Growing a pear tree from a seed is relatively easy--but be aware that any tree grown from a seed will not necessarily produce the same great tasting fruit as the parent tree. This is because in order for a pear seed to be viable, it must contain a mix of genetic material, and this mix may not produce a tree with the same flavor as the fruit that the seed came from. In order to produce a pear tree with the exact same flavor characteristics as the pear you are trying to imitate, you would need to graft wood from the good tree onto pear rootstock; in this way you could create a "clone" of the original tree with the delicious fruit. However, if you wish to grow a pear from a seed, there is little standing in your way.
Collect your pear seeds, wash them under running water and pat them dry with a paper towel.
Fill one or more 4-inch planting pots with potting soil. Plant one pear seed in each pot, approximately 1/2 inch deep. Dampen the soil.
Insert the pot into a large baggie and zip the baggie shut. Place the bagged pot into the refrigerator and leave it until all possibility of frost has passed for your area.
Remove the baggie and pot from the refrigerator and remove the pot. Place the pot in a warm place with plenty of indirect sunlight and mist the soil daily. Keep it damp but do not saturate it.
Plant your young seedlings outdoors in a sunny location with well-drained soil. Dig a hole at least twice the size of your tree's root ball and mix compost into the soil in a 50/50 mix. Keep the soil damp, but do not allow the ground to become saturated. Protect your young tree from deer, rabbits and other hungry wildlife with wire mesh.
