Companion Plants Reduce Pests, Increase Pollinators, & Improve Soil
Plant the Companions Close and the Foes Far Away
Why do you need a printable companion planting chart? Experienced gardeners can tell us that there is a science to planning out a garden that goes beyond soil, sun, and water requirements. As it turns out, the arrangement of plants can have a big impact on the success of your garden. Certain plants can benefit from being planted together, while others might be detrimental to each other.
Plants that benefit from being planted together are known as companion plants. While it isn’t absolutely necessary to grow companion plants together, history has shown that there is significantly less incidence of plant disease and higher yield when they are grown together.
Lucky for us, experienced planters have passed on this information. Here is everything you need to know about companion plants, plus companions and “bad friends” to common garden plants.
What are the Benefits of Companion Plants?
- Repel pests. Some plants emit smells that have a repellant quality against damaging insects and other pests
- Attract pollinators. Pollinators like bees, butterflies, and birds are more attracted to certain plants. Some plants can’t produce fruit or seed without receiving pollen from one of these pollinators. Some pollinators also repel or prey on damaging pests, adding to their benefit.
- Improve nutrient quality of the soil. Certain plants are nitrogen-fixing, meaning they turn nitrogen in the atmosphere into a usable form that other plants can absorb and benefit from.
- Provide shade or support for other plants. Plants with sturdy stems provide good support for climbing vine plants, and plants with large leaves or dense growth can provide shade for plants sensitive to excessive sun exposure.
