Sow indoors in flats with good potting soil as early as February, but no later than April. Keep warm and well-watered. Transplant seedlings into 4” pots when they have their first two true leaves. Transplant into the garden after danger of frost has past, typically late May in western Oregon.
Collect seeds from ripe fruit. Place in a small jar and add 50% more water. Wait for mold to form. When seeds sink and gel-sac is gone, decant to clean and dry on windowsill.
