Not all creatures in our garden are
enemies.
Some insects are helpful. Butterflies and
bees, for example, should be encouraged
because they pollinate plants; mantises
and ladybugs prey on harmful insects.
Most diseases in the vegetable garden are
caused by micro-organisms such as fungi,
viruses and bacteria.
Diseased plants will have spots or black,
yellow or white powder on the leaves.
If the attack is serious, the plants will
look as though they have been burned.
Diseases can also cause plants to go
mouldy.
Here are a few ways of dealing with
pests and diseases. They all use natural
materials and/or simple techniques that
will not harm the environment:
• Remove and squash any caterpillars that
you find in the soil and on the leaves.
• Remove any sick leaves and plants.
• Sow strong-smelling plants in between
your vegetables: plants like garlic, onions,
coriander and parsley all repel insects.
• Make your own bug traps: try covering
strips of bright yellow card with vaseline
or oil. Alternatively, fill yellow bowls or
containers with water. The insects are
attracted by the colour and drown when
they fall into the water.
