Plant with tomatoes to improve growth and flavor. Basil also does well with peppers,
oregano, asparagus and petunias. Basil can be helpful in repelling thrips. It is said to
repel flies and mosquitoes. Do not plant near rue or sage.
BALM (Oswego, Monarda): Plant with tomatoes to improve growth and flavor. Great
for attracting beneficials and bees of course. Pretty perennial that tends to get powdery
GERMAN: Annual. Improves flavor of cabbages, cucumbers and onions. Host to hoverflies
and wasps. Accumulates calcium, potassium and sulfur, later returning them to the soil. Increases
oil production from herbs. Leave some flowers unpicked and German chamomile will reseed itself.
Roman chamomile is a low growing perennial that will tolerate almost any soil conditions.
Both like full sun. Growing chamomile of any type is considered a tonic for anything you
grow in the garden.
Improves growth and flavor of carrots and tomatoes. A friend to apples, carrots, tomatoes,
brassica (broccoli, cabbage, mustard, etc) and many others. Help to keep aphids away
from tomatoes, mums and sunflowers. Chives may drive away Japanese beetles and carrot rust
fly. Planted among apple trees it helps prevent scab and among roses it prevents black spot.
You will need patience as it takes about 3 years for plantings of chives to prevent the 2
diseases. A tea of chives may be used on cucumbers and gooseberries to prevent downy and
powdery mildews. Avoid planting near beans and peas.
Improves growth and health of cabbage. Do not plant near carrots, caraway, lavender
or tomatoes. Best friend for lettuce. The flower heads of dill are one of the best nectar
sources for beneficial insects in the garden attracting hoverflies, predatory wasps and many
more. Repels aphids and spider mites to some degree. Also may repel the dreaded squash bug!
(scatter some good size dill leaves on plants that are subject to squash bugs, like squash
plants.) Dill goes well with lettuce, onions, cabbage, sweet corn and cucumbers. Dill does
attract the tomato horn worm so it would be wise to plant it somewhere away from your tomato
plants. Do plant dill in an appropriate spot for the swallowtail butterfly caterpillars to
feed on. Even their caterpillars are beautiful.
Fennel is not friendly and is allelopathic to most garden plants, inhibiting growth
or causing them to bolt. It actually kills many plants. Dill is the only thing you can plant
with fennel. Other than that plant it by it's self. On a positive note the foliage and flowers
attract beneficials such as ladybugs, syrphid flies, tachninid flies, beneficial parasitoid
wasps and hoverflies Fennel is a good flea repellent. An old saying says to "plant fennel
near your kennel" to deter fleas.
Dried fennel leaves provide additional flea repelling
insurance when put inside the dog house or kennel.
Plant near roses to repel aphids. It also benefits apple trees, pear
trees, cucumbers, peas, lettuce and celery. Plant
under peach trees to help repel borers. Garlic accumulates sulfur: a naturally occurring
fungicide which will help in the garden with disease prevention. Garlic is systemic in action
as it is taken up by the plants through their pores and when garlic tea is used as a soil
drench it is also taken up by the plant roots. It has value in offending codling moths, Japanese beetles, root maggots, snails, and carrot root fly. Researchers have observed
that time-released garlic capsules planted at the bases of fruit trees actually kept deer
away. It's certainly worth a try! Concentrated garlic sprays have been observed to repel
and kill whiteflies, aphids and fungus gnats among others with as little as a 6-8% concentration!
It is safe for use on orchids too.
Plant in containers in the potato patch to keep away Colorado potato bugs. Horseradish
increases the disease resistance of potatoes. There are some very effective insect sprays
that can be made with the root. Use the bottomless pot method to keep horseradish contained.
Also repels Blister beetles. We have observed that the root can yield anti-fungal properties
when a tea is made from it.
Repels fleas and moths. Prolific flowering lavender nourishes many nectar feeding
and beneficial insects. Lavenders can protect nearby plants from insects such as whitefly,
and lavender planted under and near fruit trees can deter codling moth. Use dried sprigs
of lavender to repel moths. Start plants in winter from cuttings, setting out in spring.
BALM: Sprinkle throughout the garden in an herbal powder mixture to deter many
bugs. Lemon balm has citronella compounds that make this work: crush and rub the leaves on
your skin to keep mosquitoes away! Use to ward off squash bugs!
(Calendula): Given a lot of credit as a pest deterrent. Keeps soil free of bad nematodes;
supposed to discourage many insects. Plant freely throughout the garden. The marigolds
you choose must be a scented variety for them to work. One down side is that marigolds do
attract spider mites and slugs.
marigold (T. patula) has roots that exude a substance which spreads in their immediate
vicinity killing nematodes. For nematode control you want to plant dense areas of them. There
have been some studies done that proved this nematode killing effect lasted for several years
after the plants died back. These marigolds also help to deter whiteflies when planted around
tomatoes and can be used in greenhouses for the same purpose. Whiteflies hate the smell of
Do not plant French marigolds next to bean plants.
