How to Germinate Organic Raspberry Seeds

Select the type of raspberries you want to grow. There are many different species of raspberries, all of which can be started from seed. Make sure you start with an organic seed, however, which you can purchase at a nursery or seed store, and select a type of raspberry that will thrive in your location. You can also start seeds leftover from previous organic raspberry crops.

Start your seeds in the early autumn, approximately six months before you will plant the seeds outside.

Fill flats three-quarters full with a starter soil mix that contains perlite, vermiculite, or peat moss. Make sure the starter mix you use is organic. If you have your own homemade compost, you can use that instead of a store-bought mix.

Plant the seeds 1/2 inch into the soil and space the seeds approximately 1/4 to 1/2 inch apart in the rows. Rows should be approximately 2 inches from each other.

Water the flats until the soil is moist but not flooded. Throughout the six months, you will want to make sure the soil does not get dry to the touch, but avoid over watering the seeds.

Keep the seeds in a room with a sustained temperature between 68 to 86 degrees F for the first 90 days. After 90 days, the seeds will need cold stratification, which means you need to keep the seeds in a room exposed to 36 to 41 degrees F for another 90 days.

Plant the seedlings outside once there is no longer any chance of frost.
