Prepare Your Organic Vegetable Garden: Soil, Compost & Natural Pest Control

Why Organic?

Organic gardening isn't a trend—it's a return to growing food without synthetic chemicals that persist in soil, water, and your family's bodies. The cost difference is minimal; the health and environmental dividends are massive.

Know Your Soil Type

• Clay: Forms tight ball, drains poorly. Amend with coarse sand, compost, and aged manure to improve structure.
• Sandy: Falls through fingers, loses water/nutrients fast. Build humus with compost and well-rotted manure.
• Loam: The gold standard—crumbles easily, holds moisture, drains well, teems with earthworms. Lucky you.

Start a Compost Heap

• Size: minimum 4'×4'×4' (1.3m cube)
• Layers: browns (leaves, straw, cardboard) + greens (veg scraps, grass, manure)
• Moisture: damp as wrung-out sponge
• Turn every 1–2 weeks for aeration
• Ready in 3 months—dark, crumbly, earthy-smelling

Leaf mold and straw are premier carbon sources.

DIY Organic Pest Spray

Garlic-Paraffin Oil Spray (repels cabbage moths, aphids, caterpillars, mosquitoes, snails):

1. Blend 4 unpeeled garlic cloves + 7 Tbsp medicinal paraffin oil → pulp
2. Steep 2 days, covered
3. Melt 1¼ Tbsp grated oily soap in 550ml hot water
4. Combine, refrigerate in sealed jars
5. Dilute: 1 Tbsp concentrate per liter water when spraying

Companion Planting for Natural Defense

• Garlic throughout: antifungal, deters many pests
• Marigolds border: repels nematodes, beetles, aphids
• Mint (contained!): deters ants
• Chives: repels aphids
• Wood shavings mulch: blocks slugs/snails

Incompatible Plant Pairs (Avoid Planting Together)

• Parsley & lettuce
• Fennel & tomatoes
• Tomatoes & peas / potatoes / cabbage
• Bush beans & onions
• Cabbages & onions

Feed your soil, diversify your plants, and let ecology do the pest management.
