Healthy Soil = Healthy Plants

Growing your own delicious, healthy fruits starts from the ground up. Improve your soil, and you‘ll be rewarded with tasty produce and a plentiful harvest.

Healthy soil is rich in organic materials which encourages beneficial microbes that help to make the soil crumbly and active.

Healthy soil has:

  • Plenty of available nutrients
  • Crumbly loam texture
  • Good drainage - medium to high porosity
  • Good aeration - plenty of available oxygen

Plants take their nutrition from the soil so to keep them actively growing and healthy, nutrients must be replenished regularly.

This is done by:

  • Adding organic material
  • Improving soil pH
  • Including more nutrients
  • Working and turning the soil

Improved soil composition

Add organic material like compost and aged manures to:

  • Provide basic slow release feeding
  • Increase water holding capacity
  • Improve soil porosity (openness) which improves oxygen availability to the roots and drainage. O

Apply organic mulch like sugarcane or pea straw. As the mulch breaks down over the season, it adds nutrients to the soil.
And, at the end of the season, it can be readily worked into the soil.

Monitor soil pH

The pH (a scale of acidity or alkalinity where 7 is neutral, below 7 is acid and above 7 is alkaline) is vital to the success of your plants, because some nutrients are only available within a certain range.


For vegetables and herbs that’s slightly acidic - between pH 6.0 and 7.0.


To keep your soil at the optimal pH:

  1. Buy a pH test kit from your local nursery or garden centre
  2. After testing, adjust your soil's pH if required
  • To increase or raise your pH if the soil is very acidic, add garden lime.
  • To decrease or lower a pH above 7, apply compost, manure or sulphur.

Apply even more nutrients

Organic material slowly releases nutrients as it decomposes and breaks down.

Working and turning the soil

Over time, soil can become compacted and hard. This is detrimental to plants because it:

  • Reduces the air space in the soil
  • Makes it difficult for water to soak in
  • Prevents plant roots from easily penetrating the soil

Working the soil helps to break it up to:

  • Create pockets of air that are essential for plant growth
  • Allow roots to grow and develop
  • Let water penetrate down to the roots
  • Release nutrients and allow them to move down through the soil.
  • Encourage the return of earthworms and beneficial microbes
  • Lead to a soil that is healthy and alive
