If you enjoy eating almonds or if you like the look of almond trees, then you may wish to grow your own almond tree from a seed. Keep in mind that an almond tree grown from a seed may not produce almonds of the same quality as the seed you planted since many almonds are hybrids and they do not always grow true from seeds. But whether you are sprouting an almond to produce a tree or for possible rootstock, growing an almond tree from seeds can be very satisfying. Almond trees grow best in USDA hardiness zones five through nine.
Purchase raw, unprocessed almonds from a health food store or from another source that sells totally unprocessed almonds.
Remove the almonds from the shell carefully, using a nut cracker, without damaging the nut itself.
Discard the shells and place the nuts in a bowl of water, allowing them to soak overnight.
Spread several layers of paper towels in a shallow baking pan (a cookie sheet is perfect) and dampen the towels but do not allow water to puddle in the pan.
Spread your almonds on the damp paper towel and then cover with a single sheet of paper towel. Spray the top layer of paper towel until it is thoroughly damp, but again do not puddle water in the pan.
Place the pan in a sunny and warm room (65 to 75 F) but not in direct sunlight. Keep the top paper towel moist, spraying it with water whenever it begins to dry out. Your almond seeds should begin to sprout within seven days. The young almond seedlings will push through the top damp paper towel unaided.
Allow the almond plants to get approximately 1-inch high (approximately seven to 10 days after sprouting) and then carefully transplant them into growing pots (with drain holes) filled with potting soil. Do not remove the two halves of the almond that will still be attached to your seedling. No fertilizer is required at this point. Keep the soil damp, but not soggy, and place your seedlings where they can receive several hours of direct sunlight per day. Keep them warm at night (65 to 70 F) until they have reached 5 to 6 inches in height. Now you will transplant to the ground.
Plant your seedlings outdoors in January or February or as soon as all danger of frost has passed in your area. Choose a sunny, well-drained location. Dig a hole twice as deep and twice as wide as the growing pot. Place the seedling in the hole and gently press the soil around it with your fingers, being careful not to damage the young roots. Plant no deeper than the plant was growing in the pot. Water the soil well, and keep slightly damp but do not overwater.
