Growing pear trees from seed can be fun and educational. There are more than 20 species of pear trees within the botanical genus pyrus. Although fruit trees grown from seed usually don't turn out exactly like the original, you can still get a plant that will bear fruit. However pear trees do require cross-pollination which means you will need another tree within 500 feet for fruit to be produced. If there are no other pear trees in the vicinity you must plant two seedlings.
Cut open a pear being careful not to damage the seeds. Remove the seeds and rinse with cool water. Fill the bottom of a plastic bag with some peat moss mix place the seeds on top. Cover the seeds with some more peat moss and add a little water to moisten the soil.
Seal the bag and place it in the refrigerator for 60 to 90 days to allow the seeds to stratify. Stratification is the process by which the seeds break their dormancy. In nature it occurs when the fruit falls from the tree and the seeds lay on the cold, damp ground over the winter. The ideal temperature for stratifying pear seeds is 32 to 45 degrees.
Prepare your potting mix by blending equal parts of potting soil, sand and peat moss. Fill your planting containers. The pots need to have drainage holes in the bottom. Remove the seeds from the bag and plant them about 1/2 inch below the surface of the soil. Add a little water and set the pots on a tray in a warm, sunny location such as a window.
Keep the soil moist and let the seedlings develop several sets of leaves before transplanting to the garden. Seedlings should be planted in the spring when the risk of frost has passed. Pear trees need plenty of sunshine and prefer rich, well drained soil that is slightly acidic.
