Start indoors or direct sow?

Start seeds indoors because they are tiny, slow to germinate, and need a long head start. Transplant after frost risk has passed, although established strawberry plants tolerate cool weather better than young seedlings.

When to start Strawberries seeds

Start seeds indoors about 10 to 16 weeks before the average last spring frost. Many gardeners sow even earlier in winter after cold stratification, so plants are large enough to set out in spring.

How to sow the seeds

Cold stratify seed in a sealed container in the refrigerator for about 3 to 4 weeks if the packet does not state it was pretreated. Surface sow on moist sterile seed-starting mix in shallow cells or trays, press lightly without covering, and provide bright light for germination.

Germination

Germination often takes 14 to 30 days, sometimes longer depending on variety and pretreatment. Keep the surface consistently moist with a cover or bottom watering, at about 60 to 75 F, then ventilate promptly after sprouting.

Seedling care

Give seedlings strong light for 12 to 16 hours daily and water gently so the tiny plants are not displaced. Provide airflow after emergence, avoid overwatering, and thin or transplant seedlings into individual cells once they have several true leaves.

Transplanting & hardening off

Harden seedlings off for 7 to 10 days and plant after the last frost into full sun and well-drained soil. Set crowns at soil level, with roots spread downward, because buried crowns can rot and exposed crowns can dry out.

Tips

Use a spray bottle or bottom watering during germination so seed does not wash away. Be patient, since strawberry seedlings grow slowly at first.
