Free and Low-Cost Ways to Get Plants, Seeds, and Cuttings

Seed libraries operate out of public libraries, community centers, and cooperative extension offices across the US. You borrow seeds, grow your plants, and — ideally — return seeds at season's end to keep the library stocked. Many don't require you to return anything, making them genuinely free. Search your county library's website or call your local cooperative extension office to find one nearby. Selections often lean toward open-pollinated and heirloom varieties, which are well-suited to seed-saving for future seasons.

Community plant swaps happen in church parking lots, farmers' markets, community gardens, and neighborhood parks — often in spring and fall. Participants bring divisions, cuttings, or packed seed envelopes and trade with other growers. If there's no swap near you, organizing one through a local Facebook group or Nextdoor takes minimal effort and tends to attract enthusiastic participants quickly. Even a small swap among a half-dozen neighbors can yield a meaningful haul of diverse plant material.

Many common houseplants and garden plants — pothos, coleus, basil, rosemary, mint, hydrangeas — root easily from stem cuttings placed in water or moist soil. This is arguably the most scalable free strategy because one plant can produce dozens of new starts over a season. The basic process: take a 4–6 inch cutting just below a leaf node, remove lower leaves, and place in water or a well-draining propagation mix. Results vary by species, but most herbaceous plants and soft-wooded shrubs respond well. Check species-specific guidance before attempting woody or succulents, as methods differ.

Platforms like Nextdoor, local Facebook gardening groups, and Freecycle regularly feature posts from gardeners offloading divisions, surplus seedlings, or potted plants they no longer have space for. These giveaways are often hyperlocal — someone a few blocks away thinning out their hostas or clearing a raised bed. Set up keyword alerts for terms like "free plants," "seedlings," or "garden giveaway" in your area. Response times matter: popular posts move quickly, so act the same day if you see something useful.

Open-pollinated and heirloom varieties — as opposed to hybrids — produce seeds that reliably reproduce the parent plant. Tomatoes, peppers, beans, peas, and squash are among the easiest to save from. Allow a few fruits to fully ripen beyond eating stage, extract and dry the seeds, then store them in a cool, dry place in labeled paper envelopes. Done consistently, seed saving creates a self-sustaining supply. Note that hybrid varieties (often labeled F1) won't breed true, so check what you're growing before saving.

Nurseries discount unsold stock heavily as the season winds down — perennials, shrubs, and trees can drop to 50–75% off their peak price. These plants aren't dead; they're just dormant or past their showiest phase. Perennials in particular are worth buying late because they'll establish over winter and come back strong the following spring. The trade-off is limited selection and some variability in plant condition, so inspect root systems before buying and avoid anything with signs of disease or severe root binding.

Many perennials — hostas, daylilies, ornamental grasses, coneflowers — need to be divided every few years to stay healthy. Gardeners with overcrowded clumps are often grateful for someone to help dig and take divisions. Ask neighbors with established gardens whether anything needs thinning, or post in a local gardening group. Division is best done in early spring or fall when temperatures are mild. Divisions transplant well and typically establish faster than seedlings, giving you a head start on a mature-looking planting.
