Simple Agriculture: How to Plant, Grow and Harvest Your Own Food

For millennia, every human family knew how to grow food. It was as fundamental a skill as cooking — as obvious as breathing. In just a few generations, that connection has been almost entirely lost. Most people today don't know where their food comes from, how it grows, or how to produce it if needed. The good news is that growing food is surprisingly simple. You don't need perfect fertile soil, expensive equipment or decades of experience. With basic knowledge, any space — a backyard, a balcony, a rooftop — can produce real, nutritious and abundant food.

🌿 PART 1 — Soil Preparation

🧱 Soil Types and How to Improve Them

Clay soil (heavy, sticks to hands): retains too much water — root rot risk. Improvement: coarse sand + compost in 1:1:1 ratio.

Sandy soil (dry, doesn't hold shape): drains too quickly. Improvement: generous compost + clay.

Ideal soil — Loam: balanced, dark, loose, earthy smell, visible earthworms. Add only annual compost.

🪱 How to Make Compost (The Foundation of Everything)

Compost is the "brown gold" of farming — transforms waste into high-quality fertiliser and feeds the microorganisms that make nutrients available to plants.

Greens (nitrogen): fruit and vegetable scraps, coffee grounds, eggshells, fresh grass clippings, green leaves

Browns (carbon): dry cardboard, newspaper, dry leaves, straw, untreated sawdust

Never add: meat, fish, dairy (attracts pests), diseased plants, carnivore droppings

Ideal ratio: 3 parts browns to 1 part greens

Process:

  1. Start with a 10 cm layer of dry brown material

  2. Add a 5 cm layer of green material

  3. Moisten lightly (should feel like a gently squeezed sponge — damp but not wet)

  4. Turn/mix every 1 to 2 weeks to oxygenate

  5. In 60 to 90 days: compost ready — dark, moist, smelling of fresh earth

💧 Physical Soil Preparation

Raised bed (the most efficient for beginners): Ideal dimensions: 1.2 m wide × any length × 30 cm high. The 1.2 m width lets you reach the centre without stepping on the bed — critical for preventing compaction.

Layer filling:

  1. Bottom: broken thick branches (drainage + slow decomposition = nutrients)

  2. Middle: moistened cardboard layer (suppresses weeds)

  3. Mix: 60% local soil + 30% compost + 10% coarse sand

  4. Top: mulching (straw, wood chips) to retain moisture and suppress weeds

🌾 PART 2 — What to Plant: The 10 Best for Beginners

🥬 1. Lettuce (30–50 days): easiest of all. Tolerates partial shade. Leaf-by-leaf harvest — lasts months.

🫑 2. Rocket/Arugula (20–40 days): extremely fast. Germinates in 5–7 days. Rich in iron and vitamin C.

🥕 3. Radish (25–35 days): one of the fastest vegetables. Perfect for teaching children.

🧅 4. Spring Onion and Parsley (30–60 days): high-yield aromatics in small space. Virtually foolproof.

🥒 5. Courgette/Zucchini (50–70 days): extraordinary productivity — one healthy plant can produce 10–15 kg per season.

🍅 6. Cherry Tomato (60–80 days): simpler and more tolerant than regular tomato. High yield in pots or beds.

🫘 7. Green Bean (50–60 days): one of the easiest protein sources to grow. Fixes nitrogen in the soil.

🥦 8. Kale (60–90 days): extremely nutritious. Cold-resistant. Leaf-by-leaf harvest for months.

🌿 9. Basil (30–50 days): repels unwanted insects. Great planted next to tomatoes. Easy in pots.

🧄 10. Garlic (120–180 days): long wait but high value — antibacterial, universal seasoning, long shelf life. Plant in autumn for summer harvest.

🌱 PART 3 — How to Plant

🌰 Direct Seeding vs Transplanting

Direct seeding: carrot, beetroot, radish, bean, pea — plants that don't tolerate transplanting well. Make shallow furrows, plant 2–3 seeds per spot, thin to the strongest seedling.

