Strawberries are one of the most delicious, nutritious and popular summer fruits around. Germinating strawberry seeds is a relatively straightforward process and when carried out under optimal conditions can produce strawberry plants of excellent quality. The key factor for successful germination is the cooling of the seeds before planting. Use a household freezer and airtight plastic containers to chill your seeds.
Buy strawberry seeds from a reputable seed retailer or extract seeds from your favourite strawberry plants. Allow the strawberries to dry out and then rub the seeds off while holding over a clean bowl or piece of wax paper. You can also press the fresh ripe berries through a fine metal kitchen sieve and then wash the seeds that remain in the sieve bowl. Be sure the seeds are completely dry before placing them into the plastic container for their time in the freezer.
Freeze the dry strawberry seeds by keeping the airtight plastic container in the freezer for at least four weeks and up to four months. Remove the seeds from their cold storage and plant immediately.
Prepare a seedling tray or pots with at least 5 cm (2 inches) of rich. well drained and moist soil with a bit of peat moss mixed in. Plan to sow six to 10 seeds per pot.
Bury the seeds under a covering layer of peat moss approximately 3 mm (1/8 inch) thick. Mist over the peat moss cover with water to set. Leave in an indirectly lit location to sprout.
Transplant developed seedlings with at least four to six leaves to larger pots or to outdoor containers or beds, keeping the soil level consistent on the main stem and keeping the seedlings well watered.
