Over the years it has been established that growing various plants next to each other can act as a natural pest control. This can work in one of two ways. Either one plant will attract a particular bug away from the plant you wish to protect, or it will repel the pests by substances in its flowers or leaves. It has also been found that growing some plants in groups will result in stronger growth for one or both. This article from Golden Harvest Organics gives you the full picture including a list of plants and their relationship with each other.
Many plants have natural substances in their roots, flowers, leaves etc. that can alternately repel (anti-feedants) and/or attract insects depending on your needs. In some situations they can also help enhance the growth rate and flavor of other varieties. Experience shows us that using companion planting through out the landscape is an important part of integrated pest management. In essence companion planting helps bring a balanced eco-system to your landscape, allowing nature to do its’ job. Nature integrates a diversity of plants, insects, animals, and other organisms into every ecosystem so there is no waste. The death of one organism can create food for another, meaning symbiotic relationships all around. We consider companion planting? to be a holistic concept due to the many intricate levels in which it works with the ecology.
By using companion planting, many gardeners find that they can discourage harmful pests without losing the beneficial allies. There are many varieties of herbs, flowers, etc. that can be used for companion plants. Be open to experimenting and find what works for you. Some possibilities would be using certain plants as a border, backdrop or interplanting in your flower or vegetable beds where you have specific needs. Use plants that are native to your area so the insects you want to attract already know what to look for! Plants with open cup shaped flowers are the most popular with beneficial insects.
Companion planting can combine beauty and purpose to give you an enjoyable, healthy environment. Have fun, let your imagination soar. There are many ways you can find to incorporate these useful plants in your garden, orchard, flower beds etc.
