Getting many varieties of peach seeds to grow is relatively easy, but keep in mind that some varieties are difficult to start and some varieties, such as Red Haven and other early-season peaches, are almost impossible for the home gardener to start from seed. It is a good idea to gather seeds from several varieties of peach and start them at the same time to ensure that at least one or two will take. Follow some steps to learn the cold-treatment method of starting peach seeds.
Remove the pits from several peaches just after the fall harvest and wash them thoroughly, removing all of the peach flesh from the seeds. Pat the seeds dry with paper towels and allow them to dry overnight.
Place the seeds into plastic baggies with the tops just slightly open and store the seeds in the refrigerator until December. Do not store apples in the same refrigerator as one of the gasses that apples release as they are stored will harm your peach seeds.
Remove the seeds from the refrigerator in December or January and soak them in room temperature water for three to four hours.
Put the seeds into vermiculite or perlite in a plastic baggie. The vermiculite or perlite should be slightly moistened. Seal the baggie and place it in the refrigerator for four to six weeks, until a root begins to grow from the seed.
Transplant the rooted seed to a growing pot which contains a 50/50 mix of garden soil and vermiculite or perlite. Plant the seed approximately 2 inches deep with the root pointing down. Keep the soil moist but not soggy and keep the pot indoors in a bright location but out of direct sunlight.
Dig a hole that is five or six times the size of your seed in a sunny garden location and mix approximately 1/3 vermiculite or perlite with your garden soil. Plant your seeds just below ground level once all possibility of frost has passed in early spring. Keep ground moist but not too wet.
