Milkwood: Build a Seed Bank – Save Tomato & Cucumber Seeds

Key Takeaways

Build a personal seed bank by mastering wet and dry seed extraction, fermentation, drying, and storage with permaculture principles.

• Learn wet and dry seed extraction techniques.
• Ferment tomato seeds to boost viability.
• Properly dry seeds to prevent mold and spoilage.
• Label and store seeds for long-term use.
• Adapt seed saving to your local climate.

Why It Matters

Saving your own seeds increases food sovereignty, adapts crops to your local environment, and reduces waste by utilizing discarded produce.

What to Do Next

Start saving seeds from a ripe tomato or cucumber using the wet or dry method described.

Permaculture Context

Seed saving sits at the heart of genuine food sovereignty, and for permaculture practitioners it represents something far more strategic than a frugal garden habit — it's the foundational act of closing biological loops within your system. Every season you save seed from your strongest, best-adapted plants, you're essentially running a low-cost, site-specific breeding programme that no commercial catalogue can replicate for your microclimate, your soil, your conditions. This matters enormously right now, as supply chain fragility and increasing seed industry consolidation continue to narrow the genetic diversity available to home growers. Mastering fermentation technique, in particular, shifts seed saving from passive collection into active viability management — a meaningful distinction when you're depending on germination rates in a serious food garden. The deeper implication is systemic: a functioning personal seed bank transforms your growing practice from one of annual dependency on external inputs into a genuinely regenerative, self-reinforcing cycle. That's not a marginal improvement in resilience — it's a structural one, and it compounds meaningfully over years of careful selection and storage.
