How to Germinate a Plum Seed
- 1). Remove the seed from the plum and scrub it under warm running water to wash away the flesh of the fruit. Any leftover flesh may potentially lead to rot.
- 2). Plant the seed between 2 and 4 inches deep in a sunny location. Cover the seed with soil and tamp it down lightly. It's best to plant in late fall, just before the ground freezes.
- 3). Leave the seed in the ground throughout the winter months. The seed should crack open during this stratification period, which in turn makes it more likely to germinate.
- 4). Keep the soil moist, but not soggy once spring comes around. As long as the seed gets moisture and exposure to sun, it should germinate by the middle of summer.
