Starting a resilient food garden
Balance fast nutrition with staple calories, soil protection and seed saving.
Critical caution: Local climate, soil contamination, water availability and poisonous look-alikes must be assessed.
- Time
- Seasonal
- Difficulty
- Moderate
- Outcome
- Produce food while improving soil and preserving seed
Survival lens: Gehring’s practical self-sufficiency is applied as a system rather than a hobby garden: calories, soil, water, storage and seed must all work together.
Before you begin
- Test or investigate soil contamination
- Map sun, drainage and frost
- Secure a realistic water supply
What you need
- Spade, fork and hoe
- Watering equipment
- Mulch and compost
- Locally suitable seed
- Labels and notebook
Step-by-step procedure
- Map the site. Record daily sun, wet areas, wind, frost pockets, existing perennials and safe water access.
- Protect soil first. Keep soil covered with mulch or crops, minimise compaction and direct runoff along contours rather than down bare slopes.
- Plant two horizons. Combine fast greens and herbs with locally suitable calorie or protein crops. Avoid betting the season on one variety.
- Use water precisely. Water roots deeply at cooler times. Repair leaks, group plants by need and record consumption.
- Observe weekly. Record emergence, pests, disease, weather and harvest weight. Intervene early with the least hazardous method.
- Save seed selectively. Save from healthy, correctly identified open-pollinated plants. Dry, label and store cool, dark and dry.
How to check it is working
- Water demand fits supply
- Food beds are isolated from waste and chemical contamination
- At least two crop types reduce failure risk
- Seed records include variety and year
Common mistakes
- Planting only salad crops with few calories
- Expanding beyond watering capacity
- Using unknown compost on ready-to-eat crops
- Saving seed from diseased or hybrid plants without understanding outcomes
