Benefits of Companion Planting

While at first companion planting may look like an odd idea to many gardeners, if you observe the benefits, it offers the same idea that will start looking exotic to you.

Moreover, if you have a look at the nature around you, you will notice that plants do not grow alone. They always grow in groups of different plants. Nature is a combination of plants from different species growing together. Therefore if you want to have a healthy garden, it is advisable that you choose the right set of companion plants. The benefits that companion planting offers is immense. Let us have a look at some of them.

  1. Companion planting saves a lot of space in your garden. Even if you have a small garden, you can grow a large number of plants if you wisely choose the companion plants.
    For example, plants that require indirect sunlight or need shady places to grow can be grown right next to plants that grow to be taller and require direct sunlight.
    The shady place would otherwise have been kept idle, or it would have been covered by weeds, but with knowledge about companion planting, you can use the entire area in your garden much more effectively.
  2. Another important aspect of companion planting is that since you can plant a greater number of plants in the same area, this will also help you in preventing soil erosion. The moisture of the soil can be locked up by the plants.
    If you do not grow the right companion plants, large places of soil would be left open in your garden. Therefore the chances of the soil losing its moisture also go up.
  3. Just like planting more plants in your garden locks up the moisture of your soil in a similar way, companion planting also helps you in preventing the growth of weeds in your garden.
  4. Companion planting also controls the attack of pests in your garden. Some plants are known to repel pests, and therefore growing them in your garden along with other plants will ensure a healthy harvest.
  5. When you have the same type of plants grown all over your garden, if anyone of the plant catches the disease, it spreads very quickly to the rest of the plants in your garden. Companion planting breaks your garden into different groups and therefore slows down the process of spreading disease.
  6. Companion planting attracts pollinators in your garden. Just like human beings are more excited when they receive different options in the food menu, pollinators visit the gardens with different varieties of plants in them.

  2. Legumes- Legumes like peas are good companion plants for cucumbers. Legumes release nitrogen into the soil, and the way increases the fertility soil.
  3. Dill- Dill is one aromatic herb that is said to be a good companion of cucumbers. Dill attracts pollinators into your garden and thereby increases the chances of natural pollination of your cucumber plants. Dill is also known to repel pests.

  5. Carrots- Carrots and other root plants grow well in the company of cucumber. Cucumber plants have one thick root, and the other roots are comparatively thin and do not spread more than 6 to 12 inches. Therefore root plants such as carrot can be grown in the company of cucumbers without being adversely affected by the roots of cucumber plants. They get enough space to grow beneath the soil, and the growth of these plants is not hindered by the presence of cucumber plants.
  6. Sunflowers- Just like corn supports a smaller and lighter variety of cucumbers; sunflower plants can also be used to vine cucumber plants. This also saves extra space in your garden and gives you the flexibility of planting different plants of your choice in the remaining garden.
