Chandler’s Fall Seed Swap Puts Free Seeds, Starts, and Cuttings in East Valley Hands

The cheapest way to start a fall garden in the East Valley may be a paper envelope and a conversation with a neighbor. This Sunday, Chandler is setting out the envelopes.

The city’s free Fall Seed Swap runs Sunday, October 11, from 1:30 to 3:30 p.m. at Sunset Library, 4930 W. Ray Road. Gardeners are invited to bring and trade seeds, seed starts, and plant cuttings, and to meet local gardeners, Master Gardeners, and other residents who can help them start or maintain a desert garden. Envelopes and markers will be provided, and a limited supply of bags will be on hand. Nobody has to bring anything to take part. The city pitches it as a good first step for people new to Arizona who want to establish a garden of their own.

There will also be something a little more local than a store-bought packet on the tables: seeds harvested from the Native Plant Oasis at Veterans Oasis Park.

Why fall is swap season in the low desert

Many seed swaps elsewhere are timed to spring planting. In the low desert, the calendar runs differently. Summer heat slows most vegetable gardens to a crawl, and fall is when beds fill back up. The city’s own announcement for the event opens with a simple line: “Fall planting season has arrived!”

That timing makes a swap more useful than it might sound. A new gardener who picks up a few packets this weekend can have them in the ground within days, while the weather is still warm enough for fast germination and cool enough that seedlings are not fighting triple-digit afternoons. Seed starts and cuttings shared by experienced growers also come with something a packet cannot offer, which is the word of someone who has already grown that plant in this soil and this sun.

A seed library that never closes for the season

The swap is hosted at the branch that anchors Chandler Public Library’s year-round Seed Library. Library cardholders can choose up to three seed packets per household each month for free by bringing their seeds and library card to the front desk. Seeds cannot be placed on hold, and what is available depends on supply and season. There is no obligation to bring anything back.

The Seed Library is stocked at all four Chandler library locations and aboard the Chandler Discovery Library, with the largest selection at Sunset. Donated seeds are accepted only at Sunset, where envelopes are available, and the library asks donors to include as much information about their seeds as possible.

For residents who cannot make it to a branch, the Discovery Library is bringing seeds on the road this month. Scheduled stops include Cadence Chandler on Saturday, October 10, from 1 to 3 p.m.; Tumbleweed Recreation Center on Tuesday, October 13, from 10 a.m. to noon; and Sunrise Apartments that same day from 2 to 4 p.m.

Chandler is not alone. Mesa Public Library lets cardholders check out three free seed packets a month for edible plants and herbs, with varieties rotated by season and chosen for local growing conditions. Its seed collections are at the Main, Red Mountain, Dobson Ranch, Mesa Express, and Gateway libraries and on the Read Runner bookmobile, and gardeners are encouraged to save seeds and donate them back. Maricopa County keeps a running list of seed libraries that includes Tempe, Scottsdale, the Maricopa County Library District, and the Maricopa Native Seed Library, which offers free native seed. The University of Arizona’s Maricopa County Master Gardeners also maintain a map of seed libraries, school gardens, and community gardens across the county.

How to save seed worth sharing

A swap works best when the seed on the table grows into what the label promises. Native Seeds/SEARCH, a seed conservation organization focused on Southwestern crops, publishes seed-saving instructions that are a good fit for desert gardeners. A few of its basics are worth knowing before the next swap.

Start with the easy crops. Native Seeds/SEARCH points to the International Seed Saving Institute’s list of beginner crops: bean, lettuce, pea, pepper, and tomato. Beans are especially forgiving. The organization explains that bean flowers pollinate themselves before they even open, so a bean variety is unlikely to cross with the one next to it.

Know what crosses with what. Squash, melons, and gourds carry separate male and female flowers and depend on insects to move pollen, and varieties within the same species cross readily. Zucchini, acorn, crookneck, spaghetti squash, and Halloween pumpkins all belong to one species, Cucurbita pepo, so seed saved from a zucchini grown near a pumpkin may not come true. The simplest fix, according to Native Seeds/SEARCH, is to grow only one variety of any one species at a time. The group also notes that the standard one-quarter-mile isolation rule may be more than the Southwest needs, since dry heat quickly desiccates pollen.

Skip hybrids. Seeds saved from hybrid varieties often do not reproduce the traits of their parents. Open-pollinated and heirloom varieties are the ones to save and share.

Harvest at the right moment. Beans, peas, chiles, okra, and other “dry” fruits are ready when the seeds rattle in their pods or begin to fall. “Wet” fruits such as tomatoes, melons, and squash should be picked slightly overripe but not rotten. Tomato seeds need an extra step: Native Seeds/SEARCH describes blending ripe fruit, letting the pulp ferment for three to five days, then rinsing off the floating debris until only the clean seeds that sink remain.

Dry and store with care. Seeds should dry on cotton towels or screens, never newspaper or paper towels, out of direct sun, and never in an oven. In a climate as dry as ours, the group says seeds can usually equilibrate in an air-conditioned room for about a week before being sealed in airtight jars or bags. Store them cool, dark, and dry, not in an outdoor shed. Freezing seeds for three days kills insects such as the bean weevils that leave small holes in stored beans, and frozen seed of many crops can last 10 years or more.

Finally, save only from healthy plants. Some plant viruses travel in seed, so seed from diseased plants should stay out of the envelope.

Making the most of Sunday

A few small habits make a swap better for everyone. Label every envelope with the plant, the variety, and the year it was saved, along with anything a new grower would want to know, such as whether it is an heirloom or how it handled the heat. Bring seeds in small amounts so more people can take some home. If you are bringing seedlings or cuttings, a note about sun and water needs goes a long way for someone who just moved here from a wetter state.

New gardeners should come with questions as much as seeds. The event is built around face-to-face advice from Master Gardeners and experienced locals, and that knowledge is the part of a seed swap that never runs out.

The Fall Seed Swap is free and open to the public. For details, call Chandler Public Library at 480-782-2800. The Seed Library at Sunset stays open after the tables are cleared, so a packet picked up this weekend can come back next fall as a handful of seeds for the next gardener.
