Pears are one fruit that many people wonder about planting when they are children. Some people try to do this as adults, but often miss the first few steps needed to ensure success. If you follow the steps properly, you will usually have viable pear trees growing in your own garden. Pear trees will not bear fruit for roughly 4 years when grown from seed.
Slice the pear in half lengthwise. Pick out the seeds and enjoy the pear as a snack. Make sure the pear is ripe enough so you can pull the seeds out without clinging to the pear.
Put water in the small bowl about halfway. Place the pear seeds into the water and allow the seeds to sit overnight. Use a strainer to pour the water into, catching the seeds in the strainer. Put the pear seeds on a paper towel. Fold the towel over them and pat dry.
Fill the plastic cups half full of potting soil. Poke a finger-sized hole in the center of the soil for each cup. Put a seed into each hole and cover with soil. Dampen down the soil with a little water to make the soil moist.
Place the cups with the seeds on a shelf in the refrigerator. Put the cups on the side of the shelf, but not in the back corners. Seeds require a temperature range from 35 to 40 degrees Fahrenheit to root; the back corner of the refrigerator is too cold and will freeze the pear seeds. Refrigerate the seeds for up to 3 months, checking for root growth every 30 days. White roots will be showing against the side of the cup when the seed has begun to root.
Keep the rooted pear seeds in the cups and move the cups to a window where they can get sunlight. The new root system will need a temperature of 70 degrees Fahrenheit to maintain growth. Water the plants to keep the soil damp. When you see sprouts coming up from the soil, it will be time to transplant the seedlings.
Using the knife, cut the milk cartons in half widthwise. Fill the cartons with potting soil and dig a small hole in the center. Scoop the seedlings from the cups and transplant them into the milk cartons. Cover the roots with soil and water lightly.
Allow your new trees to grow about 3 inches before moving them outdoors. Start this project in December and the seedlings will be ready for their home by the last frost ahead of spring. Keep your trees in the window until you are ready to move them.
Find the permanent location for your new pear trees. Stay away from low ground where water collects because the trees will drown. Dig the holes, roughly 1 inch in diameter larger than the milk cartons. Place the milk cartons in the holes but don't bury them, just make sure they fit. Remove the milk cartons and cut away the cartons from the trees. Plant the trees in their new home and cover the roots with soil. Water slightly to help them get started.
