20 Raspberry Seeds

Raspberries (Rubus idaeus) require a climate offering moist, somewhat cool conditions. Gardeners can successfully grow plants at home using fresh seeds. Fill a 2-inch-deep nursery tray with sterile, low-nutrient seed-starting compost. Spray the compost liberally with a water-filled spray bottle until it feels moist throughout. Space the raspberry seeds 1 inch apart on the surface of the seed-starting compost. Press the seeds firmly onto the surface of the compost with your palm. Cover them with a very thin layer of medium-grit sand. Place the nursery tray outdoors in a ventilated cold frame that stands against a shaded, north-facing wall. Leave the tray under those conditions for the winter months to cold stratify, which will break the seeds' dormancy. Maintain light moisture in the seed-starting compost with the water-filled spray bottle. Avoid letting the compost dry out for longer than a few hours since very dry conditions sometimes cause raspberry seeds to go dormant again. Rem
