The document discusses how to garden in an environmentally friendly way. It provides tips for reducing waste and using sustainable materials. Some key points include using compost and mulch to nourish soil instead of chemicals, collecting rainwater for watering, planting drought-resistant species, and creating habitats for beneficial wildlife like ladybugs and lacewings to naturally control pests. The overall message is that small actions like these can significantly benefit the environment while gardening.

remaining 4% are under threat due to demand for peat
from gardeners and growers. This demand is now
threatening to cause damage to peat bogs in Europe as
well.
Similarly, damage is being caused by moss collection
from the wild, for hanging baskets, rather than from
managed sources.
If considering furniture in the garden, an eco-
friendly gardener would ensure that furniture is not made using
hardwoods taken from the wild, but those grown in a sustainably
managed forest.
Consideration also needs to be given to the chemicals in
preservatives and paint used to treat and colour the furniture and
the implications these may have in contaminating the surrounding
environment.
