How to Save Apple Seeds for Planting?
The process of saving apple seeds for planting involves extracting seeds from ripe apples, ensuring they undergo stratification (a period of cold, moist storage) to break dormancy, and then planting them in suitable conditions. Properly executed, this method can yield unique apple trees but remember that the fruit they bear may differ from the parent apple.
Why Save Apple Seeds? The Unexpected Benefits
Saving apple seeds and growing your own apple trees may seem like a purely practical endeavor, but it offers a multitude of benefits. Beyond simply getting “free” apple trees, the process connects you to the natural world and can lead to exciting discoveries.
- Genetic Diversity: Apples don’t grow true-to-seed. This means the resulting tree will be a hybrid, a unique individual with a combination of traits from both parent trees. You might discover an entirely new apple variety!
- Rootstock Development: Even if the fruit is less desirable, the resulting trees can be used as rootstock onto which you can graft scions of known apple varieties. This is a cheaper alternative to buying commercially grown rootstock.
- Self-Sufficiency: Saving seeds and growing your own fruit trees contributes to a more sustainable and self-sufficient lifestyle.
- Educational Value: It’s a fantastic educational project for both children and adults, teaching about plant life cycles, genetics, and the importance of biodiversity.
- Adapting to Local Conditions: Seedlings grown from local apples are often better adapted to the climate and soil conditions of your area.
The Apple Seed Saving Process: Step-by-Step
The process of saving apple seeds involves several key steps to ensure successful germination.
- Choose Ripe Apples: Select fully ripe, healthy apples from varieties you enjoy. Avoid apples from grocery stores, as they may have been treated to prevent sprouting. Heirloom or locally grown apples are ideal.
- Extract the Seeds: Carefully cut the apple open and extract the seeds. Choose plump, brown seeds. Discard any small, white, or shriveled seeds, as they are unlikely to germinate.
- Clean the Seeds: Rinse the seeds thoroughly to remove any pulp or sugar. This prevents mold growth during stratification.
- Dry the Seeds (briefly): Allow the seeds to air dry on a paper towel for just a few hours. Do not let them dry out completely, as this can damage the embryo.
- Stratification (Cold Storage): This is the most crucial step. Place the seeds in a slightly moistened medium such as peat moss, vermiculite, or paper towels inside a sealed plastic bag or container.
- Refrigerate: Store the bag in the refrigerator (around 35-45°F or 2-7°C) for at least 60-90 days. Regularly check the moisture level and add a few drops of water if needed.
- Planting: After stratification, plant the seeds in small pots filled with well-draining potting mix. Plant them about ½ inch deep.
- Provide Light and Water: Keep the soil consistently moist but not waterlogged. Place the pots in a sunny location or under grow lights.
- Transplant: Once the seedlings have developed several sets of true leaves, they can be transplanted into larger pots or directly into the ground in a well-prepared location.
Common Mistakes and How to Avoid Them
Saving apple seeds can be straightforward, but there are some common pitfalls to avoid.
- Using Seeds from Grocery Store Apples: Commercial apples are often hybrids and treated to prevent sprouting. Seeds from these apples are unlikely to germinate or produce viable trees.
- Improper Stratification: Failing to stratify the seeds or not stratifying them for long enough will result in poor germination rates. Ensure at least 60-90 days of cold, moist storage.
- Allowing Seeds to Dry Out Completely: Over-drying can kill the embryo inside the seed.
- Overwatering: Soggy soil can lead to root rot. Use well-draining potting mix and avoid overwatering.
- Lack of Patience: It can take several years for an apple tree grown from seed to produce fruit.
Factors Affecting Apple Tree Fruit Quality When Grown from Seed
Understanding that apple trees grown from seed won’t produce apples identical to the parent tree is crucial. Here’s what influences the fruit’s characteristics:
- Hybridization: Apples are highly heterozygous, meaning they have a diverse mix of genes. Seeds are the result of cross-pollination, so the resulting tree will be a mix of its parents, producing unique fruit.
- Rootstock Influence (if grafted): If you graft a known apple variety onto the seedling rootstock, the fruit will be from the grafted scion, not the rootstock itself. The rootstock, however, can influence vigor, disease resistance, and fruiting precocity.
- Environmental Factors: Sunlight, soil quality, water availability, and climate all play a significant role in determining the final fruit quality.

Frequently Asked Questions (FAQs)
How long will it take for my apple tree to produce fruit if grown from seed?
It typically takes 5-10 years for an apple tree grown from seed to bear fruit. This is significantly longer than grafted trees, which can produce fruit within 2-3 years.
Can I plant apple seeds directly into the ground without stratification?
While it is possible, the germination rate will be very low. Stratification mimics the natural winter conditions that apple seeds require to break dormancy.
What is the best time of year to plant apple seeds?
Plant apple seeds indoors after the stratification period, typically in late winter or early spring.
What kind of soil is best for apple seedlings?
Apple seedlings thrive in well-draining, slightly acidic soil (pH 6.0-7.0).
Do I need to pollinate my apple tree if it grows from seed?
Yes, most apple trees require cross-pollination from another apple variety to produce fruit. You’ll need at least two different apple trees that bloom at the same time in your orchard.
How can I tell if my apple seeds are viable before planting?
Perform a water test. Place the seeds in a glass of water. Seeds that sink are generally viable, while those that float are often not. You can also cut open a few seeds; a healthy seed will have a plump, white interior.
How do I prevent diseases from affecting my apple seedlings?
Ensure good air circulation, avoid overwatering, and consider using organic fungicides if necessary. Select disease-resistant apple varieties as source fruit.
Can I graft a known apple variety onto a seedling apple tree?
Yes, grafting is a common practice. You can graft a scion (a cutting from a desired apple variety) onto the seedling rootstock to ensure the desired fruit characteristics. This also reduces the time to fruiting.
What should I do if my apple seeds start to mold during stratification?
Remove the moldy seeds and replace the stratification medium with fresh, slightly moistened material. Good ventilation is also essential.
How much sunlight do apple seedlings need?
Apple seedlings require at least 6-8 hours of direct sunlight per day to thrive.
Will the apples from my seedling tree taste the same as the apple I got the seeds from?
No, almost certainly not. Due to hybridization, the apples will likely be different, potentially better or worse. It’s part of the fun!
Can I save apple seeds from any apple variety?
Yes, you can save seeds from any apple variety, but be aware of potential patent restrictions on some newer commercially bred varieties. Locally grown or heirloom varieties are usually safe to use.
