Do companion plants repel cucumber beetles?

Utilizing companion planting can provide a natural means of protection against cucumber beetles that may plague your vegetable garden. Certain plants may confuse or even repel cucumber beetles, which is why I interplant them throughout my garden. These plants help reduce the number of cucumber beetles without the use of chemicals. Companion gardening can enhance the effectiveness of other organic methods you may be using. I recommend using them strategically to optimize your pest protection.

Plant companions at the proper time. I usually sow radishes and nasturtiums with my cucumbers, spacing them around every third plant. Plants that act as trap crops need to be sown earlier. For example, Blue Hubbard should be sown at least two weeks before cucumbers; the earlier planting helps capture and lure the beetles. You'll want to monitor trap crops every day and destroy any beetles you find.

Utilize companion plants in combination with additional tactics. I use them in conjunction with row covers. You can also add beneficial nematodes to the soil. Companion plants alone only partially deter beetles. They are most effective when used in conjunction with an integrated pest management strategy. Rotate the location of plants each year, thereby preventing beetles from becoming acclimated to descendants.

Steer clear of trivial errors. You should never position companions too far from associated crops. I continue to position companions at a distance of three feet. You should always have healthy plants. Stressed companions will not work as well. Water regularly. You should immediately remove any diseased plants. Companion planting typically requires a little time and attention, but it contributes to a safer overall garden space.
