Organic Gardening

Organic gardening works with nature instead of against it. By building healthy soil, encouraging beneficial insects, and using natural remedies, you can grow healthy crops without synthetic chemicals.

Natural Pest Control Recipes

These proven home remedies help control common garden pests. Always test on a small area first and apply in the evening to avoid leaf burn.

Nettle Liquid Fertilizer (Brennnesseljauche)

Fill a bucket with 1 kg fresh nettles and 10 L water. Cover loosely and stir daily. After 2 weeks it stops foaming and is ready. Dilute 1:10 with water before use. Works as both fertilizer (nitrogen-rich) and aphid repellent. Smells strong!

Soft Soap Spray (against aphids)

Mix 15 mL pure soft soap (no fragrance) with 1 L warm water. Spray directly on aphid colonies, especially undersides of leaves. The soap dissolves their protective wax layer. Repeat every 3–4 days.

Garlic & Chili Spray (broad pest repellent)

Blend 4 garlic cloves + 1 chili pepper in 500 mL water. Let steep overnight, strain, and add a drop of dish soap. Spray on plants to deter aphids, whiteflies, and fungal spores. Reapply after rain.

Baking Soda Spray (against mildew)

Dissolve 1 tsp baking soda + 1 tsp vegetable oil + a few drops of dish soap in 1 L water. Spray weekly on leaves prone to powdery mildew (zucchini, cucumbers, peas). Preventive use is most effective.

Horsetail Tea (against fungal diseases)

Boil 100 g dried horsetail in 1 L water for 30 min. Let cool, strain, dilute 1:5. Spray on leaves to prevent blight, rust, and mildew. The silica strengthens cell walls. Apply every 2 weeks.

Organic Fertilizing

  • Compost is the king of organic fertilizers – it improves structure, feeds soil life, and releases nutrients slowly.
  • Worm castings (vermicompost) are even richer – use a worm bin for kitchen scraps. Mix into potting soil or top-dress beds.
  • Nettle liquid provides quick nitrogen for heavy feeders during the growing season (dilute 1:10).
  • Comfrey liquid is rich in potassium – great for tomatoes and fruiting plants. Same method as nettle, dilute 1:10.
  • Wood ash (from untreated wood only) provides potassium and raises pH. Use sparingly – 1 handful per m².

    • Beneficial Insects & Wildlife

    A healthy garden is full of helpers. Attract and protect them by providing habitat and avoiding pesticides.

    Ladybugs (Marienkaefer)

    A single ladybug eats up to 150 aphids per day. Attract them by leaving some aphid colonies early in the season – they'll come! Overwinter in leaf piles and hollow stems.

    Hoverflies (Schwebfliegen)

    Larvae devour aphids; adults pollinate flowers. Attract them with flat-topped flowers: dill, fennel, marigolds, chamomile. Plant these in or near your beds.

    Ground Beetles (Laufkaefer)

    Active at night, they eat slugs, snail eggs, and larvae. Provide shelter: flat stones, bark mulch, or a 'beetle bank' – a slightly raised strip of rough ground near the bed.

    Hedgehogs (Igel)

    A single hedgehog can eat 200 g of slugs per night. Provide access (gaps in fences), leaf piles for hibernation, and a shallow water dish. Never use slug pellets – they poison hedgehogs.

    Mulching

    Covering bare soil with organic material suppresses weeds, retains moisture, feeds soil life, and regulates temperature. The #1 low-effort technique for healthy soil.

  • Straw mulch (5–10 cm): ideal for strawberries, tomatoes, and paths between beds.
  • Grass clippings (thin layer, 2–3 cm): rich in nitrogen. Let dry slightly before applying to prevent matting.
  • Leaf mulch: perfect for autumn. Shred large leaves first. Attracts earthworms.
  • Living mulch: plant ground-cover crops (clover, nasturtium) between tall plants to suppress weeds and fix nitrogen.

    • The core principle of organic gardening: feed the soil, not the plant. Healthy soil grows healthy plants that resist pests and disease naturally.
