How to Use Essential Oils in the Garden
The Use of Natural Aromatic Plant Oils for Garden Plants

 Natural plant oils can be used in
the garden for many plants; an alternative to chemical-based pesticides,
essential oils are the natural defensive mechanism
of a plant.
Plants contain natural aromas for a number of reasons; plant aromas found in the
bark,
leaf or root of a plant are present to protect the plant from potential harm.
Those plant
aromas found in the fruit or flower of a plant act as an indicator for plant
pollination.
Plant aromas found within the leaves of a plant contain the chemical component
terpenes; potential predators eating these leaves risk sickness or death.
Natural Plant Partners in the Garden
Many plants prefer the company of certain plant species for a reason; it is a
form of
natural defense mechanism against potential harm. For example, the herbs of
basil and
thyme naturally protect the rose species against potential threats, so are
commonly
planted together in the garden; vegetable gardens are protected by the presence
of
lavender and thyme.
Many pests and insects are deterred by the presence of certain plants, for
example:
• Ants – natural plant repellents are peppermint, spearmint and tansy
• Caterpillars – natural plant repellents are celery and tomatoes
• Mosquitoes – natural plant repellents are rosemary, sage, lavender and mint
• Snails – a natural plant repellents is garlic
• Slugs – natural plant repellents are chives and garlic
• Flies – natural plant repellents are rue, tomatoes and tansy.
The Extraction of Essential Oils from Plants
Natural plant aromas are commonly called essential oils; essential oils are
contained in
the veins, glands and sacs of a plant and extracted from various plant parts,
such as
leaves, flowers and roots. Essential oils are used in aromatherapy in the
treatment of
a number of potential ailments in humans and animals. However, once extracted
from
the plant, essential oils can also be used as a form of preventive medicine for
many
plants in the garden.
How Essential Oils Protect Plants in the Garden
Many essential oils have antiviral and antibacterial properties; this would
indicate that
the original purpose of the essential oils, when in the plant, was to protect
the plant
from viruses and bacteria. Therefore it follows that many of the essential oils
with these
properties are capable of protecting plants from disease if used in the garden.
The Use of Essential Oils in the Garden
Essential oils can be used as an alternative to growing compatible plants which
protect
certain plant species in the garden. Essential oils can be used by dilution in a
watering
can or watering system for garden plants. The use of essential oils can increase
plant
yield and enhance the flavor or fragrance of a plant; this is true of natural
plant partners
too. For example, growing basil near a tomato plant, or using basil essential
oil, enhances a tomato's flavor.
The following essential oils can be used as natural insect repellents:
• Ants – use essential oil of peppermint, citronella or spearmint
• Caterpillars – use essential oil of peppermint or spearmint
• Mosquitoes-use essential oil of lavender, lemongrass,citronella or tansy
• Snails-use essential oil of patchouli, pine or cedarwood
• Slugs – use essential oil of pine, cedarwood or hyssop
• Flies – use essential oil of lavender, citronella, peppermint or tansy.
