In keeping with National Herb Week, I wanted to focus on not just one herb, but many, so I chose
Companion Planting as the Herb of the Week.
Companion planting is placing complementary plants together so they help each other. When I first started gardening, I understood this concept from books and lectures I’d heard, but I do not think I was convinced it would really work. However my first garden was only 10 by 7 feet so if I wanted to put in everything I wanted herbs and vegetables had to be interspersed, so I tried a few companion planting ideas to craft my pairings and to my surprise, what I had read about really worked!
The reason this concept actually results in better gardens and plants is simple science:
- Some plants give off odors or chemicals that repel insects
- Some plants attract beneficial insects
- Some pants attract insect that will pollinate other pants.
- And some plants lure harmful insects away from valued plants
Here are some herbs that have companionship properties:
- Nasturtium repels aphids, squash bugs and striped pumpkin beetles, meaning it is great in a vegetable garden and mice in containers to keep other plants healthy.
- Catnip repels ants and flea beetles. I like it out in large garden patches that are away from the house in sandy soil which ants love.
- Chives is another plant that discourages aphids. It is also good at suppressing fungus. Perfect addition to containers.
- Feverfew will attract aphids, so you can place it near flowering plants aphids normally enjoy so they bother it instead.
- Yarrow attracts hoverflies lady bugs and wasps, all of which prey on aphids.
Experimentation is the only way to find the best companion herbs for your gardening needs, but here are some general guidelines to get you started.
