Sustainable and organic gardening

Overview

The fewer artificial additives you introduce to your garden, the more sustainable it will be. Chemical means of enhancing your garden are a short-term fix and can be compared to giving your plants performance-enhancing drugs. Organic gardening focuses on naturally maintaining the long-term health and viability of the garden naturally.

Compost

Composting is the easiest way to make your garden more sustainable. Compost added as a side dressing or tilled into the soil of a new bed increases the water retention of the soil and slowly fertilizes.

How to make your compost thrive

  • Optimal compost recipe: 2-parts brown (dry leaves, hay, kitchen scraps, tissues) and 1-part green (plant clippings and weeds)
  • Add some garden soil. This will introduce the bacteria that help break down the organic material and make the soil healthier for the plants.
  • Water to 50% moisture (should feel like a damp sponge).
  • Mix every 2 to 7 days.
  • Cover to protect from the sun.
  • Add clippings of the yarrow plant and male urine (yes, that’s right!) to accelerate the composting process.
  • Do not put meat, fat, bones, or animal waste into the compost.

Achieving a natural balance

Organic gardening has a lot to do with maintaining a natural balance within the garden. In an organic garden you are likely to find some pests and diseases but these will be held in check by beneficial insects and controlled by the gardener.

Targeted approaches to solving pest and disease problems are better than applying broad spectrum herbicides, fungicides and pesticides. Research the problem and start with the least invasive techniques. Simply squishing, knocking pests off plants into soapy water or using homemade insecticidal soap may be enough to control pest problems.
