Summer Squash Seeds,
Odessa

Sow Odessa squash after the last frost when soil temperatures are at least 70°F. In cooler zones, start seeds indoors 2–4 weeks early and transplant after danger of frost. Don’t let transplants get rootbound and don’t disturb the roots when transplanting. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Note that there are four different species of squash: Cucurbita maxima, C. pepo, C. moschata, and C. mixta. They will not cross pollinate with each other, so it is possible to grow one of each species for seed saving without worrying about cross pollination. If you are planning to save seeds from several varieties of the same species, you can bag the blossoms and hand pollinate to avoid crossing.

• Allow fruit to fully mature on the vine until the skin hardens and color deepens.
• Harvest mature squash and cure for two weeks in a warm, dry area.
• Cut open and remove seeds.
• Rinse seeds to remove pulp and dry on a screen or paper towel in a well-ventilated area for 2–3 weeks.
• Store in a cool, dry place in a labeled envelope or airtight container.
