Companion Planting - Bountiful, Utah

  1. 1. J&L Garden Center The All Season Gift and Garden Center 620 North 500 West Bountiful, Utah 292-0421 2009 www.JLGardenCenter.com info@JLGardenCenter.com Companion Planting Many of us have heard that marigolds help keep insects out the vegetable garden; that garlickeeps aphids out of rose gardens, and that nothing will grow near a black walnut tree. Some ofthese claims hold true, others do not. Just where do these horticultural maxims come from? Companion planting is a mixture of folklore and scientific fact; you must experiment to findout what works for you. Even those who use companion planting do not always know why someplanting combinations work, while others do not. You will probably find that the most aromaticplants are the best companion plants for eliminating insects. For centuries it was common practice to plant two or more crops simultaneously in the same area to help increase theyield of one or more of the crops. American Indians used to plant corn, beans, and squash to their advantage. Squash leaveswould shade the soil and reduce weed growth. Their prickly stems would make raccoons think twice about entering the cornpatch. The corn provided shade for the squash in the heat of the summer and didnt mind if the vines wandered up their stalks.Beans were a nitrogen fixing plant. They provided the corn and squash with extra nutrients. In modern times single cropcultivation has become the most popular way of gardening because it is easier to plan and take care of. In nature, where plants grow without Avoid using invasive herbs, such as horseradish orcultivation, there is always a mixture of plant mint as companion plants, unless you are diligent in keep-types growing in an area.

As the emerging corn plants are weeded, the soilis gently mounded, or hilled, around the corn plants. Whenthe corn is about four to six inches high, bean and squashseeds are planted in the hills, Bean seeds are placed ineach hill, and squash is planted in about every seventh hill.The three crops grow together for the remainder of theseason. Interplanting has many advantages. Iroquois farmersadapted this ecological planting method to meet the needsof their crops. Several crops planted together are not asattractive to pests, while large plantings of one crop tendto have more pest problems. The hills provide support