Seed trays (for transplanting): tomato, pepper, broccoli, kale, lettuce. Transplant when seedlings have 4 to 6 leaves — soak the container in water first to ease removal.

💧 Correct Watering

The finger rule: insert your index finger to the second knuckle into the soil. If damp — don't water. If dry — water.

When to water: preferably early morning or late afternoon. Never at midday. Never wet the leaves of tomatoes or courgettes — promotes fungal disease.

🌿 PART 4 — Care and Maintenance

🐛 Pest Control Without Pesticides

Garlic and chilli spray: blend 5 garlic cloves + 2 chillies + 1 litre of water. Strain and dilute 1:10. Spray weekly as a preventive.

Diluted coconut soap: 2 tablespoons in 1 litre of water. Effective against aphids, mites and whitefly.

Companion plants that repel pests:

  • Basil next to tomatoes — repels whitefly

  • Marigolds around the bed — repels nematodes and insects

  • Garlic next to roses and vegetables — repels aphids and fungi

  • Mint at borders — repels ants and aphids (caution: invasive, plant in pots)

Physical controls:

  • Hand-picking caterpillars and slugs (early morning or at night)

  • Beer trap for slugs: pot buried at soil level filled with beer

  • Thick mulching: disrupts the life cycle of many pest insects

🌾 Maintenance Fertilisation

  • Compost: apply 2–3 cm on the surface every 4–6 weeks

  • Liquid compost (worm tea): dilute 1:10, apply at plant base every 2 weeks

  • Wood ash: rich in potassium and calcium, sprinkle around plants every 4 weeks

🎉 PART 5 — Harvest: How and When

⏰ How to Know the Right Time to Harvest

Tomato: harvest when 70–80% of the surface is red and the flesh yields gently to the touch.

Courgette/Zucchini: harvest at 15–20 cm — younger is more flavourful and the plant keeps producing.

Lettuce: harvest outer leaves at 10–15 cm. Harvest whole plant when it starts to bolt (flower).

Carrot: pull when the top of the root is visible at 1 cm diameter.

Green bean: harvest when pods are firm and full but before the beans inside visibly bulge.

Kale: harvest leaves from the bottom up — oldest first. Always leave at least 6 leaves per plant.

🏺 Basic Post-Harvest Storage

  • Root vegetables: store in dry sand inside boxes in a cool, dark place — last months

  • Leafy greens: wrap in damp paper and refrigerate. Consume within 5–7 days

  • Tomatoes: never refrigerate — loses flavour and texture. Room temperature until ripe

  • Herbs: hang upside down in an airy place to dry and preserve for months

  • Seeds for next planting: dry completely and store in paper envelopes inside sealed glass jars in a cool, dry, dark location

🎥 Watch: Harvesting and storing garden vegetables:

🌱 Survival Agriculture: Maximum Production in Minimum Space

For situations where space and resources are limited, these crops offer the highest caloric yield per square metre:

Sweet potato: one of the world's highest caloric yields per growing area. Resilient, productive and nutritious. Plant slips in any reasonable soil.

Cassava/Manioc: absurdly resilient — grows in poor soil, tolerates drought. High caloric productivity.

Pumpkin/Squash: extremely productive. One plant can cover 10 m² and produce 20–30 kg per season.

Corn + Bean + Squash (The Three Sisters): Indigenous intercropping system where all three crops benefit each other:

  • Corn creates support for beans to climb

  • Beans fix nitrogen in the soil for corn and squash

  • Squash covers the ground with its broad leaves — retains moisture and suppresses weeds

🧭 Golden Rules of Simple Agriculture

  • Start small — 2 m² well tended produces more than 20 m² poorly managed

  • Healthy soil is the only priority — everything else resolves with good soil

  • Observe your plants daily — problems identified early are easy to solve

  • Plant what you eat — the best garden is the one you actually use

  • Save seeds — real autonomy begins when you no longer depend on buying them

  • Failure is learning — every experienced gardener has killed plants. Keep planting
