Common Seed Project Resource Guide: 2025 Common Seed - The Common Seed Project - LibGuides at University of Massachusetts Amherst

Inspired by "common read" programs that bring people together through shared reading experiences, Common Seed builds community through gardening and seed saving. Each year, we select a “common seed,” and participants across western Massachusetts receive free seeds from participating libraries, along with access to local events, workshops, and resources.

This year’s seed is the ‘Provider’ Bean—perfect for gardeners of all levels!

When to plant: Seeds can be planted as early as 1-2 weeks before the last spring frost date, typically the 3nd or 4th week of May in the Pioneer Valley, up to midsummer.

Where to plant: Choose a sunny spot with well-draining soil. Plant your seeds directly in the ground, a raised garden bed, or a container.

How to plant: Seed depth: 1"
                        Seed spacing: 3-4"
                        Row spacing: 18-24"

Care: Give your seeds a deep watering after planting. Keep the soil consistently moist but not waterlogged until germination, which should take 6-12 days. After the first week, reduce watering to once every 3 days. Once the plants are established water as needed—typically about twice a week, depending on weather conditions.

Harvest: ‘Provider’ beans are ready to harvest when they reach 5-6 inches in length, about 50 days after planting. Gently tug or cut to remove beans to avoid plant damage. Harvest regularly to encourage continuous production. Avoid picking beans when the plant is wet to reduce the risk of disease.
