pits may need to be planted around 1 inch deep.
Watering After Planting
After planting, water the soil lightly but thoroughly, ensuring that the soil is evenly moist but not waterlogged. Avoid overwatering, as this can lead to mold growth or rot.
Light and Temperature
Place the containers in a warm, sunny location where they receive indirect light. Ideal germination temperatures range between 65°F and 75°F, depending on the type of fruit tree.
Cover the containers with a plastic bag or clear dome to create a greenhouse effect and maintain consistent moisture and warmth. Remove the cover once the seedlings begin to sprout to avoid mold growth.
Caring for Young Fruit Tree Seedlings
As the seeds germinate and seedlings begin to grow, consistent care will help them thrive.
Watering
Continue to keep the soil evenly moist but not soggy. Watering deeply and infrequently encourages deep root growth, which is beneficial as the trees mature.
Thinning
Once the seedlings have developed a few sets of leaves, thin them out to avoid overcrowding. Remove the weaker seedlings, leaving only the strongest ones in each container.
Fertilizing
Young seedlings don’t require much fertilizer, but once they’re about 4-6 inches tall, you can apply a diluted balanced fertilizer to promote growth. Use a gentle, organic fertilizer to avoid burning the young plants.
Transplanting to Larger Containers
When the seedlings have outgrown their initial containers, transplant them to larger pots. Transplanting helps prevent root-bound plants and encourages healthy root development.
Hardening Off and Transplanting Outdoor
Once your seedlings are strong enough, you can transplant them to their final outdoor location.
Hardening Off
To prevent transplant shock, gradually introduce the seedlings to outdoor conditions by hardening them off.
- Place the seedlings outside in a shaded area for a few hours each day, gradually increasing exposure to sunlight and outdoor temperatures.
- Over the course of a week, gradually increase their time outdoors until they can stay outside all day.
Choosing a Planting Site
Select a site that receives full sun, with well-draining soil and good air circulation. Avoid areas with heavy clay or compacted soil, as this can impede root growth and water drainage.
Planting the Seedlings
Dig a hole twice the width and depth of the root ball. Gently place the seedling in the hole, fill with soil, and water thoroughly. Mulch around the base of the tree to retain moisture and regulate soil temperature.
Ongoing Care for Fruit Trees
Once planted, fruit trees require regular care to ensure they grow healthy and produce fruit.
Watering
Young fruit trees need consistent watering to establish deep roots. Water deeply, especially during dry periods, ensuring the soil around the roots stays moist.
Pruning
Prune young fruit trees to establish a strong framework for future growth. Remove any damaged or crossed branches, and shape the tree to encourage airflow and light penetration.
Fertilizing
Apply a balanced fertilizer each spring to support growth and fruit production. Avoid heavy nitrogen applications, as this can lead to excessive leaf growth at the expense of fruit development.
Pest and Disease Control
Keep an eye out for pests and diseases, which can damage young fruit trees. Common issues include aphids, fungal infections, and caterpillars. Use organic pest control methods like neem oil or insecticidal soap, and practice good sanitation to minimize disease risks.
Patience and Expected Timeline for Fruit Production
Growing a fruit tree from seed requires patience, as it can take several years before the tree matures and produces fruit. Here are some general timelines for popular fruit trees:
- Apple Trees: 6-10 years to bear fruit
- Peach Trees: 3-5 years
- Cherry Trees: 4-7 years
- Citrus Trees: 5-15 years, depending on the variety
- Pawpaw Trees: 4-8 years
While it may take a few years before your fruit trees bear fruit, the satisfaction of growing a tree from seed makes the wait worthwhile.
Frequently Asked Questions
Can I grow fruit trees from any seed?
Not all fruit seeds will grow true to the parent plant. Commercial fruit varieties are often hybrids, meaning the offspring may differ from the original fruit. However, many seeds can still produce healthy trees.
