The hawthorn tree is also commonly referred to as the thornapple. It is a deciduous tree that can grow 10 to 16 feet tall. They are easy to grow and are most commonly found in the lower half of the United States. The tree blooms in the spring with white flowers and produces a small red fruit. It can take over a year for hawthorn seeds to germinate. The seeds must be fresh and should be planted in the fall.
Harvest the berries from a hawthorn tree in the fall. The berried should be mashed so the seeds can be extracted. You can use a potato masher to mash the fruit from the seed. Clean all traces off of the berry to remove any pulp.
Cover the seeds with cool water, and soak them overnight in a small bowl.
Mix equal parts of peat-free compost and horticulture sand. Fill a 4- to 6-inch pot approximately three-fourths of the way full with the mixture.
Dig a small hole about an inch deep into the sand. Place the seed inside, and cover it with the sand mix.
Cover the pot with cheesecloth or chicken wire to prevent birds from digging the seeds. Place the pot outside in a shady location.
Water the seeds when the soil dries out. If you are in an area that receives an adequate amount of rainfall, you may not have to water your seeds. Keep the soil moist.
Sow the seeds in the garden 18 months after you have placed the seeds in the pots. Loosen the soil in your seed bed with a hoe, and push the seeds approximately 1/4 inch into the soil. Cover the soil lightly.
Water the seeds with 2 inches of water every week. Thin out the seedlings once they begin to grow. Leave the tallest ones to grow.
Apply 2 inches of mulch at the base of the tree as it begins to grow. This will hold in moisture and keep weeds at bay.
