Companion Planting

Companion Planting – Natural Pest Control For Your Garden

What is companion planting?

companion-planting-nasturtiums

Nasturtiums

Companion planting is nothing new. There is evidence of farmers using these simple techniques dating back to ancient Rome.

 

Certain plants attract insects to your garden. No – not more invading pests don’t worry! These plants attract beneficial insects. These beneficial insects eat up all of the nuisance bugs that have been feasting on your plants.

Some companion plants give off odors that the pests don’t like – keeping them away. Others offer a nutritional benefit to the plants they are nestled with.

Lastly some plants don’t do well when planted together, so companion planting keeps them apart at a safe distance.

Work With Nature To Get Rid Of Garden Pests

Companion planting is a pro-active approach to garden pest control. The plants create an environment which takes care of the pests before they devastate your garden.

Compare this with “normal” methods of pest control. You realize you’ve got a problem when you see leaves or produce full of holes. You grab some toxic brew to spray over the plants that you are going to eat!!

Which method makes most sense to you?

An added bonus with using companion gardening as natural pest control is that you can eat many of the companion plants. You can’t do that with chemical sprays!

  2. Greatly enjoyed the pictures of the plants being discussed. Just a list is great but as they say a picture is worth a thousand words.

    A question?
    Companion planting is done in close proximity to each other. On the reverse, what distance should be left between non compatable plants? Lets say potatoes and watermelonns.

    • Hi Bob

      I would plant them as far apart as you can, making it as difficult as possible for insects attracted to one to have an easy meal on the other.

      Also if you can, it would be a good idea to have some method of covering your melon plants later in the season when blight can be a problem. If potato plants are infected with blight the tubers can still be viable as they are somewhat protected by being underground, but fruits on the vine don’t hold up so well.

      If your summers are generally dry and sunny then blight shuldn’t be much of an issue for you.

      Good luck with your garden :)

      • Thanks the potatoes at their nearest are 8 to ten foot from the melon patch. As too location NE tennessee. Summers can go either way

  3. Cool, concise and informative. Nicely done. I do container gardening and am having a problem with what I suspect to be tomato psyllids this year – any ideas on how to control those on peppers (scotch bonnet) and tomatoes? I don’t do companion planting yet – but since last season I battled thrips and this season is psyllids – I’m starting to really think IPM and companion planting are something to look into for next season!

  4. Thank you so much for this incredible guide! The pictures help so much for a beginner gardner, like myself. This information is so valuable and really makes me appreciate my garden even more. Thank you!!!!

  5. I have a small garden. It is 11X17. I would like to put as much in the soil as I can. I am planting tomatoes in pots. Can I plant sweet potato on one side & cuke/squash on the other side with onions & galic in the middle?
    I will have herbs on the outside.
    Thanks

  6. I love love love this list! Thank you so much.
    I have looked it up again and again this spring since it’s our first year companion planting.
