Companion Planting

Companion Planting is an age old practice of Planting Plants within close proximity which will Benefit other Plants, either by giving off a scent or chemical that will repel harmful insects.

They may also be grown to entice Beneficial Insects that will help rid your plants of Nature's Nasties. Another way these plants may help is by returning goodness back to the soil. Many of these plants may also be used to make Teas to spray your plants with, or the leaves used in the Compost as an activated.

Thank you for the recipe to shoo the Red Spider Mites. Found the buggers on one of my Eggplants. Was going to heave the plant and re-do the soil, will give this a go now.

I read up on CP many years ago and must admit at the time I was disappointed with my efforts. I'm willing to be educated Dianne :)

I do grow a lot of Marigold but that is mainly because the broadcasted seed just loves to come up without any effort on my part. I have grown Basil with tomatoes but to be honest didn't notice any beneficial effect.

I am pretty lucky where we live, I grow a lot of Vegies and Plants that shouldn't grow here. I like to have a go at everything. It's probably the songs I sing to them at watering time that makes them grow. But seriously we have many different areas in our garden to grow different type of crops and plants.

Here is a Recipe for

Mealy Bug, Ant, Red Spider & Aphid Spray

3 litre container Mint, any Mint, these can be mixed varities

7 1/2 Litres Boiling Water

1/4 Cup Soap Flakes

Pour Boiling Water over Mint allow to cool completely then strain. Stir in Soap Flakes until dissolved and fill your garden sprayer, making sure to Label it.

All Mints are excellent Insect repellents, I grow mine in large pots that I grow my Miniature Fruit trees in and they both love it.

Done some of this kind of planting. I've found Parsley and Asparagus do fantastically well when together.

Some companions could be tricky in our climate: Broad Beans like the cool, Cukes love the summer heat so growing them together here around Briz might be a real challenge.

Nasturtiums (really they are Tropaolum sp.) are great trap plants for the white cabbage butterfly. They prefer the cool as do the cabbage-family plants but the butterfly doesn't appear until the weather warms up and both plants are dying off.

Companion Planting is a subject I am passionate about. Be it teas and sprays made with the weeds you find in your garden, or herbs you grow to use in the kitchen or as companions to your vegies as with Tomatoes and Basil, Nasturtiums with Cabbages, Cucumbers & Broad Beans and Marigold are one of natures Insect-repellants, to name a few. I would love to hear how other BLF Members Companion Plant.
