By the end of this article, you will be ready to start your own pecan adventure.

How to Prepare Pecan Seeds for Planting

The first step in growing pecan trees from seed is to prepare the seeds for planting. Pecan seeds are actually the nuts that you eat, which contain a kernel (the edible part) inside a hard shell. The shell protects the kernel from drying out and also prevents it from germinating until the right conditions are met.

Pecan seeds need to undergo stratification, a process of exposing them to cold and moist conditions for a certain period of time, before they can germinate. Stratification breaks the dormancy of the seeds and stimulates them to sprout when they are planted.

To stratify pecan seeds, you will need:

  • Fresh pecans that have not been roasted or salted
  • A plastic bag or container with a lid
  • A damp paper towel or peat moss
  • A refrigerator

Here are the steps to stratify pecan seeds:

  1. Collect fresh pecans from a local source or buy them online. Make sure they have not been roasted or salted, as this will kill the seeds. You can also use store-bought pecans that are labeled as raw or natural, but they may have lower germination rates.
  2. Crack open the shells carefully with a nutcracker or a hammer. Try not to damage the kernels inside. You can also soak the shells in water for a few hours to make them easier to crack.
  3. Remove the kernels from the shells and inspect them for any signs of mold, rot, or insect damage. Discard any bad kernels.
  4. Wrap the kernels in a damp paper towel or peat moss and place them in a plastic bag or container with a lid. Make sure the paper towel or peat moss is moist but not soggy.
  5. Label the bag or container with the date and store it in the refrigerator for at least 90 days. Check on them occasionally and add more water if needed.
  6. After 90 days, take out the bag or container and check if the kernels have sprouted. You should see a small root emerging from one end of each kernel. If not, leave them in the refrigerator for another 30 days or until they sprout.

Some tips and warnings on how to stratify pecan seeds:

  • The best time to stratify pecan seeds is in late fall or early winter, so that they are ready for planting in spring.
  • The ideal temperature for stratification is between 1°C and 4°C (34°F and 40°F). Do not freeze the seeds, as this will kill them.
  • The ideal moisture level for stratification is between 30% and 40%. Do not let the seeds dry out or get too wet, as this will reduce their germination rates.
  • The ideal number of seeds to stratify is between 10 and 20. Do not overcrowd the seeds, as this will increase the risk of mold and rot.
  • You can also stratify pecan seeds in the ground, by burying them about 10 cm (4 inches) deep in a well-drained spot that gets some shade. Cover them with mulch or leaves to protect them from frost and animals. However, this method is less reliable and more prone to failure than stratifying them in the refrigerator.

How to Plant and Germinate Pecan Seeds

how to grow pecan trees from seed

The second step in growing pecan trees from seed is to plant and germinate the seeds. Pecan seeds can be planted in pots or containers and need well-drained soil, adequate water, and sunlight to sprout and grow.

To plant and germinate pecan seeds, you will need:

  • Stratified pecan seeds with sprouted roots
  • Pots or containers with drainage holes
  • Potting soil or garden soil mixed with compost or sand
  • Water
  • A sunny spot or a greenhouse

Here are the steps to plant and germinate pecan seeds:

  1. Fill the pots or containers with soil, leaving some space at the top. Make sure the soil is moist but not soggy.
  2. Make a hole in the center of each pot or container, about 5 cm (2 inches) deep.
  3. Place one pecan seed in each hole, with the root pointing down and the tip slightly above the soil surface. Do not bury the seed too deep or too shallow, as this will affect its growth.
  4. Cover the seed lightly with soil and press it gently to firm it.
  5. Water the pots or containers well, but do not overwater them. Keep the soil moist but not wet, as this will prevent rotting and drowning.
  6. Place the pots or containers in a sunny spot or a greenhouse, where they can get at least 6 hours of direct sunlight per day. You can also use artificial lights if needed.
  7. Wait for the seeds to germinate, which can take anywhere from 2 weeks to 2 months, depending on the temperature and moisture levels. You should see a green shoot emerging from the soil, followed by two cotyledons (seed leaves) and then true leaves.

Some tips and tricks on how to plant and germinate pecan seeds:

  • The best time to plant pecan seeds is in spring, after the last frost, when the soil is warm and moist.
  • The ideal temperature for germination is between 21°C and 27°C (70°F and 80°F). Avoid exposing the seeds to extreme heat or cold, as this will slow down or stop their germination.
  • The ideal pH level for germination is between 6.0 and 6.5. You can use a pH tester or a litmus paper to check the acidity or alkalinity of your soil. You can also adjust the pH level by adding lime (to raise it) or sulfur (to lower it).
  • You can use any type of pot or container that has drainage holes, such as plastic, clay, metal, or wood. However, avoid using metal pots or containers that can rust or corrode, as this will harm the seeds and seedlings.
  • You can use any type of soil that is well-drained, fertile, and loose, such as potting soil or garden soil mixed with compost or sand. However, avoid using soil that is too heavy, compacted, salty, or contaminated, as this will hinder the growth of the seeds and seedlings.

