Almond trees grow well in warm areas like in California, which is the world leader in almond production, according to the Almond Board of California. The almond tree blooms in February or March, sprouts leaves and then produces a greenish fruit that looks like a peach. Referred to as a hull, the fruit will harden and split, displaying the almond shell in the core of the hull. To increase your chances of success growing an almond tree from seed, start with almonds in the shell rather almonds that have the shell removed.
Fill a container with tap water and put the almonds in in the container. (A baking bowl or cooking pot can be used.) Start with at least 12 almonds because not all will germinate. Leave the almonds soaking in the water for at least eight hours and then drain them.
Partially crack the almond shell to expose the nut inside. Place a damp paper towel or damp sphagnum moss in an airtight container, add the partially cracked nuts and then seal the container.
Place the container in the refrigerator for two to three months. Check the container every week to ensure moisture still is inside.
Fill flowerpots with potting soil; small pots, with holes in the bottom for drainage, can be used. Plant the seeds outside after the last frost as an alternative to putting it in a pot if you live in an area with mild winters. Choose a sunny location that drains well.
Work the soil down and across at least six inches for each nut. Press the nut about one inch into the soil. Several nuts can be inserted into each flowerpot or planting container because not all may sprout. Water the seeds.
Place the pots in a warm, sunny location, which may be outdoors if danger of frost has past. Bring the pots indoors in early fall if you live in a cold-winter area.
Water when the soil feels dry about one and-a-half to two inches down--or about once a week for in-house plantings. If the seeds are planted outside in the ground, water every seven to 10 days if it hasn't rained. Outdoor pots may need more frequent watering.
Transplant nuts that sprout to a final location (if necessary) after they are about 18 inches tall.
