Sow, grow, and harvest for self-sufficiency, tailored for the UK's changing seasons.
Growing your own food is the most fundamental step towards self-sufficiency. This guide provides an essential, month-by-month calendar covering key planting, maintenance, and harvesting tasks for both outdoor vegetable plots and small greenhouses. It is tailored for the typical growing conditions of the North West UK.
Spring: Sowing, Planting, and Preparation (March - May)
This is the busiest time for starting seeds indoors and preparing your beds outdoors. Focus on cold-tolerant crops and getting your warm-weather plants (like tomatoes) established in the greenhouse.
| Task Category | Greenhouse / Indoors | Outdoor Plot / Polytunnel |
|---|---|---|
| Sowing | Start Tomatoes, Peppers, Cucumbers. Start early batches of Lettuce and Cabbages in trays. | Sow Carrots, Parsnips, Radishes, Broad Beans, Peas, Spinach, Swiss Chard. |
| Planting | Harden off and move out hardy seedlings. Plant First Early Potatoes in pots. | Plant Onion Sets, Shallots, Second Early Potatoes. Transplant hardy greens like Kale and Spring Cabbage. |
| Maintenance | Clean glass/plastic to maximize light. Start watering young plants regularly. Begin weeding outdoor beds. | Apply Compost or Well-Rotted Manure to empty beds. Erect supports for peas and beans. Hoe weeds regularly. |
Summer: Growth, Watering, and Pest Control (June - August)
Summer is all about managing growth, ensuring adequate water supply, and staying on top of pests and diseases, especially in the humid greenhouse environment.
| Task Category | Greenhouse / Indoors | Outdoor Plot / Polytunnel |
|---|---|---|
| Sowing | Sow successional batches of Lettuce, Endive, Basil (for continuous harvest). | Sow successional crops of Carrots, Beetroot, French Beans, Runner Beans. Sow Winter Cabbage for late harvest. |
| Planting | Plant main Tomato, Cucumber, and Pepper plants into final positions. | Transplant Leeks, Brussels Sprouts, Winter Greens. Plant Maincrop Potatoes. |
| Maintenance | Ventilate heavily. Water frequently and feed tomatoes/cucumbers with high-potash feed. Pinch out tomato side shoots. | Water regularly, especially in dry spells. Mulch beds to retain moisture. Pinch out tips of broad beans to deter blackfly. |
| Harvest | Early Tomatoes, Cucumbers, Strawberries. | New Potatoes, Peas, Beans, Summer Cabbage, Courgettes, Raspberries, Soft Fruit. |
Autumn: Main Harvest and Winter Preparation (September - November)
Autumn brings the main harvest of root crops and fruits, while your focus shifts to clearing space and planting hardy crops for spring and winter supply.
| Task Category | Greenhouse / Indoors | Outdoor Plot / Polytunnel |
|---|---|---|
| Sowing | Sow quick winter crops like Winter Lettuce and Spinach in the greenhouse. | Sow Winter Field Beans (green manure). Sow hardy varieties of Broad Beans and Peas. |
| Planting | Plant Garlic and Shallots. Plant Perennial Herbs and Soft Fruit into cleared ground. | |
| Maintenance | Remove spent summer crops. Reduce ventilation gradually and clean glass to maximize light. | Clear spent crops. Work in organic matter/manure to improve soil structure for next season. |
| Harvest | Final harvests of Tomatoes, Peppers, and Aubergines. | Maincrop Potatoes, Pumpkins, Squashes, Brussels Sprouts, Celeriac, Leeks, Swede. |
Winter: Planning, Rest, and Protection (December - February)
While the land sleeps, this is the time for planning, ordering seeds, and essential plot maintenance to ensure a successful start to the next growing year.
| Task Category | Greenhouse / Indoors | Outdoor Plot / Polytunnel |
|---|---|---|
| Sowing | Sow early, slow-growing seeds like Broad Beans and Cabbages in a heated propagator or warm windowsill. | Sow no major crops. Focus on protecting existing hardy winter crops. |
| Planting | None (unless forcing rhubarb/chicory in the dark). | If weather is mild, continue planting Garlic and Onion Sets for an early start. |
| Maintenance | Check greenhouse structure for repairs and clean tools. Order new seeds. | Winter Digging (if soil is not waterlogged). Cover bare soil with Mulch or Black Plastic to suppress weeds and warm the soil. |
| Harvest | Winter salads like Lamb's Lettuce and hardy Spinach. | Leeks, Parsnips, Celeriac, Brussels Sprouts, Jerusalem Artichokes. |