How to Care for Pecan Seedlings

The third step in growing pecan trees from seed is to care for the pecan seedlings. Pecan seedlings can be transplanted to larger pots or containers and need regular care and maintenance, such as watering, fertilizing, pruning, and pest control.

To care for pecan seedlings, you will need:

  • Pecan seedlings with at least four true leaves
  • Larger pots or containers with drainage holes
  • Potting soil or garden soil mixed with compost or sand
  • Water
  • Fertilizer
  • Pruning shears
  • Insecticidal soap or neem oil
  • A sunny spot or a greenhouse

Here are the steps to care for pecan seedlings:

  1. Transplant the pecan seedlings to larger pots or containers when they have at least four true leaves, which are the leaves that appear after the cotyledons. To transplant, gently loosen the soil around the roots and lift the seedling out of its original pot or container. Place it in a new pot or container that is at least twice as large as the previous one and fill it with soil, leaving some space at the top. Make a hole in the center of the new pot or container and place the seedling in it, with the root ball slightly below the soil surface. Cover the root ball lightly with soil and press it gently to firm it.
  2. Water the transplanted seedlings well, but do not overwater them. Keep the soil moist but not wet, as this will prevent rotting and drowning.
  3. Fertilize the transplanted seedlings once a month with a balanced fertilizer, such as 10-10-10 or 20-20-20, following the instructions on the label. Do not overfertilize them, as this will burn their roots and leaves.
  4. Prune the transplanted seedlings once a year in late winter or early spring, before they start growing new leaves. To prune, cut off any dead, diseased, or damaged branches and leaves with pruning shears. You can also trim off any branches that are too long, too crowded, or crossing each other. Pruning will improve the shape, health, and productivity of your pecan trees.
  5. Protect the transplanted seedlings from pests and diseases, such as aphids, mites, caterpillars, borers, fungus, and bacteria. To prevent pests and diseases, keep your pecan trees clean and healthy, remove any fallen leaves and debris from the pots or containers, and avoid injuring or wounding your pecan trees. To treat pests and diseases, spray your pecan trees with insecticidal soap or neem oil, following the instructions on the label. Do not use any harsh chemicals or pesticides that can harm your pecan trees or yourself.
  6. Place the transplanted seedlings in a sunny spot or a greenhouse, where they can get at least 6 hours of direct sunlight per day. You can also use artificial lights if needed.

Some tips and tricks on how to care for pecan seedlings:

  • The best time to transplant pecan seedlings is in spring or summer, when the weather is warm and sunny.
  • The ideal temperature for growth is between 21°C and 32°C (70°F and 90°F). Avoid exposing your pecan trees to extreme heat or cold, as this will stunt their growth or kill them.
  • The ideal pH level for growth is between 6.0 and 6.5. You can use a pH tester or a litmus paper to check the acidity or alkalinity of your soil. You can also adjust the pH level by adding lime (to raise it) or sulfur (to lower it).
  • You can use any type of pot or container that has drainage holes, such as plastic, clay, metal, or wood. However, avoid using metal pots or containers that can rust or corrode, as this will harm your pecan trees.
  • You can use any type of soil that is well-drained, fertile, and loose, such as potting soil or garden soil mixed with compost or sand. However, avoid using soil that is too heavy, compacted, salty, or contaminated, as this will hinder the growth of your pecan trees.

How to Graft Pecan Trees

The fourth step in growing pecan trees from seed is to graft them. Grafting is a technique of joining two parts of different plants together so that they grow as one. Grafting can improve the quality and yield of your pecan trees, by combining a scion (a branch or twig) from a desired cultivar (a variety of a plant that has been selected and cultivated for its desirable characteristics) to a rootstock (a seedling or a mature tree that provides the roots and the lower stem).

To graft pecan trees, you will need:

  • Pecan trees that are at least two years old and have a stem diameter of at least 1 cm (0.4 inches)
  • Scions from a desired cultivar that have at least three buds and are about 15 cm (6 inches) long
  • A grafting knife or a sharp knife
  • A grafting tape or a rubber band
  • A grafting wax or a petroleum jelly
  • A pruning saw or a lopper
  • A sunny spot or a greenhouse

Here are the steps to graft pecan trees:

