Press 2 to 3 raspberry seeds about 1/4 of an inch into the soil of each cell. The same as planting any other seeds in starter trays, gently compact the soil to remove excess air.
Lightly dampen the soil and keep it moist, but not saturated for the entire germination process. Too much water can lead to fungus and decay and destroy your raspberries before they even sprout. Place the planted seeds in a cool, dark area above 35 °F till germination, which should take about 3 months.
Planting your seeds in Early Autumn will give sprouts in early January - not a good time to plant them outside. Place the seedlings in a warm sunlit and keep them well watered, once again not saturated just well watered. If you have the facilities to do so grow lights would be swell - bit not absolutely essential.
