A little preparation makes planting much easier and helps establish the plants.
Soil
Nillumbik’s soils are known to be poor with minimal topsoil and clay below.
Indigenous plants are adapted to local soils so soil improvement can be kept to a minimum. Start by choosing plants that suit your soil type.
Loosen the soil with a garden fork (avoid turning over) to reduce compaction and allow deeper water and air penetration.
If your soil is heavy clay, you may consider adding:
- compost (helps improve soil structure and biology)
- gypsum (helps relax clay soils)
Use compost carefully. Homemade composts can be very nutrient rich and may contain seeds that can germinate around the plant.
Remove weeds
Remove weeds before planting as they compete with new plants for light, water, and nutrients.
No chemical weed control options:
- hand weeding
- sheet mulching with cardboard covered by mulch (smother weeds)
- solarisation using black plastic in hot sunny weather (cook weeds)
If you choose to use chemical weed controls, look for low environmental impact options.
Add organic mulch or grow living mulches
Apply a 7.5–10 cm layer of organic mulch, or use low groundcovers as a living mulch.
Mulch helps:
- reducing watering by hold moisture in the soil
- reduce weeds
- stabilise soil temperature
- improve soil biology, structure and chemistry
It is important that you use mulch that is free from weed seeds and waste that can reshoot
