A longer growing season means more food from the same ground, and most of the gain comes from knowing your frost dates and using a few simple protections.
Know your own season first
The book says a kitchen garden teaches you the soil, the microclimate, the frost dates and the local pest pressures. Learn the average dates of the last spring frost and the first autumn frost for your site, using national weather service or local agricultural advice, because every technique below is about working at the edges of those dates.
What the book suggests
- Use raised beds. They warm up faster in spring and drain better, which lets you plant a little earlier.
- Protect seedlings with cover fabric. The book says covers shield young plants from insects and light frosts.
- Shelter the garden from wind with a fence, which also helps warmth stay put.
- Match crops to the calendar. Winter squash and pumpkins go in during late spring and are harvested in autumn, while leafy greens can be cut repeatedly through the season.
- Plant perennials early. Fruit trees, berry bushes and perennial vegetables crop year after year without replanting.
Other techniques to research
The books concentrate on the basics above. Gardeners elsewhere also use cold frames, low tunnels and greenhouses, and sow successive batches of quick crops. These are common, but how well they work depends on your climate and how much work you can sustain, so read local guidance before investing.
Plan storage for the end of the season
Extending the season is only half the job. Crops that store well, such as roots, potatoes and winter squash, carry the harvest through winter (choosing crops), and preserving the surplus is covered in planning an off-grid food supply.
Keep it manageable
- Record your frost dates and planting dates each year.
- Try one new protection at a time.
- Keep the garden small enough to manage in a rush, such as before an unexpected frost (planning a survival garden).
More on timing and protection is in the Survival Garden guide. If you want a broader plan for feeding yourself all year, see Off Grid Survival for Beginners.