  1. Choose the best time and method for grafting. The best time for grafting is in late winter or early spring, before the buds start to swell. The best method for grafting is the whip-and-tongue method, which involves making matching cuts on both the scion and the rootstock and fitting them together.
  2. Cut off the top of the rootstock with a pruning saw or a lopper, leaving about 1 m (3 feet) of stem above the ground. Make sure the cut is smooth and straight.
  3. Make a slanting cut on the rootstock, about 5 cm (2 inches) below the top cut, with a grafting knife or a sharp knife. The cut should be about 4 cm (1.5 inches) long and go halfway through the stem.
  4. Make a vertical cut on the rootstock, starting from the middle of the slanting cut and going downward, with a grafting knife or a sharp knife. The cut should be about 2 cm (0.8 inches) long and create a tongue-like flap on the stem.
  5. Cut off the bottom of the scion with a grafting knife or a sharp knife, leaving about 15 cm (6 inches) of twig above the lowest bud. Make sure the cut is smooth and straight.
  6. Make a slanting cut on the scion, about 5 cm (2 inches) above the bottom cut, with a grafting knife or a sharp knife. The cut should be about 4 cm (1.5 inches) long and go halfway through the twig.
  7. Make a vertical cut on the scion, starting from the middle of the slanting cut and going upward, with a grafting knife or a sharp knife. The cut should be about 2 cm (0.8 inches) long and create a tongue-like flap on the twig.
  8. Fit the scion and the rootstock together, matching their cuts and tongues. Make sure their cambium layers (the thin green layers under the bark) are aligned and in contact with each other.
  9. Wrap the graft union (the point where the scion and the rootstock join) with a grafting tape or a rubber band, starting from below and going upward, overlapping each turn by half. Make sure the tape or band is tight and secure, but not too tight to strangle or damage the graft.
  10. Cover the graft union with a grafting wax or a petroleum jelly, sealing any gaps or cracks that might expose the cambium layers to air or moisture. This will prevent drying out and infection of the graft.
  11. Place the grafted pecan tree in a sunny spot or a greenhouse, where it can get at least 6 hours of direct sunlight per day. You can also use artificial lights if needed.

Some tips and tricks on how to graft pecan trees:

  • The best source of scions is from healthy and productive pecan trees that have similar characteristics to your rootstocks, such as size, shape, growth rate, disease resistance, and nut quality.
  • The best time to collect scions is in late fall or early winter, when they are dormant and have no leaves. You can store them in plastic bags in the refrigerator until you are ready to use them.
  • The ideal temperature for grafting is between 10°C and 18°C (50°F and 65°F). Avoid grafting when it is too hot or too cold, as this will affect the healing and survival of your grafts.
  • The ideal moisture level for grafting is between 60% and 80%. Avoid grafting when it is too dry or too wet, as this will cause dehydration or rotting of your grafts.
  • You can use any type of grafting knife or sharp knife that is clean and sharp, but avoid using serrated or blunt knives, as this will damage your scion and rootstock.
  • You can use any type of grafting tape or rubber band that is flexible and elastic, but avoid using rigid or brittle ones, as this will break or cut your grafts.
  • You can use any type of grafting wax or petroleum jelly that is sticky and waterproof, but avoid using hard or runny ones, as this will crack or drip off your grafts.

How to Harvest and Store Pecans

The fifth and final step in growing pecan trees from seed is to harvest and store the pecans. Pecan trees can be harvested when the nuts are ripe and ready, usually in autumn, and need to be dried, shelled, stored, and enjoyed.

To harvest and store pecans, you will need:

  • Pecan trees that are at least five years old and have a trunk diameter of at least 10 cm (4 inches)
  • A ladder or a pole
  • A bucket or a basket
  • A tarp or a sheet
  • A nutcracker or a hammer
  • A colander or a sieve
  • A cloth or a paper towel
  • An airtight container or a freezer bag
  • A cool and dry place or a freezer

Here are the steps to harvest and store pecans:

  1. Choose the best time and method for harvesting. The best time for harvesting is in autumn, when the nuts are mature and ready to fall. The best method for harvesting is to shake the branches or hit them with a pole or a ladder, and collect the fallen nuts in a bucket or a basket.
  2. Spread the harvested nuts on a tarp or a sheet in a sunny spot, where they can dry for about two weeks. Turn them occasionally and remove any debris or damaged nuts.
  3. Crack open the shells carefully with a nutcracker or a hammer. Try not to damage the kernels inside. You can also soak the shells in water for a few hours to make them easier to crack.
  4. Remove the kernels from the shells and inspect them for any signs of mold, rot, or insect damage. Discard any bad kernels.
  5. Rinse the kernels with water and drain them in a colander or a sieve. Pat them dry with a cloth or a paper towel.
  6. Store the kernels in an airtight container or a freezer bag, labeled with the date and variety. Keep them in a cool and dry place, such as a pantry or a cellar, where they can last for up to six months. Alternatively, you can freeze them in a freezer, where they can last for up to two years.
  7. Enjoy your pecans raw or roasted, plain or salted, as snacks or ingredients for baking, cooking, or making candy.

Some tips and tricks on how to harvest and store pecans:

  • The best way to tell if your pecans are ripe and ready is to look at their husks (the green outer coverings). If they are split open and reveal the brown shells inside, they are ready to harvest.
  • The best way to tell if your pecans are dry and ready is to shake them gently. If they rattle inside their shells, they are dry enough to store.
  • The best way to tell if your pecans are fresh and good is to taste them. If they are sweet and crunchy, they are fresh and good. If they are bitter and rancid, they are old and bad.
  • You can also roast your pecans before storing them, which will enhance their flavor and extend their shelf life. To roast your pecans, spread them on a baking sheet in a single layer and bake them in an oven at 180°C (350°F) for about 15 minutes, stirring occasionally.
