Companion planting is simply planting two or more vegetables and/or flowers near each other for mutual benefits. Different plant species having the same soil and sun requirements, that repel insects or improve vegetable flavor when used as companion plants are eco friendly and make home gardening easier. Companion planting allows for a higher yield of produce in smaller spaces while making home gardens more aesthetically pleasing and aromatic.
Corn and beans are a good combo for companion plants. Same soil and sun requirements and the corn stalks provide a place for the bean vines to grow. Pumpkins and squash do well grown in the corn patch as companion plants.
Garlic should be planted throughout your home garden to repel insects. Plant garlic in your rose bed and near any berry beds to repel the Japanese beetle. The garlic will not flavor the berries, but it does increase the rose’s and berry’s essential oil production helping the plants to produce more fragrant roses and juicier berries.
Fragrant and colorful petunias repel a variety of garden insects and should be used as companion plants throughout the home garden.
Cabbage worms are repelled when the cabbage is planted with companion plants like potatoes, dill, sage, thyme, onions, beets, rosemary or lavender. Plant any vegetable in the cabbage family (broccoli, cauliflower, etc.) with the above mentioned companion plants.
Carrots benefit from having the companion plants of lettuce, chives, tomatoes and peas. Squash and peas make good companion plants, and squash will add nitrogen to the soil wherever you plant it. Nasturtiums thrive when planted near squash.
Sunflowers and cucumbers make good companion plants. Sunflowers do not produce much shade and the stalks gives the cucumber vine a place to grow.
Potatoes benefit from having eggplants as their companion plants. The eggplant acts as a trap for the potato beetle. Eggplants and beans are good for companion planting as well.
Plant basil and oregano as companion plants near your tomatoes will improve tomato flavor. Onions, chives, parsley, asparagus, lima beans, carrots and nasturtiums are also companion plants for tomatoes and for each other. Always plants these in close proximity to each other in your home garden.
While radishes are not pretty when growing in the home garden, their scent does repel insects, especially when used as a companion plant for lettuce and cucumbers.
If you only plant one companion plant in your home garden, make it the marigold. Plant marigolds around the outside perimeters of your home garden and in between your tomatoes vines. Marigolds are the workhorse of home garden companion plants, they work hard to repel a variety of above and below ground insects.
