In our modern bubble-wrapped world where children are prevented from climbing trees, running in the bush, playing on a swing, swimming in a lagoon or even walking to school, the question is often raised ‘how safe are gardens?’.
If you take away all the snakes, spiders and all other creatures that may bite or harm, a garden will be left with soil, mulch, plants and created man-made hard surfaces such as decking, pergolas, play equipment, etc.
Soil itself is full of an array of macro- and microscopic flora and fauna that are critical for the existence of all
plants and animals on earth. It is these microbes we need to keep alive and thriving. However, within the soil there may also be some harmful microbes as well as heavy metals, depending on where you live. Gardens located close to main road systems (especially road verges), railways or manufacturing factories are likely to have high levels of some toxic heavy metals.
